    Hi, muffler without cat and airbox without lid or with wide open lid, then the asthma crisis ends ! You can do other mods, but these alone will give you 50 to 70% of possible improvement. (European my 19 bike)

    So, you’re making an engine already tuned towards the lean side of things run even more lean?

    Hi, ktm dealer said : take the old evo 1 akra line + powerpart lid, works fine + warranty ok.
    No engine problem to date, no stalling or any other strange thing. The muffler is filled with a little ball of iron wool stuck to the spark arrestor to eliminate huge pops during decelerations. How do you detect that the map is too lean, without any malfunction whatsoever ? Thanks if you have a clue.
    I thought buying a Pc5, but I don't know if it will realy add something, I haven't seen any objective testimony saying that it is mandatory. Do you have any advice about that ? Thanks again !

    Look at the Rottwieler site. They have published dyno graphs before (in the Wunderfest thread?). Basically, they don't require a PC if you just use their intake kit, but the do if you open up both ends.

    Well, rottweiler is a pc5 top reseller, so... I read everything on forums, internet, people saying it's mandatory, others saying that it makes a huge improvement, then 6 months later saying that it's not worth it, others saying that the custom dyno mapping is not working any more when altitude or weather is changing, then videos showing that even in low rpm the afr ratio is still ok. For me as long as the engine is running properly, no need to do further modifications. Maybe my air intake is not open enough, maybe my exhaust is not open enough due to the inox wool added in the tube, maybe one day I will testride a 690 fully tuned then buy the complete story (pc5, wide band sensor, autotune, full open intake without oem airbox...). Still waiting for something really convincing.

    I will say there is a noticeable difference between road vs off-road mapping. Offroad mapping the 690 felt way more responsive while riding on the street. It sure gets hot. It’s clear the stock muffler has to go as well as removal of all the power robbing emissions stuff.

    Without an o2-sensor constantly checking the exhaust fumes, one has to rely on more crude options; checking engine temperature (is it running hotter than previously?), spark plug color.
    The easy way around this is to just run an engine map which is specifically developed to fit the current mods of the bike (exhaust, intake, cam, etc.).

    Check out this video - Chris states that a PC5 isn't required when both intake and exhaust are changed, but does recommend it for maximum performance.

    Completely agree with that, sometimes it's not possible to figure out heads from tails reading all the different opinions - I had similar concerns prior to purchasing the vortex ecu.
    Hope you can find a bike with all the necessary mods and go for a testride :thumb

    I don't really disagree, Rottwieler sells PCs. But Wings, Akro, pretty much any supplier will tell you the same story - the new bikes seem to be able to handle some modification but when you open both ends up you need a map.

    So my only point was that Rottwieler published graphs from dyno runs, which is a bit more substantial than anecdotal comments, at least in my opinion.

    It was also KTMs opinion back when map changes were common place.

    It's also my personal experience. I remapped both my 690 and a Hinkley Triumph after I made intake and exhaust changes and they both ran significantly better than when stock (less throttle snatch, and a noticeable bump in low/mid rpm).


    But if you're happy with the way it runs, honestly no argument from me.

    And if you're not, the solution, is easily available - bring the bike in for a dyno run. Then you'll know.

    Cheers, enjoy the bike.

    Hi, one graph to summarize everything I read on the web concerning 690/701 intake/exhaust/map tuning (last engine, no tuning on internal engine parts).
    don't hesitate to correct it if something seems wrong.

    Interesting graph. I'm not sure where you got the raw data, but it certainly looks similar in most respects to what gets posted here.

    It's also similar to what you'll find in the TuneECU thread - most noticeably the experience may of us have had with opening up the airbox cover on the older bikes to get rid of the 3-5k flat spot. Though I would say the EVO 1 mods should give you that bump as well.

    So, i just got my 10' 690 Enduro, and want to do somethinh with it. Anyone got good tips regarding maps?

    Kinda like the silence of the stock muffler, but will probably change it, and go full retard.
    Used for enduro riding.

    Know my way around tuneecu.

    Most of data come from reading pirate racing dyno charts (>20) testing alternatives on 701 & 690, enduro smc vitpilen and duke. Consistent with other data charts found on forums or youtube dyno (apart scale adjustments).

    How does one access and interpret O2 sensor data. I recently went thru an exhaustive poor-running troubleshooting exercise on my 2013. I saw that TuneECU displayed O2 sensor data, but the numbers varied all over the place. I ended up disabling the O2 sensor when I rewrote my igniition map.

    I suspect that the variability in the numbers was due to the fact that the O2 data varies a lot in the course of a firing cycle and the ECU is only sending random samples to TuneECu.

    (I also saw the same variability with the MAP sensor data. I have checked the MAP sensor with an oscilloscope and saw that it indeed vary with crankshaft position.)

    If I could gain some info from it, I could also look at the O2 data with the scope.

    How to read data from the o2 sensor? No idea, unfortunately.

    For low rpm gains, look to the Arrow full system. 4-5 hp gain at 3-4000 rpm.

    Anyone use a Twalcom rally fairing? I'm digging how minimalist they are...

    Power parts airbox lid or modified stock lid doesn't make it run lean (at least 2014-2018 models).

    Sorry, I missed this when you posted it. But you are right, they are now saying that even with modifications to intake and exhaust, the ECU will compensate. This is definitely different from recommendations for earlier bikes, so obviously there have been improvements in the mapping software to allow for this. Considering the lack of ability to re-write our own maps this is certainly good news.

    In the future though, please refrain from posting videos like this, as my wallet isn't capable of staying closed after so much motorcycle porn and a few beers...
