OSF2004 Posted October 24, 2022 Report Share Posted October 24, 2022 Dear Sir I'm using G4x civic 92 plug in. I setup for direct ignition. The engine run, but limp. Ignition no4 no spark. Coil and wiring is fine. my question is, can i alter or change the pinout for ign4 to another pin ? There is a little dent on ecu cover. Im affraid that make a short circuit. The engine fine with the distributor. Best Regards William Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 24, 2022 Report Share Posted October 24, 2022 You need to use Ign 4 if you want to use direct spark You could do wasted spark with Ign 1 & 2. Have you changed spark edge to falling? Does Ign 4 work in test mode? With # 4 coil unplugged, what is the voltage on Ign 4 pin? Quote Link to comment Share on other sites More sharing options...
OSF2004 Posted October 24, 2022 Author Report Share Posted October 24, 2022 Yes, i did change to falling. In order to test the ign 4. I have to turn off the ignition mode first right? And the "aux ignition #4 test icon" will appear. And we test with pwm ? And look for spark at the coil ? I will cek the volt in ign4. What is the reading if the system normal ?

I would expect voltage to be 0V. Quote Link to comment Share on other sites More sharing options...
OSF2004 Posted October 26, 2022 Author Report Share Posted October 26, 2022 I just test the ign1, ign2, ign3, there is a spark. But ign4 no spark. I test it with ign test. The volt at ign 1,2,3 is 10.4mV The volt at ign 4 quite high 240mV. Is it because of the short circuit ? My other option is using waste spark. Do u have any recomendation what ignition coil do u prefer ? And please tell me the wiring diagram for the coil and link setup. Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 26, 2022 Report Share Posted October 26, 2022 Sounds like Ign 4 is possibly damaged. You can use the same COP coils in wasted spark, just wire them in pairs. Quote Link to comment Share on other sites More sharing options...
OSF2004 Posted October 27, 2022 Author Report Share Posted October 27, 2022 Ok, i will use the waste spark. please help me with the wiring setup. I just need to wire ign 1 & Ign 2 Ign 1 i will pararel to ignition coil 1 & ignition coil 4 right ? And ign 2 pararel to ignition coil 2 & ignition coil 3 right ? Anything i have to setup at the link software? Thank U Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 27, 2022 Report Share Posted October 27, 2022 Correct. And set the ignition mode to wasted spark. Quote Link to comment Share on other sites More sharing options...
