Re: Hondata locked to old ECU & Engine

Here is a pic of the old ECU, and a tag for the new one we purchased. When my son comes back from school, I can get you a picture of the new ECU if required.
Thanks for the help!

Hello,
I have an issue with my Hondata being locked to my original ECU which had to be replaced. My son blew the engine in my 8th gen 2009 Civic Si, and through the process we purchased a new ECU, and an engine. I am hesitant to try and put the old ECU back in to the engine (to unlock it), as they ...

Wouldn't a shorted/seized alternator fry an ECU? Or are you thinking that there is a grounding issue (that only seems to be present with the old ECU)?

OK thanks for the quick response, I will give that a try.

Thanks again
