I have recently installed the PLX M300 wideband setup... for those of you who are familiar with this setup, it starts out reading 14.7 , and after approx 20-30 seconds, it starts increasing 16...17....18.."LEAN". To avoid any possible damage, I shut the car off. I find it highly unlikely my AFR is reaching those heights within the combustion chamber. I have read on other forums that at first the engine uses the air pump to compensate for heavier emissions. Does this apply to the 5.0? I have an 88 with 89 Mass Air system...
wideband is feeding a narrowband signal to ECU at pin 43 ( I replaced my left bank NB sensor). Any tips as to what to expect? Read sig for any mods - I have posted before on proper tuning procedures, however now I am leaning twords a tweecer.
as a side note: 20 HG vac constant, clean MAF, everything is calibrated to eachother, FP @ idle 45psi. Any other pointers?
I was going to replace my narrowband on the right bank anyways since I do not know its age, and I do not have a CEL to let me know if its junk.
Ive also read I need to install a 20ohm resistor in series with the heater circuit...is this the wire leading from the wideband controller to the ECU at pin 43???
THANKS
