I'm having a difficult time trying to understand this SR20DET. Everytime i start my car, i think it's burning too RICH..!! Like, a lot of smoke, lot's of them. I dont know what it is. I recently bought a fuel pressure regulator, and i still dont know what it is..?? Do i need to run a Stand Alone Unit, or do i need an AIC Controller..?? Any help will definitly help..!!

The MODs on the car has: 550cc Sard Injectors, Walbaro 255LPH fuel pump, Stage II Exedy clutch, Front mount intercooler, Aftermarket Tubular exhaust manifold, Full Cat-Back 3", Fuel Pressure regulator, upgraded fuel pump. (300zx Twin Turbo). Apexi Suction Kit, with a Z32 MAF.

The car would BOGG up until a little past 3500RPM, after that, it get's very powerful, and it's climbing up smoothly. I don't know what's wrong with it? Do i need a Stand alone, or an AIC?? Thank you soo much for you help!!

What engine managment are you even running?

If you're on the stock ECU, than the 550 injectors and Z32 maf aren't even working properly....

You don't need standalone...a Jim Wolf or Enthalpy ECU will work just fine.

Do you know how much it'll cost just for them to Chip it for me? You have any information on those? Thanks for the help!

JIM WOLF TECHNOLOGY, INC. / NISSAN PERFORMANCE / NISSAN RACING /INFINITI PERFORMANCE

Racing Service Enthalpy

I prefer JWT....you're looking at between 500-600 bucks

Check online at www.sr20forum.com, Zilvia.net Homepage, and similar 240 sites for used ones...they never go bad, and if you do get one, just ship it to them, and it's 100 bucks to reflash it for your mods.
