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

reply fail.

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.

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!

Thanks alot now it works, will be back with my settings when im done tuning.

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.

db511 I run the same system Pro Circuit T4 Full system on a 2012 TE449 and same issue popping and flame on down shift or backing of the throttle, Just waitning on my JD tuner to come. It luck with setting's.
