i finally got the car runnign right ridding it of the FMU and running a afc hack and the car's drivability w/ 440's are great. just one slight problem.

currently i have the settings with 440's from 1-3000 rpms -40% and then from there i tend to lean a slight bit from 4000-5000 rpms right when i am getting into full boost. now b4 turbo i was having the same problem all motor right now i am running a ls ecu on a b20z motor. so if -40% across doesnt do that to a ls where should i set the fuel after full boost? i tried - 32% from 4000-7000 but the car still has that small leaning problem. i kno i have to adjust hi and low also which i have but still its a small leaning problem which i want to be able to fix and i always ask questions and tips on how to do fix this minor bug until i get it tuned.
my setup currentyl is a b20z w/ a revhard turbo upgraded precision sc61 turbo 7psi. i did hear b4 that since its a b20 for chipping it i would just run the map 10% richer than the ls map so should i also do the same for this settings?
any help would be appreciated. tryin to enjoy boost.

thanks

how do you know its leaning?

set it a little richer...try 30% if you say your still leaning at 32%....i dont see why tho because 32% should be sufficiant for the amount of boost you are running

 

what kinda fuel pump are you useing? and do you have a adjustable fpr? maybe your fuel pump cant supply the fuel you need.

walboro 255lhp pump what i was thinking of doing was getting rid of my B&M fpr because i did hear it fluctuates alot.
well i am going by my a/f gauge a lil bit when its in full boost it leans from that one point to another. would it be bad to richen that one spot but keep the rest of the increments @ -34-40%? would that be bad cause its tuning one spot rich and leaning it back? i would figure not but ima still new to turboes and tuning itself

gee thanks for the jinx *******

 

Nope, not a jinx, pretty much the truth - you're going by stock O2 sensor readings and using an AFC at low boost where there is considerable ignition advance taking place.

A couple hours with the search function should fix you right up. I've done two writeups on the subject, nobody pays any attention, and I'm sick of typing any more about it.

So, heads up: ka-boom
