I have a vafc in my 91 hatch car is still obd0 and i have 310's but everytime i lower at 1000 rpm the fuel enough shouldnt the car like almost die. It doesnt seem to be adjusting fuel. Does anyone know what could be wrong the rpm works and vtec works. Also the throttle postion reads backwards it reads 100% at ideal and when i stomp on it goes to 0.

Please help

 

ttt

 

did you wire it correctly? and how much % are you lowering the fuel output?

 

i can raise it up to 50+ or - and it doesnt change ideal at all. thats why i think its not altering fuel. Does anyone have a diagram i can follow for obd0 car.

the manual is your friend.

the last part about the throttle is because you didnt follow the directions in the manual. you did the opposite of what you should have.

 

you're initial settings are fucked.

you want it to be 4cylinder with increasing throttle, so make the little arrow piont /^ that way. arrow going toward the top right.

 

it is set that way im going to probably soder all the wires together and see if that works

 

but shouldnt it kill the car or make it idle different if i take too much fuel out at idle

if all of your wiring is correct, then yes.

 

ok i got it to work but it works at wide it pulls fuel out at idle and at narrow it pulls at full throttle

 

you can set it at diff RPMs incase u set it all the same
