After 7 very frustrating days, I finally got the car running this morning. Previously, I had the engine control system (MS-II) mocked up on the workbench, driven by a trigger wheel on the drill press - ignition, injectors, everything worked fine. Somewhere between the time I had the system running on the bench and getting it all installed in the car, I damaged the control unit. It would cycle the fuel pump with the ignition for a while and then it stopped doing even that. I spent a bunch of time tracing circuits, checking grounds and reinstalling software but it still wouldn't work. Everything pointed back to the processor in the control unit. I decided to order a new one (MS-III) and repair the old one later. An extra surprise is that the new controller uses a newer tuning program - one that was not compatible with my old laptop. UGH! I ended up having to get a new laptop as well. Last week was an expensive week! Once the new one engine controller arrived, I spent some more time double and triple checking the wiring to confirm it was correct (it was). I set some base fuel requirements, installed the controller, set the fuel pressure and the car started almost immediately…..then died. I had the parameters set too rich and it took me a while to sort out the changes needed to lean it out since the old software and new software functionality is different. Of course I fouled the plugs and had to change those too, at least I had spares on hand. Last night I had it real close to running on it's own but ran out of time. When I woke up this morning, something clicked - went out to the garage at 7am, made a couple of adjustments and within 5 minutes it was idling on it's own. I do not have the alternator, water pump and radiator in the car so I can't run it for very long. I wanted to make sure it was all going to work before installing the radiator. I didn’t have a video camera with me at the time but I did get a picture of the gauges registering oil and fuel pressure.
I'll have pics and video after work tonight....
