I do not get the results from the ecu. It comes from the ETV test equpiment. Much more accurate. It also shows true running conditions and AFR. Test riders put 500+ miles on the bikes before they come back to the lab after any change to the system.

Here are a couple references to the same source, with varying levels of detail. Look for posts by CDN. RG in https://www.hdforums.com/m_3593725/printable.htm and https://www.hdforums.com/m_3533110/printable.htm

I know a complete tune is the correct way to get the bike to run perfectly, but it will cost $1000. $550 for the super tuner and $450 for the dyno tune (the going rate at all the dealers here). Or $650 for the thundermax or similar plus the cost of a laptop (at least $400) (I have macs!)
I don't have $1000 extra lying around to put into the bike right now, but I can spend $100 if these work. All I want to do, is keep my bike from running too lean and causing damage!
What dan I do?
Thanks

BTW, sorry cruiser. I know you asked \\;me to leave this thread 25 pages ago, but Glens has brought alot to the table in the understanding of how our \\;ECM's actually work. This threads greatest contribution to \\;us all, could just be more knowledge about our EFI systems, and how they work. \\;Not to drum up buisness for Nightrider, as it would seem you intended. \\; \\; \\;

Devils advocate........Glens, If our ECM is in fact adaptive, would it not add fuel in open loop equal to what it learned in closed loop? That seems totally logical to me. If it needed more fuel in closed loop, it would most assuredly need more fuel in open loop.

Say you primarily ride in a low population density region where fuel is just gasoline. Then you visit a large city for a weekend, where they primarily sell oxygenated fuel to combat smog. Your ECU will detect, while closed loop, that more fuel is needed to achieve the programmed-in AFR. You will also need that same amount extra fuel while open loop to prevent a lean condition, and it provides it for you.
The problem with this system when used with un-VE-tabled parts is that those parts rarely, if ever, affect the flow through the engine in a totally linear manner, like the different fuel does. The response of the EMS is linear, even for a non-linear change you made to the system. What should be a correct response becomes incorrect because it was based upon incorrect information. The rule of thumb for computers is: garbage in, garbage out. You cannot expect correct output when you feed it incorrect input.
Again, this pertains directly to the *IEDs because when the tune is correct, you are feeding it garbage and it will thus output garbage.
Especially, it pertains when you add/change breathing apparatus without informing the EMS about it, or after-the-fact altering the outputs to compensate with some sort of piggyback unit.
When you combine both, different parts and garbage input, you really are creating, at best, a non-optimal situation. Why would you spend upwards of 20K for something and then quibble over a few hundred as opposed to a hundred to change the way it fundamentally works? It does not make sense to me. Not in the least.
But I want to here reiterate, for the sake of Cruiser, et al, that if you want to mitigate some of the heat of running stoichiometric AFR while you further evaluate your options, and you are running a factory-correct system, the standard IEDs would be a reasonable stop-gap measure.
