Title: Dual tune ECU ME7.5 Post by: Lkz666 on June 18, 2024, 05:10:37 PM Noob question... I have an ME7.5 ECU with 1MB flash file size. I would like to be able to switch between E85 fuel and USA 91 octane. Is it possible to switch tunes without connecting a computer to the ECU?
For example I'm on E85 fuel and I run out of gas and the only thing available is 91 octane and I don't have my laptop with me. I previously had a dual tune E85/91 octane from Motoza but I had to use my laptop to make the change. What are the options for changing tunes without a laptop? Thank you.

Find a tuner who offers this, since based on what you are writing here you're not DIY anything. |
