ok, so i just bought my first gsx upgrading from a 420a talon. the gsx came with apexi afc neo and when i got it it was turned off basically ( atleast i think, it said correct off in the a/f map) and was hitting fuel cut around 4k. turned correct on and then no fuel cut, but running rich. theres numbers going across like -19 all the way from 1k rpms on the map all the way to 6k and then goes to -20. im pretty sure its tuned wrong because the previous owner messed with it and had no idea what he was doing. i know the car has a 225 walbro fuel pump but not sure on the injector size but i know there bigger and i believe they are 550. trouble is i dont have a wide band only a narrow. just wondering roughly what my base settings should be through out the low and high throttle rpm bands untill i get this thing to buschur with a wide band and a dyno. thanks..

btw running 18psi on stock turbo
 
thanks for the link, gives me a general idea of what i need to be running so im not too rich. and yea im hoping to get a widenad here soon but untill then i might just have buschur use the one they plug into the exhaust. really im hoping to be able to afford dsm link soon.
 
Before you can get any real idea of where to set the AFC you need to know what mods your car actually has. Do you have an AFPR to go with the 255? Ask the previous owner which injector are in the car. With some basic info we can get you in the ball-park. Do you even have a logger?
 
Okay, I know there 550 fuel injectors and no there's no adjustable pressure regulator. And I don't have a logger yet. I'm new to tuning, but not to dsms. I got a lot of experience with the cars but am just starting to get into tuning.

And I mean, its the stock turbo and its boosting 18psi fine...
 
I have a 97 Talon that i would like to know what setup i would have to use for my apexi neo. I bought the car from a guy and it had the apexi afc neo in it but it reset on me. I have a B4152w in it and need the right tuning settings so my car can be running good again.
