Husaberg 570 EFI tuning

Hello from the new home of Husaberg, Austria!

My name is Christian Eszterle and I joined this forum because it is the only one I found where some guys which seem to know something about the new EFI are. I hope you can help me a bit ...

Please don't get mad if there's already a thread for it ... I searched with Google and in this forum for hours now and didn't really find clear information ...



I'd like to get some information about the new EFI on the Berg. I'll try to give you some information I've gathered about it (Just for information&control purpose) and then ask some questions ...

Information ...

- It seems to always run in open-loop-mode except low-load cruising where it should run in some kind of closed-loop
- Only the fuel-maps are adjustable and this only after a dealer loaded an adjustable map on it
- The ignition-tables are not adjustable no matter what (?)
- Till 6% it uses the RPM and MAP-sensor and from there on it just uses RPM and TBP
- No logging of ignition timing and A/F and those kind of important things possible, at least with the UST
- There is a dealer-tool which can load new ign. maps but can't change em
- There is a P&P ECU from "VortexCDI" but it's quite useless since it's not adjustable



Now my questions ...

- Is there any possibility to change the ign. tables?
- Is there any ECU which is P&P and fully adjustable&logable?
- Did someone already reverse engineer the original ECU?
- Would it be a big deal to just install an other EFI which is fully adjustable? (e.g. Ducati ...)
- Could I run a 570 with E85?

Maybe you already see where I'm aiming at ... I'm thinking about getting a FS570 instead of my FS650 but it should then produce at least the same power, rather more. I think this would easily be possible through a 610 bigbore, bigger intake and especially E85 with a fully adjustable EFI.

I've already noticed that there are some cracks on this forum which already mentioned some things about the EFI but do you know some real cracks/reverse engineers who could make things like fully adjustable original EFI possible? That would be really great and would make some real power possible!

Thanks a lot!



Kind regards from Austria!
Chris

Welcome to the forum. There is not too much EFI info on UHE yet. Hopefully more will come. User Tachoacer seems to know the most regarding EFI

The 2009 models have an oxygen sensor and the 2010 models do not have an oxygen sensor. So the 2010's are definitely Open Loop. It has been suggested on this forum that the 2009 oxygen sensor is disabled so it possibly is Open Loop too.

The Husaberg does not use a Cam Angle Sensor so that may be an issue when looking for an aftermarket P&P unit. I have not had a look at what pulses come from the Crank Angle Sensor, but that would need to be checked too. The factory setup seems to run faultless and smooth. Interesting to note the Fuel injector must fire every cycle with no Cam Angle Sensor (instead of every second cycle as per a normal EFI setup).

I think Tuneboy is thinking about Husaberg EFI

Not yet but stick around UHE, I am sure something will come out within a year.

I find it hard to get excited about a plug in EFI module with screw driver adjustments. Maybe it is sensational though, I have no idea

Thanks. I've already mentioned that. But it's also not really usefull since there's no possibility to change the ign. timing and no logging, at least there was no logging due to a lack of available software. Maybe there is one now. But still ... It doesn't really look that good for me ...

I'm thinking about putting another EFI on it like a Ducati. There is a swedish guy I know who just made a DOHC-head for his 650 and put a Ducati EFI on it without problems. Maybe that would be a solution. But maybe the ign. would make some problems ...

Would that be the user Dr_C on this forum? Here is his post:
viewtopic.php?f=30&t=11773

Dr_C is using Megasquirt with Innovate LC1 Wideband O2 Meter. I have an LC1 on my boat and it works great apart form the water buggering up the O2 sensor after time.
Innovate also have some neat looking logging tools.

I can't see any Doco in the program or the zip file ?

Exactly.

Yes, I know about the Innovate LC1. I've heard good things about it but more from the Mitsubishi Evo Tuning.

To be honest ... I already heard about Megasquirt but didn't really inform myself about it. I just read it and this sounds REALLY good! The Controller should be able to talk with the EFI and hopefully with the ignition so everything would be fully adjustable? Would also be quite pricey.

Don't worry ... You can download it at the HSB page ... (Main page --> Service --> Downloads --> Somewhere there)

Re: Husaberg 570 EFI tuning

Husabergs and Evo's. I see we have something in common. I know what you mean. It sucks the user tool can't data log the A/F ratio. I wonder if there isn't an open channel that could work for this. The UT does change ignition timing on the KTM's and it is the same tool. I have e-mailed both Tuneboy and TuneEcu about the Berg Keihin ECU but no response. I will have to get something fast though cause Saturdays dyno runs showed I'm real lean. I use the Innovate also just haven't got around to adding 12v plug for it. Plus, now with a Ti FMF header it presents a new problem. I have a Ti welder just can't find a Ti bung to weld on the pipe. Until next time, you should like this pic.
