No I think the install was fine, JB4 and BCM always worked initially once I got the BCM settings right. But when I added the WMI kit things went awry, I think my FSB might have had issues my car would not run normal until that was removed. I probably could have put the JB4 and BCM back in but I was so frustrated I just sent it all back to BMS for testing. If the FSB comes back with no trouble found I’ll really be scratching my head.

The WMI kit did work, but it may have been intermittent issue, just no way for me to tell.
