Thanks. Jesse has helped me out in the past, and I see that he's mapped out some stuff in the ECM, but I haven't seen any of the definition files out in the wild.

Any calibration definitions available yet for the E78 ECM or any other useful modules in the Chevy Volt? Just picked up a 2014 and would like to see what's available.
If you are accelerating with a high TPS value up to the top of a gear, then let off the throttle, the shift will skip a gear or two (or three) according to the upshift table.
While on the subject of MAP codes, if anyone here manages to update their 2007 ECM with a 2008 or 2009 OS without bricking it, be aware you will need to replace your MAP sensor with the new part for...
Where is this TPS hysteresis calibration value? I can only find the TPS upper cutoff value in my OS...
I just tried to access DVT for the T43 and got the error saying it's not supported. I'm running 7.5.5 build 84. Were you talking about a release that hasn't made it to the auto-update stream yet?
I'll keep you guys posted. I'm willing to post my PCB design, BOM, and source code, but I won't be building these things.
Plus it's moving very slowly due to no free time...
Perhaps someone could clear these parameters up for me.
I have three shift speed tables in my calibration (OS 24249179 CAL 24251803): Normal, Pattern A, and Pattern B.
Normal is self...
One more question: is there any chance of getting the parameters that define when each shift pattern is used added? I can modify the "Normal" "Pattern A" and "Pattern B" shift patterns, but don't...
Exellent! I will have to check it out.
Yukon runs great with the 5.3. Very smooth. Wintertime 0-60 time is in the low 6 second range:

Is there any way for EFILive to initiate a service fast learn adapt process for the 6L80e?
It is a virtual sensor. I don't think any of the Gen IV platforms have a hardware fuel composition sensor.
Looks like the AFM disable PID for 4LO active will not set, even when 4LO is actually active. I thought I had a 4WD calibration in my ECM? This testing was done with the vehicle stationary, and with...
Okay, here are my log results:
AFM Inhibit reasons:
Transmission gear incorrect
Transmission range incorrect
Those are exactly what I suspected- the 2009 ECM does not correctly read the...
Press the "complete history" button at the bottom left.
I don't understand what you mean by "it was correct". Put your VIN in, choose the TCM from the list of modules, and click the button to view the entire change history. That will give you a list of...
Here is the CAL ID for the fix on the 2007 controllers:
24239571 - New calibration to correct 4-5 upshift flare
Put the VIN in here:
http://tis2web.service.gm.com/tis2web
And see if there are any updates that mention the flare fix.
Yeah, I was wondering about the vibrations. We are missing the damped motor mounts that the AFM engines come with, so I'd imagine this could be a problem. Is it a specific frequency that is a problem...
I've emailed support about this, but in the interest of saving time, here goes:
Has anyone been able to tune their 6L80e from a 2009 Tahoe? Particularly one with TCM OS #24249179?
I think there is a GM software update that corrects this issue. Is this a 2007 operating system and calibration?
My trick for calibrating an installed wideband on a car with a cable actuated TB:
In park, run the engine up close to its rev limiter.
Turn off the key.
At the same time, open up the throttle...
My theory for the 4LO issue is this:
The ECM depends on a message from the TCCM to determine if the vehicle is in 2WD or 4WD. Since the 4WD state invalid flag is set in the AFM disable PID, I'm...
Ross, thanks for the update. I'll find out what's disabling AFM in my application and post back.
Yes, the engine hardware is 2007 model year, the ECM is just loaded with a 2009 OS and calibration.
