Running too Rich... help
at 5.5psi on a stock d16z6 with a 12:1 FMU...
I'm running real rich while in boost, i.e. a little dark smoke out the tail, a/f gauge shoots into rich, horrible gas mileage.
Should i have a different FMU on there.. is 12:1 too much pressure for that boost lvl? What are some ideas to do?
Thx

Re: Running too Rich... help (Guitarzann)
I had the exact same problem you have last weekend when I completed my Drag III installation. Just remember, that is what the 12:1 FMU is designed to do keep you running SUPER rich, therefore decreasing the chances of detonation.
To correct this I would either get the 10:1 disk or get an Apexi VAFC. I chose the later and was able to turn my fuel down to the desirable level. Just make sure you keep your eye on the A/F level
