IAT sensor mod

[Hooli]

Not really knowing but just a thought. Im sure youll set me right. We add Power Commander, take it to dyno. Everything set at perfect A/F. This was done at a certain ambient temperature. Lets say 15 degrees C.  Here we go down to 5 but up to 45. My thinking is IAT will change A/F ratio. Should IAT be dis abled to keep perfect A/F. Old days with carbs they basically stayed same with air temp. Not so with altitude.

No as Andre said, air density varies with temp.

Also carbs did stay roughly the same for altitude, but the thinner air, being less dense, makes the mixture richer. On our bikes the pressure sensor on the RH side of the airbox allows for that & the ECU leans the mixture off as altitude increases to keep it running right.
