wtf? your "sensor" wires from the AFC are wired by the ECU connecting to the MAP sensor wires..... thats how it adjusts the fuel... of course you'll be running 450cc injectors if those are not connected correctly stock is 240cc.. i had the same problem with my DSM 390cc injectors. rich as hell

I figgured out the map crap, yes I know I should be running rich because they are bigger, but everyone else on HMT seems to be able to lean it out enough with this set up

Just take the car to a performance shop that specializes in turbos in your area. save yourself alot of stress.

i did...I trailer it 1 1/2 hrs away to the nearest import tuner, he put it on the dyno, ran it once and said, NO way am I touching this, it isn't safe, charged me $160, and set me on my way. he was a real *****! Then he gave me a lecture on how afc hack sucks and i'm an idiot for setting my HMT up like that and told me to get a hondata and then come back...
I'm send in my injectors out to be tested and cleaned, one of them might be stuck open someone told me.

Tell Me Turbo

When you go to dynos here you sign a waiver saying that you can't hold them responsible for any damage done to your car while on or after the dyno due to any modifications they perform. I would have been really pissed too if a guy said he wouldn't work with my car after I drove it all the way down to him, and then had him lecture me on my setup, and then charge me 150 bux. People go to dynos with fmu's and a wideband for crying out loud and get better treatment then you got. Go to a different dyno where they are nice and willing to say helpful things.

that's the thing, All the dynos that are close don't work on imports only muscle cars. I live in Michigan, and Michigan sucks for imports

Tell Me Turbo

Anyways, 40 % across the board will have you very lean while in boost. You probably have an unrelated issue to the vafc settings if you are rich across the board. Yea check into the injectors, I also don't know what the deal with your car is, wether you had to do resistors or not for low impedance, so I can't help there.

yea my car got the same shity problem im lean at idle running 44% i got 450's with the s-afc now heres what it is doing idle is lean just some regular puting around town i run perfect and when i boost i go rich witch is good but im also only running the afc at low throttle it is 42% across the board. ((any higher numbers than this makes my car cut out. but the gauge is rich as hell)) till readline and high side is pushing low 30's but the throttle point is set at 89-90 i was thinking could i just put my stock injectors back in and run the afc into the positive side instead of the negative with the big ones also im running only 8 psi and i got a FPR set at 45psi 1990 integra obd0 1 wire narrowband (stock)o2 sensor auto meter a/f gauge also my spark plugs dont look bad they have a grey color to them on the tops. ? looked just like my stock plugs before i changed over witht the better plugs when i started my turbo project do you think this is a confuzing post

OK I finially got the poblem worked out. It ended up being an Injector that was stuck open. The first set were a set of Blue tops out of an 89 gallant, just too old, so I got some black tops out of a 95 talon and just tuned it today an its great. 14.7 cruising and like 11.2-12.0 afr in full out boost. FINALLY I can drive with confidence.

what are the settings on your vafc now?
