E38-2011 Corvette Grand Sport full flash, get "service traction system" + "stability
East Coast Supercharged Grand Sport Corvette, 2011. They supplied a base tune using a map sensor from a zr1. They said it needed a full flash, therefore selected "flash tune and operating system" in newest release of V7.5
Flashes, and on restart, cranks for a long time (presumably while MAF fails), and then gives error on the dash "service stability control system" Traction control system, and on first start, "Service electrical system". On restart, no electrical system error.
Here is the tun file they supplied. They told my friend they have lots of these running around, and this was the first with with this issue. After our first attempt they sent another file with same result.
If we flash it back to "stock" with just a few changes for 60# injectors, and re -install stock map sensor, it runs and drives with no errors.
Any suggestion?
