Hi everyone
I have a na '93 240 with LH 2.4
I fitted the Buchka wasted spark board some time ago which has worked without any problems.
I have made other mods - moving the battery & washer bottle to the rear butt cheek, TLAO chips, turbo ECU 's, larger injectors & larger AMM / Tb, all in preparation for going plusT.
Everything has been working well and the time has finally come to fit the turbo and tidy the wiring from having lost the coil & moved the battery etc.
I disconnected the plug from the original ignition module (bosch MTR 0227 100124) when I lifted the engine to remove the sump pan. I did not reconnect it when I started the engine again and it ran ok. As the car ran without the old module being connected I assumed the wire to it could be done away with. The plug to the module contained two wires which had come from the removed coil, a black wire and a shielded wire, the shielding being connected separately. I started the car to make sure it still ran and with the engine off I cut the remaining two wires. When I tried the car immediately afterwards it didn't want to start & ran badly. It would not start at all on further attempts. I checked for continuity between the wires on the bit I had cut off in case they were joined at the plug somehow, but nothing. I joined the wires back together and the car started! I can't work out how joining on an extra 18 inches of wire can make a difference. There doesn't seem to be anything in the plug itself either.
Can anyone explain what's going on?
Has anyone else who has added wasted spark had this problem or similar?
