I recently moved from Tucson AZ where it was in the 80s to minot ND where it has gotten down to -10*f. It was running very rich so I did some logging and updated the ve table. Every time I go from park to gear the rpms drop very low and sometimes dies. What else do I need to change? I've tried to do the rafig but I'm at a loss on that one
Andy,
If it was dialled in well before, and is out everywhere, you could try putting the VE tabl eback the way it was and using the IAT VE Multiplier {A0014}.
Chances are, this table up it's still set to 1.000 at the IATs you're currently seeing.
Yes. The ve was pretty much perfect before the move. But the atmosphere was around 89kpa there so that's how I had my tune set up. It's 96kpa here so it was actually commanding 13.5 afr at cruise. And I also had to adjust the timing as it was only commanding 20* at cruise. Only issue now is where it sometimes stalls when I put it into gear.
Okay, in the mornings before I leave for work I will use the remote start to warm up the truck. By the time I get in to leave the coolant is around 160-170*F. And afr will be around 16.5-17. When I put it in gear afr will go to 15.5 which is what I'm commanding. Would this be to much in the desired airflow table?
