tweety Posted March 4, 2014 Share Posted March 4, 2014 My question is- there is a transister mounted on the coil mounting bracket. There is also a condenser nearby. There is a black and white wire from +ve side of the coil to a two pin plug see pic and the second wire a black one goes to ground. As you can see from the picture there is nothing plugged into this plug. I assume it is a plug in condenser. Can someone enlighten me about it, what effect it will have on the ECU if missing? I beleive it has more importance for the operation of the ECU than noise suppression in a radio. Also what specifications has it? As I'll try to hunt a similar condenser in Oz. Finally I do have a spare coil mount with transister and a different style of condenser plug on it. A black cylindrical type. think it might be from a later model. but I dont have the other plug part that goes to ground. Hope I can get some answers and pics to please.

ruparts Posted March 4, 2014 Share Posted March 4, 2014 hi, i know the piece on the coil bracket is necessary, and the bracket must be grounded , but i can't say about the other wires and condenser. 1 Link to comment Share on other sites More sharing options...
jono Posted March 4, 2014 Share Posted March 4, 2014 so...these spfi EA82's used similar ignition set up like 87.5 XT and mpfi including turbos, and an optical dizzy ? Link to comment Share on other sites More sharing options...
ivans imports Posted March 4, 2014 Share Posted March 4, 2014 Just for radio noise the most important thig is that the coil braket is grounded 100% They also had plugs going to nowere for Subaru test diagnostic tool to hook up and check ig circuit that's what I think you are looking at Link to comment Share on other sites More sharing options...
Gloyale Posted March 4, 2014 Share Posted March 4, 2014 There shouldn't be a condensor on the SPFI coil setup. Link to comment Share on other sites More sharing options...
tweety Posted March 5, 2014 Author Share Posted March 5, 2014 A capacitor .47 microfarad rated at 250 volts I've been told is suppose to be there to stop voltage spikes? Maybe my conversion wasnt complete etc. Link to comment Share on other sites More sharing options...

tweety Posted March 28, 2014 Author Share Posted March 28, 2014 thanks Gloyale. have taken off the sPFI system and going to put on a 38/38 weber with the SPFI manifold. back to basics. Link to comment Share on other sites More sharing options...
