Hi, my car's in bad need of a rolling road tune, does anyone know of a good one in the North West/North Wales area?
Cheers, Nik

 

IIRC prosport at stockport have 1

 

Prosport have a very good RR.

But why do you say it needs a RR tune? I asume you mean the cosworth? If so there is nothing to tune as such, everything is ECU controlled. Whats wrong with the car?

 

Hi John,
yes, the cossie, I've not had it long but it doesn't run smooth, at about 4500rpm it misses a bit & seems to be overfuelling.

Also every now & again it'll just die when you give it throttle & start misfiring & popping & want to stall whilst throwing out soot from the exhaust, if you turn the ignition off then restart it, it's ok then..... until it does it again.

Any help would be much appreciated! Nik

 

I suggest you go see a good cosworth specialist, you dont need a RR to diagnose most problems on a cossie. Sounds to me like you have a sensor down.

The guys at Castle Performance know what they are doing, they are in Newcastle, near stoke on trent. http://www.castleperformance.com/ I used these for my cossie and cossie powered westfield, a good bunch of people.
