Chip, I don't have any flag to wave on here, we do next-to-no Ford mapping.

You can't map inbetween the cells, all you can do is take into account how the ECU interpolates and map the values of the cells accordingly. Thats what I was getting at.

Compared to being able to do neither on the road. You certainly can't hit a cell accurately, let alone consider interpolation.

All that said, VERY detailed and faultless mapping takes OEM months with teams of mappers, so it's all a comprimise anyway to suggest you can do the same in one day (or in the case of most tuner alot less).

We spend alot more time than most on the off-boost mapping and achieve good driveability. We usually keep a car thats having a full-map for 2 days at least so that we can check it right through the heat cycle too. Remember I get to see alot of maps and compare them to standard default maps and it never ceases to amaze me how many so-called tuners do nothing to the map other than idle and full power.
