Haltech Nexus Rebel LS
So a question for the Haltech guys. I was just looking at the new Rebel:

How does Haltech handle the wiring differences between the Gen 3 and Gen 4 engines? They don't seem to have specific kits for Gen 3 and for Gen 4, like Holley does.

isnt the only difference the cam sensor pinout? I have never bought a harness from haltech but id guess they will use a deutsch connector with a sub harness, thats is how they do other similar wiring.

Tried to find the video but I think it’s gone. It was on the terminator x product page a few years ago. Based on that I’m assuming that’s basically what the haltech is doing.

Hall effect sensors are generally passive devices so they output whatever voltage that is input to them within a range usually ~5-18v.
Afternarket ecus will consider a ‘low’ input to be 0-0.2v and anything above about 0.75 volt to be ‘high’ so it doesn’t really matter what the sensors run at for binary inputs.
It would be interesting to test a p01 to see if it triggers off a 5v signal. Ultimately the processors will trigger the same but the analog front end will determine what makes it through.

back in the day holley had a video saying if you don’t know your combo to buy the gen IV setup since the only difference is 5v vs 12v power to the crank and cam sensors. Apparently the 5v sensors will deal with the 12v input but obviously the other way doesn’t work.

Thanks for the clarification!

Haltech got acquired by Race Winning Brands last year so I'm not surprised to see them go after more of the market.
It's interesting, in the very beginning of the Gen 3 / LS scene you had FAST and then BS3 as the primary options for an aftermarket ECU. I remember looking at my BS3 when it came in, just bundles of wires for the harnesses talk about scary lol.

The app is like the little screen wizard with the Holley. It's to get the basics setup quickly and if a fairly stock LS maybe all you need.
You also have the full NSP platform to fine tune whatever you like for far more control.
I use a R3 and NSP is great. The Rebel LS should make it even easier to get a LS up and running.
