still having probs with this car was recomended norris motorsport but when we went up he said he has banned these cars and wont work on them anymore can anybody else recomend somewher local to derby to take it too before it gets set on fire lol

 

What's the prob?

 

the car seems to miss fire or got a fuel cut when on boost and its banging threw exhaust if you try and drive threw it .normall driving seems fine checked all sensor /changed fpr/act and checked for boost leaks changed plugs/leads coilpack still the same car also smells of fuel cheers

 

How much boost, is the car chipped, what's the spec?

 

car has been chipped and running a piggyback called a unichip and t3 about 12psi boost and got a superchip in bottom of ecu thats says on chip says ofab p3 if that helps cheers

 

its also 1.8 efi block

 

It's a ZVH with a Superchip and a piggyback ecu.

Sounds a bit conflicting.

 

oranoco think he means its got a chip plugged into ecu that says chip not both superchip and chip



sounds like she overfuelling to me, get it to a rolling road mate

 

i thought that but what would be causing to overfuel m8

 

does it have a unichip fitted or superchip?

 

was running sound till this prob accured so not a new build if that makes a difference cheers

 

my mk2 fiesta turbo ran perfect one day then the overfuelled like fuck the next, didnt touch just did it, could be the chip itself, injectors leaking, feul pressure reg not opening, map senor fault, take your pick mate

 

sounds like an injector problem, have you run low on fuel or used bad fuel that might have damaged an injector?

 

changed map sensor and put new fpr on and is there an easy way to check injectors cheers

 

not ran low on fuel always plenty in above quarter on gauge m8

 

could be the chip has worked its way loose from the back of the ecu, if its worked its way loose thgen the standard ecu program is return which includes the boost limiter so once it hit 9 or so psi then the cut out occures, this might not be the problem but defo worth checking.

Hope this helps mate

 

do you mean the chip that goes to the bottom of ecu or is there another 1 inside the ecu itself cheers

 

The one that goes into the base of the ECU in the passenger footwell. Teh contacts are famous for getting mucky and giving a poor contact. Remove teh chip and clean the connections on both it and the ECU witha non abrasive cleaner.

On my FRST I made a couple of cardboard shims to go between the chip and the ECU to hold it all nicely and used elephant tape to hold the chip in place. Worked a treat for quite some time.

 

one in bottom of the ecu mate, disconect the battery, remove the chip and then make sure connections are corrosion and dust free thenrefit chip and reconect battery, other thing to try would be plug the pipe that goes inlet to fpr, if problem goes then the fuel pressure is too high and needs seting up propperly

 

Had a unichip On a mk6 escort I had, was fine for a few months then started cutting out when it got warm and wouldnt start, took ages to find out it was the chip richening fuel mixture up and fouling plugs

 

i will try these tomorow thanks for all the help on this cheers

 

i will look into the chip and see if its easy to remove the piggy back unichip m8

 

Hi mate, it just plugs into the rear of the ecu, easy to locate and check

keep us posted on how you get on, finger crossed its an easy fix

 

will come back on tomoz and let you know cheers

 

Doesnt have a vernier cam pulley does it??

 

yes it does have a vernier pulley
