ESC2 vs Powerband Precision

ESC2 establishes a connection through the Bluetooth of the mobile phone and the Bluetooth of the ESC, so as to realize the functions of adjusting the parameters of the ESC, viewing the data, and upgrading the firmware.

Hear your engine. Understand your tune. Race with confidence. From the developer: I'm Lucas, the developer behind Powerband Precision. I got my first 1/8 scale GP car at 13 years old- the excitement had me partying like it was 1999 (but this actually WAS year 1999). From there it took me years and years of trial and error to finally feel I could tune my engine-no internet or RC forums to ask questions, no YouTube to watch for tips and pointers. I built this app because I know what a pain tuning can be and how it could push someone to feel like they want to quit the hobby. Knowing why an engine is making the sound that it's making can make tuning a walk in the park. Through my website, I receive engines from around the U.S. for break-in, rebuild, troubleshooting, etc. Any engine that receives a tune, I log it into the app which anyone can see that has the app installed on their device. Although a tune is more so engine/local conditions specific, the final outcome is always relatively close, making logs a great reference tool. Every engine baseline comes from the manufacturer's instruction manual or deep research and matching to other engines. Sounds have been recorded from my personal vehicles/engines while on a dyno , and all the diagnostic/troubleshooting issues I have experienced myself or have watched them happen. Thank you!
