Ok my new OBD bosch 1300 scanner came in today. I was doing sone live data and found the MAF readings to be like 2,000. I unplugged the NAF and the readings were at 3,000?

i thought it should be around 7-12 at the most at idle?

do you think the MAF is bad? Im not sure what the relays do but i assume they work since the readings are changing? See below pic for maf reading right under loop statis

thanks guys!

Something is wrong with the scan tool translation of the data. MAF can't exceed 255 grams per second. It's an 8 bit value.

I think they likely have never tested it with some old 80's ALDL protocol and have copy and pasted themselves into a bug in the scan tool firmware. Check with Bosch for firmware updates.
