Injector Setup 550/1680cc
Does anyone have the correct injector setup for the datalogit with this fuel system and 550 primaries and 1680 secondaries?

I am the "ONE" who discovered that the injector transition vales for "%" and "ms" were bad even for the stock injector setup. Using the Datalogit, the transition was logged and displayed in a chart format. It showed that the primary injectors dropped of too much while the secondary injectors came on way too strong. This caused a feeling of leanness but actually was too rich.
Many tried correcting this by using the INJ Overlap table but that was a bandaid.
My way is the best actual fix to almost correct the problem. Still is a little off but that is the best the PFC can do.
Email me if you really want to see the charts.

The issue is no i cant get the car to start and after a few times trying i pull my spark plugs and they are soaked with gas. i am using 4BUR9EQP plugs. I checked my battery and its only has about 10v but the battery is quite old and i already plan on getting a new one. But i hooked up a jump box with a constant 12v to it and i get the same problem. Is there something wrong with the tune im using or is it more severe. Also, on my FPR, i seem to only be able to get ~32 base pressure with no vaccuum. I believe thats another issue in itself so if anyone has an idea about that, id greatly appreciate it. This is my first rotary so im trying to learn as i go. Please excuse any ignorance.

I had this issue yesterday with the same fuel setup, I adjusted the TPS a touch clockwise to read 1.00 volt closed and she idled fine all day at 1200rpm's. Today I went out and killed power for the PFC to re-learn idle because it was hunting yesterday and I can't get her to idle at all. I didn't change anything, can't figure it out!
