Connections are fun sometimes -- there used to be a program on PBS called
Connections, where the writer/host would take some invention a thousand years ago and trace it to some technology used to go to the moon, or similar.
Some time ago there was a thread (one of many) about upgrading the front suspension on the Rocket, and
@barbagris pointed out
emulators available for the Touring out of California.
Looking at that, turns out there is a dealer for them (they call them "RT Centers") in Pasadena, MD, and turns out that dealer,
MRP Motorsports, also offers tuning.
So I got to talking to the tuner, Kenny, and he said it's easier with Power Commander installed, but they know how to do it with Tune ECU. He said ballpark figures are $250 with PC, because they do it on the fly, and closer to $400 with TuneECU because they take readings, have to turn off the bike, make adjustments, reload the adjustments, rerun the bike, and so on.
I think I'm going with the non-piggyback version, just as soon as I receive the full exhaust from
@Paul Bryant .
I'm tentatively a happy camper.
