I want to give a big thumbs up to the team at CPG, in particular Chris, who has been helping me with my FAST EFI 1.0, and this forum who've been lending insight as well. http://www.cpgnation.com/forum/threads/ez-efi-gremlin-need-help.26560/ We've spent the last few weeks chasing a gremlin that really stumped us. While I understand its rare for the ECU to have an issue, it appears that CPG service dept infact did find one in mine after I sent it in. Keep in mind that my EZ EFI has worked flawlessly for the last 3 years, and then suddenly after what we believe was a voltage spike, the system became inoperable. WHAT DID CPG DO? Chris and team reflashed the ECU, updated the firmware, and ran the system on a test engine for an hour.... and now are returning it to me for install... NO CHARGE. ***THAT's CUSTOMER SERVICE! You've won my future business for sure. Thank you for spending the time you did on the phone with me to sleuth out the problem, and then to take the time to get it right. I'm truly impressed and grateful. Can't wait to get my Vette back on the road.
