    Hi,

    I have a 2013 Bonnie, O2 sensors removed, Tec 2 into 1 Tracker with baffle in, K&N replacement air filter instead of stock, and just removed the AI. Is it worth having it retuned, maybe get the Arrows 2 into 1 tune downloaded? It seems to run very well as it is, so maybe I have answered my own question.

    Thanks all.

    Hi Tony,imo you have done sufficient engine mods to warrant a change of ECU fuelling map. My advice you is to visit the Triumph Twin Power website and have a look at their range of modified fuel maps. This guy REALLY knows his stuff. I had tune no. 3 in my T100 and it ran beautifully.

    Thanks Dave,

    I haven't removed the airbox, previous owner put a K&N filter in, so maybe a tune no. 1. I'd probably send the ECM to them if I did it, but this is way outside my comfort zone.

    Why not getting it dyno tested and then if ,it needs, tuned. Bit more than buying TTP ,Then it's done for your bike and you'll know it's right. Dyno tune should cost around 180-220 quid.
    Have a look here as reference

    Cheers,

    I have Dave Wood Racing in Aylesbury, quite close to me and I think he gets recommended for his Dyno tunes. Thing is it seems to run ok as is. When I got it it had a K&N filter and O2 sensors removed. Ran fine. I put on a Tec Tracker exhaust with baffle in. Ran fine. I've just removed the AI today, but sleeting so won't take it out yet. It doesn't really pop or surge, but I guess it could still be improved.

    I'd go for a dyno set up.
    All bikes are different and it will maximise the power for the changes you made to your bike and also ensure it's not running too lean or too rich.

    I'm getting lots of quotes back for a dyno tune, from just under £200 to well over £300. I'm not sure it is worth it, seems to run fine as is, so might just do a few plug checks to make sure it's not well out. Then again, you never know how much crisper it might feel if you don't try. New shocks or dyno?

    I would go for a custom map. Ive heard bad things about Davey Wood. We (Jack Lilley race team) always used Dynotech at Bramley, Basingstoke. I know many that have also used them with their Triumphs and are very happy with their work. I have to thoughts on Steve Jordan.

    Thanks Crispey,

    Looks interesting, but I think if I'm going to pay out I might as well go for a proven approach.

    Steve Jordan is looking like the best bet at the moment if I go ahead. I have been told you can just have a dyno health check for £50, but presumably you then just have to pay the full whack for the tune, and I suspect any health check will come back recommending a tune.

    You might be surprised, Steve's pretty good and will tell you exactly what's what.

    I had an Avon tyre, fitted by Steve on a Hayabusa, that wouldn't balance properly.
    I took it back a couple of times with no luck, he admitted he couldn't work out what was up, as it was spot on according to his balancer, so he contacted Avon tyres to see what could be done.

    I ended up going to a test session at Bruntingthorpe with Avon Tyres test team.
    They manually balanced the tyre and it was fine. Apparently, according the Avon specialist, sometimes a balancing machine can be slightly out which won't affect the majority of tyres, but the one I had was one of the awkward ones.
    He balanced it in about 10 minutes.
    After a couple of laps round Bruntingthorpe, I was more than happy with it :)

    Just a quick addendum.
    I hung around for a little while after that watching them do some tyre testing on various bikes.
    While watching, I heard a bike start up that sounded a bit odd, then this mahoosive bike appears from the back of the one of the trucks with a real odd exhaust note and they start hammering it around the track.
    The tyre guy, I'd been dealing with, looked at me and said "Please pretend you didn't see that !"
    This was about 3 months before the Rocket 3 was launched :D
    Apparently they wrote it off about half an hour after I left :eek:

    Interestingly they never use a balance m/c at BSB, SBK or moto GP they are always done manually between centres. When we were racing the wheel was balanced bare. Then the balance mark on the tyre was put there rather than the Valve. Surprising how many times no weights were needed. The TYriumph wheels were not brilliant at their weight balance. The rimstock ones were the worst, the Brembo' were not too bad.
