Right, swapped my super 8 for a level 8 ecu.

Removed all the extra injector/boost pot sub looms from my wiring loom.

Now if i plug the level 8 in and run it the ISCV is always flat out, the car idles at around 1700rpm. If i put the super 8 and greens back in the car idles fine and the ISCV works perfectly.

That leads me to think 2 things - either the wiring loom has been altered for the super 8 or the L8 is goosed

Has anyone gone back to a level 8 and had these problems?

Is there anyone who can run an L8 through diagnostics to check everything is ok with it?
