I did notice the same thing - that it goes all red at about 120km/h, I don't mind the feature but it would be nice as an option.
Yes you're absolutely right this is a safety / efficiency threshold. As you've said, most cars start to become very inefficient above 75MPH due to wind drag.
We tried to have a "one size fits all" solution however having a simple option to turn the threshold off sounds like a great idea. We will add it to the list.
Thanks for your feedback!
This would be great! I have a frequent route where previous experience has shown that optimal gas mileage is around 78 mph in a hilly section. It was funny that GoFar was all blue going uphill at about 73mph with light application of throttle (~2500 rpm), but went all red after crest of hill as soon as it passed 75 mph and engine down around 1000 rpm (and only 4 cylinders activated, out of 8).
Are any of you guys in the beta test group?
If so, have you had a chance to try out the adjustable speed / safety threshold?
Great Ian, keep those feature requests coming!
