Nissan 200SX Club - South Africa

part number is 22680 31u00 A36-608 e60

That's a J30 MAF, also called a E60. Off a MAxima QX, RB20DET or early RB25DET

All N60/N62's have 5 wire plugs, not 3 wires like yours.

It will still work. Good for around 350hp max. Not as big as the N-series MAF's, but okay for that price. Just not sure of how much of an upgrade it is.

Thing with all these bigger, newer maf's are that they are more stable to tune at high HP.

Whats a MAF exactly????

LOL - google.

its a Mass Air Flow sensor

it's when you wanna make your lady friend very very happy, or if you've done something wrong....

Haha Doc G, its like AFM????

It’s a Mass Air flow meter , Using Temperature and a hot-wire sensor it can determine the “mass” of air entering the system and supply fuel accordingly, If you look in you engine bay it’s the silver object attached to you air box..

Ok poizen, I will be dead honest with you about you options, First off to fit that MAF you will need cut your harness also you will need to chip your ECU, you can have a chip custom made up and shipped to by a company on Ebay called Speedlab I talk to guy a lot on the tuning forums he knows his stuff and my first tune was done by him.

OR

You could sell the AFM and buy the Gotec\Mr Turbo what u ma call it being sold in the classified section and switch over to a MAP load sensor.

OR

Buy the Nistune system from (www.nistune.co.za) costs around R 2800 shipped and I will help you tune the system

OR

just sell the MAF for a profit and buy a intercooler or something

niztune dude...

its worth it - i'm told!

ok ill let it go for 600 anyone interested

ok ill let it go for 600 anyone interested

I think you are going to have to go lower then that


I have had my spare Maxima Q \ Pathfinder MAF for sale for almost 6 months at R300

I cant see pic's but if it a N62 it will be gone in no time

as the good doctor told me MAF=AFM

just different naming conventions!

Nope, they are 2 totally different types of sensors and their names say, one measures mass and one measures flow.

Okay so seems AFM is a type of MAF.

MAF try's to measures density (but can't do it by itself, so needs extra sensors) and AFM measures flow.

From wiki:

An air flow meter is used in some cars to measure the quantity of air going to the engine. All modern electronically controlled Diesel engines use air flow meter as it is the only possible means of determining the air intake for them. In the case of a gasoline engine the electronic control unit then calculates how much fuel is needed to inject into the cylinder ports. In the diesel engine the ecu meters the fuel through the injectors into the engines cylinders during the compression stroke.

The vane (flap) type air flow meters (Bosch L-Jetronic and early Motronic EFI systems) actually measure air volume, whereas the later "hot wire" and "hot film" air flow meters measure speed of air flow.

The flap type meter includes a spring which returns the internal flap to the initial position. Sometimes if the spring is tensioned too tight, it can cause restrict the incoming air and it would cause the intake air speed to increase when not opened fully.

A mass airflow sensor is used to find out the mass of air entering a fuel-injected engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the ambient temperature and altitude, and this is an ideal application for a mass sensor. (See stoichiometry and ideal gas law.)

There are two common types of mass airflow sensors in usage on gasoline engines. These are the vane meter and the hot wire. Neither design employs technology that measures air mass directly. However, with an additional sensor or two, the engine's air mass flow rate can be accurately determined.

Both approaches are used almost exclusively on electronic fuel injection (EFI) engines. Both sensor designs output a 0 - 5.0 volt signal that is proportional to the air mass flow rate, and both sensors have an intake air temperature (IAT) sensor incorporated into their housings.

When a MAF is used in conjunction with an oxygen sensor, the engine's air/fuel ratio can be controlled very accurately. The MAF sensor provides the open-loop predicted air flow information (the measured air flow) to the ECU, and the oxygen sensor provides closed-loop feedback in order to make minor corrections to the predicted air mass.
