Great to have this much response in here. None so far from the electromotive forum...
I have monitored the fuel pressure gauge when activating the accellerator by hand in the engine bay. The fuel pressure needle is dead steady... always. So that looks to be OK.
Some thoughts to the Idle voltage theory:
If the Idle voltage really is supposed to be dead accurate down to the precise second decimal every time it goes back to idle, then I can't imagine I'm ever going to find a TPS good enough. You can't expect the potensiometer resistance be 100% accurate from one movement to the next, can you? I mean, there will always be some discrepancy...
If my memory serves me, I observed the same thing when I used the previous TPS on the 3.2 engine. It "lands" at random between for instance 0.86 and 0.82 each time the pedal is released. In my case now it is between 0.90 and 0.94. But it does not vary once it has landed. Then it is steady.
In an effort to solve this issue I have now made a complete rewrite of the entire map, using different UAP and TOG. Aditionally I tweaked the MAP figures in the left coloumns, so the map now effectively has a more detailed "image" of the area that is used for normal operation of the engine. (if that made any sense?
)
I also turned off the closed loop and tweaked the accell enrichments.
Anyway, I took some more logs, and it looks like you can now see the difference even more from a good one to the bad one:
Good one:
Bad one:
Looks like they both activate the injectors equally from the PWON figure, yet it still runs lean. THAT is probably the real key to this issue. But what can cause that? I mean, it looks like the ECU is activating the injectors correctly. (but are they really activated like the log says??)
-Very strange indeed...
