INSW20 Posted February 14, 2023 Report Share Posted February 14, 2023 Am I sucking too much fuel off the port walls before I blip my throttle? Or what else am I doing wrong? Usually my blips are just fine, but on my drive home today (~40 miles) I had two instances after some engine braking where I had no throttle response. Tach stayed running the entire time, so I don't think it was trigger related. First time I was engine braking down a hill, got to the bottom and eased back onto throttle and had zero response. (no log available, ECU log filled up) Second time I was trying to blip for a downshift and had a dead pedal. Engine didn't try to die, just didn't pick up. Pretty sure this spot in the log was it. 5sgte - 2.13.2023.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 14, 2023 Report Share Posted February 14, 2023 Do you have oil pressure, GP Limit 1 or Ign cut logged? Your GP Limit 1 looks a bit optimistic for hot oil pressure around the idle area to me. Quote Link to comment Share on other sites More sharing options...

Your GP Limit 1 looks a bit optimistic for hot oil pressure around the idle area to me. I have oil pressure logged, at the blip attempt oil pressure is at 45psi, puts the limiter at about 5000rpm. Hot idle oil pressure is about 26-28psi at 1000rpm. Unfortunately my ECU log doesn't have GP limit 1 or Ign cut logged. Quote Link to comment Share on other sites More sharing options...

INSW20 Posted February 15, 2023 Author Report Share Posted February 15, 2023 If needed, I can try to replicate the issue during PC logging this weekend, if the log on my google drive isn’t useful. Thanks! Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 17, 2023 Report Share Posted February 17, 2023 Yeah I dont see anything obvious. I suspect it may just be a lack of fuel due to the overrun fuel cut up to that point. I would try turning ORFC off and then try to reproduce the problem with that off. INSW20 1 Quote Link to comment Share on other sites More sharing options...
