(eventually this page will have more information)
The main product that we make for 98+ GM vehicles is the RoadRunner emulator that allows realtime changes to be made to a LS1 ECM.
The RoadRunner is designed to be used with either EFI Live or TunerCATS software.
EFI Live is a comprehensive tuning software package that includes both an editor and logging application. The software has the most comprehensive vehicle support out of any package we sell for OBD2 GM, working with both Gen3 and Gen4 ECMs and TCMs. It is licensed on a per-vehicle or per ECM type basis.
Tuner CATS OBD2 tuner is used primarily with the RoadRunner hardware. It only supports Gen3 LS1 ECMs/TCMs. Tuner CATS OBD2 tuner can ONLY BE SOLD WITH ROADRUNNER HARDWARE. WE CANNOT SELL IT TO YOU UNDER ANY CIRCUMSTANCES UNLESS YOU BUY ROADRUNNER HARDWARE. It is licensed on a per ECM type basis.
