MAF running 200+g/s

[r8byb]

Did a log on my car the other day, superCupra did it off hear for me, think we were in 3rd and Maf hit 200g/s +, car runs fine though as i unplugged MAF and still did the same problem im having, just wandering why its running that high, on stage 2 Ko3

Cheers Rob.

dodgy MAF more than likely, try someone elses in your car to make sure

 

[r8byb]

You reckon, i unplugged it and it felt slower

 

[truCido]

well yeah because default readings wont be as high as your MAF's producing

 

[r8byb]

I see, well the only problem im having is when engine under alot of load a slight brrr brrr noise but a guy over my way had the same problem and reckons it was spark plug gapping. and the fact i unplugged my MAF and it still did it shows it cant be that ?

 

[truCido]

you were only asking about 200+ g/s on the MAF nothing else

The spark plug gapping could be causing it but I guess the only way you'll know is to go buy a gapping tool from halfords and sort it out...5 min job!

I'd honestly try another MAF if you can borrow someone elses known to be working and do some logging on that

 

[r8byb]

Ok, just wandering what the problem is ? i thought the more G/s the better . lol

 

[truCido]

up until a certain point yes...then it starts to overfuel the car, which means its running rich

 

[r8byb]

ironically it did come up with a code running rich, but ive been told its my 4.0 bar fpr.

 

[truCido]

dont quite a few people run a 4 bar fpr without running rich on revo stage 2?

 

[r8byb]

dont know buddy, it was intermitent fault, cleared it and my mate did vag com last night and the car had been doing its little boost fit it some times has lol that brrr noise, and the only fault that came up was MAF cause i had unplugged it.

200g/s on k03....whoosh!


what sort of boost does it produce?

 

[r8byb]

24 - 26 psi, could it break ? lol

 

[truCido]

woah that is pushing it slightly!! lol

 

[r8byb]

its full stage 2 like everything to do it properly, and revo said it would be alright lol, getting a ko3s in a month or 2 when i find one anyway lol.

24 - 26 psi, could it break ? lol

blimey thats alot of boost for a k03!

 

[Beaker™]

What boost settings you on? You should be seeing 22-23psi IIRC?

 

[r8byb]

gauge might be overreading then ?

Yes, post up some logs.

 

[r8byb]

Dont have vag com im affraid was a guy off here that did the logs, then someone else who i hardly ever see. it pulls very well apart from the problem which is ment to be plugs.
