Frequently asked questions

Does SDT include an ALDL cable?

No. This listing is the software only. SDT is designed for use with our ALDL Cable v2, sold separately. Already have an Envyous ALDL cable? You can use it with SDT.

Does SDT work on my LS1 V8 or VZ?

Yes. SDT works over ALDL on all VT, VU, VX, VY and VZ Commodores, LS1 V8s included, and on WK and WL Statesman and Caprice.

Will clearing the code fix my airbag light?

Clearing removes the stored fault codes. If the fault is still present, the module logs it again, so use the detailed system data to track down the cause first.

Can I install it on more than one computer?

Each licence registers the software to one computer. A licence serial can only be used once and can't be transferred to another computer later. See Software Licensing for the details.

Do I need internet access?

Yes. Registration needs an internet connection, and offline activation isn't available.

Which version of Windows do I need?

A genuine, activated copy of Windows 10 or 11. Virtual machines and emulators aren't supported. See Computer Requirements.

How do I get the software after I buy it?

Your licence serial is emailed to you after purchase and is also available in your account. Download the software installer from our Downloads page.

What if my computer crashes or gets wiped?

Make a full image backup of your computer after you register the software. Licences can't be reissued, so the backup is how you get your licence back after a crash or wipe.

Do I get updates?

Yes. All of our software includes lifetime updates.
