AF-XIED for R1200 LC

[Tractors are go]

I get that totally, but then the people who have had invisible cream swear they can feel the change just from the riding experience. But that objectivity is questioned hence why I asked.
But ultimately the only person that needs to be satisfied is the rider I guess.

It is not objectivity, it is subjectivity. However, perception is also reality.

If you think that your bike "feels" better then surely that is all that matters ???

Now as too the af; Roger has done a lot of research/monitering/investigation and I have asked questions, which have always been replied too with courtesy, as I am curious. Not to slag off, criticise or proclaim him a false god

The saying lots of ways to skin a cat, springs to mind.

There are many different ways to improve/resolve/fix what some perceive as a fault with their steed.

... Roger, you are clearly expert in this area and people respect your knowledge and opinions, however you have contributed numerous times on HT threads about AF-XIED's so I don't think you can complain when the reverse happens

...

Fair point, and these are community forums so they can be what we collectively want them to be—within the constraints of the mods.

I remain interested in what it is that HT actually do to the motorcycle and would prefer to hear it from them. To date, they’ve kept it a black box—rare these days, but their prerogative.

Totally.... the value of anything is only meaningful to the person using it. The foggy bit is what “it” is.

If “it” is genuine then hats off as it’s very clever but a bit more water needs to flow under that bridge before the waters clear.

The effect of the AF-XIED is indeed possible to show on a graph. However, a Dyno is not the best way of doing it. The BMW LC engine is already fairly well fueld at WOT, so extra fuel on top of that again will have little to none effect with respect to gaing more HP, the extra fuel at WOT will however contribute to slightly cool the engine, so it is not a total waste.
The Best way to tell the difference pre/post AF-XIED (as well as any other tuning that works on extra fuel only, and doing nothing to fill the cylinder with more air) is by seing the graphs of the AFR, and there you will see a clear difference, no doubt...
Since I'm on vacation now and lack the ability to find my documents I can only point to a few pages back in this thread that shows the difference before/after an AF-XIED is installed. The recordings where taken with no bias and are for real, and the show how the AF-XIED works.

Lads, slightly off topic. A question for the technical people............is it possible that a bad/faulty/failing battery would have a negative impact on the performance of the AF-XiED units??

According to the data the AF-XIED hardly draws anything when bike is running, and nothing when bike is off, so even if battery was failing there would still be enough power for the AF-XIEDs to do their job, however would a failing battery affect other electronics on the bike......

Basically, I put a new battery in my bike a few weeks ago and it has transformed the bike....... I now realise how bad it had been running.

I just figured that maybe the bad battery was causing the AF-XiED units to fuel the bike badly.

Either way...... I'm back to being a happy camper.

Cool, hence my post affecting other electronics, ECU etc...... these new bikes with all the electric wizardy only has one major problem, if it has no energy its screwed.

Could that be because the ecu has re learnt the TPS parameters. As per my post yesterday I did that reset and noticed a difference

I don’t know the internal design exactly, but it’s my understanding that there’s a 5V regulator for the electronics so it should be insensitive to any battery voltage as long as it’s above 8V.

Well gave the bike a good thrashing this morning in Dynamic mode only, and them vibes that I have in Road mode are simply not there, the bike acts like a beast, really a totally different ride to Road, I have been using the Dynamic mode only when solo but not for a full test like today, it is the way the bike should be IMHO, however the Road mode is comfy for the 2 up riding, so basically the AF-XIEDS might just make the Road mode feel more like Dynamic mode, and the Dynamicic mode can be renamed, Dynamic beast..............

When I first bought min a year or so back, that vibration (3K-4K revs in 3rd/4th gear) was intrusive and very noticeable, and the bike felt a bit snatchy at low revs, especially in road mode. A year on, with many thrashings later in dynamic mode and the bike is transformed. No other tuning done. I guess that the previous owner just had a very different riding style and the bike has adjusted to my style. I try and ride smoothly and within the limits but am not afraid to use dynamic road at WOT for overtakes and up the gears. The low revs snatchyness has vanished. Either it's my imagination or the bike ECU has adapted to a different riding style and perhaps fuel (I use super unleaded when I can).

I forget if you have a gs-911, did you reset adaptive values when you installed? It’s not really necessary, just curious.

The more you ride at steady speeds, up and down hills, at various speeds and in different gears, the faster the adaptation will propagate to the 20% of your fuel map not covered by Closed Loop.

No I do not believe you are imagining anything, the bike in simple Dynamic mode is brilliant, like I said I do mostly 2 up and had not really had the chance to give Dynamic a real good thrashing, and it is awesome, if I rode in this mode all the time, I certainly would not need any tuning or even AF-XIED for the matter the bike rides so good, just hoping when I finally get my AF-XIED,s they help the more sluggish and more Viby Road mode feel nicer, and if they do as I am fairly certain they will I will be even more happy.

I have not done anything to my bike Roger it is bog standard, I still do not have my AF-XIED,s yet, however this has really got me thinking that maybe if it is possible, and surely someone will say yes or no later, the Tuning companies might just copy the Dynamic part of the software or the values over the top of the Road mode, so we see Rode mode on the screen, but we are not really riding using Road mode values, It just seems so easy, hence why an automatic feeling of being cured, as the difference is massive, however I cannot comment on fuel consumption, as I never ever look at them figures, even in the car, I just fill up when empty.

I find the flat spot on my bike is worse/more obvious in dynamic mode, so much that I just don't use dynamic mode

I can see that as a possibility but to do so they need to break the ecu protection via obd. Other than the rexxer method of cracking it open I’m not aware of anyone breaking in via software.

Got it, my bad. What’re customs doing with your kit, making a copy?

Have you tried the TPS reset method at all.
