Pro-m MAF calibration code = 30C ???

  1. I just picked up a (supposedly) new 75mm Pro-M MAF for 94-95 (flanged, black plastic - not chrome) calibrated for 30 lb. injectors on ebay. The calibration code says 30C. Is normal? Does this mean something special? Will this not work correctly?

    I've attached a pic of the calibration sheet that came with this. The printout lists the calibration (circled) as 30 and the 'C' is written in with a pen. The MAF has 30C engraved into it. Does Pro-M supply this data, or is this from someone else? The sheet is dated 30 Jul 2001.

    What's up with this??

  2. I think the C stands for Cold Air Intake. It was calibrated for an engine with CAI.
  3. My Pro-M 77 is for 19s...It has 19C vibro'd on it..your ok...
