I've got the Termignoni system. It doesn't change much.

Did it include remapping?

I'm sure they stay within published emissions standards.

I want the opened up air filter inlet that supposedly comes with the Termi kit. I can't find it for sale individually on the Corse site or any distributors. Supposedly a shop in San Antonia sells it but for like $125. I've seen posts on another site that says you can get it for $10, which sounds about right.

Anybody have a lead on this?

Hello. I ride a 2013 hypermotard.

1. I have 1 tooth less (14T)
2. I just installed Rapid Bike EVO (200k since installation)
3. I have the Termi high slip-on with UP-MAP

My throttle is also jerky a constant RPM just around 4k. I am hoping the Rapid Bike will cure that once I get some more miles on it.

My previous bike was a KTM 690 SM. Disabled the O2 sensor and increased the fuel using TuneECU. Completely transformed the bike.

I suspect that the aftermarket fueling modules only work at higher revs, and that the stock ECU handles up to around 4K. So adding a Power Commander or similar will not help that low rpm surging.

That's definitely the case with our new Duke 390, according to the forum.

i do not know at HS, but other bikes e.g. the little Honda Grom, Dynojet PowerCommander handles open loop and Dynojet Wideband Commander 2 (this is like Dynojet Autotune + some other feastures), which is connected and controlled to/with PCV, handles closed loop.
So, WB2 e.g. sets AFR to 13.5 instead of 14.7. This works the way that the signal to the Honda ECU is changed so that ECU means it regulates to 14.7 but in reality it does 13.5.

I suppose that Rapidbike with its AFR/tune feature does the same or similar.

my personal opinion is, that the cheaper and simplier and more efficient way is to disable lambda regulation and only use open loop, if possible.

As you mention the Power Commander controls only the open loop, so thats out of the question then

How do you disable the lambda without Error codes?

i wrote it in the thread diagnostic plug for GuzziDiag.
but unfortunatly for our HS IAW7SM ECUs this does not work at time, but will come sooner or later.

I just now bought a Rexxer Evo and got some maps with it..

- without lambda and with open exhaustvalve.
- with lambda and open exhaust valve

but up to now i am not satisfied with engine smoothness, actually i cannot feel much difference to stock. but the files are for termignoni exhaus which i do not have, have stock one.
have to speek with Rexxer guy tomorrow.
i just want a file, based on original one and just lambda regulation disabled.
what they provided to me are files they generated on dynamometer for best performance. but 2 or 3 hp more or less is regardless for me, i want smoothness between 3000 and 4000 with low load.

@ferdi: It sounds like that's the solution to go for.

I'm usually in the span 3500 - 5500 for normal driving. Should I be in a lower gear?

Keep it above 4000 and shell be happier
That said, I'm often down around 2000 in 1st or 2nd gear. I do get a bit of surging, but nothing if find intolerable.
