Fuelling problems!
Discussion
A few weeks ago i put the chim on a rolling road, Triton Motorsport in Hurn Airport, to see what it had in the power dept. The results were mixed, 206BHP at the flywheel and 265lbft, which is good for torque but not too good for bhp.
What it did show was that at 4k rpm it was dumping fuel which in turn reduced the power output as it peaked at 3.5K to 4K rpm. The owner said it could be the AFM, Fuel regulator or the ECU Coolant temp sensor, i replaced the latter with a new one a few days later.
Since then i have run the car with an air/fuel probe and it is still dumping fuel as before, i've checked the AFM, no apparent faults and i would of thought that the fuel regulator would make it leaner not richer if it was packing up?
Does anyone on here have any ideas?
Many thanks
