neoECU 20: IO Map

neoECU 20 does not have a pin map. neoECU 20 is configured using neoVI 3G Explorer, in the same way as a neoVI FIRE or neoVI Red would be used. Scripts are loaded into the device over USB just like a neoVI device. Table 1 lists the Pin connections for the device. You should also find this on the back of the neoECU20. The networks setup and functions of the neoECU 20 match a neoVI FIRE and standalone scripts are compatible between the two devices.
