I was having misfiring issues and loss of power at low RPM with my bike for years. I took it to Harley and they said it was fine, then I took it to another shop who knew it wasn't right but couldn't find the problem. I read that there are issues with some stock ECM's. The ThunderMax was the best investment to replace my stock ECM and customize my tune. It runs like a new bike!
easy to install and load base map haven’t got bike in a day I yet but tuning software is easy to use but could be set up a little better
Easy to install and easy to get started with
The hardest part is finding the right tune. After that you HAVE TO CONNECT to the computer after riding it a few hundred miles and set the learned as the base. After you shut off the bike it goes back to the base tune and relearns the fuel air ratio. I’m getting great mileage with this new computer and have good power.
It fit like OEM on my bike. I have yet to use the tuning feature. A little pricey but worth it. Program was easy to download and use.
Spend the money. Nothing else compares.
So far so good?? More money than I wanted to spend but I really like the auto tune. Installed and tuned it all myself.... can't say that it didn't make me nervous, but it runs great!
Great purchase and straight forward hookup. TMax tech was great to work with and helped find the perfect map.
Installation and set up was very easy. So far it is working great. I look forward to learning and using the system to improve performance in the future.
