Hey guys, I can't seem to figure out this issue, and it's driving me nuts!
I've been driving my 04 GT for 9 months / 16k miles. Here's my current setup:
04 Grand Prix GT
04 CompG Motor
04 CompG 3.29 Trans (Valve body / Channel Plate replaced with GT parts)
04 CompG Harness (Modified to connect to the GT EBTCM)
04 GTP Base OS, 04 CompG Trans Tables
04 GT EBTCM (Stock for this car)
This setup works 95% perfectly, and I've put 16k on the car in the last 9 months. The only existing issue is that the 04 GTP has a different EBTCM then the GT, and this is causing the TCS to be disabled. Not a big deal, but I'd like to get the car to 100% functional.
I've been trying to build a tune based on an 04 GT base OS, with 04 GTP Engine tables, and 04 CompG Trans tables. I thought I had it right, TCS working properly, car was running perfect. After about 3 miles of easy driving (Sub 40mph, low load) I got into the throttle a bit. At around 50mph it felt like the trans shifted to neutral, then the engine stalled. After I coasted to a stop, the engine would crank, sputter, but wouldn't start. I waited 2 mins, and it started and ran just fine. I drove a couple more miles, and it ran / shifted great until I got over 50, under higher load, then it died again exactly the same way. I re-flashed my old code, and it drove fine for 50+ miles. I tried the new cal again, and it did the exact same thing after a few miles.
Any ideas? I've never heard of this issue before, and my setup is basically a Top Swap with 3.29 gears.
The new Cal I'm trying to use is an 04 GT base tune, with every table (Accessible from TinyTuner) from my current perfectly running tune copied over.
Thanks!
