$58/$60 better 3bar patch?

im sure this has already been looked @ but if not here goes..

i was looking into interpolating the out put of a 3-bar map to a logger for a friend and came up w/ this.

Calculated M and B:
M = (8.9)
B = (-14.7)

so if you look.

Volts PSI
x = (Volts - B) / M
1 -5.8
2 3.1
3 12
4 20.9
5 29.8


OR

Psi Volts
x = PSI*M+B
1 1.764
2 1.876
3 1.989
4 2.101
5 2.213
14 3.225
15 3.337
20 3.899
25 4.461
28 4.798
29 4.910
30 5.022

its close. so could someone edit/add this into the map code of the $60 for a linear 3-bar patch

The patch is in the archives here, at TGO...
It let's you run the 3 bar sensor, while not perfect it's within a couple percent.
