Ok guys I need some background. My 03 Vee sidecar rig does not have any aftermarket tuning equipment on it, but I could have been teka or yosh tuned. I don't have any off idle problems or noticeable surging. It does have the rough under throttle under 4K that is worst from 2700-3200.

I'm contemplating getting a PCFC to smooth out the bottom end.

Anyone know of a way to find out if any previous ecu tuning has been done?

Is it worth doing a custom tune vs trying various downloadable added maps?

A dyno run would be a bitch as I'd have to divorce the hack and trailer the bike somewhere for a dyno
run.

Thanks.

i just installed the pcfc on my 05 dl1000 it had only a k&n air filter added. but had rough lean spot there around the rpm you mentioned. with the tune included on the pcfc i selected the 2nd option and most of the stumble is gone. i am however going to try a couple of other tunes listed on here and see if it goes away completely. i also had the same suspicion about mine being tuned some but had no way to confirm. this pcfc seems to have overridden the fuel maps and used its own. So far so good.

I don't know of any stroms that have a ECU that can be tuned, the only way is to add aftermarket stuff.

Incorrect....a TEKA or Yosh box can actually re-flash the ECM at certain RPM's and %.:smile2:

Just thought I'd follow up again for the permanent record:

Bib B's V2 map so far is the BEST map for my setup. 2005 DL1000, Two Bros, stock filter. I like this map much better than the Dyna Jet suggested map. Finally got the luggage unloaded and got to take it for a good run. Still some subtle pop if engine braking, but performs better than I originally though. Thanks, guys!


P.S. I've also got a ripper of a map done by Jet Tuning in Camarillo for this setup; it's no good for fuel economy and it boggs down low, but it unleashes the beast in 5k+ territory! If anyone wants it, let me know.
That is great to hear, my 05 ran like a raped ape and still got good gas mileage with that map, I spent a lot of time tweaking it. :smile2:

Did you have any decel pop? I thought I had exhaust leaks eliminated, but I noticed the other day there is a small one where the CA legal 2Bros slip-on connects on the right side. Haven't checked intake leaks, but I guess I better. Also wondered if a K&N would help more of the fuel get burned in the cylinder (but I know many say the decel pop is actually due to a LEAN condition). It's just a little annoying, and hard to forget about. :)

A little bit of deceleration pop is fine, you don't want the kind that blows off throttle body boots though.

I'm still running the big b map on my 06. It's a good all-around map.

Wonder if even need a tune

I am fairly new to the V Strom world. Purchased a 2003 DL1000 in Feb 2018 with 49K miles.

I have done a TB sync and checked the TPS calibration, all is good now. The bike has a pair of Remus Slip-ons and a K&N drop in filter. By all accounts it should be running pretty lean, but I am not detecting any signs of a lean running condition.

I suppose a previous unknown owner had the bike tuned with Yosh box, is there anyway to tell.

Hate to spend the $ on Power Commander if it's not needed.

Brian I have the same question about my 2003 DL1000. Does yours have aftermarket mufflers and air cleaner element? Have you synced your throttle bodies, I just did and took the majority of the roughness between 3000-4000 RPM.

I like you wonder if someone has reflashed the ECU can't find a way to prove that one way or another.

Hope someone can shed some light on our questions.

Playing around and unhooked the PCIII on my K5 and took a ride. It was terrible. Lean, popping, wouldn't hardly idle. Hated it. Hooked the PCIII back up and it became an enjoyable bike again.

Wow, what a huge difference. Now I remember why I bought it 10 years ago.

Cause of your rough running not Fuel Injection

Ok guys I need some background. My 03 Vee sidecar rig does not have any aftermarket tuning equipment on it, but I could have been teka or yosh tuned. I don't have any off idle problems or noticeable surging. It does have the rough under throttle under 4K that is worst from 2700-3200.
I just re-read your comments and since my first response to you a few months ago. I have since found and cured the cause of the excessive vibration you are feeling between 2700-3200 RPM. It is the clutch basket (chudder). You will need to replace it with a modified unit to remove those vibrations. Of course poorly sync'd throttle bodies can add to this issue as well.

The problem is Suzuki's poor design causing too much movement amongst all the parts that make up the basket assembly. As the miles add up these tolerances get bigger to the point of causing the issue you and I have experienced. This is a well know issue with the V Stroms' and Suzuki has never really addressed the problem.

The solution is to get in touch with Werks Parts, LLC and either make arrangements to have your baskets modified to fix the issue or buy and exchange unit. Terry the owner is on this forum often and I can tell you from my personal experience his work is a sight to behold, besides it works miracles to smooth out the Big Twin.

Terry also has a Youtube video showing step-by-step how to change out the clutch basket, if you have GOOD mechanical skills you should be able to do the job yourself as I did.

Here is the link to Werks Parts, LLC: https://www.werksparts.com/

Give Terry a call he will be happy to walk you through what he has done to fit Suzuki's piss poor design.

Good luck.

Map testing, ongoing results
I'm going to be testing several maps; we'll see how they stack up!

My bike:
07 DL1000 motor (in my 04 chassis)
K&N Air Filter
Two-Brothers Cans
Secondaries removed
PAIR plugged off

Baseline map:
m311-K4_SBK_BigB_v2, no accel pump. Results: first time I've been able to wheelie my 1000; responds great at all rpms and throttle positions. 32mpg.
(Why this? Because...that's what was installed before I decided to try other maps! And because I didn't have any idea about the accel pump feature.)

Tested:
OMG custom map. Results: Compared to the BigB_v2 map, the bike ran pretty poorly, was low on power, and mpg didn't improve any.

m311-K4_SBK_BigB_v2 with accel pump enabled and set to the settings in the map notes. Results: back to good power, running cleanly, seemed a tiny bit less powerful above 7k rpm than without the accel pump. After ripping it up with @Karlos at 6k rpm and higher for a few miles, then a slow and super rocky two track for a few miles, and some hiway miles, got 33mpg.

04-07-20 - Cheff's power and economy; accel pump still enabled. Results: 30 mile ride, hesitation and sputtering in all gears at any rpm if the throttle is below about 10%. Above 10% throttle things seem smooth and there's decent power. 101 miles, a little over 37mpg.

04-08-20 - CriscoKid 07-18-07; accel pump still enabled. Results: I like this map a lot! After several hundred miles and many tanks of gas, this map makes nice and smooth power in all gears at any rpm while the throttle is above about 10%. Takes just a little more effort to wheelie than with the BigB map. Below about 10% throttle (like in 3rd gear going slowly on dirt roads) the throttle is pretty snatchy. Mostly when rolling off the throttle. I'm getting about 36MPG when flogging the bike mercilessly; and I got 38MPG while riding conservatively. I'm very, very happy with this map!

Tesing:
05-20-20 - WildDoktor-CriscoKid 07-18-07; accel pump still enabled. I was told that enriching the map a bit at those low throttle settings and rpms would fix the "snatchy" issue, so I've done it: I've tweaked this wonderful map a bit down low and will see if I can smooth it out down there, yet retain the high MPG and other qualities of this map. Will begin testing tomorrow!

Next maps:
CriscoKid 07-09-07, 07-18-07, and "summer"
Cheff's power only
Jett Smooth 05

My 05 ran amazing with the 2 maps I made, gas mileage was typically in the 40's as well......glad to hear there are still some benefiting from them. :)

My K5 has run well, much smoother than without a PC, using a slightly richer map than the default PC map. MPG is still mid-40s, at 41K miles. I installed the PC within a few weeks of purchasing this K5, new. Other than the PC, this bike is stock.

Question: how do you know (seat of the pants) if a section of the map is too rich or too lean?

Use your nose for too rich.

I'm going to tell you my experience with BigB map and Exlaper K5 Jett map. I was using BigB map for a year the bike runs great, but when I rev the bike I would smell gas (stock air filter). Last week I installed Exleper Jett map. When I look at the map numbers it looks just a little bit leaner, I lost that gas smell when I rev it and I think that is good throttle response like with BigB map. I checked it on back roads and I got 39.5 mpg which is good enough for me. I might install BigB map again just to checked mpg I would be surprised if I get better mpg.
I have K7 with Termignoni exhaust and stock air filter.
