CMC High RPM Fueling

[comnrailpwr]

Any plans to find the limiters in this ECM causing them to pull fuel at 3400 and not go over 4000rpm?

[Road]

Try this

[2007 5.9]

Try this

You can set them to 8000 and it doesn't matter, CMC pulls fuel 35-3700rpm. Only those who have CAX their own way, have high rpm.

[comnrailpwr]

Correct. Was hoping efi would work on a fix for this at some point. Would be nice to not have to convert ecms on these trucks.

They did for the CMD and CME controllers, so I can't see why not for the CMC. And yes I agree, not having to ecm swap would be very nice.

[GMPX]

CMC code is quite different to the later ECM's. I really struggled in many areas with the CMC ECM, it kept me up at night many times!!
Let me ask around :grin:

EVERYTHING needed is in EFI. No cax file or editing outside of EFI needed.

[GMPX]

Thanks Mike, good to know (I really wasn't sure myself).

[comnrailpwr]

So you are saying I can get 5000rpm full fuel with the CMC ecm with what is currently mapped out, irregardless of OS used and with CSP format? Because that's what I'm after.

Go to the fuel pressure tab and make it keep the regulator closed. You will need to disable the engine over speed fault too. Have any issues let me know.

[Mitco39]

Thats not what I found, I had to cax in a few things to have FULL fueling above 3700-3800rpm. Without the cax file I made it would only do around that mark, as many others had the same outcome.

The video i sent you last month had nothing changed outside of EFI Live

[Mitco39]

That video only hit 37-3800rpm which is the limit you will hit without outside changes. I was hitting that as well but if you sit on the dyno and hold a gear she will bounce off the limiter right around the same spot yours shifts at.

[comnrailpwr]

I haven't had a chance to test but yes I'm looking fo full fuel north of 4k. Preferably to 5k. I didn't think this was doable within what efilive currently has mapped .

The only other thing that i know that can be changed outside of Efi is the enabler for fuel control.

[Mitco39]

There is another way, smarty does that but I wasnt able to figure out how but I did find a hard limiter RPM that I was able to change in the bin via a cax.

[SASDakota]

I'm curious Mike, are you saying you can pull any MM3 you want out of the CM2100 with only EFI mapped params? Atleast until 3700rpm ish.

The only thing I can find EFI live don't have mapped that could help is the disable bit for fuel limiters and the hard limiter for the OS. And not for sure if those are in all of the OS. I personally have not took one much over 4k as the ones I have test are customers trucks but have no issues making power to 4k. Just had a 2007 dropped off today for a tune. I will do my best to get it sorted and report back.

[SASDakota]

I've seen the evidence that the hard OS limit will not let you get to 4000. It is a rather abrupt wall according to the datalogs.

We have a solution to high rpms via modifying the file outside EFI, just was curious if it was done another way IN EFI. And if it held full mm3 all the way out with current mapped params. I've seen a taper in fuel qty usually around 3000-3200 without intervention.

[comnrailpwr]

I cannot find any help with cax. I have searched and looked for classes. Asked around a bit but seems in the diesel community you are belittled for not being born with the knowledge. I'm a tuner. I consider myself pretty good and do my best. Have tuned most platforms of diesel using several products/softwares. Reading binary interests me but going at it without resources and alone is daunting and intimidating. I'm willing to put the time, effort and capital up for the tools to do so.

With that said i guess its back to a variation of the original question.

Does EFILive have any plans to find the limiters in this ECM preventing them from going full fuel to 5000rpm?

[GMC-2002-Dmax]

A CAX file is simply a notepad.txt file named as a .cax, it is created by the tuner and when the EFI-Live editor opens the calz file it also opens and displays the definitions in the CAX File.

There is not simpler way to explain it, it can only be created by someone who is able to find, identify and then create the CAX File, there is no secrets.

The information must be obtained, as in someone shares with you the hex address, the factor, offset and precision, or you have no chance unless you figure it out or can run IDA and disassemble code and reverse engineer code, that is what Ross does.

It sucks, but if anyone has info that gives an advantage, they don't share it usually.

[comnrailpwr]

So once a cax is created where is it put so the calz file when opened it also displays the cax? I remember their are also special naming of the .cax in order for efilive to open and understand it. What is a best software to use, winOLS, tuner Pro? I don't want anyone to hold my hand or share their work on the mapping itself. Just some guidance in the correct direction in getting to the point of finding it in the hex and then opening it in efilive once it's found.. Before long I would be running south a mile when all it took was one step north. I have worked with a .cax provided by fleece once to use their dual pump controller but cannot remember where that file was put and renamed to get the result I got. Do you know of any good dreading or research so I can better my knowledge on the subject?

[SASDakota]

When I was trying to learn how cax worked I read the entire CAX forum section front to back and back to front. Poked at a few files shared to understand the format. And tried to display data in EFI with a quarantined tune file. Spare PCM not a bad idea either.

But at the end of the day that is the easiest part of the whole thing. Finding the useful data is the daunting task. Tony/Ridgerunner just outlined what that entails. The CAX information already exists. Aside from the occasional bugs I and others have run into (mainly bitmasks) CAX itself is very straight forward.

Thank you. I'll venture over there and start reading. I have some but not front to back.

[GMC-2002-Dmax]

I use WINOLS.

So if the integer(s) are not specific to metric or sae values then its a bit easier, so if its something like a fuel tank gals or litres you need to denote the factors and offsets to display the raw values correctly in the editor by displaying metric or imperial values, some are not specific values and are raw numbers multiplied by a factor only.

The CAX File is named with the "OS Number.cax" and it is saved in the following WIN7 directory path

C:\Program Files (x86)\EFILive\V7.5\Calibrations

Here is an "example" of a simple single address value for LML files if EFI Live did not provide a gear ratio value and you wanted to alter that value using a .CAX FILE

Calibration definition extension for OS 12644094

The actual HEX ADDRESS would be where I placed XXXXXX's

Thanks Tony. That's the kind of information I was looking for.

I tried but could never find the limiter, it kept me up at night I can assure you.

Also, there is a sample .cax file in the EFILive installs located here:
C:\Program Files (x86)\EFILive\V7.5\Calibrations

The file is called 'Template.cax' and it shows every possible way to define a .cax, you can just view it in Notepad.

Important note, if people want to go messing around with files outside of EFILive or via .cax there is a very real possibility you may brick the ECM by defining something wrong, EFILive will not cover replacement licenses in these instances.

This truck I tuned on to day was hitting a wall at 4000 rpm. Fueling was no problem up to that point as I had issues with rail relief popping. This one had the 11551035 cal. Truck belonged to a dealer and had it sold so was unable to spend much time with it.

Having full 165mm3 up to 37-3800 was never the issue...it was getting past the "Wall" at 4k. Guys are spending thousands of $ to swap to a CMB and correct injectors to get full fuel PAST 4k. Most pulling trucks whether 6.7 or 5.9 based are 4500-5500 in range. 3700 wont cut it pulling and in fact is quite fatal to the lower end in a 6.7 based application.

It would be MUCH more cost effective for these guys to keep their CMC controller and get the full fuel to 4500+ that they can get with the other option.

I did it about a month ago. 6.7 CM2100 ECM running 4000+ rpm. That video I posted just above was 100% efilive only.

Unless of course you meant excluding CAX, in which case I do agree with you.

My definition of inside efi live is no cax needed.

If you need a cax than its not possible with just public release software.

That's my point, unless you know how to properly find, address and edit the bin, your SOL.

Thats the way everything is going, you either figure out how to do it yourself, or purchase "base" files with it already done so you can tune on top of it.

Which is precisely why this thread was started...the CMD and CME controllers have high rpm...we're simply asking Ross to look at it again for the CMC.

I know and have read that it was difficult for him the first time around, but being that it's the only controller without high rpm fuel...please look at it again.

I can't confirm on the other platforms, I only use efi for 06-17 trucks.

The "other" company doesn't have DTC'S avail for the CMC, so most don't bother with it.

As for the Mads platform, I can't say if they do or don't.

[comnrailpwr]

I have used the warp platform on a 12 and it would do fuel past 4k but have never sued it on the CMC controller.

[GMPX]

That is strange Mitch, at the time of testing this we had that defined but the problems still existed. I can re-enable it no problem but I hid the cal for the reason below...
It is in a VERY dangerous area of the ECM, if you don't load a modified bin in to EFILive and save the file (so the checksums are corrected) it will brick the ECM.....speaking from experience.
Also, from memory it is not in every OS, the earlier ones did not have it.

No, they have the same approach as you guys do for the dtcs (CMC, CMD and CME) vs just CMD and CME for Efi. So unless tuners can work in a deleted environment with the CMC, no real reason to invest time in finding limiters.

Very weird, I was rummaging around in there quite a bit and the ecm took every flash just fine. Basically what I did was rev out the engine and see what the hard limiter was, in this case IIRC it was 3850 and started looking for that in the BIN and started checking off the instances of it. I was finding the address's in winOLS and using a cax to modify them thus allowing efilive to do the checksums each case.

Now I have about 10 of these limiters cax'd currently and when I finally got it it was around 11pm after looking at it all for 15+ hours so I set all them to 5000rpm and tested it and got it. So I am not sure if all the changes are needed but i had no issues with bricking through and through. I guess I was just lucky then :)

So that will kill the nasty hard limit at 3,850 RPM , will they fuel beyond that with what we have in the software if I enable that calibration again?

Yep we took the hit for everyone on that. I have no idea why Cummins decided that an incorrect checksum in that area should cause the ECM to totally shut down for good :ermm:

[GMPX]

It is possibly just an enabler for the series of validity checks it is doing (like that limiter we are talking about). If it fixes the problem too then it must just bypass a lot of things.

[Mitco39]

So that will kill the nasty hard limit at 3,850 RPM , will they fuel beyond that with what we have in the software if I enable that calibration again?

I found that it would taper there was 2 or 3 other tables that I found were not in the existing .calz files and when I maxed those out I had no issues with full fueling. This was all on this single manual file, I have not tested on a auto file. But yes it would easily climb up and over that limiter. I am 90% sure that is all that is needed, but like i said I used a sledehammer and changed about 10 different addresses that had at or around 3850 all in one shot and got it, made a video logged it and went to bed lol.

[Mitco39]

Yep we took the hit for everyone on that. I have no idea why Cummins decided that an incorrect checksum in that area should cause the ECM to totally shut down for good :ermm:

I will say that this address I posted you cannot edit in calterm, it is a read only value. Which could be why only a very small handful of guys have been able to figure this rpm fueling out.

I'm adding in the boost sensor linearization table for the CMC so I can re-activate that 3,850 limiter (though I am hesitant knowing how dangerous it is).

[GMPX]

The checksum region this is sitting in has to be manually defined in the software by us (me), it is figured out using reverse engineering with IDA Pro. If I get something wrong then we have bricks all over the place, I can check and double check the data (which I would have initially) but it is still a calibration that does make me feel uneasy.

[GMPX]

All I can say is on this OS on this truck I have changed it and it did not brick or anything like that, haha.

So just to clarify though, on that OS 'just' doing that cal eliminates the 3,850 hard limit? Or did you do too many at once to know it was that one specifically?

[Mitco39]

I changed to many at once to know if it was one specifically, but I do know I found this read only value in another software and did confirm it changed when changing this one parameter. I can send a tester tune out with just the one changed and see what happens, it would be a bit though.

[GMPX]

Out of interest, these are all the additional limiters we had found in CMC (but decided to hide them) because we didn't know how to describe them or in testing at the time they made no difference.
What is shown as B9994 is the one you pointed out Mitch.

Wish i knew how IDA worked !

[GMPX]

Wish i knew how IDA worked !
Unfortunately IDA is only as powerful as the person driving it, it is essentially 'dumb', there is no magic button that it tells you what the code is doing.
If you want to work on LML then you need to learn Infineon Tri-Core CPU assembler like you know English (yuk!), for the Cummins you need to know PowerPC assembler at the same level.....no easy path :bawl:

Those 3800 RPM are limiters when there is fuel pressure errors (most likely the ones most are hitting). The 3900 is the engine overspeed limit Hyst. No ideal what B9994 is.

No not at all, you just have to read reviews on app stores to realise dealing with you guys on here is a dream :rotflmao:

I kind of feel bad that I had all those limiters in the software hidden for so long, I guess I have in my mind that when we add something in people expect to know what it is doing. In the case of those limiters we aren't 100% sure on them all so I didn't want to put them out there, but in the end if all everyone wants to do is put them to a number where they are not a problem and not worry about what they actually do then descriptions don't matter much.

[Dom_c13b]

I can't speak for everyone but most of the time we use other means to control max rpm, weather it be throttle tables or boost tables, etc. I don't think many people are using these limiters to control rpm for the most part. Again, just speculating on how I do things. Thanks again!

[2007 5.9]

Ross...while you are in there...can I ask for the "Boost Pressure, Voltage to Pressure Conversion" table be added to the CMC and maybe to the CMD/CME as well?

Its table E3255 for the CMB.

[comnrailpwr]

I second that les. It is very nice having the ability to scale the sensors on the cmb ecm. I have repurposed multiple of the factory sensors to do something different on competition trucks

[SASDakota]

The newer stuff converts Counts to pressure. A little birdie told me that the CMC charge pressure tables are on the way as well.

Just a question on this given it is a pretty big job to add these parameters in to ALL supported OS's.
Would it be fair to say that if I just add them in for the OS's that have the option to convert to CSP that would be ok? (Which I've already done).

These are all the OS's that have NO CSP option, is anyone using these on a regular basis that they actually need the extra limiters added in?

Works for me! I do not use any of those. All my customers trucks get a csp5 base, even for single tunes. I do that because of EDA.

[turbofamily]

Just a question on this given it is a pretty big job to add these parameters in to ALL supported OS's.
Would it be fair to say that if I just add them in for the OS's that have the option to convert to CSP that would be ok? (Which I've already done).

These are all the OS's that have NO CSP option, is anyone using these on a regular basis that they actually need the extra limiters added in?

Very fair proposition!

Yep me too....csp base for all tunes.

[Dom_c13b]

Same here, all CSP

Ok well here is an updated set of .calz files you can use to test with. These won't be included in the software installs yet until we get some feedback.
Includes the new limiters and also the boost sensor rescale.

Can I STRONGLY recommend you do some controlled testing before sending a bunch of tunes out to people if you have customers you need to update with these changes.

I would recommend updating to this release (https://forum.efilive.com/showthread.php?27992-Sep-2017-Release-Candidate-3) first, then copy in the .calz files from the attached zip.

Extract the attached zip in to:
C:\Program Files (x86)\EFILive\V7.5\Calibrations\CMC

Scale looks good Ross!

Awesome work and THANK YOU SO MUCH!

[2007 5.9]

So ross would you like a log of my truck that is on a limiter? Truck used to die at 3300, now it's at 3600.

New calz are set to 4500.

Not at the moment sorry Les, I don't have any magic bullets up my sleeve right this minute, I would have to go back and start digging again. Remember I added those years ago but had them hidden, it isn't something I just found.
Unfortunately I am currently working through TWENTY FOUR! new OS's for just the 2013+ Cummins ECM alone (because of the factory Ammonia Delete), these software engineers are out of control.

Actually, send the log over so when I have some time I don't need to chase it up again.

[2007 5.9]

OK well just let me know if/when your ready. Thank you

Awesome glad to know you are adding support for them, I had to deal with one a few months ago, what a mess.

[GMPX]

Yeah, it means my month is done for and then some!
There is two main issues now with the 2013+ that make it even harder, the factory Ammonia delete OS's add fuel to the fire and then the Cummins complier has had an error for a few years now where the 68RFE OS's share the same number as the Manual or Aisin OS's BUT the maps are in different spots. That causes confusion with EFILive so it means we have to map each new OS twice and detect which mapping version to use! Grrrr, should send them an Email asking for that to be fixed :hihi:

That was going to be one of the new surprises for you all, that was asked about recently so good timing. I've put it in for CMC but not CMD/CME at this stage.
I even used American spelling (https://www.collinsdictionary.com/dictionary/english/linearisation) for you all :grin:

Any plans to add this to CMD? Also whats the chance you can add the Fan tables to the CMD and CME?

thank you so much for this boost linearization scaling table. I'm not sure what the units of measurements are on the axis though. I understand the "inhg" one,but there is no label on the other axis and I can't figure out how to scale it for .05-5 volts for the sensor.

for a 5 bar sensor that is good to about 75 psi, the "inhg" axis should be scaled to 152.7 in hg, but how do I scale the other axis for .05v - 5v?

Thank you for any help!

Disregard, I figured it out.

[GMPX]

Sorry I missed your original post, scale it from 0 to 5V by taking the value shown and multiply it by 0.0048828125
Eg:
102 * 0.0048828125 = 0.49 V
920 * 0.0048828125 = 4.49 V
1023 * 0.0048828125 = 4.99 V

As you see the sensor must be quite linear as they are relying on interpolation between 0.49 V and 4.49V

Ross

thank you for replying. It dawned on my that it was probably already scaled for 0-5v from the factory and was just displayed in a different way than Volts. I changed a few of the search words I was using and was able to find the formula you posted in an Arduino forum that described that it digitally converts 0-5v to 0-1023 Units.

thank you Ross
