I was trying to solve the stalling issue today. Until now, I had a jumper to feign neutral and allow the car to start since my actual NPS is backwards (open in neutral, closed in gear). Well I fitted a relay with a normally closed config to reverse the NPS and wired it in so the car only starts in neutral, when I'm in gear the ecu knows it.
100000% smoother take offs and low rpm operation. I figured the slight bogging was either me or the clutch or a tired engine, but no. I can now be crawling along in first gear at like 1000 rpms, and applying the gas no longer makes the car buck and jerk.
Still occasionally stalls at stops tho.
