Not sure what the issue is but after moving from non-seq twins to my single setup, I am unable to get datalogit to control my idle. No matter how much fuel I remove my afr's don't change. I went back to an earlier version of datalogit software to see if that was the issue but it didn't help. I'm running no O2 feedback, ignition, and no ISC. Running stock 550's with 1300's, same as I did before going single. Had no issues before so really am not sure what the problem. Could it be the EL system? Any help would be appreciated.

Couple of notes I did try reinitializing the PFC and have checked my TPS values. Also when I first started the car it seemed like it started to remove fuel like it should but then "learned" around it and went lean. My datalogs are showing way more ignition timing than its supposed to compared to what I have in the map and the water temperature doesn't seem to coming up in my watch's they way its supposed to though in the monitor its correct, and its not that I'm looking at the wrong adanced/basic water temp.

 

I assume that the air pump was removed, and the O2 FB is switched off.
The PFC will allow only so much fuel removed at idle no matter what values you put in the BASE map or INJ (fuel corr) map.

Your next step is the Settings 3 INJ ADJUST table.
Last resort is lag.

 

I'm hoping its a leaking injector. I never had problems leaning it out before which is what really bothers me. Yes airpump removed, o2 off. May also check fuel pressure. Anything else?

 

Well, pressurized the rails no leaking injectors. Did have an o-ring that got smooshed on the primary rail. Replaced it. Checked my fuel pressure it was 50 psi. Changed my fpr with another spare. No help still sitting at 50 psi. When I pull the wire at the diag conn. the pressure instantly goes down to 38. So it looks like I'm overrunning the FPR.

 

Time to adjust your FPR!
Mazda idle FP is about 28-32 psi.
