2012 SRT JGC Dyno issues with TCS/ABS/Autostick

[RonSSnova]

Hi all,

Need some help here as we are stopped on this dyno tune.
2wd dyno, we have tuned at least 5 other JGC SRT's without issue.
2008 - 2013, but this is the first 2012.

Our process is as follows:
Remove front driveshaft
Unplug transfer case control motor
Turn off TCS with the dash button, hold for ten or so seconds and it turns everything off.
Once we start tuning and making runs, we often have to use the Diablo handheld to turn Traction Control off.

With the exception of using the Diablo handheld (don't have one for this car) on this 2012 JGC, we have followed the same process.
We try a pull in 4th and the thing downshifts to 3, and we lose the autostick function. Trans stays in third.

Read here on the forum that we can set Displacement to 0 and this will do what the Diablo tool does.
We get the same result.

In order to get it out of this mode, we need to use a scan tool to clear the host of codes that come up.

I can post the tune tomorrow, I am presently at home, and the tuna computer is at work.

Help!

Well, we worked around this by using the Snap On scan tool to reset all the abs codes after each pull.
Not sure why this 2012 behaves so different. But it does.
On the 2013 I was able to remove the ABS fuse.
This car, the abs fuse also shuts off the fuel pump....

Sadly, the engine lost a lifter on the fifth run. Engine is stock with a procharger at 6 psi. The tuning was going very well....

I don't know about your 2012 specifically, but my 2014 SRT GC there are two ABS fuses. One for the main ABS ECU and another for the ABS pump. I pulled the ABS fuse for the PUMP iirc and it worked well.
So it MAY be that you need to try pulling the other fuse.
