New Performance tire for Rocket 2.5 from Metzeler

Any of these tires help with the terrible speedo error? It doesn't look like HealTech make a speedo healer yet.

No- not the tires, but seems like I remember hearing that you can do something (maybe?) in TuneEcu to correct that. Personally, I don't mind having that extra margin of error.

That is correct. I have adjusted my Speedo so its on the nuts with Tunecu and Google maps GPS.

How did you do that? I just downloaded TuneECU to use the Penner map but haven't done that yet. I'd love to adjust the speedo at the same time. The speedo is driving me crazy.

There is a slider bar that adjusts the speedometer its just compare and adjust to the GPS speed on Google maps when in driving mode It can take a few runs to match them but it's easy peazy.

Can I assume you have an older Rocket and not one of the new generation Rocket 3s? I haven't seen the option to correct the Speedo in tuneecu on my 2022 GT

Yeah the new models aren't as user friendly I guess. I would imagine there has gotta be a way. Do you use Tunecu on a new model?
