• 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 The previous version was outdated and no longer supported.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!

Need opinion on JD tuner

#3 settings don't really "work" for all those bikes, it's just passing the signal thru unmodified. It's on the purchaser to figure out what the bike needs.


.
 
The stock #3 setting isn't changing anything so whatever the stock ECU is sending to the injector is unchanged. So the stock setting on the 610 ECU goes straight to the injector and the stock setting 510 ECU goes straight to the injector and so on for the other models.
 
Thanks for all the replies. I'm gathering that the tuner just comes set at #3. Does JD provide you with recommended setting changes for your bike (based on his testing) or are you totally on your own?

Some guys have claimed improvement by just plugging it in, so I assumed it had to come with optimized settings programmed into the thing for your bike. That was causing my confusion.
 
Any change caused by just plugging in the JD with the factory settings is due to the transition ranges and the acceleration enrichment (the last three settings) and will be pretty minimal compared to what you CAN get out of it by trial and error and your butt dyno, or a real dyno if you have access. There are several threads with people's JD settings and mod lists, so that would be a good place to start.

I just got mine about a week ago and specified that it was for a 08 610sm, it came with settings already setup that were almost the same as I'd found in a recommended settings for the 610 thread here on CH. I believe JDJ put's their settings in ahead of time for your specific bike ( if you have the same mods that they dyno tested with ). If I'm incorrect I'm sure somebody will speak up, regardless it will be obvious when you try to put settings in to the programmer, when you advance up, non stock settings ( not a "3" light ) will be there.
I must admit it works pretty damn good right out of the box with the settings that were included with mine. It's worth every penny.

I called Dave today and he explained to latecomer to the game me (probably what most of you already know) that the tuner does come with pre-programmed settings for the model bike. It just so happens that Husky has the ECUs programmed a bit lean (as others have already said) for the 540,510, 610 etc. and the settings seem to work pretty well across the board for all of them. So one model covers several bikes, which I couldn't wrap my head around. He also mentioned that they can change the percentage of fuel compensation between steps if one ever wanted it. The 3% change for 1/2 steps can be adjusted. I doubt I'd ever need it, but some with big mods have had it changed and love it. He also mentioned the 30-day money back policy, but I'll take me more than that to fiddle with it. :D

Sorry to re-hash all this for those who know all this already.
 
Biggest thing I noticed after fitting with the stock settings is when cold the bikes fires up at the touch of the starter button and idles without need for the coldstart lever. Before the JD my bike would not start and idle without the coldstart level until warmed up. Power across the board stronger and throttle response snappier. I had the PU and a pipe before fitting the JD.

At one stage when playing with the tuner I went too far and too rich which made the bike hard to start hot or cold. Dialled the setting back problem solved.

Are you sure this is possible? The tuner takes 5 sec before it takes over, this I was told by JD. The 1st 5 sec are the ECU alone.
 
Mate, I'm no tech guru all I can tell you is what it has done too my bike. Starts and idles from cold at 1600 - 1700rpm without coldstart. Would not run when cold before without coldstart lever being pulled.

If the 5 second startup begins when you turn on the key then pausing for the dash to start up before starting could account for it. If southy is still running a stock dash and waits for the dash to completely start up before trying to start he'd be using up most of the 5 seconds. This is assuming his 09 has the same dash as the 08.
 
Southy, I'm not discounting what you're saying is true, I was just wondering how it could be. I thought the the bike had to be running for 5 sec before the tuner kicked in. I must have misunderstood JD when he was explaining the details of his wonderful little device. I had hard starting myself and asked if I add more fuel at idle will it help with starting (higher rpm) and was told " no it won't raise the RPM's " and that the bike starts with the stock ECU settings. I never tried to see if it helped, I just did the valves and that did the trick. I never discount anything anyone has to say on here, I was really just asking a question and I didn't mean to come off the wrong way.
 
1lunger is correct...I have personally spoke with James Dean on several different occasions and confirm what he said. The fuel tuner does nothing for the first 5 seconds once your bike has started. However, you can send your tuner back to JD Jetting and he can modify the tuner to come "on line" sooner or later.

I am not sure about JD's other fuel tuners, only the units designed for Husky TE610's and 630's.
