PPMPR: The MyChron3 Plus Installed
Posted: Tue Jun 13, 2017 9:39 pm
Here are some shots of the MyChron3 Plus installed. The dash unit connects to an accessories box. The sensors plug into the box. There are five possible sensors. In the photo on the bottom is a wire loop—this is the sensor for the tachometer. Above that are the two temp sensors, speed sensor, and beacon sensor connectors. I've currently only got the speed sensor, and temp two connected. The temp one sensor connection will show up when I get the EGT sensor, and I may switch the CHT sensor for an H2O sensor. The beacon I wont be using.
The wires at the top are the power mod wires. These connect to a small 12 to 7.5volt convertor that is directly connected to the battery. I need to change this to feed off the key switched power. The MyChron will kill the poor Shirai lithium battery. The lid I had to use was one of the crashed up ones. I have a nicer lid for the unit, but I have to mod it to work with the external power mod.
To attach the box we used two self tapping screws set in a pair of pilot hole drilled into the dash mount. The bottom was secured with a zip tie. The dash is secured with one nylock nut.
