On my son's 94GT, CBAZA with a J4J1 tune with mods. Idle is good, but during decel the HEGO's read in the .7-8 range, the tracer ball on the fuel open loop table shows in the top row, like it's under heavy load, but load only shows 18.
I'd think it would be like my foxbody cars where the HEGO's read on the lean side....

load isnt used for fuel, perload is but sounds like the fn035 function is jacked if it is indeed logging correctly and prldsw is set to 0

regardless fuel table isnt used on decel. In closed loop the hegos control fuel.
