    Graham the original spark plug cables of the E30 have a resistence of 6k ohm maybe that is interfering with the ECU at high rpm. I did have the opposite problem in my BMW E21 when I swapped the original spark cables for one custom made just to find out it didn’t work without the resistors.

    What grade bolts have you used round those discs and bells please, 8.8 or 10.9's? Look like copper locking nuts, like manifold nuts too?

    ive now changed leads, but it used to work on the old ones so why the sudden change?

    not sure, but 8.8s but would be good enough, yes they are manifold nuts, i wanted a lock nut but given teh disc glow red under race conditions i didnt think nyloc was a good idea
