Adamw Posted December 24, 2020 Report Share Posted December 24, 2020 You need to set the spark edge to falling for k20 coils. Quote Link to comment Share on other sites More sharing options...

I want to confirm my access to the ecu wire. Can you give me a picture? Quote Link to comment Share on other sites More sharing options...
Lim1214 Posted December 25, 2020 Author Report Share Posted December 25, 2020 I followed the wire in this picture to connect my k20 coil. There is 1 wire in my pin a20. I will change to the plug of the k20 coil. Am I doing it right? Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 25, 2020 Report Share Posted December 25, 2020 Yes your wiring is correct. Coil 1, pin A20 Coil 2, pin A21 Coil 3, pin A31 Coil 4, pin A32 Quote Link to comment Share on other sites More sharing options...

Coil 1, pin A20 Coil 2, pin A21 Coil 3, pin A31 Coil 4, pin A32 All are correct. My original a20pin has a wire. I cut it and installed the k20 wire. Is it correct? I use the original distributo。 Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 25, 2020 Report Share Posted December 25, 2020 Yes that should be fine. Have you checked timing with a timing light? Have you tried changing the trigger offset by 360deg? Quote Link to comment Share on other sites More sharing options...

Adamw Posted December 26, 2020 Report Share Posted December 26, 2020 Yes, try adding or subtracting 360deg from your present trigger offset. You may be sparking on exhaust stroke rather than compression stroke. Quote Link to comment Share on other sites More sharing options...

Igt (+5vol) I insert the ecu, the ground I install the screw of the distributor,the +12v I use the blk/yel cable of the distributor. Is this method correct?

Why does my coil1 become hot and cause damage? Could it be caused by incorrect trigger offset? My trigger offset is now -85. I read the previous comments and they put it around 274. Is this correct?

Adamw Posted December 27, 2020 Report Share Posted December 27, 2020 The only thing that can make the coil heat is either wrong wiring, or the spark edge is set wrong like I mentioned in the first post. Quote Link to comment Share on other sites More sharing options...

My engine can work normally, but the rpm can't work. I know I need to add tacho booster to operate it. I want to know if I can use this in the photo to operate it?

Adamw Posted December 28, 2020 Report Share Posted December 28, 2020 No, that device will not be suitable, you need a device to generate an inductiive spike. Quote Link to comment Share on other sites More sharing options...
