Allow me to clarify this.
The tune could originally be set for either the on or off switch position. I have mine turned on when the cruise is on - my thinking was that a dealer (back in the days when I still had warranty coverage) might turn a cruise off if he saw the light on, and if they did and then tested the car, they would get some pretty interesting and possibly warranty denying readings.
I had mine set for on=on. Oddly enough, I have seen a couple of people saying that they asked for this option but were told that Trifecta couldn't do it and that the 'on' for the tune had to =off for the cruise, something I know for a fact is not true. No idea why. Maybe they have decided to do them all that way for some reason...
I just purchased a Trifecta budget tune and thought a response to this old post might help someone else now. Firstly let me say the reason I want my tune set to as @wspohn
says, "on=on" is 1, I can leave the cc button on and it stays on after restarting car, so I don't have to press a button every time I start car to get to the tune. And 2, when putting along with cc on I want the option for immediate full power to pass some jerk, pedal to the metal as they say, not first messing around with buttons.
I have verified customers used to have the option to buy it this way.
I have verified Trifecta now says they can not do it.
posts, I pressed Trifecta for an explanation. Steven at Trifecta today responds, "We've posted some updated calibrations to your download page, including one labeled "CC_BACKWARDS". We don't recommend using it, frankly, but its what you asked for. There may be some quirks to power delivery, which is why we stopped offering it years ago."
I will either use the cc on=on or use the always on file I also got from Trifecta. Just wondering if wspohn or anyone else with the old on=on option can report some detail on power delivery quirks they've experienced.
And it brings to mind a more general question, like if someone has gotten the competition mode = on option, or the always on option, is the cruise control operation messed up when using with the tuned mode? More jerky cc? Or other problems I should be alert for? Basically I'm a little mystified if cc works as normal with the always on tune, but Trifecta reports quirky with cc on=on. Perhaps a result of a software bug, not a necessary logical characteristic? Anyone?
