Upgrading to an EFILive custom O.S

[GMPX]

Here's a run down of the steps involved to make the transformation to an EFILive modified PCM Operating System (O.S).

First thing, all custom O.S's have NO calibrations in them simply because it would be near impossible for us to cover all possibilities of what might be needed to be flashed in on a vehicle by vehicle basis. So these are the steps that need to be taken.
This is based on a scenario that you are not doing a year or total O.S change.....i.e 1999 to 2001 etc.
Think of this as though you had a 2001 Camaro and you were upgrading that to one of our O.S's to suit a 2001 vehicle.

Step1 -
Read the existing tune in the PCM (or at least have a copy on hand if previously read), take note of the GM Operating System number.
The files that we currently have modified are -

GM O.S = EFILive O.S
2001 Programs
12202088 = 01250001
92111922 = 01250001
12208322 = 01270001
12225074 = 01290001

2002 Programs
12209203 = 02010001
12212156 = 02020001
12221588 = 02030001
12593358 = 02040001

2003 Programs
12579405 = 03150001
12593058 = 03190001

2004 Programs
12585950 = 04072901
12587603 = 04073001
12592425 = 04073101
12587604 = 04110001
12592433 = 04140001

2005 Programs
12592618 = 05120001

Step2 -
Find your matching O.S number in the above list and load the EFILive .tun file.
Do a full flash of this O.S into the PCM.
Once finished, the PCM will be left in a no start state, this is where you need to flash just the calibrations in from your original GM O.S.

Step3 -
Load your old tun file from the original O.S and just flash the calibrations in.
Once this completes the PCM will be in a state where it could start and run the engine, but don't get too excited just yet, there is a few more steps.

Step4 -
Read the PCM again, why?.
This will now read the modified O.S with your calibrations.
Once done you can save that .tun file as the new base file for the vehicle.

Step5 -
Important!!
Looking at your new .tun file checkout the values in the "EFILive Custom Calibrations" section and confirm they look 'sane'.
The reason for this is GM sometimes fill blank areas of the flash chip with either '0' or '1' which alters the default setting the new parameters will be set to.
I suggest setting the new parameters like so (for now) -
A0000 = Disabled
A0001 = 100%
A0002 = 100%
For further info on these, see this thread -
http://www.efilive.com/forum/viewtopic.php?t=1653

It would be a good idea to reflash your new .tun file again after it has been saved (even if you made no changes here) to ensure EFILive corrects the values in the PCM that are used by A0000 - A0002.

If you are upgrading a 1999 or 2000 O.S to a 2001+ O.S then you will not be able to use any existing .tun file you may have for your 1999/2000 vehicle.
You will need to obtain a stock (or modified) .bin or .tun file to suit your vehicle.

ATTN Beta testers - Any previous versions of 01250001, 01270001 & 01290001 will not be compatible with the .cal files that can be downloaded with these O.S's. contact me ross@efilive.com for further info on this.

Next in the pipeline for this set of mods is th 2002 F-body and C5 O.S's.
These should be ready for download within a few days.

At this stage I would encourage all 1999/2000 vehicle owners to upgrade to a 2001+ O.S, we just cannot implement some of the features we have planned into the 1999/2000 O.S's, so at some stage you folks might feel you are missing out.

Here also is some links for .tun and .bin files that might come in handy -

F5 F5 F5 F5....

Starting to get excited :!:

Custom OS's and Auto-Tune. That's almost too much to deal with in a single week :wink:

[GMPX]

I was 'hoping' to get the valet mode in this round of releases, but that is a major job, it's a rewrite (in assembler) of the speed limiter routines in the PCM (both cable and ETC throttle) across lots of GM O.S's, all of which are different (where is the sighing emoticon?).

Anyway, this lot should get everybody going MAFless.

Ross

Yuck, Assembler :!: I did some Assembler programming quite a while ago. Don't miss that at all! Prefer C myself.

I am just really keen to get the twin spark maps. I'll be upgrading as soon as they are posted.

Custom OS uploaded, instructions are spot on, and the radio still works afterwards :wink:

It doesn't get any better than that.

Nice work Ross!

[SinisterSS]

If you still require your radio to work, you need a better sounding exhaust system. :D

[SS2win]

Installed really easy... now is there going to be a 2 bar tutorial or will that be a seperate OS altogether?? :D

[VortechC5]

Ross,

Do the custom operating systems have the EPA readiness tests like the stock operating systems do?

[GMPX]

Ross,

Do the custom operating systems have the EPA readiness tests like the stock operating systems do?

Yes, basically what we are doing is taking the portion of code we need to modify, in this case the Octane Scaler routine and modifying it to our needs, the rest of the PCM code stays as GM had it.

A 2bar tutorial, yeah that is needed isn't it. :oops:

And we need commercial version to do this?

Correct.

Question on the upgrading my OS.


I have a 99 5.3L truck. With commercial version I can upgrade it to a 2004 O.S. and just use a bin from that year? or exactly how does it work?

You 99 and 00 will love the 01+ OS especially if you are running SD

You can only go as late as GM went with that PCM, 2004 used a different PCM, as did 2003 trucks.
For your 5.3L truck I think 2002 is as late as you can go.

I've just finished off the 2002 O.S's and they should be posted up for download in about 12hrs time (it's midnight here!!).

It was one only used in Australia and only on 'some' Utes, it's pretty much 12202088, it was phased out pretty fast with 12225074.

Hi Ross,

I saw a post of yours in another thread that mentioned that the 2003-2004 custom OS's would be available soon.

Are these OS's intended for certain vehicles. Could they be applied to a Holden, and would there be any benefit (additional functionality in the base OS, etc.)?

Can ya tell I'm an IT guy, gotta have the latest OS :shock:

Ahh, you IT guys, service packs and patches you live for!!.

If you have a VT - VYII then you can only use an O.S intended for a 512K PCM, in this case, 01290001 is the latest for that range, for VZ they used a different PCM so you couldn't use the VZ O.S in your VT - VYII PCM.

Cheers,
Ross

[Tordne]

Well, in that case I am already on the latest and greatest, including service packs! My work is done!

On another topic, how long did it take you to tune you car MAFless. I am using the auto-tune feature which is really simple, but I have this flat spot during acceleration in 3rd gear (manual) which I am trying to find/fix. Did you get anything like that?

Cheers.

So far it's taken me about 8 months!!. Simply because I do very little driving (maybe 100kms per week tops), usually I am in a rush so I never bring the 'tools' to tune, then, I really just don't have time to spend alot of time messing about.
What I did do was get the WOT done on the dyno, did some Auto-Tune for the part throttle and got the idle sorted, it needs more attention but for me, I living with it.
If I get to spend time tuning it's usually testing something.
No flat spot for me in 3rd, mines an Auto :lol:
Check what the timing is doing, is it pulling heaps out at some point?.

Hey guys,

I have an 00 C5 m6 tranny with current OS: 09381344

Can I DL and use any of the custom OSs already posted to the main website? I upgrade to commercial several days ago and am itching to get my MAFless SD tuning started.

Thanks!

[Dirk Diggler]

Yes you can use any 01+ OS.

[BowlingSS]

And we need commercial version to do this?

Any hope for us other users?

Bill

[Tordne]

Because you have to flash in an entirely new OS the only option is to use either the Commercial or Workshop versions, as they are the only editions that can perform the full flash operation.

If you can find a kind sole with either of those editions they could flash in the custom OS, and then you would be able to change the calibrations using your Personal version as you do now. Or at least that is the way I understand it.

Cheers.

Use any of the 01 - 02 files, just make sure you can get a suitable GM calibration to flash back in.
From 2003 on for US vehicles they changed up to a different PCM, but we will warn you if you try to flash in the wrong thing.

I am new to the EFI community and have a question. I have a 00 WS6 TA and am not sure what is meant by:
"If you are upgrading a 1999 or 2000 O.S to a 2001+ O.S then you will not be able to use any existing .tun file you may have for your 1999/2000 vehicle.

Sorry to sound like a newbie...BUT I AM

The issue is the 1999 & 2000 PCM O.S's were sort of unique enough to be quite different to the 2001+ releases, which makes it very hard to 'adapt' a 1999 calibration into a 2001.
If you have not already done too much tuning on the car yet then use a tun or HPTuners bin from from a matching 2001-2002 WS6 (looking at your user name I am assuming you have a WS6?).
If you are going MAFless then it is pretty much mandatory you upgrade to a 2001 O.S or even better EFILive custom O.S (so you keep the twin spark tables), because the 2001+ programs did not use 2 VE tables.

Hope that helps.....

Anything you want to share as a teaser? The $150 upgrade cost was well worth it, even for us poor Kiwi's that have to pay 1.3 times that amount (damned US currency being so strong). You get so much more functionality for next to no cost.

P.S - Newbies are welcome here too, we all have to start somewhere.

So I should be able to determine my GM O.S. number for my '00 WS6 TA? I just noticed at the top of this sticky that the year starts at '01. I have not done any computer tuning at all yet. What would be the "recommended" 01 WS6 tun file for me? The only mods I have done are Hypertech. I have changed to 160 stat, changed shift firmness and raised RPM between shifts, I added the "power tune" which probably doesn't do a darn thing. The only major chages I have done to my car so far is TCI 3000 stall converter and added BGRam air kit to my hood to make it more functional. I also added the lid with K&N filter, Have SLP Y pipe but its not an OYP. with QTP electric cutout in the I pipe.

[87gmc]

Questions on updating a 99 O.S. to 02 O.S. If the truck is bone stock is there any benefit updating it to a 02? I know for instance the 2000 truck gained 10 hp over the 1999 didnt know if was just tuned different or if was something mechanical they changed. It was just a curious questions.

I plan on using a custom o.s. when the ones come out where you can adjust afr at any given rpm along with map :D

[HioSSilver]

What's the purpose in the efilive o.s.?

[Tordne]

Basic summary below:

Only Version 1 OS has currently been made publicly available at this stage - 2 & 3 aren't far off

Version 1 - This will include the following -
Dual Spark Mafless with Octane scaler control.


Version 2 - This will include the following -
Dual Spark Mafless with Octane scaler control.
Valet mode speed limiter selectable via a toggle switch.
Two Step Rev Limiter for NON ETC cars.

This version is perfect for those who still want to run with a MAF and don't want to have to do a retune as you will have to do with Version 3.

Version 3 - This will include the following -
Dual Spark Mafless with Octane scaler control.
Valet mode speed limiter selectable via a toggle switch.
Two Step Rev Limiter for NON ETC cars.
Full RPM vs MAP Commanded AFR table with one really neat trick!!.
2 OR 3 bar support (up to about 26psi of boost with 10kPa,1.5psi increments) plus a boost timing table.

[HioSSilver]

the 2 step sounds cool

[87gmc]

is there something wrong with the 01270003 tun?

This version of the EFILive Tuning Tool has not been
configured to display this PCM's operating system.

Unregonized PCM

This may occur if...
your PCM has been updated by a GM dealer
to fix a software problem in the PCM.
OR
you are attempting to load an EFILive custom PCM
program without installing the matching *.cal file.
OR
you are attempting to load a non-EFILive custom PCM program.

Please save this calibration's *.tun file
and email a copy of it to: support@efilive.com
so that we can add support for it.

hi new to the efilive stuff trying to cruch all this into my head just got a commercial system whats diff about a custom efilive o.s. trying to lurn all i can befor i dig into the twin turbo 582 i have to tune hoping i can do it with out any problems trying to lurn some on my own 8.1 with out pissing off the wife tosting some thing lol been reading lot of the post and the forms and datalogging my avalanch trying to lurn lot diff then the gen 7 or fast systems i have used any way just trying to figure out what the custom os is about :Eyecrazy: thanks

[deezel]

Hi. The custom OS's allow full speed density or open loop tunes with dual spark maps and functioning octane scaler. They also have expanded VE tables, along with a few other extra tables to help with boosted applications.
Keep us updated on your 582 project.

[69camaro5speed]

thanks so i see the efilive has custom os under file i looked at one is that where i pic them from and how do you know whats what allso on the autotune does that change the ve table to match your air fuel as you drive or do you have to datalogg the info and lay it over and make changes

[69camaro5speed]

I can't find that OS #. I'm going to assume that it is 12212156 in which case the correct custom OS for your stock OS is 020200xx series.

Apologies if this is not what you are asking.

From memory that O.S was used on the E85 Fuel trucks, we never did a custom O.S for that one. In the many months they have been out you are the only one that has ever asked!.

:Eyecrazy: WOW lots of information to absorb. I have 00 WS6 and now I understand that I need the commercial version. No problem...I am ready to upgrade. I saw where the OS has different versions. Which OS year/version is the latest I can use and should I upgrade in small steps (ie. 00 to 01 to 02) or should I just jump from 00 to the latest and greatest...Yes I am I.T. guy too and have to have all the patches and SP's:exactly: Will the newer OS be easier to do the WBo2?
It was also mentioned that "EFI will have some very, very neat stuff in the final stages of testing right now that will make the commercial upgrade well worthwhile"... what is the "neat stuff" and should I wait a bit before upgrading??
I have also noticed that a lot of people like the dual spark map. Why is it better than single spark map?
On a side note what WB02 is best? I have been looking at the LC-1 and it looks good to me. Does the display from the cable readings display through the laptop or do I need a seperate display?

I would say you could probably update to the 2001 or 2002 OS used in the WS6. I'm not 100% on that though (we only have Holden's down here).

There is very little difference (generally) between the 2001 and 2002 OS. I have checked several and they all have the same tables. I know exactly where you are coming from being an I.T guy, I am too :). These OS's are not like your PC OS's so don't try an compare them ;)

Tuning with a WB02 is easy in al OS's, there is nothing specific in the custom OS's that affect your ability to tune.

Neat stuff that I am aware of:
- Throttle position referenced fuelling
- Custom OS for NOS (N20)


I have also noticed that a lot of people like the dual spark map. Why is it better than single spark map?

Basically because it restores the ability to have adaptive spark maps while running speed density (MAFless). If running speed density on the stock OS's you only have the low octane map referenced.


On a side note what WB02 is best? I have been looking at the LC-1 and it looks good to me. Does the display from the cable readings display through the laptop or do I need a seperate display?

The LC-1 is fine, a lot of guys use those cause they are a pretty good price. Basically what happens is that you wire the wideband output into the FlashScan unit and then log a PID that brings that data into EFILive (your laptop) logs.

Hope that helps a little...

ws6togo,

take one piece at a time, and "play" with the software alot;
read a tuturial and do a "dry run" first, understand all the steps;
when you're not sure about something, ask questions until it's clear;
there's a bunch of nice people here who are willing to help out...:rockon:
run the scan tool alot and check out as many PIDs as you can;
you'll do well, no worries mate.

Cheers,
Joe

Thanks, Its people like you, Black02SS, and others that make working with tuning cars a lot easier. I can see why more and more people are going to EFILive !!

Basic summary below:

Only Version 1 OS has currently been made publicly available at this stage - 2 & 3 aren't far off

Version 1 - This will include the following -
Dual Spark Mafless with Octane scaler control.

Version 2 - This will include the following -
Dual Spark Mafless with Octane scaler control.
Valet mode speed limiter selectable via a toggle switch.
Two Step Rev Limiter for NON ETC cars.

This version is perfect for those who still want to run with a MAF and don't want to have to do a retune as you will have to do with Version 3.


Just to clarify, if it's "MAFless" why do you still want to "run with a MAF", and as for "dual spark", that's 2 tables, not 2 flashes of the plug per compression stroke, correct? How does one select the alternate spark and the Rev limiter settings? Thanks!

The section I copied was a copy of a post that Ross made in another thread...

There is no alternate spark maps as suck, just that both the High and Low Octane maps will work in the custom OS's when running MAFless (Speed Density), whereas with a stock OS running MAFless it would only use the Low Octane table. I'm sure you knew that already, but just for other peoples benefit ;)

The Valet Mode/Two Step (Rev Limiter) tables are:
A0011 - To actually enable the function and requires that you wire a switch into a particular pin on the PCM
A0012 & A0013 - Speed limit for ETC or cable throttle controlled vehicles when in Valet Mode/Two Step
B3324 & B3325 - RPM upper and lower limits when in Valet Mode/Two Step

hey everyone.
im completely stupid to this concept so sorry for the questions, i have recently changed from jetdst tuner to efi live. an amazing difference!! :)
anyway where can i get these files or how do i modify them. i am looking at running nitrous and need to figure this all out. how do i change the calibration files?
The list says that my calibartion is 12592618. so what do i do here? please email me asap if possible kinda stuck here till then. hemi_power_3@hotmail.com

hey i have a 2005 gmc sierra 4x4 4.8

[lhomert]

I got a 2001 2wd 2500HD that I use for work I stay busy working on it when I'm not working it. I just ordered EFIscanandtune I'm excited about that, I hope I can figure it all out I'm ok mechanically but electronics are new to me oh well you only live once.
