So i installed a different ecm and converted to a heated o2 sensors a couple weekend ago.
well upon installing the ecm i imidiatly noticed my idle was at 1000 where at the old ecm had it at like 700-800.
so i hooked up a scan tool and my o2 sensor was working great it was actually switching at idle now
but my blms were at 108
soon after i ajusted my min air rate and tps
well low and behold the car was idling through the iac only haha so oviously something was deffinatly wrong with my old ecm becuase i had ajusted min air and tps when i had the old ecm in and got it to idle specs.(which happened to have the tb plates closed completally.
so any ways after ajusting min air rate and tps my blms were 115-120 rance at idle now.
so deffinatly better but still a tad rich.
does anyone here think my bosch type 3 injectors 22# could be causing it to be slightly rich(low in blm's)
or what else can i look for?
what about the 180*t stat thats installed and royal purple coolant addative im running about 180*-190* could this richen the mixture a little?
any advise, comments, and this would be helpful id like to have the car tip top for dyno day.
ohh and my 9 bolt no longer has posi lol rebuild time
thanks! _________________ 87 Camaro Z28 - Iroc-Z |
