Lincoln 80mm MAF made in Japan? Tweecer related

[MySHOcanGo]

Here's a pic of my maf, took it out to clean it because the low end stumble that started a couple weeks ago is getting worse. This is when I noticed that the MAF was made in Japan. Can anyone confirm this is indeed an 80mm Lincoln MAS? I just want to make sure I have the right MAF transfer values loaded on the tweecer.

Kinda big pic:

Any chance you could post a clear shot of the (black) sensor package, with the part number showing as viewed from the top? The MAF in the picture that you posted looks like an 80mm to me; however, the electronics package is what's really important when it comes to determining what MAF you have and which curve to use.

Here the top of sensor.

Yes, sir - what you have is, without a doubt, a Lincoln Mark VIII 80mm MAF.

Two quick unrelated Q's if I may, though:

- what did you use to clean the hotwire sensor elements with?

- which transfer function (curve) are you using in your TwEECer program?

Thanks ax. I used some contact cleaner to clean the elements. And I'm this (http://hosting.superhighoutput.com/axianator/za0_80mm.maf)for the transfer curve. I believe you posted it on another thread.

I'm still getting some low(er) RPM stumbling so it wasnt the MAF being dirty (fouled). I'm thinking its probably fuel filter or plug wire related.
