I don't post here often but this has me completely confused.
ID1000 injectors
the car is running an LSJ with a TVS blower with a 2.7" pulley.
It's run by a 2004 cavalier PCM. It uses TPS vs RPM for main fueling
I'm using a 1 bar MAP sensor for spark and idle fueling
the PCM has limited parameters, and the only input for injector information is the 'injector constant'.
I scaled using my old constant for 60# injectors and the car refuses to run and idle.
my injector constant history
stock constant for 19# : 0.17800
constant for 440cc: 0.10215
constant for 60#: 0.07151
constant for ID1000: 0.0455 (this one does not/ barely runs. it is not driveable)
as the injectors get bigger the constant gets smaller, so that much makes sense... but I'm getting extremely lean AFR readings when I do manage to get it to idle (18:1)
I bumped up my idle tables 30 percent and the car will idle, but any throttle input stalls it out.
I feel like my trouble is centered around the constant. It HAS to be wrong...
