Hey everyone, I have been doing some research on larger mass air flow sensors and it seems that the older 300zx maf might work. It has the same plug and it uses the burnoff wire like the 87-90 subaru maf. The only thing I am still looking for is the output voltage range on the sensor. If the output range is the same it should work and it is a full centimeter larger in diameter.

 

Does anyone have a manual for the older 300z years 84-89 and I think the 280z have the same maf. Any help would be apritiated.

WOW! If it does work, then we'll have a 300ZX injector upgrade AND a MAF upgrade as well... Sorry I can't help ya out but this is pretty interesting...

air flow meter voltage between terminals B and D

1984 thru 1986 1.6 +/- 0.5v

1987 on 2 to 4v

 

E battery source

B -- output voltage

A -- variable resistor

D -- Ground

F -- Self-cleaning

C Ground

 

-- connects to ECU
