Hey guys, before you bury me simply based on the subject, check this out:

I've stfa for days now, read all the chip mbox chbox posts, and I'm quite aware of the compatibility with chboxes and mboxes, but I've got a new question.

I have a 2001 1.8tqm w/ stock mbox.

I also have a apr 93 octane chip (chip only) that was pulled/desoldered from a '01 chbox. This chip is the ECMS 1 version and not the ECMS 2.

According to the pics from APR's site, see following posts, it looks as if only the ECMS 2 style chip is on the mbox whereas the ECMS 1 is on the chbox.

Is anyone familiar with these circuit board chip nuances. Will my ECMS 1 chip work on my mbox? And no, I won't be soldering myself. Just thought I'd get my facts straight before going to local APR tuner for soldering.<ul><li><a href="http://goapr.com/Audi/support/emcs_version_upgrade.html">Link to instructions for ECMS programming pdf</a></li></ul>

link to pics from APR pdf on ECMS programming. It appears that chbox has ECMS 1 and mbox has ECMS 2<ul><li><a href="http://www.flickr.com/photos/chadfoley/">link to pictures</a></li></ul>

Mr. Head

My understanding is that M box and CH boxes are directly compatible...

yes I know, but are ECMS 1 and 2 chips compatible with either box?

In other words, can you solder an ECMS 1 chip from a chbox on to a mbox?

The pins line up fine.

See link for difference between ECMS 1 and 2.<ul><li><a href="http://goapr.com/Audi/support/emcs_version_upgrade.html">ECMS 1 vs. ECMS 2</a></li></ul>

is simply in the connector style and has nothing to do with the software or ECU version. The board connector on 1 is now the cable connector on 2 and vice versa. If you buy the EMCS programmer, you can also buy the different adapters to use on any of the board versions.
