Misfiring CSL

[thompson]

hi Guys

Well here is the update on my csl,

BMW have done further tests on the car, They have tried injectors because they said they found a fault with it,However the problem is still there so i aint going to pay for that i told them, They done a compression check and cylinder leakage test which came back 100% okay,
they said it is not the headgasket, They conducted a vanos test which came back 100% okay and now suspect its a ECU problem but are asking me if i have ever had it tuned/remapped (which it is-superchips),
they also said its a electrical problem rather than engine related and
need to try a ECU.
any way i decided to get the car out of there becuase it seems like
they are guessing it, today i got the map removed and it made no difference,

I had a indy give me the fault codes which are

196-C4 Misfire,Cylinder 1 with cylinder cut out
197-C5 Misfire,Cylinder 2 with cylinder cut out
198-C6 Misfire,Cylinder 3 with cylinder cut out
204-CC Misfire,Several cylinders with cylinder cut out

but he cant look at it till a week and half, So i called up Simpson Motorsport who were very helpful and stated they dont think it can be the ECU however they would need to check it, The problem is i have to wait
another week, thats nearly two weeks i have had this problem and i have
got nowhere, i meant to be taken the car to nice this weekend
and my plans, my car are totally fkd.

So now i am stuck and dont know what to do,

Potentiometer??? what is this and where?

Serious Help required.
