I agree with the Carpenter racing mods.. I so want to do that with my Rocket.. I have teenagers slowing me down though.. lol
If you're just wanting to get your ECM to match your Jardines..
DynoJet PC-III and now PC-V are the most reconized and easy to adjust by most any Dyno shop anywhere. They don't change your ECM per say, they modifiy the fuel map AFTER your ECM.. adding or subtracting fuel as directed by the fuel map stored in the PC-III or V. DynoJet does have a "canned" Jardine tune on their site as well.
TuneBoy is a rather expensive program that you load custom fuel maps, modify ignition timing, read error codes, adjust speed limiter, adjust RPM limiter, anything and more that the dealer can do. However, most dyno shops are not familiar with TuneBoy. There is alot of support on either forum though.
TuneECU is a freeware version of TuneECU. Same options.. same problem with not alot of dyno shops familiar.. but good support on both forums, and the TuneECU people post frequently on both forums.
