Procharged C7 closes throttle @ WOT !!! need help

[GR8GAME]

Whatever became of this?

I am having the same issue on a dyno with a 2014 Corvette Z51 Auto.
The throttle closes to 58% during a WOT run.

A&A kit. 8 pounds of boost. ZR1 MAP sensor.

Try this: in B5201 set Park and Neutral to 6600 rpm.

Also in B5212 set the 4000 values to 6600 just in case.


Are you getting any DTC's...?

Was this car previously NA and now it has an SC...?

Also look at C1801, C1802, C1803, C1804.

I have not been getting any DTC'S with the car.

Yes, it was an N/A car! The customer installed an A&A kit himself.

I will play with those tables this morning and see what it does.

Does he have the right MAP sensor...?

I made the adjustments and the throttle is still closing. Crazy! I've never seen this before.
I'm going to upload the trans file too. Maybe the trans is messing with the ECU on this one? (T43) Rob Anthony 2014 Vette Z51 Auto (24270599)-Base_0000.ctz
