My 02 SSEi L67 has a AFH50M-05 (A2423)

My 95 SSE L36 has a AFH50M-03A (4Y24): willwren said this is the wrong MAF for my car but it was in it when I bought it used and the used trottle body I bought on ebay from a 95 SSE also has the same sensor in it. I am curios if anyone else with the same year/model has this sensor in theirs.

I'd get you the one from the 89, but that has a maf from an unknown year LeSabre, coulda been anywhere from an 88-90, so I can't really report there.

But the 93 has an AFH50M-02E

Both cars 03A. 95'* is original (L67) and IIRC, the 93'* is from a 94 L67.

Thanks alot guys! I still need numbers from 2000-up L36'*. But the mystery appears to lie in the '96 year for both engine trims. Though I can guess they will use the -04 cals.

I also need 92 and 95 L27 cals.

Just from the chart I have put together, the trend is change whenever a PCM format change is made. 94/95 MAFs are specific to only those years, and the 96-98 MAFs as well (at least that is the trend that they appear to take as I am missing the 96 models). 99 on up all use the same MAF.

Once I get a few more numbers available and inputted, I'll post the chart.

On the idea that SC should be different than NA, that'* actually handled in the programming. They could have used nearly the same sensor for every year if they were happy with the design and the setup wouldn't outflow the high end of the sensors ability.

I've got almost all the info needed. Just need 1992 and 1995 L27 cals (I know 95 L27s werent used in the Bonnies but they were used in other models). As soon as I get those, I'll post a screenshot of the spreadsheet.
