I tuned my car on the dyno awhile back. Its still running rich. I decided to set my wot for 10% since i tuned for wot and my narrow is at 8%. Whats the downside to having the wot map being ran all the time and should i just set it back to 10% for narrow and 60% for wide?

 

anyone?

 

got into the same problem like u, somehow it keep runnin rich, so i end up gettin the s100 instead and use the vafc for rpm look, lol

Take the car to a tuner who knows what they are doing

 

if you read right the car is tuned already but for wot and not narrow. your post doesn't help or isn't in any way useful at all but thanks.

 

VAFC units only modify the MAP sensor signal. Therefore, they only effect the AFR at WOT. Sure, it will temporarily affect the AFR at partial throttle after a change until the ECU relearns the stoichiometry from the O2 sensor.
