Does PCFC for SR400 work in both open/closed-loop mode and in all RPM & TPS range? Power Commander Fuel Controller for 2015-2018 Yamaha SR400
Hi~ It looks like the PCFC connects to the injector and TPS sensor.
But in closed-loop wouldn't the O2 sensor detects a rich mixture from added fuel and try to correct it back?
Thanks for the help!!
