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.

Yes

I'm not downloading what is probably a worthless VCDS file to guess wtf he's running.

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.

Dont fix hardware problems by changing maps around.

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.

Make a log in 3 gear with ME7 logger

Check fpr vac line
And fuel pressure @wot

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.

Scrap that I have done a throttle valve adaption and now the idle trim is good,  just any more than 50% throttle and in at - 14 and climbing

Did you fix TVUB?

injectors were scaled in and been working perfectly for 7-8 months
this problem just arose randomly
the only thing that is different that i can think of is that i blanked the breather pipe on the intake hose and put a breather filter on the breather system. but cant remember if it ran ok before or after that.

If that is the case, literally the last thing you want to do to fix the problem is by changing ECU map values around.

yh i have realised that.
i will put the breather back to stock and smoke test it tomorrow at work and see what happens.

originally i thought it was something i had changed on the map but i switched out the ecu for my backup one and still the same so it has to be a mechanical problem.

So...  I changed the breather back and carried out a smoke test, but getting a lot of smoke out the dipstick tube coming back through the breather system.
Is the breather valve thing that looks kinda like a dv meant to be a one way valve? If so mine ain't working.
