  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

449/511 JD X6 EFI tuner in the house...

WOW. full report comeing, was not expecting this.

I just posted this on Kreigs 449 pipe thread to give you an idea.

FYI though I am working with JD on some settings as the programmer is out of range on some stuff and need tweaked for this bike.

But as is...

Guys, i have a pipe on my TE511 and it was running perfect after the idle screw tweak, or so i thought. Last night i added a JD X6 Tuner to sort the wiring and base map for JD. I was installing it thinking why? Had to keep telling myself it was for my customers as i sure don't need it. At first it did not feel like it did a ton but ran better right away. Just smoother and perfecter. :D More perfect? Anyway, I mounted it to my handlbars and was jetting at stop lights and while riding!!! I ended up richer on everything and WAY richer on the top setting as it feels flat up there. Result? You know how much power that pipe you just installed added? This adds that much more. No shit. And it runs better over all. The roll on power is nothing sort of stunning. 55 mph wheelies are right there. lighting up the back tire at will in any gear on gravel. Instant throttle response and impossible to stall. I have never ridden a better running bike. the down side is that it went from a docile kitten of a EZ to ride bike to a fire breathing KX450 type gig. I like it but some people who want a tame trail bike (like it is stock) might not. Absolutely RIPS and runs perfect. No popping ever. No EFI glitch AT ALL. Perfecter.

cIf you have or could take a picture of the JD tuner wire connected to the proper wires on the throttle body, i have a 449 and a tuner not yet connected. The picture in the instructions is not very accurate. I would appreciate it.

Hi
I just bought a JD Jetting tuner for my husqvarna 511 smr -12.
But I have some problems with the installation, the big contact for the injector fits but I cant find any where the 2 pin smaller one could fit.
Where should it be connected ?

Not sure about 511, but would think its the same. I just did mine last week and two plugs. one into the throttle body and the other connects to what you just unplugged.
 
Unplug the injector wire right above the sub tank, plug int he EFI tuner and plug the factory injector wire into the EFI tuner female socket. Does that answer your question?

So what did you end up putting your JD settings at? I have an SM511 here in Portland with slip on pipe and JD jet kit. Just no dyno to program it perfectly...

Any help would be appriciated!

Most of them need to be richer in the yellow and some int he red. Yellow seems to have a lot of affect on power. Also play with the idle and acceleration pump functions, there is better running and power to be had there too. My bike was used on JD's dyno to make the original map. The flat settings should be close and then you can tweak it by seat of the pants feel from there. Hope this helps. BTW all the husky JD ran across his dyno / sniffer have been lean even in power up mode and especially on top.
 
Now im done tuning my 511 smr -12 .

I have installed a JD Tuner, innovate mtx-l wideband sensor and modified the stock silencer to free flow 38mm with no cat.
It also has racemap 2.
I havent dyno it but its big differens between stock and with these mods!

My jd settings are:
Green 2 = AFR 14.2
Yellow 4/5 = AFR 13.0
Red 2/3 = AFR 12.8
Greenblue: 4
Yellowblue: 4
Redblue: 3/4

This is on swedish 95 octane.

Here some pictures:

Nice, thanks for posting your settings. I wouldn't mind hearing from everyone who has the JD Tuner on what their setting
are and what's working best. I fiddle with mine just about every ride but haven't actually gone from one extreme to the other
in a full blown test. Too busy enjoying the bike but someday I will set aside some time to really try and get it dialed in perfect.
 
well i just installed two tuners today, on two 2011 txc 449's.
lets just say the instructions leave alittle to be desired?
don't bother taking off the right shroud, it's the left side that needs to be removed, then loosen the fuel line and theres the connector, remove it add jd tuner , put back on the fuel line run wires and , done!
ihaven't rode it yet but tomarrow i will for sure, then report back.
 
Only a few people have posted up their JD Tuner settings so far. Does anyone else have one of these installed that would like to share their preferred settings? I have a 2012 TE449 with the FMF powercore4 pipe on it and I think it could really use some re-fueling. There is a strange surge at mid rpm and it falls pretty flat at high rpm. If anyone has the same set up as me and has found thier perfect settings I would love to hear them.
 
I have installed a Pro Circuit T4 full system on my 2011 TXC 511. I had the JD already and have everything richened quite a bit. This bike screams now, only "issue" is the popping when engine breaking on downshifts. Never when accelerating though. Definitely worth the money:-) I will check my settings and post them as soon as I am home.
 
I have a 13 TE511 with fmf slip on. In race map 2. With the tuner in factory settings it is runs rough at cruise. Example 4th gear at 30-32mph it feels like it's running out of fuel, like the throttle is jumping. I set all the settings back to 2 and it went away. It felt flat though on rapid acceleration and up top. Where should I start on my settings to get it dialed in. I want the power but also want the cruising rim range to be smooth.

The mid range is overly rich so that makes sense. Try these:

green blue - 3.5 or 4
green - 3.5 or 4
yellow blue - 2
yellow - 2
red - 3 or 3.5
red blue 4-6
 
Will this tuner allow for startup mixture tuning? I believe I am overly rich during start up. Will this tuner allow the stock programmed ECU to be recalibrated acceptably. I currently have race map 3, but this ecu has a problem where it will not shut the engine off. I have a new standard program ecu, and would prefer to have the tunability over race map 3. Send ecu out for race map 3, or buy tuner and use standard ecu? Like idea of being able to tune a cold start issue I am having, but don't want to spend money on map 3 and the tuner. I have an fmf pipe and the butterfly is removed.
