MAP manipulations

[xxalexx at ix.netcom.com]

I tried a simple 5V level shifter for a Bosch LH for a few minutes 
using a PIC 73 with 10 bit PWM output seemed to work ok.
Also made 3 for L jet for German emissions conversions.
They modified air meter output. used a 16 pt ram offset table
based on input.
