Elite 750 on 20b?
So anybody running an Elite 750 on a 20b on here? Planning a 20b project and looking at using the 750 since it looks like it will control 6 injectors and coils plus it looks like it is flex fuel capable. Any problems using the stock CAS and TPS?

I have to do more reading on the closed loop boost control on the 2500 but can you select different boost levels on the fly like stand alone electronic boost controllers (Greddy)? Say set a low and high boost levels? So I can cruise around the street on low and then hit a button for high boost levels?
Can the 2500 control 9 injectors? I think it can do 8?
I will probably go through you again C. Ludwig for this next harness. Love the Sprint RE harness you built for me a couple years ago

The 1500 and 2500 can do multiple levels of boost control. We usually use the AEM 12 position **** for 12 levels. Overkill but, why not? The 750 can use the trim ***** as well but it's a duty cycle offset and not a boost target offset. Flex fuel control will automatically trim boost based on ethanol content as well.
The 2500 has 8 drivers. If you want to run 9 injectors, I'd suggest a 3 stage system. Primary and 1st secondary stages would be setup as sequential. The 3rd stage would be run as batch fire. No real downside to not using sequential at that point as fuel demand dictates big duty cycles anyway. If you need all 9 injectors to be fired in sequential, then we can pair two secondary injectors on each driver and just do two stages. This is how you would have to wire the 750. Either way works fine.

How would you go about using the 2500 dual channel knock control on the 20b? Would one sensor be on say the rear housing and the other on the front or would both go on one housing?
How well does the knock control work on the rotary?
I noticed that the 750 doesn't have knock control but 2500 has dual channel control

Knock control seems to work pretty well. I have a couple 400-ish who setups that are running consistently strong. They'll pick up some rouge knock on occasion and take action. I really don't think it's going to save a 1000hp drag motor though. Things just happen too fast and with such great affect at that level. I'm not sure any system would work quickly enough in that situation.
The couple 20Bs we've setup I've used one sensor on the middle rotor housing.
