M1 Development License v1.4 to 1.4.1 Upgrade

If you already have a 1.4 M1 build development license, and you'd like to have the ability to compile 1.4.1 build files, then this is what you'll need. This is required for your ECU to move from 1.4 to 1.4.1.

This works for all plastic connector M1 ECU's both port injection and direct injection.

Please include your ECU serial in your address or email us at info@trialengineering.com after placing your order.

_ Ensure your serial number is accurate. This code is not refundable and cannot be moved to a different serial number after ordering.
