Add to cart

One editor, two environments

Built for the bench.
Ready for the vehicle.

Choose direct bench communication or the recovered in-vehicle BCM/INS handover. Use a selectable COM port with a USB ALDL cable, or choose a compatible installed 32-bit J2534 interface.

Bench cluster

Direct, controlled testing

Ideal for spare-cluster validation, backups, display tests and bench-only Mode, Set, Up and Down overrides.

DIRECT

In vehicle

BCM/INS bus handover

Uses the recovered bus-control sequence before IPC requests and reopens the session when verification requires it.

IN CAR

What it handles

Complex protocol.
Plain-language controls.

Customer activity shows clear success, warning and failure results. Protocol frames, security values and write sequences stay out of the subscriber interface.

Identify & preserve

Know the cluster before you touch it

Read the detected profile, GM part number, fuel calibration, manufacture data and hardware level, then save a mapped 512-byte EEPROM backup.

Cluster IDProfile reportEEPROM backup

Configure

Guided VY and VZ configuration

Work with vehicle configuration, fuel sender calibration and dependent SRS selections without needing to remember raw ALDL frames.

Fuel & ohmsSRS dependenciesRead-back

Personalise

Displays that suit the vehicle

Read and write supported Holden, HSV, Chevrolet, Omega and CSV boot screens, plus HSV vehicle type, build number and ten-character custom text.

Diagnose & test

Useful checks without the clutter

Read the confirmed IPC fault table, issue the explicit clear command, run gauge tests and use bench-only trip-switch overrides.

Connection & identification

Start with the cluster in front of you

Choose bench or in-vehicle mode, select USB ALDL or an installed J2534 interface, then identify the cluster before changing it.

Fuel & backup

Mapped backups and sender calibration

Create and compare backups, inspect sender ohm points and select a vehicle-labelled fuel calibration.

Configuration

Vehicle and fitted SRS hardware

Read the fitted configuration, then work through guided vehicle and dependent airbag selections.

Displays & tests

Boot screens, HSV text and bench controls

Personalise supported displays, run cluster checks and operate the trip switches during bench testing.

Live data

Read-only IPC table monitor

Inspect confirmed table data while unknown bytes remain clearly marked instead of being guessed.

Programming safeguards

A write should prove what happened.

V13.7 creates one immutable baseline before the first supported write, then reuses it until disconnect or a different cluster is detected.

Detects the native VY/VZ profile before guarded writes
Creates one mapped baseline before the first supported write per connection
Performs a fresh security unlock immediately before programming
Reads the same record or table back after the write
Keeps Pontiac and unconfirmed VZ operations behind explicit boundaries

Programming still requires a stable 12–14 V supply and controlled testing. Newly recovered write paths are offline-tested and should be validated one change at a time on spare hardware.

For experienced users

Recovered tools, without exposing protocol internals.

V13.7 includes guided legacy writes and guarded record/table editors for confirmed storage layouts. Unknown values stay labelled unknown, while owner-only diagnostics remain separate from customer activity.

Good to know

Before connecting.

How much does access cost?

The VY/VZ IPC Editor is $80 AUD per month. Choose 1, 3, 6 or 12 months before checkout. Creating an account does not charge you.

Can I sign in before paying?

Yes. A new account can sign in and continue browsing the website, catalogue and cart. Downloads and application login remain locked until payment is confirmed.

Which clusters are supported?

Native Holden VY and VZ IPC profiles are the primary target. Pontiac/native-VZ compatibility is kept separate where it has not been proven.

Does it work through the normal OBD-II protocols?

No. These clusters use GM ALDL at 8192 baud on J1962 pin 9. J1850 VPW/PWM and generic OBD-II protocol numbers are not substitutes.

Are all raw values decoded?

No. Data Tables 0–9 can be viewed read-only, but unproven byte meanings and scaling remain visibly unknown instead of being guessed.

Does access automatically renew?

No. The current product uses a fixed prepaid 1, 3, 6 or 12-month term. A future recurring offer would need to be clearly identified and separately authorised at checkout.
