C.A.T.S. RT Tuner 2.1

The C.A.T.S. RT Tuner was developed to allow ‘real-time’ ECM tuning when connected to the Xtronics Romulator or the Craig Moates Ostrich or AutoProm EPROM emulators. With the EPROM Emulator replacing the ECMs original EPROM, you can make calibration changes while the engine is running and the changes will take affect immediately. No longer do you need to make a change, program an EPROM and install it in the ECM to test your calibration changes.
