I have an 09 T100, with NH Togas, snorkel removed and a K&N. I have removed the O2 sensors and SAI, raised the rev limiter to 8500.

I`m running the TORS map, bike seems to run great (I`m happy) and the plug colour is fine.

On the AFR table of the TORS map, the bottom l/h corner which represents approx 0-1300 rpm and 0-10% Throttle opening. This corner is all blue with 14-14.5% values, weaker than anywhere else on the map, I assumed it was a weaker mixture in this part of the table to allow the 02 sensor to control the AFR???

Is that the case?

I remapped and changed those values to 13.9, bike still runs great but smells of petrol a bit. I want to try and get this a s close as possible without using a dyno, any suggestions?

I have a custom map with the AFR table changed to allow for O2 sensor removal. It runs great and no smells.

Have a look at the settings:

can i know the benifit of the O2 removal please?

On my speed triple 2011, i will remove the SAI and the pre cat, but what's the advantage of removing the O2.

And if i remove it, should absolutly run a custom map?

Thank you;)

Will these settings hold true for '13 Thruxton? Have tors, in air filter removed sai ando2.

Thanks
I don't know, the tune map was made by someone else. The figures have to be below 14.50 in the low range, that is below 1300 rpm and 10% of throttle or so. That way the ECU doesn't look for input from the O2 sensors.

Just one question. Is this map used with the stock exhaust silencers? any other mods? i'm considering going back to stock silencers and I would need a new tune. Thank you so much for your help Forchetto!!!

I now have a TTP number 3 tune, but that map was to suit an Arrow 2-into-2 exhaust and mild changes to the airbox, just a Polaris rubber bellmouth instead of the snorkel. No O2 sensors or AI.

Thanks Forchetto! Just for a change I took the predators off and put the stock cans back on. I used the original stock map but I changed some values in the a/f. What I did was changed everything that was over 14+ to 14.5 to a flat 14. SAI and ox sensors unchecked since those things are gone. The bike runs suprisingly well. I figure slightly richer couldn't hurt on a tune thats known to be lean. Do you think I'll be ok with this tune?
