Running rich

[moll88]

Hello everyone a question for you, I have cpe nano, rpcm tip, ATP dp, vibrant dp back exhaust , ap stage 2 93 map , forge gen 1 bpv blue spring no shims, now your up to date on the mods at wot I run really rich about 10.0 afr is ther e any way to lean it out a bit ? Also the end of the month I'll have my fmic on and will that help or no ?

Well what I hear is that a FMIC does helps AFR. So if you don't mind waiting, wait after install of the FMIC and see what happens. But since you have a DP maybe it's time for a pro tune or learn to use ATR and at least calibrate your MAF.

I'm surprise no one is mentioning this but running rich isn't really a bad thing. Actually, running rich is safe for you car. You just won't be able to make good power. Stock tune this car AFR will drop in the 9s. I'm just saying don't worry to much about it , but would still get a tune to get the most power out of your engine.

So wait...I thought having a low number (9s-10s) was a bad thing??? So if I'm on the throttle, not necessarily WOT, but 60-75% and my AFR is say 9-11...that means I'm running rich and could potentially tune more power?

~11:5:1 is good for wot. 60-75% should be ~mid 12s. the lower the number the richer the mix.

If you see 9-11 at part throttle then you have a problem. If AFR tampers down in the 9-10 at WOT then your fine since that's what you'll see on a stock tune.

The OP should really go for a pro-tune or learn to use ATR because no OTS map will really help you from now on, as each car is different and you have a lot of mods.

Don't want to scare you but that's how a lot of cars go boom. OTS maps + lots of mods.
