GM map sensor calibrations #257

I am not sure our GM default calibrations are correct, the 3 bar we had was 10kpa out at ambient on the dyno.

Using the calibrations below corrected it.

The numbers we have in the firmware (for the 3 bar, at least) agree exactly with this: https://www.bmotorsports.com/shop/product_info.php/cPath/0_129_143/products_id/1584

hmmm, 2 competing calibrations for what should be the same sensor, both correct in the context of their specific product.

Put this one on the back burner and I will look into why these 2 versions of the same sensor differ. No wonder people complain about the variability/reliability of these GM sensors.
