Quick update --
Single DBW Throttle Body - EFI project reached a fresh milestone today. Erik of Sports Purpose Garage spent the better part of the day installing a tune into my ECU Master Black while also getting the DBW pedal and Bosch 74mm throttle body synched up & calibrated. The black magic that I still cannot wrap my head around is the synching up of the hall-type cam & crank sensors. His adjustable Snap On timing light verified what he needed to see and lock in the ECM. Good stuff for sure!
Car cranked up pretty quickly once the above were dialed in.
He did show up in his client’s 930 Safari build that’s been underway for the past 8 or 9 months. Not sure these photos capture the color – but Moonstone is just wicked and perfect for such a unique car. I don’t know the specs, but you can definitely hear it coming and going as the turbo whistles loudly like a modified F350 Super Duty at a stop light.
Late this afternoon, I decided to hit the street and cruised some wide-open country roads around me in the ’76 coupe. I set the laptop / Black ECM on for AutoTune and started a data log file. After 15 minutes or so, I made it back successfully to the shop. Let me tell you, this car sounds and feels great right now!! I definitely have a lot to learn and tweak going forward, but no stumbling, nothing odd happening that I’m aware of. It may be running rich. And if I was successful turning on (and subsequently saving) the autotune and log file, then I have something to review and play around with. My clutch cable needs adjusting – as I now have it too close to the pedal board. And the DBW pedal needs adjusting so it’s less linier and mimics the analog pedal I’m used to.
I did toss on these 993 brake cooling scoops that I purchased from our host about 3 or 4 years ago and had never installed. I remember reading about them here on the forum. They simply tuck in nicely against the caliper and rotor backing plate. We shall see … I’ve never run out of brakes on my mountain weekend rallies in the past, and I’d guess the more fresh cool air the better.
Good times – Hope to slap more miles on this on-going project in 1H2025!
