Here in Ontario Canada weve had -30 to -45 Celcius weather lately.
After scaling injectors ( double AFR , halve IFR ) I am having massive fueling issue with cold starts. If the truck sits for any length of time ( even 45 to an hour ) it doesn't want to start. Im assuming that doubling the AFR has caused this issue . Would cutting the open loop fueling in half fix this ?
