Edit, some background on the engine .
1.8 vauxhall Nova z18xe running dta s40 with individual throttle bodies, basic sensor set up and I have a wide band fitted
I'm having some issues getting the car to a drivable state,
It starts and idle okish but when revved it wont go past 3500rpm its like it hit a limiter and misfires, I cant get around it by half throttling or anything.
If you could have a look at my base map and give some suggestions on any changes i can make would be grateful.
This is a fresh build and has never run properly
On a side note I've changed coil pack and plugs and I'm going to replace the ignition leads as well to rules these out, any help is welcome.
Cheers Nick

Re: Car wont rev (map problem)
Is the Crank wired correctly?
Sometimes an engine will run but have like a false limiter
On a Vauxhall crank sensor the pin outs are :-
Pin 1 - signal
Pin 2 - sensor ground
Pin 3 the shield.
It's worth a check a mistake could have happened.

Re: Car wont rev (map problem)
It's the crank sensor on that engine. If you measure the resistance, it will be over 2 kOhms.
Change it for one from one of the other engines.

Re: Car wont rev (map problem)
To be fair I did have this set up running last year albeit with an engine that had issues that I've swapped out. This is a new untested crank sensor. I probably have a spare somewhere. I'll try that and see how I get on.

Re: Car wont rev (map problem)
Crank sensor changed and it now revs freely, I say freely, it still needs to be mapped but its loads better then it was.
Thanks for the help guys.
