2g MAS on a 1g non turbo 4g63
since the 1g forum is dead ill post here
i got a 90 talon non turbo, does the 2g turbo MAS work with those also? or will it fall on its face?
this is a dirt circle track car & it needs less restricted airflow badly, but has to appear stock.
no high dollar stuff, just whatever stock parts we can get away with.

RE: 2g MAS on a 1g non turbo 4g63
Yup, it sure will bro.
Spinz4 has a 2G MAF on his 1G too.
Here's more from the VFAQ..

I wrote this up on wnydsm.org before the shootout but I thought I would share with some more cool dsmers.
Once upon a time there were 1g Mafs....those sucked. Limited to reading airflow to ~30lbs/min.
Next up were the 2g Mafs....much better. Limited to reading airflow to ~52lbs/min.
Finally we have the end all be all Evo Maf. Limited to reading airflow to ~62lbs/min.
62lbs/min generally equals about 600whp. This is more than enough for any DSM still running a Maf after that point I would only recommend a full standalone engine management system using speed density instead of a Maf.
The reasons I decided to run one in my car in replacement of my 3” GM Maf are: Better airflow readings, easier to tune and the air temperature sensor and barometric sensors are still used.
The Evo 8 Maf is an almost direct swap for the 2g! All the pins are the same, but the connector is different and the sensor outlet to the intake pipe is round not oval.
You will either need the connector from the Evo your Maf came from or you can use the connector from 01-04 Chrysler Sebring (Cpe), 01-04 Dodge Stratus (Cpe), 00-02 Mitsubishi Eclipse, 03-04 Mitsubishi eclipse exc. GTS, 99-03 Mitsubishi Montero Sport 3.0L, 2003 Mitsubishi Outlander, 99-03 Mitsubishi Galant. Just cut one wire at a time from the stock 2g harness and splice it accordingly to the same pin of the new connector.
The wiring for the Evo connector:
Pin 1: gray wire - Connects to ECU pin 81, which is a 5V source and goes to the volume air sensor's atmospheric pressure sensor.
Pin 2: yellow/blue stripe wire - Connects to ECU pin 85, which appears to be a sink (sort of like a ground for solid state devices). Appears to be the ground for the volume air sensor's atmospheric pressure sensor.
Pin 3: white/red stripe wire - Connects to ECU pin 90. This is a signal pull-up line. Appears to be the actual atmospheric pressure sensor signal to the ECU.
Pin 4: red/yellow stripe wire - MFI relay. This appears to be the main 12V power from the battery when the relay is energized.
Pin 5: black wire - Chassis ground through ECU pin 40.
Pin 6: red/blue stripe wire - Connects to ECU pin 72, which is a 5V voltage source for the intake air temperature sensor in the Maf.
Pin 7: blue/black stripe wire - Connects to ECU pin 19.
The wiring for the 2g connector:
Pin 1: gray / yellow stripe wire - Connects to ECU pin 81.
Pin 2: orange wire - Connects to ECU pin 85.
Pin 3: blue / yellow stripe wire - Connects to ECU pin 90.
Pin 4: red wire - Connects to the MFI relay, cam shaft position sensor, crankshaft position sensor, idle air control motor, and both oxygen sensors. This appears to be the main 12V power from the battery when the relay is energized. This is slightly different from the Evo circuitry because Mitsubishi was still running lots of sensors off the same power source.
Pin 5: black wire - Chassis ground through ECU pin 92. Also goes to the fuel tank differential pressure sensor, the manifold differential pressure sensor, throttle position sensor, engine coolant temperature switch, and both oxygen sensors. This is slightly different from the Evo circuitry because Mitsubishi was still running lots of sensors off the same ground lead.
Pin 6: red / blue stripe wire - Connects to ECU pin 72.
Pin 7: blue/black stripe wire - Connects to ECU pin 19.
Pin 8: Empty - Unused
