Enjoy

Thank You...hmmm. .. there is really no easy way to say this but..... How about some documentation of our engine ECU 'Torque management' ? Have you looked at or read that ? i guess not... Maybe you could enjoy that See below the table of content.

You guys are answering a highly technical question with marketing prospectus level answers (which i have those too, off course).
