Actually - on it's own it does SFA. Somebody has to tell it what to do. Their criteria is all!. ime Dynojet's "maps" are shyte.

Anybody who understands "creative misguidance" - aka Marketing - is lying!. Or very effing rich.
Pcv works very well on both 790’s I’ve had, still waiting for the engine to explode tho.
 
2 full years after launching this model and there is still so much smoke and mirrors surrounding this bike, add-on fuel systems or ecu-flashing devices, etc... that it's making my head explode.

How is it that tuners have data, dyno runs, and seemingly endless info on AFR's and such on practically every bike out there EXCEPT this 790? How does KTM "build this engine to 99%" and leave nothing on the table due to emissions or whatnot when every other manufacturer has to choke up their bikes so much from the factory just to pass Euro 4?

I've never seen such contradictory info either - "PCV works great!!!", "Coober is the only solution!!!", "No decat/We have a decat system that works!!!"

Frustrating to say the least for buyers like myself that will happily pony up money for a known/proven product - especially if it'll improve performance, drop weight, make the bike run cooler, etc...

My bike has a decat/PCV/autotuner and once it gets a little warmer outside, I plan to run it on the dyno to collect another dataset for everyone.
 
But who told it what to do? - This matters more imo than it being a PCV.
In my case it was the stock Rottwieler map ,then followed by tuning on a dyno for an hour to fine tune The Rotti map.
My bike works great, no complaints. Stock exhaust though, don’t want or need a noisy exhaust. I already ride like an ******* don’t to attract attention too myself.:)

with check engine light on?
o2 disabled?
 
If you consider that timing is at 99% then the engine is at 99%. 85-90 was 30 years ago with japanese bikes.
Except we KNOW that COOBER messes with the timing. And imo (from observation of my COOBER'd bike) - without the stock ECU realizing.

And when Rottweiler uses the PCV to ONLY modify timing - they make gains too.

Why? - I suspect KTM has it dialed back for some of the more "noise" stringent places in the world - Switzerland for example.

This means there is more in there - but they are making it hard to get it out to avoid other Euro5&6 issues. It also explains some other choices like final gearing - which imo is NOT optimal for road use. imo a bit tall.

Waiting to see what MyJet nr Vienna announces. They have a kit ready from all accounts, but they (Engineer and wife) are on Holiday (until 19th Feb iirc). Simple old fashioned trial and error tuning using a Dyno.

The entire R&D process with failures and gains is on the German speaking site as we know.

No idea what is in the Kit - Almost certainly an airbox and lambda dongles. I am on their mail list for the announcement. I doubt I will do the conversion, but will be interesting to see.

ime - The COOBER is semi-adaptive. I say semi as the changes it makes in flight are not stable for a couple of 100kms. This was obvious when I whipped the dB killer out of the WINGS. I know "look forward" to it re-adapting as I have stuck the dB killer back in.
I love how the engine feels open - it feels sort of looser. But the noise is too much - in the city it makes policemen's heads turn. And I think a long run with it open would become tiring (even with earplugs in).

ime - The PCV with A/T is equally semi adaptive. I've been using it for the best part of 6 years on the Big Triumph.

imo - To really know what is possible - the best way would be ditch the Bosch ECU - get a bonafide race ECU (Like Megasquirt) and go for it. Cheap? - No!.

I was not able to see any diff on my engine with the coober on timing, but based on their info they calculate it more often then stock.
Also the reflash guys do not change anything on timing. Because if the engine hits a certain heat point, it drops down timing up to 7 degree. You can clearly see on dyno, even on can log

I am following them to, but they did not made anything in last 2 years. there are some pictures and charts online but no serious results for now. I have seen they are developing on the old 001 ECU software. Most people have the 002 or 004, this was requested by some guys in the forum but no response.

This works on my Akra muffler also. No idea how they do this. You can clearly feel the difference with dbk and without. On stock ecu there is no difference.

The biggest problem is, if you can not dissable the 02, A/T is useless, so you can only manage 6500rpm+ does not make sense at all.

Based on cober facebook posting, the Bosch does use fuel correction torque map.
This does make sense, so if the injector is out of the specific range, the bosch ecu simply goes down with torque.
My BMW s1000 did this also few years ago.


There are some French and German guys doing the 800cc cup. Few of them use dta ecu on their 790 Duke, seams to work fine with aftermarket dash, if you know how to wire.
Mega ECU i am not sure, defiantly not on quickshifter and other complex functions.
Not sure if it makes sense or not.
 
Yes the engine light stays on and the o2 sensors are disabled.
Check engine "ON" means, your gear based mapping is dactivated and you are in so called "protection mode". So you have all gears in one map setup, i am not sure why someone would do this.
Also your drive modes is disabled (only the Throttle opening speed configuration per mode is active). Making the bike worse, to be able to run a external product, i guess i am missing a point here.

I guess you are.:)

Tango - can you please clarify what else is affected in drive mode disabling, other than Throttle opening configuration?

QS speeds? Braking/ABS intervention levels? Max Power output?
