So tried to fire up my new build wouldn't start so I check for spark and found I have none. While going through the trouble shooting I found that the small red key hot wire from the box is only getting 10volts during cranking. How do I fix this issue

 

throw the MSD pile of **** into the trash and use a OEM distributor/coil setup.

ps. while cranking system voltage @ 10v is normal.

 

I agree, toss the pos msd box and go with what works. If you do your do research, you will find the msd units available to the public do not work. They do not have the ability to start and stop rapidly, so you end up with a constant on spark. I will not ever recommend their use. If you must spend money, change over to coil on plug units, otherwise go with what works. The tried and true oem.

 

I was having lots of blowout when getting in the revs on 360whp. Looked into COP but Hondata says it doesn't work with jdm ecu. Does anyone know if I need to cut and seal the green loop. With 82933 distributor

 

my setup made over 440whp using OEM distributor/coil/wires and ngk heat range 8 race plugs gapped to .030 for years. no spark issues.

 

I've see a few issues with the MSD setups, ditch the crap and go oem.
