Goodfellow, I applied the vaseline jelly to those 6 connectors on the coils. I pushed them on and off several times to clean up the contacts. The beast had been suffering from a faint feeling of lost power (a faint missing hit, in the same RPM range) for awhile. The definite cutting out at cruise came on suddenly and clearly preceded by the previous faint losses. Since performing this maintenance function the ailment is totally gone. And MPG is up a tad. This may be a result of the above action or the retuning with the 20220; I'll never know.
Pig9r, the TuneBoy diagnostics gave me values of 484 485 and 463. I assume that to be 48.4...46.3??? These values have been consistent for quite some time. I believe that difference is just over 4%, just barely. If I'm not mistaken, someone (a triumph technician) here on the forum, rather recently, stated the ECM will manage up to 4% discrepancy??? Since loading the 20220 tune [basic tune(with speedo and top end adjusted] I've gotten a significant increase in decel popping. I may apply the decel mod to this tune before trying to run a previous era base tune with the decel mod add-on. I've not had much success with earlier tunes and the latest TB versions. I'm not sure it's not operator error.
Thanks B, for the link to the TPS adjustment instructions. The TPS voltage has been out of whack for as long as I've had the TuneBoy in hand, to check it. Which has been almost as long as I've had the Rocket. Coincidentally, fuel mileage dropped from 39 to 34 very very early in our relationship (it was no fault of loading enhanced tunes via TuneBoy). I attribute the very early on drop in MPG to the change in the TPS voltage. Is this likely???
