0411 running a 2.5L Jeep engine

Can someone explain the high octane / low octane tables? As in how does it know which one to use? There is a big difference in them.
The new reluctor seems to run better than the old one. The new one is a single pattern and the old one is the double pattern.
I'm running a F body 5.7 tune and so far it runs ok. I have driven it up and down the dirt road I live on. I haven't driven it on the road yet.
Tomorrow I'm going to take it for a drive and see how it runs.

there is a spark scaler, more knock will bias the timing to the lower octane spark map.

I'm running the 12212156 OS. So it uses the High map until it has knock then jumps to the Low map. Ok that makes sense.

yeah all ls1 onwards stuff works like that. not OS specific.

Not 100% sure but I think when it knocks it interpolates between the 2 maps.

In the attached XDF look at the parameters under Engine Calibration>Spark>Octane Learn. These parameters are what bias the timing towards either high or low octane tables.

All I can say is WOW. That XDF is very detailed.

Ok, when I look at the flag to enable it, it's not checked. ( B6220 - Adaptive Octane Learn Modifier Enable )

So does that mean it only uses the high or low octane table?

I've found a place that'll laser cut parts. So I sent them this drawing (the PDF) to see how good they do. I ordered 4 of them and it was under $100. That included zinc plating.

I'm pleased to report the parts are very nice. They came in a blister pack and well protected.

Now I need to know. Can use this reluctor with the 0411 as long as I use the correct CPS.

I'm hoping to be able get back to this little project next week. I'll post results when I can.

the vortec 4x crank sensor will work on that single pattern wheel. LS sensor is for dual pattern wheels.

I'm using the black LS sensor and it seems to be running great.
I think I have one of those around here somewhere, I may try it and see if there's a difference.
