CPU Communication with Gen 2 GTS

[Damion Green]

My car is in the shop right now, and it does not start, and the Dodge dealership has stated that they are having issue with communication with the CPU, anyone else ever had this issue?

I'd PM Dan Cragin. If anyone can get you pointed in the right direction regarding a CPU, that'd be the guy.

Consider giving me a call. 317-402-9013
There are several possibilities to consider before going too far $$$$.

Ya, Steve and Dan are your guys. I believe Dan can rebuild the Computer if necessary. I think he may still offer that service?

 

[Steve-Indy]

Yes, Dan is still the man for repairing PCM'S. I know of several successful cases in the past couple of years. Furthermore, he can supply a replacement if needed.

If no communication with a obd2 scanner to the PCM, PCM is most likely dead.

Search the Gen1/2 forum as there is posts about how to check stuff posted by Dan (@Viper Specialty ) and myself.

I am guessing you meant ->this<- Dan, lol

Short version, scan with scan tool. No comms?

Power on PCM C1 [Black] Pins 2 & 22, Ground on 31/32 with key in RUN? Yes?

PCM is dead. Contact below for a replacement. In stock.

I’m still around if needed for this, but Dan Lesser does it on a daily basis. I do have a lot of experience with Gen1-3 Performance calibrations.

Update: Turns out I the CPU was zapped. So the CPU in it was a Roe Racing CPU, I sent to the dealership the stock CPU, and when they plugged it in "Vrooom" it lit up. I may send the Roe CPU out to get fixed later this year tho.

I flew up there and drove it for a day, The Roe CPU added ALOT of chop to the car's idle. The OEM computer is super tame. The thing Im now contending with is the gear wine (whine?) is over powering and the trans needs rebuilt/replaced. So I stuffed it back in the NATMUS museum

What do you mean by a Roe CPU? Do you mean a piggy-back VEC2/3 or a stock ECU that ROE tuned?

It sounds like the later .... if they tuned it then presumably you arn't stock so you should go to a dyno to be dyno tuned with something modern like HP Tuners. If it's basical mods the stock tune is probably good enough for the time being; if you're heavily modified or f/i, stock tune could make the engine go boom.

The gear whine is most likely the rear end.
