What's up party people!? New to the tuning game and it's starting off about as expected... can't get my car to idle
-2g gsx running ecmlinkv3
-1g swap, plug order switched
-non 95/96 CAS checked
-3" gm maft set to aux4 base2, everything else zeroed out
-base maf type set to stock in link
-650cc fic injectors: global fuel = -31%, global deadtime = 210 microseconds
-stock 2g map loaded, all comps zeroed
-base fp set to 42.5 when car was running
Car will idle very rough and then die eventually. Af reading lean off the charts on aem wideband, but does not idle smooth enough to trust any reading. Car is mechanically sound (boost/vacuum leaks, compression, fp, spark all good) Help? Thanks in advance, can't wait to cruise again!
*UPDATE*
Okay, so I got the car to idle... something is definitely wrong with my settings. Here's what I did to get the car to idle at about 15.5 afr:
-MAFT idle setting turned all the way up to 8
-global fuel up to -25% and deadtime up to 710 microseconds
So basically, had to dump fuel in. FP reading at 38 psi at idle. Will check base pressure again with sunlight.
Then, to get the airflow grams/rev to ~2.5 I had to turn MAFcomp way down to -24%...
I'm thinking there's something inherently wrong with something fundamental in the setup. Any ideas?
