Don't know if it matters, but for MY06+ F22c as opposed to MY04-MY05, the cam sensors and crank sensors are different.

i dont think the cam sensors are the problem it is definately something to do with at the crank.

it is an 07 block soo...

its so wierd though because it drive perfect until 8 grand?

and ecu reports no mechanical problems. will an ap2 ecu fix my problem

trust me there IS a difference i have seen both blue prints of an 03 and 07

if i had a scanner i would post it up

MY06+ crank sensors are different...so naturally they will not read correctly for your ap1 ecu...or even an MY04-05 ecu.

yes you are correct. but the 07+ has changed slightly. but u were right.

so yes it seems that i need to change to an ap2 ecu.

or possibly an AEM ems but i should probable try the ap2 ecu first to see if that fixes it

the 07 crank sensor wheel i believe has more sensor fingers on the wheel. (i bought the kpro conversion) at 8000 rpm its probably giving off way too many pulses or signals and thats why its in limp. also if you are continuing to use the 07 ap2 valve cover you had then the sensors in there are different also.
the most economical approach would be to buy the ap1 crank sensor wheel and change it. if you are using the valve cover from your 07 head then just slap on the valve cover from your 03
and you can keep your ap1 ecu so you can rev to 9

thanks your explanation helps alot.

and i am using my 03 head and valve coer so that problem is taken care of. as for the crank wheel yes i did actually notice a difference when we were assembling the engine.

instead of buying a 03 crank wheel what if i just bought an 07 crank sensor so it would be compatible with the crank wheel. would that be cheaper than buying the actualy wheel and would that work? and i could still keep my 03 ecu?

no you need to change the wheel and use an ap1 crank sensor. only then can you use the 03 ecu or any ecu really. i think even with an aem the car would run funny.
