Wireless MegaSquirt via Bluetooth

 Out of stock!

Class 1 RS232 Bluetooth

Proven, tested and pre-configured to work for your Android phone and MegaSquirt. When working with RS232 over bluetooth you quickly find that RS232 Bluetooth Adpaters vary greatly. With Bluetooth you will always see slower read rates than with a cabled connection, but with a good bluetooth adapter, bluetooth is plenty fast at 20+ reads persecond with some firmwares. However we have seen significantly lower data rates when using some devices, as much as 45% few reads each second.  More commonly a newly purchased Bluetooth Adapter will not work at all until you figure out the configuration settings that are needed.

This is why we tested many to find one that out performed all others tested, then preconfigure them so it will work for you out of the box.

- Class 1 range (100 meters), so even with all the obstacles of a car, you can still tune outside the car and from a distance.
- Preconfigured for your MS1, MS2 or MS3
- No Need for Modification to your MegaSquirt or MicroSquirt!
- Highest read rate of any Bluetooth Adapter we've tested.
- Powered by Pin 9 on
v3.0 or v3.57 board or use an included power adapter.
- Certified for use with Shadow Dash MS and Shadow Logger MS on Android
