Kuksul08, I'm having some sputtering issues when trying to stay a steady speed between 3500-5000ish. What would you recomend I do, increase or decrease or autotune? Your help is appreciated

You may need to check the fuel tank line to make sure it didn't get pinched when the tank was reinstalled.

Yeah good call on the fuel line.

Also when in doubt you can always load a zero map (all cells are 0) and it should run exactly the same as before. If it doesn't, something is up.

Checked the fuel line ....and everything else. Took it all back apart and inspected everything then put it back together. Still had a terrible tremble from 3500-5500 while holding a steady speed . Holdijg a steady speed any rpm between that spectrum. Contacted rapidbike and they were very helpful, they suggested adding fuel at 10% between that spectrum. I did and it helped. I added a little more and no change change. Contacted rapidbike again and they recommended they go in remotely through my computer. I was extremely excited that they could do this and happy with how helpful they were being. I emailed back saying that I would like to do that and gave contact info to make things easier and was flexible to whatever time they could make for me. They responded days later "please dont mess with what you read or see online". end of conversation. I thought we were going to do the remote connect and help do a little more tuning than just a base auto tune. It appears as though we are not So I just said F@# it and turned on auto tune and it is smoothed back out. I kind of got the system because I wanted adjustability. Oh well, auto tune it is.

Araitim,
I recently got the 3500-5000 rpm sputter. Thought it might be bad gas since I recently relocated to Italy. I dumped a can of Seafoam in it when I first had symptoms and it seamed to work. Still comes and goes but what I have noticed is that it runs very smooth when cold - 125 to 160 degrees. Once it gets to normal temp (hot now that summer is here), sputter returns.

My starter is almost dead and it will short cycle so bad sometimes that it cycles the power to ECU. My gear indicator will go to null and once I got "errors" message. I'm thinking that it scrambled the RB settings. Will probably dig in software and try Kuksuls map this weekend.

I hate when people say "don't listen to what you hear online". Sure, wading through a lot of internet trolls and anecdotal evidence is a skill to be acquired, but there is a lot of good logical information out there. We are lucky to live in this era where you can become an expert in anything if you're willing to read enough and have a good filter.

The guy in Florida is not Rapidbike, just a distributor. He went into my map via remote connection when I first was learning how to use it and went through the map manually changing numbers so that it 'looked' smooth. Based on my own measurements using a wideband O2, whether or not the map "looks" smooth has nothing to do with its actual performance. I have adjacent cells that jump several % and the bike runs perfectly. Sadly we don't have any contacts with the engineers at Rapidbike, which is why I will be using Power Commander in the future since they're based in NV and more accessible.

I will say, no matter how much I played with settings I never had extreme stumbling or what I would consider ridability issues. It was more like trying to perfect something that was only 85% refined. My main issues were inability to maintain constant speed at 4000 RPM, and a dead spot at 6000RPM. Both were fixed with the tune.

I suggest trying the map and settings I uploaded. Especially be sure to change the columns to start at 2%, not 5%. This is probably the biggest factor. Cruising at a constant speed only has the throttle bodies open 3-4%. Worst case you just revert back - nothing is permanent.

I dealt with that FL dealer. He didn't want to talk to me because I bought my unit off eBay for much less than he charged (only one in US that sold them at the time). When I provided proof from RB that it was legit, he started talking.

I'll be loading that map. I could have a pinched main fuel line or clogged filter. Had the fuel line issue in the past after install and I've ridden through some dirty African monsoon storms here...left the whole bike caked grey.
