Spark plugs
Re: Spark plugs
On thermostat housing. We are using k20 coils.
Re: Spark plugs
what about the ground for the CPR harness inside the vehicle?
Re: Spark plugs
I check it yesterday night. Gorund at a23, igntion power at a24, icm at a22 and altc at a16. I did the troubleshooting also every step is ok. Traction control wirings is also wired to a23 and a25 does it cause to this ?

Can you start your own thread in the CPR section of the forum: http://www.hondata.com/forum/viewforum.php?f=32
Re: Spark plugs
I'm not sure which plugs were installed in my car but I did end up burning a small hole in the mother board of my P72 ecu, is it possible the electrical surge that is sent back from a non resistor plug could cause that? I read earlier in the thread that non-resistors can cause idling problems which is something I'm experiencing now.
Re: Spark plugs
Post a picture of the burned ECU.
Re: Spark plugs
I don't have a picture of it but I checked my plugs (same ever since I swapped the engine) and they are a resistor type.
Re: Spark plugs
So i purchased these for my turbo b series build. Not chasing big power like 300-325 or so. Would these plugs be too cold, or they are ok?

Re: Spark plugs
You should discuss the plugs used with your engine builder or tuner or both.
Re: Spark plugs
That's me and me😆 guess i better look at how boost affects spark plugs
Re: Spark plugs
Yep with all the research i did, it seems these plugs are the plugs to go to . I'm wondering what gap will be fine. I wrote down all the gaps and i believe they are at .031 thousandths and i think I'm going to start at .025 clearance and see how it's looking.
Re: Spark plugs
That's a decent starting point. I have mine at 0.020".Ichiro718 wrote: ↑Tue Nov 08, 2022 4:23 pm Yep with all the research i did, it seems these plugs are the plugs to go to .

Re: Spark plugs
Ayeee, so is that where you ended up? If you can explain your method of processing and execution please😁
Re: Spark plugs
If you start breaking up as boost comes up, you can try tightening your gap, as it may be blowing out the spark.
