i have been getting this problem where boost and power cuts at 5000rpm
did some logging and found the throttle valve is closing when still at WOT
just before, and probably the cause my stft are at -20
do i adjust krkte or do i do it in fkkvs
if fkkvs i need some help as i have no idea how much or little i adjust the numbers
i assume they are injector opening time
i have attached a log of two runs

why on earth would you use fkkvs to adjust out 20% (probaly more , you maxed it out) fueling problems?
I don't get why that is even an option in your mind, given the copious amount of information about how to tune KRKTE, TVUB, and MLHFM properly.

Also is your ECU not compatible with ME7L?
You also didn't mention
1) what car
2) what motor
3) what ecu p/n
4) what mods
5) what you have changed in your file
Not sure what you expect anyone to say.

sorry didnt think about that.
it is a golf 1.8t with 550cc bosch injectors, big turbo build, fmic, high flow pump etc.
i just wasnt sure if just adjusting krkte was correct as normal driving the trims are perfect, it just starts coming up when i get in the higher rev range.
thought if i just adjusted krkte it would then put my normal driving +20%
and using fkkvs i might be able to adjust the fueling in those areas.
im not on here to have my backside torn out, im trying to learn the best ways to fix an issue.
i have read post about using fkkvs to fix fueling issues.

FKKVS isnt used to "Fix" 20% fueling correction though.. If you get 20% stfts something is seriously wrong with the car, I'd prolly start with the hardware first, and at the very least some me7 logs and summary of adjustments made. |

Any idea what could be causing it?
I have already changed the MAF, plugs, switched to mbc, hard intake pipe incase it was collapsing, checked turbo for play, changed fpr.
Just can't seem to fix it.

Well then follow the form rules. Poa none really cares about your issues. Also when you dont post how you should or do proper research / reading before hand and ask for help wont get far. Also if you havent changed your injector dead times you'll wanna do that too |

I will get me7 logger sorted later and try get a run done tonight or tomorrow morning.
Been looking at my trims a bit more and at idle I'm getting -15 and if I give it an air leak (took vac off recirc valve) I get +15 it's like it wants a small air leak to be right.
