Flooding during cold starts, FD RX7

[Pete_89t2]

Some background - I recently got my G4+ back from Link after they serviced the ignition drivers/header connector. Reference this thread: https://forums.linkecu.com/topic/12884-troubleshooting-a-sudden-no-spark-issue-fd-rx7/

Upon getting my ECU back a few weeks ago, I had no problems loading my existing/unchanged calibration file onto the ECU, running a few pre-start tests (coils, injectors, etc.) and firing up the engine. Ambient temps were significantly warmer then, ~70*F vs 40*F now. Anyway, the car fired right up fine, and ran fine - I let it reach operating temperature, had it running perhaps 30 minutes or so until moving it onto my lift where its been parked to do some other work underneath it in the two weeks since.

I'm now having a problem now where the engine floods profusely when I attempt to start it - I know it's flooding because when it does, fuel will leak past the metal exhaust manifold gasket leaving a mess to clean up. Tested spark & compression, and both are good. Today after tweaking the cold start enrichment functions to lean things out a bit, and cleaning the mess from the fuel, I got the car to fire up and run for a few minutes, but as the ECT temps approached ~90F, it died again. I tried restarting a few times, and it would catch and run briefly and then flood out again, as evidenced by the fuel leaking past the exhaust mani again.

Not really sure if this is a tuning issue, or perhaps leaky/malfunctioning injectors at this point, so I was hoping someone could take a look at my tune file & log and provide some advice.

Here's the link to the tune file: https://drive.google.com/file/d/1nQZskfVPU3lOYqef57xHLf_m92gXHt8L/view?usp=sharing

As far as the injectors leaking, I tested for that by pressurizing the fuel system (engine not running), and letting it stay pressurized at the 43.5psi base pressure for about 20~30 minutes. There were no external leaks found, so if any of the injectors were leaking or sticking open, fuel would find its way into the combustion chamber and/or leak from the exhaust manifold gasket. No fuel was noted after pulling the plugs or leaking past the exhaust mani gasket, so it seems the injectors are OK?

Thanks in advance!
