Z10 ECU.
Pull it. Ship it.

The Packard Z10 tune is a mail-in flash: you pull the ECU, ship it to Clearfield, we flash it on the bench and send it back. Getting to it is the easy part. Here’s every step, from the seats to the box, and what to do when it comes home.

Before you start

What you’ll need.

Tools

  • Phillips screwdriver
  • Small cutters for the zip tie
  • A fresh zip tie for the reinstall
  • A cup or magnetic tray for four screws

To ship it

Know this first

  • Order the tune before you ship: the stage and options you pick are the flash we build.
  • Send the ECU only, never the harness.
  • The car doesn’t run while the ECU is out.

Out, shipped, back in

01

Before you pull it

Step 01· Done

Order the tune and fill in the send-in form

Order the Z10 tune first: the stage, launch control and fueling you pick are the flash we build. Then start your send-in. It takes a couple of minutes: the VIN, your order number, the stage you ordered and where you ride most, because elevation changes how the tune fuels.

Print the send-in form it gives you. It goes in the box with the ECU.

Have readyVIN · order number

The ECU part number on the module label is optional on the form. You’ll be looking right at it in step 05.

02

Get to the ECU

It lives under the middle compartment, between the seats.

Step 02· Done

Slide the driver’s seat forward

Just far enough to give yourself room to work in the middle of the car.

Step 03· Done

Take the passenger seat out

Grab the latch, lift the seat and slide it out of the car.

Step 04· Done

Open the middle compartment

Unlock the cover, then slide it forward and up to lift it off.

Step 05· Done

Find the ECU

It’s right there under the cover. Before you start, count what holds it in: four screws, one at each corner, two electrical connectors and one zip tie.

03

Pull it

Step 06 · General practice· Done

Key off

Turn the key off before you unplug anything. Disconnecting the battery’s negative terminal is extra insurance, not a requirement.

Step 07· Done

Cut the zip tie

Small cutters, side cutters, whatever you have handy. Snip the zip tie and get it out of the way.

Put a fresh zip tie in your pocket for the reinstall.

Step 08· Done

Take out the four corner screws

A Phillips screwdriver, one screw at each corner.

Drop the screws in a cup or a magnetic tray. They’re the only hardware you need to put it back.

Step 09· Done

Unlatch and lift both connectors

Each connector has a plastic locking tab. Slide the tab forward, and the connector comes straight up off the ECU. Do the second one the same way.

Pull on the connector body, never the wires. If it doesn’t lift, the tab isn’t all the way forward.

Step 10· Done

Lift the ECU out

With the screws out and both connectors off, the ECU lifts out of its tray. That’s the whole job.

04

Ship it

Step 11· Done

Box it with the send-in form

Send only the ECU module, not the harness. Pad it so it can’t move in the box, and put the printed send-in form in with it. No form handy? Your name and order number on a sheet of paper in the box.

Step 12· Done

Ship it to Clearfield

Any carrier with tracking. Shipping to us is on you; we ship it back with tracking.

The car doesn’t run while the ECU is gone. Drop the compartment cover back on to keep dust off the open connectors.

When it comes back

Step 13· Done

Stage 2 or 3: the injectors are in the box

Stage 2 and Stage 3 come back with the Bosch 1000cc injectors in the same box as your ECU. They have to be in the car before you ride on that map. Questions about the injector swap? Ask the shop.

Step 14· Done

Put it back in, in reverse

  1. Set the ECU in its tray.
  2. Press each connector straight down and slide its tab back to lock it.
  3. Four corner screws, snug.
  4. A fresh zip tie where the old one was.
  5. Compartment cover on, passenger seat in, driver’s seat back.
Step 15· Done

Set launch rpm and fuel, key on, engine off

Launch rpm and fuel settings select with the key on and the engine off, and the gauge confirms the setting for 15 seconds. The steps for the options you ordered come with your order. Then go find some sand.

Which stage do I order?
