you could always go with a different MAP sensor... like a GM 2bar or 3bar. those conversion tables are widely known and available.
i used to have one, but did not like that the GM MAP sensors are not linear with respect to voltage and pressure conversion. i did find this motorola one that is linear.. was only about $20, and goes to 20psi. you need to build a project box for it, including a regulated 5v power supply (unless you tap for 5v from the ecu). works out great...
let me know if you want more information.

Actually, I figured out a solution. THere is alos a psi-kPA conversion I could use. I think its like 1psi = 6.8kpa
I'll try that and see if it works. I'd rather not buy anything else, since the Greddy sensor is already a really good quality 2 bar MAP sensor.
