The dynojet piggy back units such as PC-v are quicker to tune because you can apply changes to fuel tables while the bike is running on the dyno. There is no need to shut down the engine because you are working with the signal created by the PC, not the ECM directly. All flash style tuners (tts, sert,sepst, direct link) need to be shut down and the altered map be applied. So the answer is yes it takes longer to tune the flash style units, how much longer depends on how close the starting map the operator has to your combination. As for the auto-tune pro on the Powervision, it allows you to set a/f that cannot accurately be obtained with narrow band (stock) O2 sensors. Any KPa ranges from 80 percent and above should be tuned with wideband sensors. The pro system does allow you to monitor a/f while riding and logging.
