2012 ZR1 Reduced Engine Power

[Fastlane]

Hey folks- first time posting..Have a 2012 ZR1 with pulley and exhaust, efilive tune. It goes into reduced engine power mode only in 1st gear when it sees tire spin. Does this with or without traction control. I have tried turning off throttle control in the tcs settings and raising torque limit. Thank you for any help...

Post the ECM and TCM tunes plus a log of it doing it, then we can take a look and see whats going on.

Attached is the file. Pops a dtc 0641 code "5 volt reference 1 circuit" every time. Thank you for any help...
Will post a log when I can...

Make sure you have moved ETC air limits up and also raise the boost limits for supercharged.

does it throw any code?

5V ref circuit, that's nothing to do with the tune. The ECM is detecting a problem with the 5V feeds to the sensors, check you haven't pinched a wire when you were messing with the engine.

No wires pinched. Still looking. Thank you for the help...

Could not read file could anyone else, it looks like the code is related to circuit exceeding its 5 volts feeding back to the ecm. Something should be exceeding the 5 volts on adatalog it might take a while to find it. Hope this helps if not re post log file and or tune file

Hi David/etm,

To read that file you need V7 build 205 and V8 build 195 (which includes firmware 2.07.27).
