LT1 6.2l crate engine rev when put in gear

[wasonce]

I just put in a new LT1 crate with my existing 6l80. When I put the truck into reverse or drive with my foot on the brake as an example the rpm start increasing without accelerator pedal input. If I put the truck back into park rpm will return to idle. I noticed in the log that I get a predicated engine torque of rpm limit, followed by a fuel cut type tqRed as I put it back in park. Any thoughts on what to start looking at, Tune is pretty stock.

Just a thought have you considered using a stock Camaro or corvette file for reference to copy all the idle settings? I looked at your file and it's very different from a stock LT1 file with all the idle settings. Also check out the driver demand tables.
