I've still got my car on jackstands for a LICP and HFC, so I haven't tried to start the car yet. I may install the sensor tomorrow and turn on the ignition just to see if the ecu throws a code with the engine off but ignition on.
Since I havent heard anything about this, I decided to experiment with a GM 3 bar sensor and should have some documentation on it by the end of the week.
Buschur sells a special fitting that bolts in place of the stock sensor, so I will try doing that instead. It makes sense in my case because If it works, its one less issue to deal with on my aftermarket intake manifold when I install it.

thanks
josh hit me up on pm. thanks again
Ive been able to log with a GM 3 bar sensor instead of the stock sensor. Unfortunately you have to disconnect both of the vacuum lines to the EGR valve (and plug them) since they also hook up to several other places. The other problem (On the USDM cars for certain, the others I'm not sure) is you will throw different EGR codes and not complete the EGR Test sucessfully (which would be an inspection/obd-ii issue) So I'm not currently using the sensor. I have to assume that the JDM sensor would work the same way.
So, in order to do this, the ECU would need some modification to not throw those codes or you would have to change the calibration table for EGR function (which I don't know where it is, or if it even exists)
The sensor itself does read through MUT and would only need to use the right calibration. (JDM is easier since the calibration is already known)

Jack,
Do you have the calibration #s between boost and RAW voltage value for the GM sensor? I'm going to use a GM MAP sensor to log boost and wire it through the stock MAP sensor port. Thanks!

No I've just verified it works, I have to take a bit of time to match the digital output to boost level as I already have a GM map sensor installed in the car running to my UTEC/ECU+ (whichever I'm testing at the time) so I already know what its reading.
The GM Map sensor mod through the MAP sensor port mod has the done many times on 2g DSMs and logged w/ DSMLink. I'll shoot the DSMLink guys an email to ask what the calc routine is for the GM sensor.
Which 3bar do you have? Part # wise, may be able to help ya get a voltage vs psi table.
