I've not been focused on tuning like I should be and the last thing I remember doing to the bin was upping the spark table a little bit.
My gas mileage seems to have dropped, but I can't be for sure and one thing is that I am frustrated as it seems like the more I look at the gas gauge, the faster it moves to the empty side.
In any case, I drove to a friends house to look at some old radio equipment and logged that drive to and from.
The altitude where I live is 2750 feet. His place is about 3300.
When I went to leave, I let the truck idle for a few minutes to show him the TBI system and laptop monitoring it.
Logs are attached.
Why was the truck idling at his place so lean?
to his house is the "to eds" and back home is the other.
