1 Bar = 14.7 PSI right?
2 Bar = 29.4 then?
So why 17 PSI? I know that is the limit of the stock (actually thought it was around 15 but havent tuned enough to get up there yet - still having boost control problems at 14).
So why 17?

A 2-bar sensor is technically only good to 14.5 psi ABOVE atmosphere (which is nominally 14.7 psi). However, the Mazda sensor is good til about 17 psi ABOVE atmosphere (safety factor and all that).

Here is what needs to be changed with the datalogit
Hope this makes sense:
GM 3 BAR MAP Sensor Part Numbers:
16040749 – sensor (71130)
12085502 – connector (71121)
GM 3bar // Function // Rx7 Factory Wiring
A // GRND // Black/Grey
B // MAP SENSOR VOLTS // Greeen/Yellow
C // 5V // Brown/White
PFC MAP Sensor Settings:
scale: 41800
offset: 0

I saw your note on GM boost sensor in an old post. Question - Can I replace my stock 93 rx7 boost sensor with this new GM sensor, wire it correctly and still ahve the stock ECU run correctly ? I am suspecting I have a bad sensor, getting code 13. I have the PMC along with the stock ECU for now. What do you think ?

We have checked against VW turbo models (inc. RS4), Subaru's, Mitsi's, etc etc. but with no luck. Once we know what car has them as standard, Denso can supply us them.
