Ivanís reflash or Custom Dyno ?
« on: April 04, 2018, 05:26:25 pm »
Hello there Bolt lovers,

I have a 2014 model XV950R, the Bolt R-Spec, fitted with a Vance&Hines VO2 and a Falcon Slip-On exhaust. My question is, do I send my ECU to Samios in Greece or do I go to my garage and do a Dyno set up?

What do you this is the advantages in each case?

Thank you :)

Hello mate,

I have no answer to your question since I have not tried any custom Dyno runs.

What I can tell you is that I've got my ECU flashed by Samios, and since I own 2017 (Euro4) model, there is a slight problem (could bother some, I personally do not care about it).

Engine red light on speedo will stay permanently on like there is an issue with the engine.
It is only for latest 2017 model, and not going to happen to your or any other model before 2017.
Has something to do with O2 senzor bypass and they are working on the solution to put that lamp off.

With that said, flash made my city low speed ride in 1st, 2nd and 3rd gear much smoother and I would keep it just for that (not going to revert flash even if that lamp stays on forever but i still believe it is going to be fixed).

Not sure about the power gain since I did not do mods or flash chasing HP and did not bother to check, can't remember I ever wished I had more during my rides, but I only have 5000 km on it so far.

I am about to install Cobra intake today. Mostly for looks, but flash is said to be aimed at higher air intake anyhow so it can only get better power wise.

I do have question for you though, how good is that Falcon muffler? Any chance you can write differences in terms of sound depth and/or loudness compared to stock?

And if you got an opportunity to hear the difference, how does it compare to Arkapovic or Miller (both street legal in EU same like Falcon)? I know how those sound so I might get an idea about Falcon if you heard any of those and could comment on it.

I can't make up my mind yet as I like the looks of them all TBH.

Thank you, but video is not enough on my questions.

It's kind of subjective opinion that I seek here (opposite of usually wanted I know :)).

I kind of wish to hear your perception of Falcon in style, sound (both tone and loudness) and value for price payed. Almost every other slip on is described in that way here on this forum except Falcon so I am curious. I am leaning to the Miller Avenger for now, but would likely consider Falcon too if I got more info.

Also I have installed the Cobra intake kit today and I can feel the difference, it opened up a bike quite a bit and I think it's similar if not same filter as in your V02.
 
The only thing that surprised me a bit is how loud that air sucking is while bike idles in place, how in the world did that old intake hide that? I could swear I did not hear any air sucking at all while standing in place with original intake altho I did not ride for a month so maybe I forgot :D

I like the sound and style of the Falcon. Today I rode a ScR950 with factory exhaust and the Falcon sound is more loose, more powerful, more meaty. Sexy sound in my opinion.

Now this may be different with the Euro model but it sounds like the same problem that us in the States get & here is the solution...
I've had my ECU flashed & the engine light also came on. There is a simple fix however. All you need to do is connect the O2 sensor for a little while till the code clears. Once it clears you can then either unhook it, which others have claimed the light has never came back on, or keep it plugged in since the flash is suppose to bypass the O2 sensor anyways, Ivan said it shouldn't matter. Hope this helps with clearing your code

Yeah, I'm not sure this is the same thing, as the reflash has changed somewhat in recent years, and Ivan now advises that you don't ever have to remove the O2 sensor in the first place now, as the flash simply ignores it completely.

I'm guessing Cygann is like me, and has had the reflash, but never touched the O2 (as advised by both Spiros and Ivan). Cygann - I'm having same issues as you (2017 SCR950) - I'm going to drop you a PM.

One thing I would like to try - although Spiros says it won't make any difference for this particular issue - is actually disconnecting the O2. I also need to do it for my new pipe that is arriving shortly. Can someone advise on how to do this though? I have seen elsewhere on here that people find it a real pain to disconnect. I read a small, flat-bladed screwdriver assists, and I've slid this under the 'top' cover, but still it won't disconnect. Are there catches on the 'sides' of the connector that need holding in at the same time? I have a feeling I need four hands!

Any advice grateful received.
Ben

Hey Ben. It was difficult for me to disconnect also the first time I tried it. But after I figured it out its very easy. Most connections like the one on the O2 sensor you push the piece in(the connector release tab or whatever its called). Not with this one. Instead pull the tab back while pulling the connector apart. Hope this helps

I'll give that a go then - thanks for the quick response!!

You can watch this 2 videos ;)

Great vids on exhaust etc, at least it gives you something to build on as per personal sound you're looking for in your ride.

Hi @SCRBen - did you ever get this fixed. Samios has very kindly responded today saying that they can't support Euro4 - which is a shame

thanks
