5. Nano PRO Electrical Installation
The Nano PRO has a 12-way connector with 3 wire groups. One of them has the connector for the O2 sensor, the
second makes the CAN communication with Power FT ECU’s and the third is responsible for power and analog output.
By default, the analog output is set to values of 8.7AFR to 16.2AFR Gas, but can be congured to 5.1AFR to 17.6AFR
Gas or 9.6AFR to 19.1AFR or 9.6AFR to 58.8AFR or yet 9.6AFR to 146AFR (Gas), if necessary.
See the following wiring diagram for details about connections.
