What other issues did you experience? I just installed the one I received from quantum and I get check engine light DTC for P1765. Also when I try to shift into second gear, nothing happens. I had no trouble codes on my original ECU or issues with shifting. Sent an email to quantum but waiting to hear back. Otherwise everything is working as expectedJust a quick update, George shipped the new ECU my way, might take a bit to go through customs. The first one I got from quantum felt really nice to drive, but as George said, it had A/C issues and some other quirks. Looking forward to the new one!
