CM2200 Development/Updates

[SASDakota]

2010+ Cummins has been pretty dark on updates lately compared to the first few months from announcment.. Any talk of more support? :music_whistling_1:

-Exhaust brake TQ
-Fuel/TQ/MM3 limiters
-Transmission parameters (converter lock/unlock, shift point, shift timing, throttle axis, line pressure control and ramp rates, etc..)

[cindy@efilive]

With the release of CSP, we expected to receive a range of EDA logs to demonstrate the need to additional parameters/limiters. At this point in time we've received one log/request on an extremely built vehicle that is not representative of most of our customer base. It will still be addressed, but not immediately.

Cummins will sit to allow customers to digest the data we've provided, and over time we expect to receive a range of logs/requests and manage them all together. Trans tuning will be addressed as part of that review. Logs and requests can be email to me.

Cheers
Cindy

I have been quiet until now thinking I was just going to be a pest.

But if logs is what you need I have lots of them showing limiters in play and so forth. Cindy, I will send an email and a short handful of logs with some basics. Please let me know if there are specific data points you guys need me to shoot for. I do anything from daily driver, towing 14k, and occasional street playing.

Thanks.

[cindy@efilive]

A pest is demanding those parameters just because you think you need them without providing reasons or data. Good development is driven by logical data. Logical data is not emotional and isn't skued to an agenda.

Send them through so we can review and prioritise the requests.

I don't have a time line for you, but I expect development won't commence this side of October. Ross is currently implementing support for 2 new GM Diesel controllers, and we are heading into that time of year where we start to add support for 2016 OS's on already supported controllers.

So does EFI live still plan to support 68rfe parameters on the 2010+ rams? I am honestly a bit worried now that we are going to get left behind because all the shops clearly have the ability already and efi is making sales because of it. I want to voice my need/want for trans adjustments to make sure we are heard. Just hope I am not the minority.. Have a handful of trucks running tuned with stock exhaust and some with big tires. Really need shift logic/shift timing/line pressure adjustments.

I came from MCC and with the narrow view we had into trans logic I still had the truck acting better than it does currently.

[30 RUM]

Sasdakota you are definitely not the minority wanting the added parameters. We all want them, I have countless people that want to switch from Mcc, but when one can't adjust trans tables on a 7k transmission I tell them to stay with what they have.

[WyoFreeride]

I am in the same boat. Several trucks in my area would ditch MCC (myself included) in a second if there were Trans parameters available. Anything much over stock and they need it to live, imo.

I also hope there is still some extra RPM in the works, as its deperately needed for competition applications.

I wish I had the tools available to spend time tracing code and helping the effort, but a dissasembler and the hardware to go with it is out if my budget unfortunately. If there is any need for that, I'd gladly volunteer time.

We are on the other side of that fence, we need a truck sitting in the driveway to test it all on :grin:
Probably nothing going to happen on the trans for 2015 but we plan on revisiting it Q1 2016, we've had to play catch up on the GM side of things as the 2016 models have been rolling out since July/Sept.

[LPDTuning]

I'm def in the same boat with the trans tuning. Even a stock truck feels like a rocket with added line pressure and an earlier lockup schedule. Not to mention some ability to lessen the torque management. Hoping that option comes to us more sooner than later. Not to get off subject but has anyone addressed the speed limiter issue for the 13-15's? Or is that in the trans parameters also?

[SASDakota]

The earlier lockup is what makes it feel like a rocket. These new PCMs calc load and apply fueling based on that. Trans tuning and more fuel control is desperately needed on the 4th gens!

So, I have seen a couple company's advertising trans tuning is out. When can we expect a pre-release so we can play around with this stuff?? :drool:

Just curious, who is saying trans tuning is out? And where are you seeing that?

[2007 5.9]

Many tuners have trans tuning, but it's not from or supported by EFI...much like the Off-Road tunes bring sent out

[rbp4u]

It appeared to me Calibrated power had a EFI based trans tune. I could be wrong though. I am aware that others are using other means to tune the trans.

[GMPX]

Trans will be getting worked on soon enough (what a mess it is), but 'off road' tuning will not and cannot be offered to US customers, sorry we don't make the rules.

The trans tuning we're offering was written into EFIlive entirely using .cax definitions. Don't put Ross and Paul on the hook for it - there's nothing in beta.

Sorry guys, based on this post I guess I was overly optimistic that it was getting close. Not trying to stir anything, just anxious to see what the EFI side of trans tuning will look like.

[SASDakota]

Is Q1 2016 still on schedule for CM2200 development? Also, will we ever see a DTC list for CM2200-2350? Not emissions junk but Intake Air Heater, VGT module, active air, etc would be nice to turn off.

[GMPX]

Trans tuning is being done on the CM2350B first and is about to move in to beta, then I will go back and do the CM2200 trans stuff.
Not sure on the DTC's, because we never intended to offer them I have not looked in to how it works. On GM for example it would be tough to exclude specific DTC's from a list, however Cummins from what I hear is quite convoluted so it could be worse, sorry but I can't give any sort of firm answer on this question. There might be some switches in the software to disable VGT controls (as an example), but I don't know if that automatically stops any VGT related DTC's setting.

[SASDakota]

Gotcha, sounds promising for transmission side of things!!

I second this. I get asked all the time about control of these features.

[vortecfcar]

Removing any of these qualifies as tampering with emissions equipment.

Thanks Nick, sadly that is the case.

[SASDakota]

Turns out my truck was perfectly happy with modified VGT so no need for that extra support :)
