Thats where id like to see what i can figure out. i have Gm's software, MDI2 and their SPS which allows me to flash in their factory calibrations since 2001-2005 chevy/suzuki produced the "tracker". if they can do it through the OBD2 plug, i know we can :)
just saying hi and looking into how i can get into, tune, and flash my 33920-67D33 ecm for 2000 suzuki grand vitara 2.5 4 speed auto. Currently have a piggy back AEM module for a turbo setup ill be putting on but its not playing nice and id much rather get into the stock ecm.
