So unless you guys missed it, this recently came available. I've peeked at the stock maps for everything.
Pretty standard stuff, but the 1200HP is the real wildcard as Triumph purposely left power on the table in order to have the engine have similar character to the rest and purposely limited power up top by limiting the throttle from 6500+ to just 80% to give a similar power feel to the HT and force power to fall off heavily at that point.
To get started you'll need an Android device, an OBD Link LX, MX or MX+ and Tune ECU off the Google Play Store
I've tuned my Thruxton R. I have over 40 revisions in the past week experimenting and trying to get it perfect.
I started with a stock 30042 US Map then imported Power Commander tables appropriate for my mods (decat or Headers, slip one, air filter, ported air inlet). These are available on Dynojet's website.
I ran additions and took it for a spin. The left bank was majorly rich, the right a bit lean. Technically within spec of adaptions, but I knew I could do better.
Pulled fuel out of the left until I had it to a reasonable level. Made some AFR adjustments to command 14.1. Immediately fixed any hesitation and snatchiness. Also this change corrected cylinder 2 on its own. But cylinder 1 even richer.
Made more adjustments, removed the throttle restriction up top and readded fuel where it was being pulled after 6500. Now it was obvious it had much more in it up top, relaxed the limiter to 7800. Pulls hard to that point. Stock the 1200HP is limited to 80% throttle after 6500 to force it to have a power feel like the 1200HT, because in reality it has a significantly different personality with the limiter removed.
Then I tackled the heavy popping in Deceleration and reduced it to a pleasing burble with only soft popping from 2-3k where the exhaust velocity really slows down. This was achieved by a bit more timing on decel and a bit more fuel in key areas. I didn't go overzealous because I didn't want to kill fuel economy, as I knew correcting the AFR to 14.1 for my country wide E10 fuel would already have an effect.
Through looking at other stock maps, I've determined that even though they have different numbers, they are generally identical. So I would like to share what I have come up with.
There are a few things id like to state first:
I have over 25 hours and 40 revisions into this to perfect it for my mods. That said, it's not perfect, but I put a little faith initially into Dynojet, but I also saw that they weren't perfect since cylinder 1 was crazy rich. I did work endlessly on driveability though, I'm content with my results.
If you can take my tune and improve, please do so, just share with us.
So here's my tune for the Thruxton R/Thruxton S/Speed Twin. It's easy to build more maps from my work (download your stock map, open mine, and copy my tables and paste into yours)
I built a Speed Twin US and Thruxton S NZ map just from copy and paste of my stuff as they're identical. I verified this myself.
- 900RPM idle
- 7800RPM redline
- 14.1 AFR in cruise and low throttle for driveability (no more stalling, ever again)
- 12.8-13.1 AFR on full throttle
- Up to 35į of timing under full throttle
- Greatly reduced decel popping
- Throttle limiter from 6500+ removed entirely in all modes
- Recurved fueling based on Power Commander Maps
- Recurved timing based on Power Commander Maps
REQUIRES 93 Octane/98 RON.
I hope they my hard work can help the community, but that somebody can also improve upon my start.
