Motorola 4 Bar Map Question

So I finally put a Motorola 4 bar on. Using Hondata help section I have caculated the Scalar at 826 and the offset at 162.

It Runs on .2 to 4.8 volts
and 20 to 400 kpa

Now the car runs real rich.... Did I do something wrong?

If anyone can comment before I retune the whole map that would be great. I expected with correct values for scalar and offset I wouldn't have to change anything on the maps? If that information was correct.

Thanks

I used that its fine... the numbers I got from the pdf... and put into the formulas didn't work.... I adjusted and finally did end up using their hondata numbers.
