I recently purchased a vehcile that had a s300 already installed the vehicle was said to be tuned on a dyno but the car was leaning out up top. I adjusted my fuel and ignition tables to have the vehicle running safely until spring when it will be dyno tuned (car will be put away for winter). My question is why do I need to add so much fuel up top to get this car to run safely.
Setup
h22 9:1 compression
iron sleeves
mitsubishi twin scroll tf07 turbo
top mount manifold
dual walbro 255 pumps (could a failing pump cause the tune to go lean up top)
precision 880cc injectors
attatched is my old map and new map and a datalog from third gear on new map

Re: Current Maps h22 turbo
It probably was not tuned properly.
Re: Current Maps h22 turbo
okay and also do you know why I need to add so much fuel up top hondata duty cyle is saying im maxing out 880cc injectors. Im currently only running 9si and when looking at others maps there not running near the amount of fuel I am up top.
Re: Current Maps h22 turbo
Check your fuel pressure and see what it is doing.

Jup, check your fuel pressure.
