PSA - TuneECU might have a weakness on 2014+ R3s.

I've got a 16, can confirm that you can flash tunes to it fine with TuneECU. My question is though, is this drop off at 5800 still an issue? I used put a slip on on my bike and used TuneECU to flash the standard Triumph TORS tune, I was concerned about running too lean. Should I be concerned that I just gave myself this issue?

It does work ok on 2016 bikes. I've not been able to confirm or deny the ability to tune out the fuel cut as I switched to Tuneboy in frustration, and I've not seen anyone get a pro done dyno tune using only TuneECU or the resulting map to determine how the tuner might have fixed it. I will say, the stock injectors are without question not the cause, it's a software issue.

I would highly recommend paying the money to have it tuned on a dyno. Even with the hours and hours of time I've put into tuning my bike (bikes), 45 minutes on a dyno in the hands of a good tuner made improvements on power delivery, smoothness, and gained a little power up top. There really, truly is no substitute.

Pretty sure @1olbull only uses TuneECU for his dyno tunes.

His is a pre-change bike, it's the 2014+ bikes in particular that I've seen this issue with.

Much of what applied to pre 2014 bikes doesn't for the latest version, thus my search for how to convert my bike to the original Roadster configuration.

Didn't think of that.

We really need some more TuneECU tuners in this country. Long way from Texas, soon to be Florida to Washington to get mine done.

And I'm curious, with the installed base of TuneECU maps that aren't yours, where are the other complaints ?

Are we destroying our engines without realizing it ?

Joe,
I suspect the vast majority of 2014+ roadsters will dyno exactly like the one on page 5 of this thread. The reason it's not doing damage: The R3 isn't a knock limited motor, meaning, its basically detonation proof in stock configuration and that 5800-6xxx part of the rev range goes by very quickly and only swings into the high 15:1 AFR range. Survivable for our motors easily.

The ONLY reason I found this anomaly was that I had my LM-2 gauge showing AFR one day when I decided to explore the big end of 5th gear and happened to glance at the gauge at over 150mph and it was in the 15.5:1 area so I immediately let off. Since that happened I've noticed a number of dyno's posted with the same lean swing at 5800+.

There's no way to notice it without a wideband/dataloger, something very very few riders use. To answer the riddle once and for all we'd need someone credible (neville would be the best source imo) to detail their experience with only TuneECU on a 2014+ bike.

Im tempted to transfer my TuneBOY tune into TuneECU manually and take it to Nev and see if he has the same issue on the dyno.

There are other undocumented "features" of the 2014+ ECUs that weren't present on the older roadsters, Nev found two of them without me saying a word the day he was tuning my bike. He came out and mentioned them to me, so it's not just me, they are there but safe so I won't muddy this with them.

Anthony come up here - I gots a spare bedroom for ya and I'll take you to Nels!

I appreciate the offer. When does weather start getting bad in those parts? Next 4-6 months are going to be pretty busy for me.

Working to get a little further into the mystery I've just compared the 20228 vs 20776 tunes. The 20228 tune is significantly richer, in both F and L tables almost everywhere in the map. Since we know the R3 internals are identical functionally across all models/years and we know they basically dyno the same given the same mods, my conclusion is that Triumph adjusted the fueling for mileage and emissions.

There are other notable changes as well, more timing on the older tunes in the I3 tables, quite a bit more in some spots, matching the richer mixture in the fuel tables.

The bizzare L tables in the 20355 and 20776 tunes are quite a bit different than the older tunes.

The secondaries do some crazy crap in the newer tunes at high RPM in 4th and 5th gear.

This last bit is where I think things go awry. Even with secondaries removed and a ton (30-40%) of fuel added in the F tables, mine still swung lean. That's what led me to posting this thread originally. It may just be a matter of adding even more fuel up, I'm not sure.
