I've read a couple of threads where they had to re-dyno their bike cause of change in weather (hot to cold), change in altitude. Is this really necessary? or did I just waste $300. and should've gotten one of those tuners that continuously adjusts themselves.

Why is it that when you change the exhaust in your truck or car there is no need to remap?
EFI is supposed to do these things automatically :hmm: :hmm:

Oxygen Sensors!!!!
Ours don't have them, so there is no automatic adjustments from the ECM!!

oxygen sensors doesn't seem too hard to install

If anyone is tuning their bike constantly with temperature changes they are obviously racing the bike, normal street bikes should only have to dyno once and be done, unless you go from the eastern coast to say denver then you would have to retune. I have a PC3 and it was dynoe'd just once and done. I have no temperature issues with my tune.

Does the efi not automaticaly adjust based on sensor input for air temp and barometric pressure?, you should not have to retune for weather or altitude!

The only thing I know of that adjusts your tune is the IAT sensor...
How that has an effect on the pcIII, i dont know yet. I havent ordered mine as of now.

Some people just like to fiddle with their toys all the time.

Tune it once and forget it.

The EFI system adjusts for temperature, not pressure, as there is no Mass Airflow Sensor. The 2008 system should allow for changes in pressure and density altitude with the addition of O2 sensors.

I sold my PCIII and got a RT. Prior to the RT, I was running RJ's map with my v-modded stockers, which is universally known as one of the best PCIII maps available for that combo. While it was a very good map, my overall perfomance was much smoother with the RT. Overall power is the same, but everything is noticablly smoother.

How did you go about building your map for the SERT?
