A while back a friend of mine told me the MSII didn't work for the rotary engines. now that im building another S4 I have been finding conflicting information.

Can anyone confirm. the successful use of the MSII 3.0. and if so, Do i just do the standard PCB mods? (switch 1 resistor, take 2 points off the CAS, and add 1 signal conditioner)

would I still need to remove the 2 points from the CAS?

Sorry about all the questions. I'm having Information Overload.

 

MS2/E 1.0.2 runs a rotary just fine. On a 3.0 board you will need to change the bias resistor for the air temp sensor. If you're running stock coils, 3 resistors will need to be added. You can run an unmodified CAS by adding a second VR conditioner circuit.

Quite a few people here, including myself, are running 3.0 boards and MS2 processors.

This thread has pretty much the info you need:

thanks for the info, sounds easy enough.
