wheee!

Awesome guys! Thanks for the input!

Pretty much what I had in mind. Thanks for the confirmation! I think it might be a bad pump/bad connection as there is a lot of corrosion under there and I'm not confident the connections are good...

So jealous.....!

I have installed the newest version of the ECU (with IC's) into the car. I played around with the car a bit this weekend and turned it over again, just to see what happened. No fuel is being pumped so once I diagnose where that fault is I can hopefully fire this engine up at least once before I tear the whole car down! I have the FI bible so it shouldn't be hard to source the fault. Just need decent weather to work in the garage! Sent from my iPizzle ringy dingy device....

, I should have asked earlier! Sounds awesome Matt! Love the throttle linkage too....

Was really hoping for a first start up video.... Sent from my iPizzle ringy dingy device....

I agree 100%. Newer is always better and more tune-able. I haven't seen a Megasquirt system in person but for some reason I am drawn to the Hellfire option, probably because of the name... Now all we need is someone to finish it!! Sent from my iPizzle ringy dingy device....

Was disappointed to learn the remanufactured alternator was still an externally regulated version. Oh well. I will buy a new one with internal regulator. Sent from my iPizzle ringy dingy device....

That will be a good thing all right! Sent from my iPizzle ringy dingy device....

I have never started my car... It turns over but I have no fuel. Either a dead pump, dead relay or clogged line. Got spark, but no fuel. I suspect the pump. But as I was planning a complete teardown, I haven't put a lot of effort into starting it. Maybe this spring... Sent from my iPizzle ringy dingy device....

Mine was a Canadian car, and as far as I know, the ECU with multiple pins was the original one with the car....

This is interesting.... The ECU that was still in the car is an old style and it has all the pins on the ECU connector...weird This is the older ECU style that was in the car. This is the most modern of the ECU styles with less pins.

Updates! These are the hi res pictures of the more modern ECU

I'm hoping he meant this year...! Sent from my iPizzle ringy dingy device....

They didn't have the printer technology either .... I will get some hi res shots of the dips soon. Maybe this afternoon if I get off work early Sent from my iPizzle ringy dingy device....

I will remove the unit still in the car as soon as it warms up enough to get into the car. It's been -27 degrees celcius around here for the past few days. My workshop isn't heated yet... Supposed to warm up soon. I will take it apart as well and get a picture of the inside of the newer C-12 board with it.

, maybe it's my extra ECU, the lost holy grail! Sent from my iPizzle ringy dingy device....

Confirmed the build date today too. Apparently there was a change in the production run in 1976...

Quick correction: engine was rebuilt in 92/93 by PO and his father. Changed it in original post too. I'm hoping to get more details on what that entailed prior to my tearing it down. Sent from my iPizzle ringy dingy device....

You are correct on all counts. I have to remove the third ECu and open it to inspect the internals. All three were in a box in the trunk of the car when I bought it.... and the car hasn't been run since 1996. I will get some more pics of the DIPs for you soon. Unfortunately I reassembled them and took them back to the shop last night. All I had at work was my crappy cell camera. When I get the other one out I will photograph them both with my Digital SLR Thanks for the link, I will look into that! I like the idea of the Hellfire as I have two engines and I would like to run the stock motor at first (for the wife) and then rebuild the other as a hi-performance overbore with carbs or ITB's. No point in doing that until I have a megasquirt or Hellfire to tune it....

Excellent suggestions and info Captain! Thank you!

SO very strange indeed. The resistors and capacitors loaded into that terminal bus in white really confuse me. Overkill in one case for sure as they probably only use the 4 like the other boards...

I think I remember reading about the potentiometer on the coolant temp circuit somewhere, but I was under the impression it required a lot of constant adjusting to keep it dialled in through the rpm range etc.... I am going to use the most modern of the three ECU's, just for component reliability sake. It would be nice to replace them with the Hellfire for tune-ability and future expansion though....

I have been patiently waiting for superlen to update that thread.... I think the Hellfire sounds great! I am just concerned over the vast differences in circuit board design between the two ECU's. Similar pinouts, but different resistors, transistors etc. whole sections of the cb are different... I was concerned I had an ECU for a model that did not control the fuel pump relay....

So I have three FI ECU's. All of them are A11-600-000 but different lots. How do I know if they are the same or if they are for different model (year) 280's? Pics of the two that are out of the car at the moment. Logic board says A12-001 003 6cyl This one is from Lot 6825 This one is C12-001 004 N This one is from Lot 7Z07 Does anyone have experience modding these boards or even identifying them?
