V8 Carb EFI conversion TBI Injector settings

EMU BLACK / CLASSIC
1

Hi all,

I have an EMU Black and I’m going to use V3 firmware and I’m starting with wasted spark (no cam sensor)

The engine is a Chrysler 400CI (6.6L) big block and I’m going to convert from carb to EFI.
I’m using a Holley Terminator X 4150 Stealth throttle body.
This throttle body has 4 1050cc injectors (one for each barrel) and integrated TPS.
The intake has a divided plenum.

1, 4, 6, 7 are connected
2, 3, 5, 8 are connected
Injector 1 is closest to 1 and 4
Injector 2 is closest to 2 and 3
Injector 3 is closest to 6 and 7
Injector 4 is closest to 5 and 8

What would the best injector settings / strategy be?

Is this ok, or would it be better to use a completely different strategy? I think the injectors are too big for Batch injection.

Up!

Question is still open :slight_smile:

Get that thing running and then optimize. It’ll run on whatever you put in there as long as you’ve got the injector mapping right. You’re going to run this alpha-n? cool project!

Does the fuel inject above or below the blades on the TBI unit?

Above the blades.
Maybe a bit hard to see, but you can see the ring of small holes down the barrel just above the blades
