Map referenced Safc

[Rubber D]

Hello fellow citizens.
I usually don’t need to ask questions, because the info is already posted. I’ve been running my car on e85 with 550cc injectors and apexi neo for a while (5 psi to4e/slow). Over the past year I changed the injector o rings 2 times. It seems the pintle caps don’t like e85. The other day it happend and after syphoning the cylinders and rebuilding the injectors I figured to go back to 93 pump.
Sorry for the long story, while going over tips on tuning out the fuel, I read about people in other platforms using a remote map sensor to feed a signal through the tps input of the apexi. It looks like a linier fuel table, where you could adjust fuel depending on rpm and manifold pressure. Sounds better than rpm and throttle position. Has anyone done this before, and if so how did it work for you. Thanks a bunch.

Thanks Jedi..
I run a draw thru maf with a recirc fv bov. I built a ms2 3.0pcb to run the car for later, still need to get an autotune harness and some other components for it. Also want to wait to install during the winter.
I wasn’t trying to convert to map now, just use a stand-alone map sensor to load a 0-5v signal to safc through the tps input. I’ve read about it on other forums like allsentra and thought it was cool. Maybe someone here tried it before.
Btw thanks to all the pioneers for the info, peace
