The dead coils are the ones that touch with the car sitting on them, so that would be all of what is in that picture.

Because in 1968, D-Jetronic was an open loop (no feedback) system with a massive, simplistic brain susceptible to being damaged easily by heat and vibration. The manifold pressure sensors were especially wonky and liked to go out of spec. None of the other sensors was particularly robust, either. Oftentimes the coolant sensor would either die and keep your cold-start inector from working or die and make the cold start injector work all the time. Take your pick.

Believe me when I tell you I write from the perspective of a D-Jetronic owner (my late, lamented 1972 SAAB 99e). Manufacturers chose the CIS system because it was more robust and more easily diagnosed (my late, lamented 1983 SAAB 900 Turbo). EFI had not come of age yet. Later cheaper computing power brought good solid EFI home by the late '80s.

And that would explain it... Thank you...

Crack in the floor

Jacking rail bent all to hell and back

The rear bumper cover was held on by zip ties...

No idea why this part of a GM seatbelt was in the car...

Also the wiring is kinda of a clusterberkeley and the water temp gauge does not work...

Clean and repair grounds.... Hell, clean and repair all electrical connections...

Ok so since the last update, we have replaced the water temperature warning light sender, put a Jegs high back polyurethane seat and roll bar padding in the passenger side, removed the carpet from under the roll bar and replaced the hardware with grade 8.

Still need to fix the steering wheel not being straight, the windshield wipers not working, and a random buzzer going off. There is an autocross school this weekend that we are going to do so hopefully it will hold together.

The way Bosch did things, the EFI was the cheap stuff, while CIS was for high-end cars. All of those precision machined parts weren't cheap, after all.

CIS, when working properly, is quite responsive, seamless, and just about idiot-proof. The EFI setup they had (D-Jetronic - UGH) was not so nice, but it "worked". Bear in mind that the fuel injection on a '94 911 Turbo isn't all that much different from what is on that Scirocco. The main thing that changed over the years was ever-finer warmup and lambda control, the actual control units didn't need to change much at all.

This is an awesome way to get some seat time.
Just make it driveable/reliable as possible & hit as many events as you can.

Well I had a blast but my co-driver beat me by two seconds. I need to find some more speed next autocross.

The car is a blast to drive but after driving it for a bunch of Saturday doing instructional drills and the 6 autocross runs Sunday I am sore all over...

Results from the day.

In other news, I found out I am going to miss two events. I wonder if SWMBO would be pissed if I went to an autocross instead of doing engagement pictures or our wedding...
