Coyote 3-1-1 build

[Cozmo2806]

I have a gen1 coyote swap car that currently has a stock control pack tune file. Swapping the shortblock to a gen3 shortblock due to a rod knock. Assuming the compression will rise to near 12:1, what changes would some of you recommend in the tune?

If it were me, I’d start by lowering the borderline tables by 4 deg across the board (or only run premium fuel and leave borderline alone). You could also raise the LTT tables by about 3% and lower the TTL tables also by 3%.

Yes only premium (93) will be used. Thanks for the advice, I guess we will start there.
