Evo-all 2006 Audi A3 with CM7200 controller not seeing tach through Data

Question

I am installing a cm7200 starer in a 2003 Audi A3 and am using the data port for connectiong the two units. I cannot find if there are any issues with compatibility between these two units IE, two way data. I can't seem to get tach to program or the unit to go into reservation mode for standards. i am guessing the reservation issue is something to do with the tach issue.

Answer 1

Leave your compustar in the default data protocol and set your evoall to AP/OFA datalink.

Or try to hardwire the tach between EVOALL and your cm7200.
