-Description-
We are proud to have truly mastered the MS45 ECU. We know some of you just want to keep it simple, so offer you the ability to simple bypass JUST the rear o2 sensors and secondary air pump (SAP) for your catless headers.

Chaos Calibrations offers some of the most in-depth calibrations for the MS45 ECU platform in the world with the most extensive feature list till this date. With access to thousands of parameters and proper documentation, we can unlock almost anything your heart desires. We have spent countless hours dialing in calibrations for both Naturally aspirated and forced induction applications. You can be rest assured when you purchase your MS45 ECU tune for your ZHP, facelift E46, E60, etc.; you will be receiving the best tunes and support bar none.

-What's the process?-
You are purchasing our remote tuning service. After purchasing your tune, you will receive an email with our software download and instructions to begin the tuning process. It is a very straight forward process. You will need a Windows laptop or Android Device and K+DCAN OBD2 Cable.
You'll essentially check for any codes the car may have and save them. Then pull a backup of the ECU as it currently sits and send it in to us. We'll then build your tune, and send it over to you for uploading. It's easy as that!
Go to our FAQ for more details on the tuning process.
Remote Tuning Software Support:
• Windows Laptop/PC Software
• Android Mobile App (CCFlash Mobile on Google Play Store)

For MS45 ECU Tuning, it is HIGHLY RECOMMENDED to use quality cables with updated firmware. Generic cables from ebay and amazon (and similar) with outdated firmware can cause issues when uploading tunes to your ECU. If you are unsure about the cable you might already have, feel free to ask us and we can let you know.
