Car needs to be running for a while before the missfire detection becomes enabled.

Trims on 032 look fine.

Is tha pre cat or post? Funny you should say that as my liquid gauge always reads rich even at wot doesnt go below 14 afr

Its pre-cat mate, £135 from TPS, if this is the problem of course

[krisbutler02]

Need somone to have a look ill get a video tomorrow sounds like a rally car idleing .

Was that log taken in 4th gear at WOT?

At 4.2k your making about 191HP, less than a Stage 1 K03 - however you then go on to make a full 307HP at max revs (estimated).

[krisbutler02]

Yes thats at WOT it does seem low but i havent a clue why.

Any ideas ?

[krisbutler02]

Could be due to the fluttering boost

[krisbutler02]

Here is a log from today with a bit more info

[krisbutler02]

The boost seems to be requesting low values and also fluctuating along with the maf reading fluctuating.

What could cause all these problems.

I need to take it to someone with the know how as im stumped.


This is stage 3 with all the mods you can get bar WMI so surely should be making alot more power than the calculated 307 bhp!
