Email sent. I also grabbed 4 brand new coils and they reacted the same way. Then managed to get another p72 ecu and test. This time the sync light would not come on at all. Switched a21 to a22 and double checked grounds and still no light.

Put in original ecu and sync light came back. Not sure if ...

Also would it be worth it to send in the ECU and s300? I'm really just hoping to resolve this quickly to get tuned and get a run on the drag strip for the end of this year and this is the finale thing holding me up. I do appreciate your help.

Can you send me all the info that I would need to send the unit. It is brand new out of the box, wouldn't it be covered by a warranty to some extent? Also I can send it with a with a paid return label. Chadcarp@gmail.com Thanks

Does the logic ground on a26 play much of a role in the CPR, and where does that go to in the harness? I inspected my harness and that is the only wire that looked like it had some damage to it. Was going to rerun it but not sure where it goes to?

Also have the proper grounds on the engine and transmission, and yes the valve cover ground is on the one with the stud :-)

I'm using the standard harness that the CPR came with and it is a USDM p28 ecu. It does have the q37.

I got the car started and running off the stock distributor and the digital 6 Plus ignition everything seems to be running good. When I go to use the CPR I can't get it to start. All lights are flashing like they are suppose to(power on, ignition flashing and sync flashing for every 4 count of ...
