    RPM running backwards

    I just updated my firmware and now my rpms are running backwards, that is, the faster the engine goes, the lower the rpms drop. Seems like a simple fix. Anyone else having this issue? Thoughts about how to fix it?

    FYI I called the help line and talked to a tech and he said that it's an issue with the app itself and he wanted me to email him a video clip of the issue happening which I haven't yet because he gave me the wrong email, it ended up bouncing back so I emailed the main support email address. Haven't heard anything yet. Hopefully soon. He didn't think there was a fix yet for this issue. Bummer.

    I emailed support and described the problem. They emailed back and asked for more details. After I answered, they responded with this "Thanks for the information. The issue should be corrected in the next app update."

    Hi im new member here.
    And i have the same problem and im not sure if it starts
    When i changed My pinion gear from 31t to 34t or when i did the app upgrade
    And now The rpm shows very far over 267.000 rpm at 1/4 throttle and drops more as faster It goes
    And i also tested with the included nimh pack and the gps shows 109kmh =67mph with 1/4 throttle. And My upgrades is not Done yet because of this issues

    RPM is a problem with the recent app update. Do you have the Telemetry Expander?

    Yes, I do. Actually I should try removing it, because it didn't do it with the expander in although the speed of course was off then. But I hadn't updated the firmware at the time either. So not sure if it's due to the expander being in or the new update or what. But the tech did say it wasn't an issue with the car but the app itself.

    The first thing the rep asked was "Do you have the Telemetry Expander", yes I do.
    I have a second Slash 4x4 TSM VXL that over the weekend, I added Telemetry with RPM, no expander, and it works correctly with the same phone and App. Sure looks like the Expander is causing this but I don't know.

    I disconnected the Expander and the RPM reading was normal.
