Need help with High AFRs
Sup guys so I need some help. No matter what I do I cant get my afrs under 12.5-13 around 3500-4500 range and cant figure out why. My fuel map is maxed at 7.4 in that area and my maf scaling is max there too. I am only hitting a max IDC of 69% so I cant be running out of injector any ideas??
What load are you hitting at this area, it is very possible that you are still in closed loop, which is why you aren't getting any results changing the AFR table. Take a look at the open loop load tables to see when the map actually changes to open loop.

I am hitting a high of about 152 for load, I have my fuel and timing maps scaled accordingly. I even tried adjusting the lower loads just incase something was amiss in my evoscan ecuload with no change. I am going into open loop just fine, I have 440 injectors scaled at 390 with trims in check. The fuel filter is my guess too on this. I reused my stock filter on the bottom of my walbro it was plenty clean but do you think maybe its still restrictive? but its just wierd I can post my tables for you guys to look at if you like

Ya this I my thoughts too, everything above and below this rpm range is just fine right about 11.5. Also from 2000-3000 I am having to put my fuel map at around 14 to get it to hit 12.5-12 for spool up
hmmm... im still really new to the ECUflash thing, but i feel that i grasp the concept qiute well. Anyway i think its more of a mechanical error more than a tuning error. You try putting different injectors in?

No I am going to try changing the fuel strainer on the bottom of the fuel pump. Side note how do I attach my rom file here so you guys can check it out? I tried doing the attachments and it says invalid file?
