Does anyone here realise that when your car is on the dyno being flashed tuned, a large amount of time (hence money) is spent flashing the ecu? I can take half and hour to try something doing a flashes that can be done in 5 minutes in real time.
Not having to continually stop, save, reflash, restart is a MASSIVE advantage.

Yeah I often forget how painful it is to sit and wait to flash an ECU... GTRs used to be horrible. You can definitely get much more done in a 2 hour tuning session when things are adjustable real time for sure.
The Hydra allows real time tuning and no download is required at all. This is really nice as it allows the tuner to drive on the dyno and easily work out any kinks in a particular spot, like cruise areas. I often use this strategy while I'm tuning the cams for cruise, which won't show up on a power pull.
There is also an "Autotune" feature so if you have a load hold feature on the dyno the Hydra will use the WB Target AFR Table and compare it to real time AFRs and make changes to the actual fuel map.
