I have read a good bit and only confused myself with this. You do increase the BPW number to make the fuel leaner or not? I may have also overlooked a conversion for converting MAP voltage to Kpa as my scanner reads MAP voltage or should I just use the conversion chart for vac to Kpa and write the Kpa's on the face of my vacuum guage?

K/Pa is almost a standard when working with EFI, might as well get accustomed to it.

As far as BPW goes, I look at a few files to get a handle on whats used, and then fudge accordingly. Other disagree and get into the fine details about the math. I'f rather rough it in and then with driving tuning get it dialed in.

Thanks Grumpy. I guess I'll forget map voltage because I need to be watching BLM on the scanner anyway. I'm not wanting to do any math as I've got a good baseline and have been driving it 50 miles a day and just installed a vac guage and so far can tell that it will be a good learning tool. Have been playing with F/P and BPW to lean down everything but still have an overrich idle and lean WOT.
