Anyone ever thought about putting the Power Commander (or for that matter an ECU editor) program onto phones? Yeah, I know...I never thought I would have needed it either until:
We did some tuning on the bike and opened up the auto tune % to a wider range to see how it would tune out using different race fuels, etc.
After the event I had the top end redone and forgot to narrow down the % range of the auto tune. Went on a ride the other day (about 100 miles or so) and ran good until the last 20 miles homeward and I notice the AFR guage shooting pretty high on acceleration but read fine at cruise.
Anyway, I got home and hooked up the laptop and sure enough something had made the trim tabs go to my max settings on the lean side so I adjusted the trim out. Went for a test ride and ran fine.
I know everyone does not run into a situation such as this and many do not run an autotune program, but my thoughts are if something went wacky 200 miles away from home...what are you going to do with no laptop.
It defeats the purpose of the autotune to turn it off.
One question is, what made it tune to the lean side. I have a couple theories on that.
One is I still had some old 112 octane race fuel in the tank that maybe had gone bad.
Second is we had added some extra fuel through the ECU (because my A/F sensor had gone bad and was not reading) but this extra fuel should be only on a toggle switched map, not all the time.
Anyway, I can see a need for a phone app to be able to plug into a Power Commander unit or ECU editor in an emergency.
