Project

Graph-Tune 1.0 - electric turbo / supercharger dot they really work ? Stay tuned and find out!

Graph-Tune 1.0 is a private project & experiment, started year 2021 and is ongoing as you read this..

In this project a 100%  electric driven “Turbo” / compressor will be installed on a old veteran motorcycle. The motorcycle will be dyno-tested and the results will be shared regardless outcome.

The project will also contain a AFR (Air Fuel Ratio)-data logging solution  to make it possible to connect the computer to the vehicle and log the exhaust values. Values will be visualized in a graph for further analysis, a perfect instrument for further optimization and make it possible to not guess whats the best settings is for the vehicle.

 

The motorcycle will also be rebuild in CaféRacer style.

 

This website is also one of the tasks in this project and the idea is to make a community with help of the FORUM and the BLOG, make us poeple share knowledge about all kinds of "e-boosters" and AFR-data logging solutions​.

Let´s share knowledge and build together.. join our FORUM 

 

Follow the BLOG!

 

What will the results be.. stay tuned and find out!
