adding a 0-100 kpa to the $60??
i was reading some stuff for the 7749, and was thinking
since we have the code for $60(thanks grumpy), why not make it more like the $8D for none boost areas. <~96 kpa.
0 - ?(96 or 100) kpa VE table maybe
i would but w/ school and learning the asm for the 60 code. it would take years for me

The 7749 code only uses the 2 bar MAP for the following tables:
Main Spark,
Premium Fuel Spark,
Boost Multiplier for Fuel,
Cold Engine A/F Ratio
When the 2 bar option isn't selected, the 1 bar MAP is used instead. I haven't confirmed this personally. But, I believe the resolution of these tables is "doubled" when using the 1 bar sensor. So, instead of a MAP axis of 0, 10, 20, 30... you'll get an axis of 0, 5, 10, 15, 20, 25, 30...
So, if I read your post correctly, the ECM already does what you want it to do....?
