For a 2002 GM vehicle.
Which system do i buy?
1- Want to log a WB O2 sensor
2- Want the VE table to work off of the WB O2 sensor
3- Add Flex fuel sensor if possible
4- Want to log Boost
5- Want to save and load different tunes at different times for whatever reasons.
6- Want to log cranking though start
Also the computer has already been modified by HPtuners -- Do i need to use credits again to use my new Hptuners on it?
Could i save a previously loaded tune on my ECM by someone else on my laptop for back use in case i screw things up and need to go back to that tune?
