i just installed my vafc and the tach in my accord seems to be off a bit from the vafc...im guessing that i should trust the vafc....but my car doesnt like to rev very well .......i peak at about 7200 and it just doesnt feel right when up that high ....
any ideas

 

the VAFC is off alittle. maybe 1000 rpms? around thre im guessing. just look at your tach and not the VAFC. the tach should be correct

 

I'd stick with the VAFC reading. Since its tapped in right at the ECU shouldnt it be more accurate?

 

I agree with 4bidden, the vafc is more direct and looks cool to

 

did you reset the ecu after you installed the vafc?

 

yes i did
and if the vafc is off on rpm then the thing is usless..it dependes on rpm to adjust fuel.....the car is an accord and the motor is prelude ...i would assume the accord tach is off

its accurate untill i get on it and then it seems to lag.....

could it mabye be that my valves are out of adjustment????mabye my cats clogged again
