4g63 MAF problem

[sempron555]

Hello, am new in the fórum. I got a Mitsubishi ZX from 1993 is like a old Galant with 4g63 engine non turbo. Some days ago my MAF just wont work anymore and where I live can't find a replacement. Is there any other MAF that I can plug and play with just changing the wires? As you can see the connector only has 5 pins. Thanks for your time

I'm on a GM MAF, wasn't plug n play because of the n/t MAF connector but I made it work.

Great thanks! Btw will they work with just changing the conector and wires? or i will need to tune or something?

When going from a 1g MAF to 2g MAF, because the 2g version flows more air, you'll either need a way to tune the car or you have to install larger injectors. The size of the injectors will differ based on what size is currently in the car. I don't know what came in the '93 ZX.

thanks for the reply! stock inyectors are 240 but currently am using 265 wll that do the trick?

I don't believe so. From what I've read, the 2g MAF flows roughly 20% more air so you would need roughly 20% more fuel. Stock 1g manual turbo injectors are 450cc so you swap in 550cc injectors to compensate.

That's just how it is with the 4g63t cars. I'm not saying it will necessarily work on yours. You would probably be better off just finding a direct replacement in a junkyard or eBay.

Going either route would be about the same process.

Switching to a GM MAF was the most suitable choice for my application. My n/t MAF was cutting out,and I'm in the process of going turbo, so I found switching to a GM MAF would get me by until switching to Link and SD.

If your looking for something closer to stock use I'd recommend a 2g MAF. If I'm not mistaken, you retain a few more sensor than you would if going with a GM MAF and Translator.

Either way you'd need to find a way to tell the computer you put in bigger injectors if that's the route you go. My setup starts to break up a bit in the higher gears over 5k if it gets over 100 degrees ambient temperature. Anything below that I've got tuned pretty smooth on black 450's.

Alrighty am gonna keep trying to find the stock one if not i will have to go with the 2g and change the inyectors.. thanks a lot for all the help guys!
