cars that just run off a maf dont see boost, just airflow as far as i know. but just throwing injectors in there might not work too well (dsm guys do it, but most get an afc as well)

Re:Fuel setup when going low boost turbo (around 7psi)

I have a MAF sensor in my car and have 440cc RC injectors. I would highly recommend getting an AFC to lower the voltage output of the MAF sensor. Without the AFC, my car would not idle and anything other than full throttle (close loop) was shitty. The AFC hack doesn't really apply to MAF equipped cars. The only time you would get a CEL is you have way more airflow than the MAF sensor can read with the AFC already compensating for it. At this point you could use dual MAF's so the sensors send out half of the voltage to the AFC (not necessary for 7psi

). The AFC has this feature and just takes the average of the two sensors and sends it to the ECU. Too much trouble in my opinion, it would be better just to get a standalone, or if they offer it get your ECU chipped.

hmm...does your maf have an adjustment on the bottom like a dsm one does?...you may even be able to swap out your maf for another one, but im no expert

Re:Fuel setup when going low boost turbo (around 7psi)

ok, so i'm leaning towards injectors and AFC. what's the cheapest AFC I can get that's not crappy quality? any suggestions I can look into?

Get the Apexi S-AFC, works great for me. Check the for sale section of this forum, they have great deals.

Those are too expensive for me. This should work fine for my app right?

Re:Fuel setup when going low boost turbo (around 7psi)

I'm not too familiar with that one. I know the one with 5 ***** have a **** for each RPM setting. I would really try to find one of those. I think that AFC has only one RPM setting that goes throughout the rev-range. I am pretty sure that it will work to a certain degree, just don't get injectors that are too big. If this item is used make sure you get the harness too. Good luck.

Re:Fuel setup when going low boost turbo (around 7psi)

Yea, I would preferably like to get the 5 dial one to controll different rpm range but i might settle with this. remember i'm not gonna run much boost with this. and i'm pretty confident that won't change in the future. i got enough money going into my turbo honda as it is.
