Hey Stu, how about enlightening the OP and me. Searching through the information available online at V&H I don't see any detailed instructions showing all those options and settings. What exactly do you see that can be modified?

The best way to get an idea of the settings you can change with the Fuelpak FP3 is to download the App and run it in demo mode.
You can change things like: Throttle Progressivity, Frt and Rear Cyl VE, Frt and Rear Charge Dilution effect, Decel Pop, AFR, Accel Enrichment, Decel Enleanment, Closed Loop Activation Points, Spark Advance, Knock retard, Performance enrichment tables, Idle speeds, Speedo Calibrations & MUCH MORE.
Don't ask me what all that stuff is because - I Don't know!
It sounds like the TTS is great and has more functions if you are a computer savvy tuner and want to be able to tweak whatever you might want, but the FP3 seems to have all the stuff that 'most folks' would need to mess with? With a little shopping around I found it for $309.00 which is < a TTS?

I know the FP3 worked great for my friends 2014 CVO Road King that lean popped, ran hot and backfired all the time to the point it was yellowing his pipes!
