My non-technical understanding is: the effect is at tickover and very light throttle openings when engine is not under load. Light throttle when not under load appears to be where people suffer the dreaded surging.
The surging may be occuring because the system is switching between open and closed loop at this point, or it is running borderline weak.
The techlusion adds juice only, so it feeds the weak mixture area and stops the surging. It also adds juice where the user defines in the range which, when it is set right, gets rid of any emission based flat spots allowing the engine to rev through this point cleanly. This gives the motor the chance to rev freely without any hesitation, hence the increased seat of the pants performance. The cost is increased mpg. This affects riders in different ways. If they tend to ride their bike in or around this rpm area they may notice a significant increase in mpg. Others see an increase but not enough to be bothered.
Adjusting the throttle position sensor is not difficult. A simple DIGITAL multi-meter and a bit of fine wire is all that is required. The effects, especially if the TPS is set on the low end of the tolerances can be quite noticeable, showing a much better throttle response and pick-up.

However, I am usually wrong so feel free to ignore, heckle, tack the p1ss, whatever

That didnt come out right, what I meant to say was:
If the existing setting is at the low end of the tolerance scale, by setting the TPS to the high end of the tolerance scale gives better pick up and throttle response.

Me talking bollox as usual

Clear

Great well thats cleared that up then !!



I agree with KTM as it looks like he has cut and paste from the techlusion site.

OK then, love a challenge.

The moronic system is based on both open and closed loop.

Closed loop - This only happens at tickover or at "highway cruise operating range" (which is the same as "very light throttle openings when engine is not under load") In closed loop mode, the system takes readings from the lamda (oxygen sensor) and sets the mixture to a fixed setting of 14.7 to 1. this only happens at tickover or highway cruise. These are the only two times when the closed loop system is working.

Open loop - this is employed at any other time. In other words, wack the throttle open and the closed loop system is ignored and the moronic starts taking its instruction from a pre-set map built into its brain. So it ignores the lamda sensor and just uses pre-set fueling. Your bike will still run without a lamda, infact BBPower tells its users to disconnect it altogether.

Techlusion R259 allows you to give the bike extra fuel across its rev range by adjusting 3 volume screws for different parts of the range. So.... if the bike is surging you can add juice where it is needed cos its surging cos its running weak.

OK? If that didnt make sense then there is always this fallback:

It goes, suck, squeeze, bang, blow. and remember, righty-tighty...lefty-looseny

Well said, Panzer. My interpretation wuz that it only used the lambda for tickover (or very small throttle openings). Your answer is much more concise.

OK..........having read this post (and other similar related posts numerous times over and over) I am still trying to get my head around it!

Mine is a twin spark model, I have had a Remus y-piece fitted for the last 2000 miles, with no problems at all.
I have had a Remus Ti Revolution can on order for the last 4 weeks (LRR it still hasnt tiurned up) It is due anyday now, mind you they said that 3 weeks ago!

The can is being fitted for noise reasons only and not for any performance gains, if I wanted to go faster then I would buy a more suitable bike.

I looked last night and like others I do not have a cat code plug fitted either

So why do some bikes have them fitted and not others or is it only the twin spark that does not have them as an OE fit?

The cat code plug is region / model specific. If a bike is set up for Greece, say, it may have a different code plug than a bike destined for Holland. Its all down to emissions and regional set up. Also, the electrics are used across the whole boxer range so some models RS/RT may have different coloured plugs which are model specific. Again for the same emissions issue.
Suffice to say, the bike will run quite happily with non fitted as it defaults to a standard setting in the moronic brain. Having non fitted, from my experience, is the best way to run them.
