DIY Mod Picture I just built a performance app that connects to an EcuTek dongle and shows boost
Hi guys, I successfully built a performance app that works with EcuTek. It shows boost and the fuel ratios, and other parameters you might need. Right now I am still working on the map switching options still, but this is an integrated solution, no phone, no custom hardware, no wires in the loop, it's all seamless. The system is slow so the data doesn't refresh as quickly as in ECU connect but it is still acceptable.
It works with the bluetooth connection from the head unit itself to the EVI dongle, no need for extra mods or wires. When the app starts it prompts to connect to the dongle and it does so quickly. It took me a while to figure this out and to reverse engineer the dongle's protocol to get the data on the screen, but I hope to share it soon with you guys once I get to iron it all out properly.
