Helping a friend on his 70 c10 L83 swap. It has a BTR stage 2 truck cam with 4 deg limiter. Using a PSI wire harness. Engine, ecu, and peddle out of a 2015 Tahoe.
The biggest issue is getting the idle RPM to my commanded RPM. No matter what i adjust it stays around 1100 rpm or so. what am I missing?
attaching log and tune.
One thing I see is the peddle TQ at idle is -41 and stays there with every tune.
Thanks for any help
