GTIWRX83 · 08-10-2004, 08:03 PM

i just got my modded stock injectors in today. I dont have an obd scan tool because they cost too much! Can someone post their zero column fuel trims so i can just have something to work with until i get the scanner??

^^^ Buahahahaha Seriously if you are using injector scaling they should be pretty dang close to 0 in the 0% column.

Scale them to 860, reset the stock ECU.

Knocking? In the 0% col? That's just about impossible. It's probably misfiring from a rich or lean condition. If it's rich, you may well have fouled your plugs.

In the days before injector scaling on UTECS (which you should probably use), people had some luck running -14 to -16 in the 0% col. Check the modded stock injector threads for more details.

Make sure "open loop" fueling is "on". Set your stock size to 550 (txs stage 4 maps are based on pinks) scale to 810. Go +3,+2,+1 progressively in you 0% column until approx. 4500rpms, and keep boost down until fueling is better. That will give you a good start.
