christ - you two type like a pair of illiterates

anyway.

you're reading way too much air, so it can't be scaled right.

I'm wondering if you haven't actually got a stage3 ECU for the components you're using...

well is it all mapped 4 what u got on the car? it should deal with ur upgrades i think but bassicly i think they put a mathmaticle equation into the maf so it can work out airflow etc? if that ain't right it sends it into limp all da time as i've seen with my mate ko4 done with a jabba 3inch maf. Think we now are using an audi a8 4.2vs and r32 throttle body which we found in the yard. gona have a look through ur data see what i can see.

You probably need to take it to CC HQ, unless you can suck the code out, decrypt it & understand it

just spoke to jbs and they said that the maf reading isnt accurate once you run a different maf to what the car is ment to run...how true that is i dont know!?

he doesnt think there is a map problem as he remebers it being mapped and said it was great when they had it so it isnt a map problem!

gonna try another fuel pump...

Mike...you free on nite thank you please? beer money involved:)

just a dumb ass question here im getting a tip for my 2871r and was wondering there are 2 outlets on mine one 50mm and the other 70-75 or so. For a tip i presume i'd need to get one to fit the 70-75mm size not the smaller one?

Its not the pump hooch.

The pump is supplying the fuel required i reckon, yours is even lean on idle running 18's when it should around 14.7.

I still think its air leak or maf related. Wish you were close, then i could look at it, but its near impossible to diagnose like this. DOH.

I'm sorry but I really don't wanna mess with the IHI.. its running so well...Fuel pumps etc are beyond my understanding, and I dont want to risk it...

Sorry mate, I hope you get the car sorted......

yeah, but it will read 'correctly' if it's mapped accordingly

as you say something's not right. and it's best to trailer it up to JBS and get them to look over it - but that's like writing a blank cheque as it could take ages to go over everything
