Most Packard tunes are a mail-in flash: you pull the ECU, ship it to Clearfield, we flash it on the bench for your build, your fuel and your elevation, and ship it back. Here’s the whole trip, the Preload-or-Flash-now choice on supercharger kits, and where the ECU is on your machine.
There and back
Check each one off as you go; this page remembers where you are on this device.
The tune you order is the flash we build: the stage, the fuel and the options. Order it (or the kit that includes it) before you ship anything.
Supercharger kits with the tune ask one more question at checkout, Preload or Flash now. That’s explained below.
The send-in form takes about two minutes, and you get a printable form with your answers already on it. Have these ready:
Print the send-in form. It goes in the box with the ECU, so we know whose it is the second it’s opened.
Key off first. Where it is and how it comes out depends on the machine; pick yours below.
Send only the ECU module, never the harness. Pad it so it can’t move, and put the printed form in the box.
Use any carrier with tracking. Shipping to us is on you; we ship it back with tracking.

Reverse whatever you did to pull it: connectors seated and locked, hardware back in, covers and seats on.
If you picked Preload, your machine is still on the stock tune. Install the kit, then write the supercharger tune with your HP Tuners device. Step-by-step →
If you picked Flash now, the supercharger tune is already active. Leave it parked until the kit is on.
Some tunes have settings you select on the machine. On the Z10, launch rpm and fuel are set key on, engine off, and the gauge confirms for 15 seconds. The steps for your options come with your order.
Supercharger kits
Plenums take 7–10 days to build and supercharger kits two weeks to a month, so your flashed ECU usually beats the kit home. You pick how it comes back.
Either way, the supercharger tune won’t run right without the supercharger. Applies to Polaris kits that include the tune: Pro R and Xpedition.
Where’s my ECU?
From Packard’s own install videos and instructions.
Your machine’s service manual shows where the ECU is and how it comes out. Not sure? Ask the shop; tell us the year and model and we’ll walk you to it.
Whatever the machine: key off before you unplug anything, pull on the connector body and never the wires, and send only the module.
Already tuned?
Already running a Packard tune? Ask whether a newer calibration exists for your machine. We answer when you ask; we don’t send update emails you didn’t request.
Questions
No. Only the ECU module.

Elevation changes how your tune fuels. We map it to where you actually ride.
Plenums take 7–10 days and supercharger kits two weeks to a month, so the flash is usually done first. That’s why supercharger kits ask Preload or Flash now.
No. It won’t run right without the supercharger.
Say so on the form, with who did it and what was done. It changes how we handle the flash.
