So after installing my S-AFC into my 86 GXL, i noticed that after about 50% throttle, the S-AFC reads that it is at 100%

Is this just a function of the s4 TPS that it only has the narrow range sensor, or can this be corrected? I'm used to s5's.....

 

i have a 88t2 and mines the same way. from what i've read and understand you are correct just the narrowband tps

 

Cool, thanks for the reply. just out of curiosity, what do you have your throttle point set at to help alleviate this situation?
