Having a bit of a time nailing down a throttle code issue im having
Setup is as follows
2018 6.2 l86 8l90,motor has forged pistons and rods,BTR stage 2 blower cam,Whipple 2.9 blower
Stock heads
its swapped into a older chevy
I can get idle somewhat ok,throttle is super touchy but randomly it will throw code p2138 and the throttle will stop responding
I have the MAF somewhat dialed in and have started using ltft/stft to start on getting the VVE straight before throwing a wideband on.Again trying to get to the i can throw it on the street and drive phase of things.I have a decent amount of exprience with Gen3 and gen 4 but this Pr ratio gen 5 is a new planet to be on.
Any advice,Things i should look for,Any histogram setups that can help dial in the VVE and Virtual tq?
Or where can i be pointed to do research on to get to the next step would be appreciated
Thanks in advance
