Step‑by‑Step Altis Sigma Battery Firmware Update Instructions

1. Inspect the Greenway Module

1. Locate the tiny DIP switches on the front.
2. Ensure both switches are flipped down (OFF position). This places the tool in standard update mode.
3. Check the rear connectors: one is labeled 4 H (High CAN), the other 3 L (Low CAN). They’re pre‑glued, but confirm nothing came loose in shipping.

✅ Pro Tip: If a plug is dislodged, match 4 H → H pin and 3 L → L pin per the printed lettering on the module.

2. Connect the Module to the Battery

1. Lift your Sigma’s seat to reveal the BMS port block.
2. Plug the 4 H connector into the left‑most port (see diagram below)
3. Plug the 3 L connector into the right‑most port.
4. Rest the module on the sub‑frame so it can’t fall or tug the wires.
   
    
   
   

3. Power the Module via USB

1. Plug the USB‑A cable into your laptop.
2. Connect the USB‑B end to the Greenway module.
3. You’ll hear a Windows chime and see LEDs on the module start flashing.

4. Download & Extract the Firmware Package

1. Altis support will email you a .zip file named Sigma_Battery_Update.zip.
2. Save it to your Downloads folder.
3. Right‑click → “Extract All…”.
4. After extraction, verify the folder icon shows no zipper—a zipped file will NOT flash successfully.

5. Install the CAN‑USB Driver (First Time Only)

1. Open the extracted folder and double‑click Driver/net‑framework.exe.
2. Windows may prompt for permission—click Yes.
3. If you already have Microsoft .NET 4.0 or higher, you’ll see “The same or newer version is already installed.” Click Close and move on.

6. Launch the Greenway Flasher Tool

1. Back in the main update folder, open G001/PressureDownload.exe.
2. Choose English at the language prompt.
   
   

On the main screen:

* Double‑check that the Greenway LEDs are blinking rhythmically—this indicates CAN communication.

7. Flash the Battery Firmware

1. Click Download.
2. A progress bar will appear; the entire write process takes 30–60 seconds.
3. Do not unplug the USB or battery cables during flashing. You’ll see the module’s LEDs accelerate as data transfers.
4. When you see “Download Successful”, click Close.

8. Disconnect & Reassemble

1. Safely eject the Greenway module in Windows (optional but recommended).
2. Unplug the USB cable.
3. Remove the 3 L and 4 H plugs from the BMS block.
4. Re‑install your seat. You’re done!
   
   

Post‑Update Checklist

If you encounter any fault codes after flashing, contact REV Rides support with:

• Your bike’s serial number
• A screenshot or photo of the error
• The firmware file version you used
  
  

Frequently Asked Questions

Q: Is this firmware official?
A: Yes. The .bin file is distributed directly by Altis Powersports and “signed” for Greenway BMS hardware.

Q: Will this hurt battery longevity?
A: No. Lowering the unlock temp from 25 °C to 10 °C stays within cell spec. You still get full cold‑charge protection under 0 °C.

Q: Can I use the same tool on multiple batteries?
A: Absolutely. Just repeat the steps for each pack. Make sure the DIP switches remain down.

Q: Does the update increase top speed or power?
A: Power maps stay the same. You simply reach full amps sooner on cold mornings, so the bike feels stronger from the first throttle roll‑on.
