'07 TuneECU Map reviews and musings

Try one of my maps in this thread. The 2-1 made it run richer. The abrupt throttle shows it's rich.
The 2-1 will also make it un-balanced compared to the 2-2, you may get some vibration in the upper rpm's. That will take some work to figure out.

My '07 (with ~72k miles) has a stock map (with O2's on) and had vibration below 3500 and above 6500 with the stock airbox, KTM branded FMF's, and the SAS and canister were disabled, 16/45 sprockets. PO claimed 40+ mpg regularly. I found the speedo to read a few MPH high so I switched the tire diameter setting to 19" and now it's spot on. My first three fill-ups were all 40-41 mpg so I figured it must be running right in the cruising range at least.

She is new to me, never had a v-twin before so I didn't know if the vibration is just inherent to the design. It wasn't really that bad, plenty of power but I rarely reved past 7000 rpm because it just didn't feel right to me.

For a winter project, I just changed to a Rottweiler intake and fabricated (with help) a 2-1 pipe with a chambered cone style muffler with a Supertrapp tip to top it off. The only other engine things I changed were removal of the secondary shafts (PO had removed the butterflys) and changed spark plugs but the old ones didn't look bad. Oh, and I removed almost 50 lbs. Now you can smoothly lug her down to 2500 or so and It pulls past 8500 with nice power and no bad vibes. Totally transformed, just a dream to ride!

Reading through these tuning threads I find it amazing how individual these bikes are, some tunes work for some, some run completely different.

Before:


Current pic, checking the Camp Fire damage in Paradise, CA last week.


Mock-up of the raw pipe parts. We rolled the cone and the 5" section from 18ga sheet. It isn't totally finished yet, still massaging it. I might add an O2 bung and will ceramic coat it once I'm happy with it.

Thanks, i'm using your Zuber3 Map now and it seems less on/off (still a bit, but i think it's the big twin). However when i start the bike cold it has trouble idling. When i rev it for a few seconds it keeps running but revs up to 2500/3000 rpm idle. After a while it gets to the normal +/-1500. BUT somethimes after a while it starts doing this idle again, even if the bike is on temperature.
Know anything why it behaves this way?
I have also seen it with the stock map.

And just for my education, why are the O2 sensors off? I have mine still on the bike and i wonder why it's off in the software if you were going for mileage (as am i).

looks interesting, might want to pull the shock and check to make sure the tire doesn't hit the exhaust on full up travel.

Have you adjusted tps to .6v?

I have, since that one has been giving me big trouble a few months ago.

Rharr, thanks for the concern, I do appreciate you looking out for me there. I don't have a good photo showing the inside clearance but there is a ton, pretty confident I don't need to do a swing check. I had a muff on my 450 EXCR that didn't clear with a 150/70-17 supermoto setup so I was well aware of the issue.

Zuber, great info on the mixture differences with the 2-1 setup. I was thinking of adding an O2 bung on my 2-1 but now I'm thinking it would be better to just WBO2 each cylinder. More work, but I'm obsessive.

I'll post up here if/when I get to it, It's really running fantastic but I'm sure there's more to be had. My only rideability issue is after steady cruising for a while, a slow roll-on of the throttle will result in a slight initial hesitation. I try and repeat it but it rolls on perfect. It doesn't repeat this until steady cruising for a while again. I have to assume this is due to a bad transition out of closed-loop mode since I have O2 enabled. I know it's been touched on here, I'm hoping that fixing the tables so the O2 trim is small might lessen or eliminate the hesitation.

Ideally I'd like to keep the o2's enabled. I'm not sure the gas we get has consistent ethanol content and sometimes I manage to get some clear fuel from a station I found in Medford, OR.

With the O2 sensors ON, you may get a flat spot just off idle and another somewhere between 3000-4000. Best test is to turn them off and try it.

The wild idle is usually due to the TPS voltage at idle and hot. Easy enough to check with TuneECU.

If there is still no love, I have another map on there that's a little richer. Zuber1 I think...

I recently did a cansiterectomy on my 07 990. A few weeks ago, in a different thread, I asked if I could disable the FI error light in response to the canister stuff being gone, and was told by another inmate I could. As I dug through this thread, I see your post above Zuber which seems to be saying it cant be done. Am I reading this correctly? (prior mentions to EGS vs EPC has me confused) Is the only way to prevent the error light to put in the resistor on that connector for the canister valve?

Look for a check box called sas, uncheck it

SAS has a check box. Not what we are talking about here. Leave the EPC valve connected, or put a very small resistor on it. I remember it's a 2200 ohm, 1/4 watt, maybe $2 for 5ea.

I'm still running the Zuber map on mine with a 2-1 Remus, runs great so worth the loss in mpg. I've left the SAS on, I like the burble and pops, don't see any harm in it unless I'm overlooking something...

I have a 07 with two exhausts Roadsitalia, I carry the map akrapovic downloaded from the web of tuneecu, deactivated sas and 02.
After a failure of the tps at 50,000 kms I installed a new one and adjusted to 0.6v.

With this map I have a huge pothole at 4,000 rpm, and I would like to try the Zuber map

Can someone send me a link to download it?

page 11 - post 216 - zuber1, a little leaner than stock
page 12 - post ? - zuber3, more leaner

Awesome, didn't realise you'd created another version. Will flash this on to the bike and report back! Cheers for these, Zuber.

Thank you very much, I've been reading the forum for days and I have not been able to find the files. My English is level 0.
Thanks again

Love this thread, and its been a lot of reading including the Got Tunes thread with 220 pages. lol
I have a 2010 990R, and I just last month ordered the Rottweiler stuff. So what I have right now is the Rottweiler intake, SAS removed, Canister Removed, O2 sensor dongles (Plugs added to removed O2 sensors), 2 to 1 pipe with a open Akra slip on.

Now I have the tune off of the Rottweiler site and its drinks fuel like an old 5.0 Mustang with a V8. .......
Currently its working 8.6 litre per 100km and that wasn't giving it combo city/highway. I know offroad will hurt this figure more.
On Idle, it does smell rich.... I would love more fuel economy.
I had the Akra map on it before from the Tune Ecu from the KTM 990R Akra slip on muffler and it had descent mileage. Had run that tune for 2 years. Reserve would light up usually over 230km.

Suggestions?

My suggestion is to lose the Rot intake and go back to the stock airbox.

I feel I'm too deep down the rabbit hole on this one. If its just choking off the air, then a plastic shroud can be made to cover a majority of the filter to resemble a stock unit. The ease of filter changes and changing on the fly is to glorious to give up.
I'd give up a little power for fuel economy right now.
Always worth asking, Thanks
