For some reason i cannot get my 05 vette to start in open loop. once i put it in closed loop i cant get it to start, but while its running and i turn closed loop off in the scanner i see the computer go from 14.7 commanded to 1.47 commanded and kills the motor. anyone else have this issue before? Basically I want to tune this thing in open loop, but cannot get it to run in open loop whatsoever. wont even start.
