BM3 Flex Fuel and Motiv Reflex wiring

[alfi.mke]

Have a (probably) dumb question. If I have a bm3 flex fuel kit installed and buy a PI setup including motiv reflex, will I have to undo the wiring for the flex fuel to install motiv?

Welp, you got a couple of options.
-If you don't want to pull out the BM3 ECA+wiring to the BDC. You can use the posi-tap wiring that comes with the reflex, to get the can signal for Port injection

-you could also pull out the BM3 BDC wiring and the ECA, keep the BM3 continental sensor, and use the reflex as the ECA and port injector. This is going to cost extra because you'll need to get a plug n play harness for the reflex.

I honestly would sell the bm3 flex and run Reflex+ with a PnP harness. Future proofing for, water/meth, nitrous, LPFP, EWG ect.

Ok that makes sense. Guess I gotta decide on port vs DI now lol

Yeaaaaaaaa about that. You'll have 33 pages to read through. Or you can just go PI and get it over with.
