Hey Bob. I know that either the literature we'd gotten or one of the videos we watched on the 2.0 system said it would initially set the efi fat and then lean things out as it learned.
Most of the time that we had the original system working my son had the car in Des Moines so I'm not sure how much it dropped the amount of fuel over time. I do know that each time we rebooted the system it did start out very rich.
I got another call from the shop this morning. It wasn't from the guy working on the car but from the guy running the parts counter. They want me to bring my laptop in so they can use it. I wasn't given the reason why they needed my laptop instead of using their own. I assume they couldn't get the software. I suppose I should buy a thumb drive and put a copy of it on there for them. Then maybe I won't have to leave my laptop with them. I guess I'll take them both to be safe. Monday is the earliest I'll be able to get it to them.
