I recently noticed that it seems like several people with auto-tuners on their bikes still end up going to a dyno to get things just right. I also wondered why there are no mass air flow sensors on any of these auto-tuners. Am I the only one that has wondered this? Why no air flow sensors? It seems like with the addition of an air flow sensor of one kind or another, more variables would be able to be sampled by the auto-tuner and therefore a better tune would result. Or I could just be an idiot.
I am not a technical expert at all. But my bike is a 2005 which did not have O2 sensors. I installed a DTT when I did my HQ build. I had to add O2 sensors to my pipes. With the DTT you have to use O2 sensors.
I have never heard anyone with the DTT going to a dyno to get things right. We go to see our HP/TQ numbers.

I agree. I only put it on a dyno to ensure the A/F ratio was correct and to see what the numbers were.
