what other bikes share the Fi set up that we have does anyone know? I haven't checked anything out but do ask aloud.

maybe others have worked hard at their Fi and ignition programmes/maps?

I've been speaking to a roadbike specialist in this field and the first question was: who else uses your system? I figured it was the usual suspects at sherco, beta, ktm, tm? i believe that husky are with mikuni. that still leaves the jap 4 as well?

My KTM 990 uses Keihin EFI. I've been using Tuneboy to tune it. The Berg has the same ECU connector so I'm trying the KTM software thru my Tuneboy cable. Seems I need to find a way to keep the Berg powered up.
I've played with the Honda programmer on CRF450's and it seems like it was Keihin also. Getting old. My memory sucks.
 
Sure would be nice if someone hacked these damn things.....

It sounds like it is proprietary for the bergs. Even if you get the user tool, you still can not load the curves the shops can load, only tweak. If you go the tweaking route you are looking at some serious dyno time to get it better than factory (or so I have been told, by someone in the know).

I would LOVE to be able to play with different curves like on my Montesa or the CRF.
 
Triumph use Keihin too.

I live in the same town as Tuneboy (he drinks at the same cafe :) ) and he is thinking of tinkering with Husaberg EFI. I am hoping to get on his Dyno in the next couple of months.
 
The EFI hardware and probably the firmware must be common to many other applications. Can't see why a large company like Keihin would produce bespoke parts for one particular machine especially a low volume manufacturer like Husaberg. What will be specific to individual machines will be the software or MAPS. JMO

It is bespoked by the fact the data to and from the ECU is unreadable by most mere mortals.

tahoeacr, If you bridge a wire between pins 5 and 6 in the XC1 connector the Berg will stay powered up.

thanks Davo. I tried the jumper tonight and worked just fine. What I am trying to do is use my Tuneboy cable with the download software for the user tool. The Tuneboy cable uses 3,4 and 6. I would need to jumper on the back side of the bike's plug. In the desire to save $600 on the user tool and the order time I will probably fry my $440 ECU :D .
 
Kawasaki KX use the same Keihin FI as we do. In fact, the programmer is the same and their manuel is much better from what I here.
 
Forgive my blind ignorance of OEM tuning- I come from the dark land of mega squirt. I have been back tracking the OEM system timing and parameters to get off the OEM hardware and go to a MS box with full, no BS, control.

All you are changing in the ECU is the registry map of injector timing and duration based on RPM and TPS, correct? And possibly ignition timing if available? So in function you are just overwriting the EPROM (hex table?) in the OEM ECU.

The factory "tool" is just the HMI gate keeper/secret decoder ring to the memory location of the tuning tables??? If I but-in and sniff these I should be able to see the shifts in data (line by line comparison) as different parameters are burned? I am currently directly sniffing injector, TPS, ignition, and crank position and backing that into a map as a base line. I am holding off of getting the Berg tool because I can get a spare standalone controller for the same price...
 
I haven't gone into any of this yet but I think that all they are controlling is the ignition timing? maybe something else small or trivial?
