We are probably misunderstanding eachother. It will also idle bad if too rich, it'll be blubbery. Lean and it sounds like it has huge cams and will stall easily.

Have nobody done this? Should I simply add 30% to the scaling of pump?
So 696 for pump -> 696*0.7= 487 for E85

Found this page that lists latency values for a bunch of different injectors. Don't know how accurate the values are, but could be a good starting point.

The car was an Evo 9 with all the bolt-ons and HKS cams. Trims maxed out at -4 for the mid and +2.6 for the low.

Treat them as a starting point only. I have noticed that PTE injectors are harder to scale than the Densos and RCs that I have scaled.

I used this today when I installed my PTE 880's..Works like a charm and almost dead on from the start.
mid +5
low -3
I got them down to -1 +3 now..Runs like stock and starts right up!
THANK YOU NJ1266!

Threw in my pte780's and used the scaling 696 and values in post # 136 and have great idle and drivability. I'll have to log some to find out if it needs to be tweeked some, but a great thread overall! Thanks to all!

FINALLY MY FUEL TRIMS CHANGED!!!!!!

In evoscan v2.4 I'm getting -1.8 (stayed there for 3minutes) and then after a while it went to -3.4 and stayed there for over 4 minutes at which point i concluded the log.

I logged at idle for just over 15 minutes. Are these trims for LTFT-lo ok?
