This is a very odd problem that I'm having -- didn't experience before the rebuild and hadn't touched any of the actual turbo timer wiring. For reference purposes, this is a Blitz FATT DCIII with built in boost gauge (hooked up). Here's the thing -- it works great when I turn the car off and go only to the ACC position with the key... The moment I turn the key all the way off to the LOCK position, the car starts idling at 100-200 rpm and eventually dies within a few seconds. Anyone ever experience this? I haven't had the time to actually rewire the timer as per the original installation instructions but perhaps its simpler than that. Thanks in advance!
