Unlock My ECU!
Unlock My ECU (UME) is the worlds first Holden dedicated ECU key finding software…
Unlock My ECU’s whole purpose is to find the “password” or “Key” that is required to be entered into tuning software to unlock and get into ECU’s and TCM’s allowing dedicated Tuning shops or even the DIY’ers to retune their vehicles!. Unlock My ECU’s features include:
- Read out calibration Part Numbers, Vehicle Identification number and Serial numbers
- Change and write a new vin on supported ECU’s!
- Quickly Check Seed/Key combinations
- Bruteforce and find any Key for Locked ECUs and TCMs
- Fail Safe system that logs progress incase of disconnect during unlock search!
- The worlds only dedicated Holden ECU/TCM key finding software!

How Does it Work?
Think of the ECU key (Password) like the 4 digit passcode on your iphone or android. Without the correct password, you cannot access anything on the phone such as images or messages. You can only access this content AFTER the correct password is entered, which unlocks the phone allowing access!
ECU’s work the same way, they need the correct key entered everytime you want to read or write a tune. This process of entering the key each time is called “unlocking”. Without this key, noone can retune the vehicle, this includes all commercial tuning software and also Holden factory scantools.
UME’s sole purpose is to find this key. It does not edit or remove the “lock”, it exclusively searches out for the correct key that allows access into the ECU. The key is found by bruteforce (No, not with a hammer!), which means it tries every single possible combination until it finds the correct key!
What do I do with the found Key?
The key needs to be entered into suitable software so that the ECU can be read and written to.
The BEST option available is to use TunerCats to write a fresh file into the ECU so it is back to stock standard. This is a three step process as seen below:
1. Flashing the ECU back to a standard operating system (OS) will prevent any issues with incompatible operating systems with EFILive or HPTuners.
2. The ECU can then be set back to the default key using EFILive’s lock/unlocking feature.
3. Finally, the ECU is fully accessible through EFILive for tuning as the ECU has been returned back to Factory conditions. Please note that HPTuners may still not be be happy due to the way HPTuners reads tunes from the ECU thus is not recommended to use.
Many tuning shops have different methods to wipe an ECU back to factory after obtaining the key, but the above is the most popular, kindly donated/shared by a bunch of great tuners!
Other tuners have mentioned that once they have the key, they can load up a stock calibration and simply flash that straight into the ECU to overwrite any custom OS. So its a matter of trial and error to see what works for you!

How do I get Unlock My ECU?
UME will be available again shortly.
We have completely redesigned the software and now use a an industrial tool (VX Diag Nano) for performing the key finding procedure.

Common Questions and Answers
Q: I only have HPTuners, can I just use that with the key?
A: Yes you can, but there are a couple catches..
First off, Unlock My ECU!(UME) finds the custom unlock key to allow reading and writing to the ECU. This key is a password, without the password you cannot access the ECU in anyway.
HPTuners does not allow you to view or edit ECU tunes that have been locked by other tuners, the warning you will receive is “Locked by another tuner”. You will be able to read the locked ECU tune using the found key, but will not be able to view and edit that tune after getting the key. This is HPTuners way of protecting other tuners intellectual property, whereas other companies (Such as EFILive or our own tuning software) do not prevent tuners from viewing a locked tune, it is a hptuners thing only.
To get around this issue in HP, you must either:
1) Perform a full OS+Write using the found key and a stock unlocked tune compatible for vehicle (Start fresh, which should be the go to always!)
2) Use a different tuning software to remove the custom lock and then re-read with hp tuners.
Secondly, if the ECU is running a custom operating system (OS) which is not supported by HPTuners (Such as an EFILive custom OS), then you will HAVE to write over the ecu (Full OS+Cal) with a stock tune and edit from there.
Q: Can I use HPTuners/EFILive to flash in a stock tune or OS?
A: Absolutely, this is the recommended method
Starting from fresh ensures the commercial tuning package being used is able to happily access and modify ecu.
Q: I have my own cable, can I use that?
A: At this time we only accept cables provided by us to ensure reliability and longevity. Also, our licensing relies on using unique information from the scantool which is preloaded onto our website that is used for licensing.
The scantool we are using is called a VX Diag Nano for GM, all initial purchases must select to have a cable included, all first time orders without a cable will be cancelled.
Q: When does my Subscription start and finish?
A: Your subscription will start from the moment you register UME using your subscription license serial. Our licenses are a 1 year (365days) license, this will end in 365 days from the exact time you enter it into the software.
Q: I have multiple computers, Can I run it on all of them?
A: Yes you can!
Our new application links the licensing to the scantool. This means you can install onto every computer, so long as you use that scantool.
If you want to be unlocking 2+ ECUs at one time, you must purchase TWO scantool+software kits.
Q: I need to retune/wipe locked ECU’s, but do not want others to be able to see my hard tuning work?
A: Yes I completely agree, and this is where the moral dilemma kicks in!
No-one wants their hard work to be copied, but then still need to be able to access locked ECU’s to perform a full retune, unfortunately you cannot have one without the other. Most of the people reading this already use an unlocking service.
Unlocking services have been around for as long as the ability to lock an ECU has, the only difference now with UME is the unlocking can be completed in house rather then shipped interstate or overseas, drastically reducing lose of shipment and also minimizing costs.
The “cowboys” that just copy a tune, have been doing so for many years. They will never understand the tune, and will solely be to blame when (not if) they attempt to flash a vehicle which is not suitable causing massive engine damage, or brick an incompatible ECU!
A real tuner (As many can agree!), just need an ECU set back to factory so they can perform their own work.
