First time reading my ecu, everything checked out until I ran it with me7check and got 1 error:

Any help would be fantastic. Thank you.

What does ME7Sum say?

It probably isn't stock.

Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '40/1/ME7.1/5/6005.01//22m/DstD1o/110700//'
 Part Number : '8D0907551L  '

Upload the file. I absolve you of any guilt if it is not stock :P

haha well thank you. I have been fooling around with everything and have fixed the errors and am now running a stage 1 flash in my AR. Thank you for everything. coming from an n54 world, things are a little more involved on this side of the pond and I need to delve a little more. Thanks again.
