Hey guys, I just purchased a '02 Z06 with STS twin turbos and HP tuners. I just updated the software to the newest version 2.1.12. The car had 2 credits left and was still on 1-bar MAF set-up, so I upgraded it to the 2-bar SD set-up and did a 'write entire', and the RTT is no where to be found. I searched the forums and noticed when other people upgrade and click the 'OS' button that pops up the options to purchase (1-bar maf enhanced, 2-bar sd, 3-bar sd, etc) it says 'RTT' beside each option, but mine did not.
I do not even want to think about tuning this thing without real time tuning, can someone please point out what I'm doing wrong or what updates/etc I'm lacking to make the RTT appear. Or, does the Z06 VCM/ECU not have enough free RAM to tune 2-bar and RTT together? Thanks guys!!
