I first tried it with the standard settings for the TDM and with the O2 sensor connected. That was never going to be the way it was used finally, with both EJK and the O2 sensor, because it would defeat the purpose of the mod. Behaviour didn’t really seem any different to standard.
Next step was to disconnect the O2 sensor; again no difference (which just makes me even more certain after making earlier measurements that the sensor has minimal involvement in the TDM brain).
One observation after fitting was that the first LED would blink green at idle. According to the factory info, this indicates that none of the programmed fuel zones are active. So I reduced the Green-Blue setting from the standard 5, and at around 3 to 4 the LED stopped flashing indicating that the box was now in the green fuel zone and having some effect at idle. The performance just off idle did actually improve slightly I think, just a bit smoother. A Green-Blue setting any lower that the point at which the first LED stops flashing at idle probably has no effect, but I lowered it to near the minimum for good measure. Performance at this point was maybe a little better, but not enough to justify buying the kit.
I then increased the Green setting from the standard 3, and at 5 I noticed an improvement whereby the snatchiness coming off the throttle stop was reduced. By that I mean that if you were travelling along in first or second gear with no throttle, then rolled the throttle on, there was no sudden snatch as I previously had. It was also a far better experience in tight hairpin turns and small roundabouts. I didn’t realise that at first because I had learnt to deal with the bike’s behaviour, then it dawned on me what was different. So that is the big leap forward so far: better and safer manners in tight corners. ...Edit: I should stress that riding with no throttle in a corner is not what I do of course!!! - the absence of previous snatchiness is just obvious now from no throttle at all up to over 2k.
At this point I also think that when accelerating, it pulls more strongly and evenly between 2,500 and 3,500 rpm. It’s still useless below 2,000 rpm of course and that’s not going to change. However there may be a little more shuddering when accelerating quickly from 4,000 rpm; still not sure if it’s my imagination. An increase in the Green setting is the next thing to try, or even more Yellow could be a solution to the shuddering.
The green zone is active at all speeds and the only time it gets into the yellow is with a reasonable handful of throttle. So any change to Yellow would not have a huge impact on fuel use in normal riding or cruising.
So the current settings are Green = 5; Green-Blue = minimum. I plan to ride it as it is for a while to get used to it and check fuel consumption, then maybe play some more. But on the basis if what I have now it was worth the money.
