Unhappy scoobyecu missfire :o(

since fitting a scoobyecu i now have a terrible missfire

cant unfit the ecu and dont haev the resistor to put back in

BUT it only happens above 11psi

just fitted new coilpacks, MAF and Lambda
plugs have done about 10k and are PFR7Bs and look fine, gapped to 0.8mm

it is mapped for full decat
but im only half decat (still have p/d cat) will this affect it?

Have you checked the coilpacks for cracks? These tend to die after 6 or 7 years of use

I've just replaced 2 on mine, and it's much better now The ends of the old ones nearly dropped apart when I took the rubber boots off them.

I think you will find that 0.8mm plug gap is too big

close the gaps slightly.. you can just short the resistor with a piece of wire..

Fuel filter? Fuel Pump. Coil Packs. Plugs.. ign module, wouldnt suspect maf or lambda.

Where in the country are you?

Normally defects in the ignition/fuel system are highlighted with increases in boost
