The V12 sure is perty!
Now that I'm over my project envy.... I remember reading somewhere that BMW treated the V12 like two six cylinder engines, in that they used two ECMs. Each managing a side. ...

I'm not familiar with the site. What diagrams are you looking for? Which application, etc?

1project2many, that's a cool project truck. How large of an injector did you use?
I seem to remember Terry Kelly telling me that because the $58 code from the 7749 was half the size (27128 chip)...

Welcome Andy!
Please tell us more about this 88 Cavalier, 2.3l V6.
Our GM 2.3L in North America was a DOHC 4 cylinder.
Is your engine an Opel design maybe?

there are much brighter folks here than myself, but I will take a stab at this. What you're proposing should not be too hard, but you will need to account for the (off engine) sensors whose input...

Ahh man.. I haven't lurked done my lurking in a while and was saddened by the news. Mark was such a nice guy. You could see it in so many of his replies. I'm sure I'm not alone in offering his...

My junkyard book suggests that the 16171199 ECM had no cross-references, and was a possibility in 93-94 trucks with the 5.0 and 5.7 engines. The 16168625 is also listed as a possible for that truck...

Welcome! Your projects sound like fun. Any pics ?

Welcome! Do you know what year the 350 TBI setup is? There should be some numbers on the computer.

If you're careful on the *removal side* of this project (unplug - not cut, etc), it should be very straight forward. Your ECM doesn't really care if gauges are plugged in, but make sure engine &...

Yeah Baby! Welcome Mr. Tim!
Just random thoughts: What EFI parts(if any) have you gathered?
The karmann gia needs turbo sunbird port EFI, as you just never know when you'll want to add boost!...

Nice build! I love the welded intake.
And I have to ask, did you complete Marine boot camp?

I think it was also a TBI system

my limited notes show BMHN as a 7.4 liter, manual trans from 1995.
16197427 ECM.

Welcome! Keep looking. Your name is still up.

Thanks Mark,
I'm there just as soon as project car has driveline bolted in and started up.
The peices are fitting together in my feeble brain, and we've exchanged email before.
You were generous...

Thanks Mark,
That was a very enjoyable hour spent reading, and I barely scratched the surface.
It's great how fasteddi started out saying that a 14 second slip would be fine, but then he was...

It looks like most of their VSS solutions are $100 or less. A phone call might be the best way to get the right part.
They have adapters that pass the mechanical rotation through to your...

fasteddi, that's flyin for a 3.1.
What heads are you using?
I'd love to hear about you build.
Mike

The old-time swapper place; "Jags That Run" has a number of solutions.
Do you have a speedometer cable drive on that trans?

Working from memory, I recall people having high-idle problems as a result of omitting VSS.
I believe that the vehicle speed is used in calcs for EGR operation, decel fuel cutoff, power enrichment. ...

Thanks Shannen.
I took my nephews and dragged the new short term project home tonight.

I'd forgotten that barn cars often have aroma of finely aged mouse pee....

Well, I was googling and minding my own, when I came across this awesome forum!
It's great that there's such an active group still tuning the older stuff. No, it's beyond great!
No offense...
