Just your thoughts. Anyone used one? I know it just tricks computer, tells it air is colder. We all know our bike goes better in cold conditions. Just adds more fuel, pretty much what Power Commander  does. Splices into IAT, wouldnt a resistor do same, if you knew which one. Thoughts gentlemen. https://www.magnumtuning.com/en/detail/dyno-boost-motorcycle-performance-chip/suzuki/gsx1400-efi

Yup a resistor would do the same.

The manual gives rough values for the sensors resistance so you could work out the one you want...

BUT

The reason it adds more fuel in cold is, is that cold air is denser so you need more fuel to get the correct air/fuel ratio. All tricking the bike into thinking it's colder will do is make it run richer than it should. It'd be exactly the same as just fitting bigger jets in a carbed bike.

My 14 has an Akra system & the fuel map on the PC3 is equally split between less & more fuel than standard. So what you're thinking of would improve it in some places & worse in others. From memory mine is a lot leaner on mid-range, so it'd be worse at the revs most of us normally ride at.

Hooli, just put it out there. Im not doing at all. A resistor for $1 would trick it. Around 2k ohm would make it think around 8 to 10 degrees C. Just hope no one paid $249. Also thinking a variable resistor on bars would be fun. Seat of pants adjust.

Aye I can see your logic, I'm just saying from the tunes I've seen it'd cause as much reduction in performance as increase.
