MCM numbers

[wjgraz]

OK, probably a dumb question, but what's the difference between a 1K000-phm-050 and a 1K000-phm-030 unit? I have a 2000 model that I replaced the unit on the other day and in putting the old one back in the box I noticed the different number. And how would it affect the performance of the car?

Interesting, I've never seen a 050 revision MCM.

It's just a later revision; they started at 010 and 070 is the current latest.

You might notice some reduced fuel economy.

I think I have a spare 030 around if you want to trade for the 050 when you come down.

I looked and nobody on the list has a 050 unit.

Definitely a hit on the old mpg's. If you have the spare, I'd like to swap it out when I come down. Thanks Eli.
