Just a random question. Since my tech 2 was lifted from my car last night, I am looki g to replace it. I work on other cars ither then saab and would like the ability to function with both. The tech 2 is the factory tool for saab/gm, the MDI II is gm's replacement for the tech 2. The MDI 2 is backwards compatible to 97. So will this function the same as a tech 2 or is a tech 2 still needed. The mdi 2 was also built after saab was already sold to nevs. The software that I am seeing for it dont say anything about saab, but supports opel. Any thoughts on this?
