Re: DIS for GMECM

[Speartech <speartec@iquest.net>]

The special cover is marine part.  If I had some MEFI2 info I would share 
it. I do have the complete schematic of the controller including the 
optional inputs (like O2 sensor), that were never activated in the 
software. But I'm guessing you're after programming info, which I don't have.
