these 2 can comunicate with tech 2

but there will be a third which will be a Mid Speed.. this is what tech 2 can no communicate with regardless of candi fitted or not... i guess it was easier for them to release a new module that would be future proof and also alow them to create laptop based software to go with their GM Global Web based software


just found out the gm tech 2 with candi will still communicate with the major modules of the 2010 camaro,, just tried it on my car and it worked great,,, this is awsome because the gm GDS software with the mdi is very glitchy

just build the vehicle as a 2009 pontiac G8 LS3 auto.
