You pull the ECU and send it in. We write the calibration on our bench in Clearfield and ship it back.

Your phone writes it
An HP Tuners RTD plugs into the car. The HP Tuners TDN app on your phone writes the tune we send.
Pulling a Z10 ECU for the mail-in
- Key off and disconnect the battery.
- Take a photo of the plugs before you pull them.
- Unplug the connectors and unbolt the module.
- Send the module only, not the harness.
- Wrap it so it can’t rattle and ship it with tracking.
