AEM EMS and RC750 Injectors; Fuel MAP

[HydeDW]

I recently resurrected the VR4 w/new engine build. I was running AEM EMS prior with RC550 injectors. The new build will flow more air and this build is with RC750s.

AEM is V1.19

I rescaled the fuel map I was running prior for the 750cc injectors but she is rich. Manual overrides (in idle load region ) brings A/F reasonably into check but RAW values in that map area had to be adjusted quite a bit lower than the rescale starting point and that puzzles me. (O2 feedback is off by the way)

I'd like to take a look at a full map someone else is running to compare if there is just some diff in the idle zone or if the whole map might be subject to needing further rescale!

The parts and piece specifics of my current build are in Sig. If one of you have a reasonably close matching build and running 750cc injectors and AEM, I'd appreciate a look at your fuel map - either copy into Excel (including the breakpoints info) or send an AEM Cal file.

The "puzzles me" in prior post is puzzle no longer. I had the FP Solenoid plugged in and that's a 'no go' with AEM ECU. The FP Solenoid ground is always active (on) when ignition is on and that bypasses engine vacuum to atmospheric; effectively running higher fuel pressure (43 psi) at idle vs. ~36 psi with vacuum. My 550cc to 750cc scaled fuel map works fine now in idle region with minimal tweaks.
