Guy's listing these MAF's on ebay buy it now for 299.95

hopefully most of you are smart enough to check, but the same part from advance auto is 169.99. If it works, another alternative like the wells su145?

Oh and the advance auto says lifetime warranty, not 30 days like this guy.

 

What is unique about that MAF if that it is adjustable. You won't have to reprogram your maf tables if you make changes to your intake/heads/cam. I have one and it works great.

 

I'm not arguing that, just the price, the one i got from advance is exactly the same, same part number on the side etc etc. Mine works great too. But mine cost 169.95, not 299.95.

I'd argue adjusting the maf vs getting your prom set up right though. Kinda like tuning via fuel pressure. Sure you can get close and get some good results, but it's not gonna be perfect all across the board.

 

an adjustible maf sensor!? I have never heard of that, if anyone can explain how it works that would be cool.

 

That may resolve the problem of the ECM not being able to read anything over 255grams/sec from the MAF. Has anyone looked into this? My thought is that you could adjust the MAF to read less airflow, and then either raise the fuel pressure or install larger injectors. The computer wouldn't know the difference, but you would stay below the 255 g/s limitation of the 8-bit ECM and flow more fuel. This is what the Ford guys have been doing for years.

 

I would like to know also. Can you adjust the max grams ingested, or what? Hwo do you adjust it?

 

with a hammer! that'll adjust it good!

 

With this MAF, you adjust the voltage out from the MAF to the ECU. This lies to the ECU reguarding the air grams/sec coming into the engine, which then changes the load calculation that the ECU "sees", and alters fuel/spark accordingly.

What you need to do for a properly adjusted MAF is change the sampling rate with a larger sampling tube (or differently shaped one) and increase the resolution in the chip. Electrically adjusting the MAF is a bandaid fix, just like AFPR's on a stock chip.
