Hey you! Come analyze my fuel map.
Seems to be working pretty good so far. I got 24 mpg's on my last tank so I made a few changes this morning to improve things. I would like to get some of you MS smart guys to look at it and see if anything jumps out at you.
Thanks Gents!

Lots of things are weird. Whats really weird is when I calculate my reguired fuel for 14.7 afr it tell me 4.9. I dont know what that means but the car seems to be doing just fine with 6.5. Is there any reason I should put 4.9 and then retune my map? As is if I put 4.9 it leans out like crazy.

I recall that in the MS documentation, it says that you should not modify the required fuel, from its default setting. This default for 550 injectors, and 1839cc engine is 5.6. I don't know what happens if this number is set differently.
you really can't compare individual bins in your VE table to other people's table. The tolerances in the sensors can really stack up.
With my MS, if the Bar. pressure happens to be 101, my map sensor reads 94.(measured with engine not running) I presume some MS units could be high by that same amount, causing the VE tables to look different even if the engine tunes were exactly the same.
I think you can however, compare the percentage change in a group of bins, to a group of bins on another install.
