hi guys,

umm ive recently had a bit of trouble with my 13bt its out of a series 5 but lives under the hood of my series 3. its got a microtech mtx8 running it and lately when i hit boost i get a hesitating jerking from the motor which can be felt throughout the car its very violent. i tried cleaning up the engine bay moving CAS loom and spark trig loom away from everything but it has not resovled the issue.i have also changed the CAS to no advantage and today i couldnt even get it to start i only have spark off the leading coils (4 induvidual coils not the standard ones)but when i get a cranking rpm i get spark off the trailing. i also have a REF error which is displayed on the hand controller when doing error check but only after an initial turning over of the motor. i need help im out of ideas

cheers jacko
