OEM SOI on these CF2 typically is 17-21º BTDC at high revs, EOI should be -2<>4º ATDC, with +10% inj slightly more.

Don't worry about your turbo, it's a great mechanical VNT turbo, easier to tune without boost spikes and other issues, good electrically VNT tuning is endless work.

great engine,i do i file for i friend with the same engine with 1,5 bar of boost and 77mm3 of fuel and the car feels very strong :thumbup:

I'am struggling again, made remap versions which is near perfect till car reaches ~190km/h (6th gear 3.5k rpm), at that speed car drops acceleration and barely goes beyond. Remap pushes IQ limit from 55 stock to 70mg, which is very noticible while driving and obd logs confirm that.
Engine runs without any strugles at 190 km/h speed so i don't think that it's engine problem that it drops acceleration. On youtube i have seen that 2.4jtd engines can go 4.5-5k rpm at 6th gear no problem. Maybe someone could look at my remap project and guidance me like their Padawan :)

I attach project, just remove fake .bin extension, i added it because .ols extension is not allowed (wtf?).

So you yourself on the maps (TL, ...) reduce the fuel supply after 3500 rpm., It is unclear. And what project to watch?
The majority of the problem is in the air mass meter. Walk away from it, and switch to the MAP sensor.

Previously i attached winols project which i use for modifying ecu maps. I atached project because there are more changes than torgue limiter modification. The problem is that IQ is raised from 55->70 within 2-4.5k range, this IQ increase is felt every time i drop a hammer on floor except with 6th gear from 3.5k rpm acceletation unexpectadly drops. I will try switch from MAF to MAP.

ive got tge same problem in my car and i cant find solution,car pulls very strong to 200km/h and then nothing,and ive got a 2256 and 110mm3 @ 2 bar boost at 4000rpm,but on sixth gear vant pass 3600revs

You should do logs with:

- rpm
- inj mm3
- boost desired + actual
- air temp
- fuel temp
- rail desired + actual

if something is wrong you will see it.

i do a hundred logs and no see any symptom of failure
any miss torque limiter??
becuase speed limiter is 299 in ori file

Without seeing log I can't say anything.

Over 180-200km/h aero resistance is big, you need so many hp from that speed. It could be normal or any limiter.

Here's acceleration 0-100 starting with second gear, raining conditions so i waited a bit before flooring second gear to prevent slipping. Today (after making video) i increased rail pressure from 1350 to 1400 and advanced soi by 1.5° in high IQ range, havent felt difference.
