Yes. It will be the easiest solution and I can use the cables I have.
The TB's bracket would bring the cables over the valve cover (ugly).
And the current cables don't fit the bracket holes.

Pretty close now.

Looks like you've got a GM knock sensor screwed in there;
how did you choose a knock sensor, since there are a plethora of options?
[very incomplete list.....]
10456288 (4.3 and 5.7)
10456287 (5.0)
10456549 (7.4)
10456208 (3.1)
10456209 (2.2 pushrod)
I have heard the "bore diameter" thing before, but I'm not convinced.

Not sure how else you will decide then...

Pretty sure I got one for a 1993 Chev S10 with 2.5 Duke.
That's the closest SD4 engine "relative" - AND they have the same bore.

It's in! The engine runs!

Not very driveable at present - fuel map is all wrong.
Have contacted the fellow who helped TunerPro it last time.

Also, thanks to Cody, I was able to obtain the #163 Indy Parade Car Plate.
So after 33 years, it's can again be shown on the car it belongs to.

Do you happen to have a part number? I don't see a knock sensor on GMPartsdirect, Rockauto, or Advance Auto sites.

Oops... I think it was a 91 S10...

It was finally pointed out that the jumper settings to configure the NVRAM board to run the TBI probably weren't right. (didn't get a PDF with the thing)

So once I get that corrected, it may be "start from scratch" again.

BUT... it may be better and faster progress.



One of the cleanest SD4 builds that I've seen. As for tuning are you scanning and taking a log? Those early C3 ECM's can be tricky to tune but the guys on the Moates forum seem to have the process down pat.

Thanks Dennis

I'm completely set up using TunerPro RT (Real Time) 'live' emulator that can also scan and datalog.
All through the ALDL port with a 1227165 ECM : https://pcmhacking.net/foru...topic.php?f=27&t=356

I'm still checking a few things and may need to start with a different BIN than I have now.
These guys know their stuff too: http://www.gearhead-efi.com...7248d86a7e5f6178e6b6

I test drove the Indy today.

Even with the rough tune - it's never run this good!

I am making progress.

I got most of the base parameters in my BIN in pretty good shape.
Got my fuel grams/second figured out. Idles great at 13.5 - 14.0 AFR.
RPM was be too high when engine started hot or cold - fixed that.
Took a long time for RPM to come down to idle from hot or cold start - fixed that.
Engine took too long for RPM to come down to idle from blipping throttle - fixed decay rate.
Other minor changes in base parameters at this point only. Haven't touched any fuel/spark tables yet.

So now the SD4 starts good, idles quite well for 'lumpy' engine and is quite driveable.
I will be driving with TunerPro RT and recording Datalogs to to see what it needs in more detail.

Solved a minor problem I was having with ECM throwing a Code 24 for VSS (Vehicle Speed Sensor).
CEL (Check Engine Light) would come on at about 4800 rpm when accelerating and engine would buck.

Here is what playing back TunerPro DataLog showed ECM was seeing.
I'm accelerating "floored" (See TPS, MAP, and RPM) in 2nd gear +60kph when ECM suddenly thinks I'm at 0 and cuts fuel.

Just an update...

I finally FOUND the source of the problem causing all the headaches.
An intermittent short of the battery cable near the starter on a heat shield.

On the '84, all the supply wires with fusible links connect there too.
So anytime the short touched, the ECM etc. all lost power for a milli-second.

New cable fixed everything. And it is now well protected.

This engine has NEVER run so well before...
Much, much better than the carburetor or Fast TBI on there before.

Glad to here it's running better. Does it seem to have more power ? How about mpg. A sound video would be cool. Any tips on your intake mods for the injectors, like hole sizes and depth if stepped. and angles. Keep up the great craftsmanship, and ingenuity.
