Would appreciate the update on the map sensor. A 4-wire plug and play would be awesome. I was looking at the option of using a 2002 WRX MAP sensor since it has an integrated IAT, but there seems to be no proof if it works for EJ251's.Yea I would have liked to try it but didn’t have a part number at the time. Plus I get a sweet discount on Bosch stuff sometimes.
If I cannot get teh 4 bar sensor to work properly I am looking at this 20-300kPa bosch sensor:
Boost Pressure Sensor 0281002437 - Bosch Auto Shop
This place also seems very good for specs: MKS Autobusiness, special components for special needs - Products
I compiled some MAP sensor data. The Subaru values are taken directly from the ROMs for the respective cars. GM data is calculated from the Delphi engineering datasheets (09350899 for 2 bar, 12223861 for 3 bar). It looks like all GM 2 bar sensors use the same calibration but I can't confirm. Let me know your part number and I'll try to find the data for you.

Going to answer myself here.Out of curiosity, what temperature do you guys have for the "Closed Loop - Minimum Coolant Temperature" under the O2 sensors. I have a feeling that's what is causing my issues during cold start (IE starts fine, but within 5 seconds the car starts pulling fuel to get back to 14.7).
Basically on a stock ECU, what is the coolant temp threshold for open to closed loop transition?
USB bluetooth dongles are less than $10. The EMU works okay but I wouldn't buy it again.what are people using to data log?
Im also looking at Emanage Ultimate and now seeing this im not sure what to do.I have a 01 RS and building a EJ22t block/EJ251 heads with turbo, which would be better?
Any chance this will get launch control?
How do you work Bluetooth with a laptop that dont have it?
