F20 M135i Pure Stage2 Fuel-IT Port Injection + JB4 tune DYNO time
Found some time to get to the dyno this morning. Had to test Port Injection. I was running 45% E100 mixed with 55% 98 fuel. Meth was disabled. In the last run I enabled it but power was the same. I Ran map 3 30 adder, 50 adder, 75 adder. And next 2 times custom map6. Once with PI only and once with PI and meth.
For reference here is a comparison from between
- E20 mix with CM5/CM7 dual nozzle meth last year when I just had the turbo (running 23 psi from 5500 to 6500 - lack of fuel midrange prevented more boost in lower rpm)
- TBI E35 mix with CM7 single nozzle meth last year in August (don't mind the midrange as we were testing some flashes that didnt work and in the end I just did a quick run jb4 only stock flash but I did not finetune midrange) (running 27 psi at 4500 taper to 24 psi at 6500)
- Today PI E45 mix no meth (running 24 psi at 5k rpm taper to 23 psi at 6500)
I know it's not dynojet but with current setup I do low 7 60-130 on flat surface. I will try to get a high 6F21 M140i - 100-200: 5.15 60-130: 5.94
