Unsplice the wires. And yes it worked for me and others I suggested it to.

I ran power from the battery to a relay. 1 relay for coils and the other for the box. Just don't splice into the ECU power or ground. I know the directions say to splice into the ecu wires, but to hell with the directions.
do you have a diagram you can share on how you wired up the relay to power the Hondata CPR box?

A diagram is not needed. Wire the switch wire for the relays to a power source that stays on while cranking. The main power wire should connect to the battery or strong power source.

From what you're saying it sounds like I will need to use two relays, one to power the CPR box and another to power the coils? Does this look about right? I know you said to "hell with directions" lol but the ground source for the relay for the CPR box... I should keep that as close to the ECU as possible?

Sorry to bring up an old thread like this. I’m currently gapped to .018” and still spitting around 600whp. I plan on adding the relays but where are you tying into for the ground trigger source?
Thanks.

Gap 0.020-0.030". Both ICM pins are connected inside the ECU.
So your saying the existing ICM that’s in the ecu for a p28 is supposed to be left alone and we are supposed to plug in the coil on plug ICM into the open pin out (a22) ? I’m having the same issue and this is that last thing I can think of that is causing my random stutter
