trying to convert to 2g mas....question

[Munster000]

I am planning on soldering the wires from the 2g plug straight onto the wires on the car, but on the diagram for vfaq....the 1g has an idle position switch (wire #1) and the 2g has a volume air flow sensor (wire #7).

http://vfaq.com/mods/2GMAF-1G.html

It says they are worded differently in the shop manuals but does that mean those two wires are suppose to go together?

Anything else I should know?

p.s. if I did decide to make an adapter, how do I get the stock plug out of the 1g mas?

Take the mas apart , the plug will come out in one piece .

1G MAF

MAF 1) Green with White: ECU 6 -idle position
MAF 2) Green with Blue: ECU 10 -vafs
MAF 3) Red:+12
MAF 4) Green with Red: ECU 23 - sensor voltage
MAF 5) Not Used
MAF 6) Green with Black: Sensor Gnd
MAF 7) Green with Yellow: ECU 16 -baro
MAF 8 ) Green with Orange: EU 8 - IAT

2G MAF

MAF 1) Green with Yellow: ECU 81 -sensor voltage
MAF 2) Orange: ECU 85 baro
MAF 3) Blue: ECU 90 - vafs
MAF 4) --- +12
MAF 5) Black: sensor ground
MAF 6) Red with Blue: ECU 72 -IAT
MAF 7) Red with White: ECU 19 -vafs reset
MAF 8 ) Blank


Sensor Voltage (+5): Pin 4 1g to Pin 1 2g
Sensor Ground: Pin 6 1g to Pin 5 2g
Baro: Pin 7 1g to Pin 2 2g
IAT: Pin 8 1g to Pin 6 2g
VAFS: Pin 2 1g to Pin 3 2g
+12 MPI: Pin 3 1g to Pin 4 2g
Idle/VAFS-r: Pin 1 1g to Pin 7 2g

Hope this helps.

That answered the question I was gonna post thanks

I'm thinking of doing a 2g mas conversion due to a bad 1g mas. My car is completly stock. What tuning, if any, will be needed and how do i do it?

Either a chip, a afc, 550 injectors, dsmlink, or additional fuel pressure (not really recommended due to tuning difficulty).

Thank you I'll look into it
