The GM Tech 2 has been around since the 1980’s. It has been the flagship diagnostic tool and programing device for many many years. it continues to be a valuable part of the GM dealership stable because its quick, efficient, and works great! Now that other diagnostic programs that are, for the most part, only economically viable for GM dealership technicians to use (like Tech2WIN) the cost of Tech 2 has come down a little bit over years past. It is because the Tech 2 has been around for as long as it has that it is such a copied and cloned unit.
GM Tech 2 is used on obd2 GM vehicles which mainly built from 1992 to 2011, while GM MDI supports vehicles from 1990 up to 2013. Now every vehicle for now on will be using GDS with the GM MDI Scan tool that is why we said MDI is replacing the tech 2. However, Tech2 works with quite well with some SAAB cars due to its SAAB card, while a few SAAB owners said MDI not support their cars.
You do not need to divorce any module. You just enter your VIN when you get to that screen on the Tech2.Think about it this way, if the ECU was completely fried it could still be replaced with a new one. The old (any old module – not just ECU) needs to be removed via Tech 2 from the car that is getting a replacement module. The donor car does not matter at all. Then the replacement module gets added to the car via Tech 2 needing a replacement module. The module may need SPS programming to load the correct version of software based on Engine, Market and other options depending on the module.
