I run a P8 (with pectel board, coilpack, als etc) and i'm having issues with the engine on anything but idle. The engine is a fresh build that came straight from Field Motorsport's dyno. I will be ringing first thing tomorrow morning - but thought someone might have a few suggestions or alternative ideas that I have not explored.

I have replaced - Air Temp Sensor, MAP Sensor, Coilpack, brand new Grey injectors, new plugs, replaced a dodgy plug on the Crank sensor. I use a Zetec Cam Phase sensor to emulate the dizzy phase sensor. This has also been replaced.

I have gapped all the sensors about 10 times, I have checked all the loom plugs over and over.

The monitor reports no problems with any sensor.

Here are some figures from the monitor:

First set of numbers are with IGNITION ON ONLY (engine not running) - Second at IDLE.

RPM 65535 - 900
BST 0.99b - 0.40b
AIR 001c - 018c
H20 018c - 020c
TPS 02 - 02 (degrees)
IGN 00.00 - 38.75 (degrees)
INJ 00.00 - 03.13
BAT 12.4v - 13.6v
COPOT +126 - +126

Now my P8 has a COPOT - I am unsure if this is normal as well as the +126 value the monitor is reporting?


Any help or ideas are welcomed.
