Hi Guys.
MG MAESTRO 2.0 efi
I have an aftermarket ignition system ( MSD - using with nitrous oxide ) which takes is trigger/feed from the NEGATIVE WIRE from the coil. Car wont fire when I disconect this wire from the original coil. So the question is WHY NOT; I know it obviously sends a signal to the ECU to fire the car; but this is the same damn wire I need to trigger the MSD. It all works when BOTH connected, but cant really have a redudant coil sparking its guts out when there is loads of nitrous and fuel around............
HELP PLEASE; I need that wire to trigger my MSD but the standard ECU/IGNITION does not allow the car to start when I take it away and connect it to the MSD. YOU CANNOT CONNECT ANYTHING TO THE COIL APART FROM THE MSD WIRES - ask the many rolling roads who have tried and blown up their diagnostic machines !
Please guys, dont give me any low downs on pros and cons of nitrous oxide, I've been doing it for 20 years and know more about it than anyone. And no slagging off the MSD; just firing up the Maestro today its engine tone changed and screamed to its peak rpm without more than a dab on the thottle pedal. NO NITROUS, NO MSD, NO KNOWLEDGE.
Thanks
Perry
