Hey guys, I spoke with Innovate Motorsports about getting the info needed for the MTX-L wideband serial support. They gave me these 2 links below. I emailed HP Tuners support, and they told me to post the info here, so here it is:
Serial Protocol 2: http://www.innovatemotorsports.com/s...eriallog-2.pdf
OT-2 SDK Manual:

Supposedly that is all the info you guys should need. Hope it helps!
