I have checked ICM wire directly from Hondata CPR box to ecu amongst other wiring. From what I understand culprit is ICM wire (variation B -red/yellow) and doesn’t make any difference If adjust. However, I haven’t actually test by continuity but only free-hand. Also, for some reason ecu began to act-up as I connect to software via data log cable and throws 16 error codes but doesn’t actually show codes. Sometimes will work fine and confusing since practically brand new from Phearable.com which specializes well with many Hondata products. I need your help please. I must add, I don’t have second s300 so very difficult to diagnose ecu. Everything appears fine wise inside ecu. I don’t see any burnt spots anywhere. In ecu and cpr box. All parts basically new and quite frustrating. All three boxes checked via smanager parameters.

Have you verified that it is connected to the correct ECU pin?

What happens if you connect it to A21 instead?

Issue has arose, again. Day 3 12/18 CPR Issue

Unfortunately, while driving just recently vehicle developed symptom, misfire. Eventually, the vehicle won't start. The issue found related to CPR IGN red light not blinking as required. Sometimes, the red light will blink, vehicle will start, but very randomly. The other lights function as intended to. Vehicle has function well for years now.

- cleaned grounds, checked wires pinouts, there no signs whatsoever of burnt ecu/cpr boards

Please Note:

Upon troubleshooting cop plate re-installation, accidentally smashed some wires but it only tore apart protective coating, applied electrical tape.

Please Help !

UPDATE: Car starts but no culprit found so may still be CPR issue since rough idle, misfire, and non-drivable yet.

Car was fine, switch camshafts and was adjusting fuel when lean cut was activated at 12.0 around 1 psi. couple days ago. This wasn't full throttle. Few minutes later, misfire began but disappeared until next morning. However, again disappeared so drove vehicle, for it to re-appear. CPR as potential culprit found since wouldn't start due to non-flashing red light. Currently will start, but misfire persists. Initial start since previous post, motor idle normal. Eventually, upon pressing throttle, misfire appears again.

-Seems like coil packs good, when plug removed, motor noise changes
-Will change plugs out when find ride

Please Note:
Please review attached data-logs of symptoms

Are you using resistor or non-resistor spark plugs?

Have you checked them to see the condition?

Update: car starts and idles fine due to spark plugs replacement install. However, will drive around block and verify everything's copacetic without any issues. They are BKRE8ix iridium, NGK2668 resistor type
