so, that's the story, after i've installed the decat and the power commander 5 ( all from badwinners) on my vitpilen 701 i noticed that the easy shift now don't work well at all, it's hard and it gives me some problems changing gear... i don't know if this is a problem of my bike or the delay and spark timing created by the pc5... somewone can help me?

and another thing... with the power commander i installed the O2 sensor elimitator ( i have not removed the evap canister and sas valve) my question is... it's safe to go with a "blind" bike? what i mean is that now the closed loop is not working anymore and so the bike is blind on the afr... and i am scared that one day it will lean out tooo much and it will break...
 
The quickshifter briefly cuts timing for shifts. If the pc5 alters timing . Then that would affect it. One reason I don't trust power commanders is that they delete the 02 sensor. If tuned properly for the conditions you ride in normally it shouldn't be a problem. But if you drastically change conditions issues could arise. Stock maps are less aggressive to provide a little leeway. And still have the ability to self adjust slightly. You're kinda locked into whatever tune you have on a power commander. Unless you get the autotune add on.

Is a good idea so to buy the autotuner kit for my power commander? If so how it works
 
If you have the money . It uses a wideband 02 sensor( the kind that Dyno tuners use much better than stock narrowband). To constantly adjust a/f as you ride .

I don't know... It costs a lot of money and I need to solder the new attack to my exhaust pipe...
But I don't know if buy that or to take it stock again... But stock is a bit bad to drive and it runs lean.... And still for my knowledge it uses the closed loop only under 20% throttle and 5500 rpm...

What is the right thing to do ?
 
A decent exhaust shop would be able to install the larger bung in stock position. You could get a Dyno run.To see how well the pc5 is running and discuss it with them. Or just run it as is and take the chance. I doubt it's a large percentage of failure but it's not zero .Personally. I just go with mods that add a bit more fuel to stock or lightly modified bike. Like fuel x or O2 sensor mod. Or boosterplug .

So you think that the best is to take it stock? But stock from what I know it only uses the O2 sensor to tune itself in a very narrow way..... So it's like is not present.... I can be wrong so correct me If I say something wrong.
At this point I think that the best thing to do is buy the autotune kit, set it to 13.2 to 1 on all the range and install the plug for the wideband sensor

But tell me if I am not correct and the bike will be fine completely stock
 
Stock is a bit lean. ( And so a bit snatchy)But by design. It when you start adding other mods like exhaust and air filters and altering fuel and timing. It can get exceed stock adjustment. I have boosterplug a lot of people have kevmod. Both add just a bit more fuel. A lot of people also run pc5 without issue. So it's up to you. The safest way to run a power commander is autotune. But is it strictly necessary. Probably not. If you stick with the lower cost options that just add a bit of fuel to stock maps. The bike runs a bit better. Without worrying about fuel and timing changes that could potentially damage your bike if done incorrectly. But if you are worried about the pc5 Get a Dyno run. Or autotune

I thought about it for a bit.... So the less expensive thing is to take the bike stock again, remove the air box lid... But I have a doubt, a lot of people say that the best way to drive a pilen stock is to remove the O2 sensor and use the rottweiler fuel dongle... But this will make the bike blind like it is now.... And then the bike will still be blind about afr after 20% throttle and 5500 rpm... What is the best solution for you?
 
You're overthinking it to much. If you have decat and air box lid removed. You are better off with the pc5. . You have more adjustability with it than the fuel dongle . You seem to be anxious about whether it could cause an issue. . just run the bike with the power commander like everyone else does. Most likely you will be fine. But the only way to be 100% sure is to spend some money on the pc5 with Dyno or autotune.
 
To my knowledge the stock O2 sensor doesn't do any real 'tuning', it's just for emissions control.
 
Kinda. It alters the fueling to maintain a preset parameter of engine performance. Mostly emissions related. It does perform a function so it's " tuning". But it most cases it's function is not able to be changed (stock) . So it's not tuneable. Adding various mods can exceed the stock parameters in some cases
 
Ok, I've decided to remove the pc5 because it was giving me problems and I don't know how to resolve them, and because with the decat I am illegal... So I've decided to take it stock.... But there is a way to enrich the afr on the closed loop part? But without removing the O2 sensor?

IMHO “out of the box” tuning is rather pointless…. Every bike, even out of the factory is different, let alone if you or a former owner did “some” tweaks…

I did some minor hardware tweaks in my VIT 701 and we did put it on the dyno…. And tweaked the map… BUT Ktm/husqvarna, do block the closed loop maps to tweak… so we added a Rapidbike easy for the closed loop part of the map..

So yes, that can be done, but imho, you have to tweak the “whole” map, on Your bike, on the dyno, live..

Tomorrow i wil make a topic of my own and publish the dyno runs and outcome.. so keep yr eyes open for it 😁
