KTuner PRB hard to start
Posted: Tue Jun 28, 2022 6:37 am
Trying again with the PRB as a base for my turbo k24a4, and so far I have it running incredibly well. Tuning is harder having only 2 VTC tables, but no more lean condition in boost and it cruises like a stock vehicle.
Cold starting is difficult, seems like there isn’t enough fuel or ignition is overly retarded, it turns over but stumbles & struggles to actually fire up. Typically takes 2 tries before it will start, but after it finally catches it runs & idles flawlessly.
The only setting I could find was the cranking fuel, which I have been increasing slowly but it hasn’t seemed to help at all.
Is there another setting I should be looking for to fix this?
(Engine fired up immediately & effortlessly with every PZD tune, so it is something inside the PRB)
