I have heard more than one person say that the 250/310 seems to be too rich on the bottom, to the point of being able to smell raw gas in the exhaust. This would fit with having to set it leaner to make it run right.
I'd love to tell you but I can't get mine to run half decent with any configuration. I had to set the accel pump to 5/1 to and the green to 2. I run mine with the same setup as you.
Not sure if you have any issues with your machine - But there is a lot of info on this forum in regards to upgrading the physical injector on the X-lite with a 12 hole unit. Better throttle response and performance etc. Acc pump to .5/1 no idea why it works, but it does. For me the richer setting wasnt the issue, it was only the acc. pump setting (I adjusted each setting independently in the attempt of creating a controlled experiment). I understand the acc. pump function doesnt actually control rich/lean settings directly, it more or less controls how early the richer/leaner setting is delivered in the rev range. Maybe it could be due to delivery of the increased fuel volume too early, effectively causing a over-rich condition. Sort of like prematurely throwing a huge log on a small fire.. sort of... Factory default settings that JD supplied me with were all two's for baseline/pass-through BTW.
Alright sounds good. I had pretty good crisp response except for the low end areas of course... I will try the suggested settings except accelerator pump down a couple notches. I will look into the 12 port injector. How much for the part? I will see how well the accelerator pump adjustment works. Thanks all for the input, lots of good information here!
These settings transformed my 250. Green/Blue (idle) 5 Green (low) 5 Yellow (mid) 5 Red (high) 4.5 Yellow/Blue (transition) 3 Red/Blue (accelerator pump) 1
I have a 09 smr450 It appears to run perfect. It has the factory power up kit with a single fmf powercore 4. Is there more power to be had with this JD tuner? I dont want to dump 200 bucks and not get any performance.
well i've tried on other forums , so why not here. i have a 2011 txc449, and after riding for about 30mins or so it starts bogging down and it will not run properly. it has about put me over the bars acouple of times, expecting a hit of power and getting none. i let it cool down for a while and ride it again and it repeats the same. it seems to me that there must be a heat sensor some where thats causing this problem. but i can not ride it like this , and that blows! help pointman449
Yes it does have a heat sensor and yes it sounds like you might need a new one. To save time I would call Hall's Cycles and talk to the parts guy. http://www.halls-cycles.com/
Thinking about buying one for my '10 TE 450. It has the p/u kit and runs well but seems a little lacking for power, especially on top. Does anyone have experience using this tuner on that bike? I read all the posts but didn't see one that addresses that model. I don't want to spend the money if the gains are marginal at best. Thanks
I have a 2010 TE310 close to these settings. Bike has a stumble at low end and if I set the RED/BLUE to 1 it runs good but not strong like at 5. However my milage went from low fuel light at 65 miles to out of gas at 30. I thought going down was leaning out, I'm I wrong?? Moved RED/BLUE back to 4/5 and milage was back up so the pump didn't move in the tank.
Higher number = richer. My bike wouldn't run at AP=1. I've given up on the stumble, unfortunately, and have learned to ride with it. These are the settings on my TXC 250... Green/Blue (idle) 5 Green (low) 5 Yellow (mid) 5 Red (high) 4.5 Yellow/Blue (transition) 3 Red/Blue (accelerator pump) 5.5
My uncorked SMS630 had a wicked stumble stock. I thought it was lean (since it was lean everywhere) but with the JD leaning it out more in the R/B and G/B made is super smooth down low. Of course above that I had to pour in the fuel to make some decent power. Cam.
2008 TE510, Been testing the JD tuner and found this to be good. Green (low) 5 Yellow (mid) 5 Red (high) 4.5 Yellow/Blue (transition) 3 Red/Blue (accelerator pump) 5.5 Except for the Accelerator pump, 5.5 was too much, after several runs, it came to run so much better at 3.4.. And I really think I will end up going downto 3. pretty much got rid of the low RPM stumble.
ok first you need to understand fuel injection and how the ecu works. suggest a degree in mechanical engineering and a masters specialising in fuel injection systems.!!! Seriously though firstly the jd tuner reads the signal to the injector, things like length of pulse, how many pulses per minute, . it then interprets these as to what it thinks the throttle is doing eg being whacked open quickly, turned slowly etc, what its position is, what rpm is. it has several adjustable parameters which the end user (me or you) can change. it describes these as if they were for a carbed bike, this helps us understand whats going on as i doubt anyone would make a lot of sence of a 3 dimensional ecu fueling map! green and blue lights are idle so how the carb would act on tickover green is 1/16-1/8 throttle etc etc (you have read the instructions!!). my particular bike (2011 te 310 with q4 silencer), had/has a stumble just off idle. when you turned the throttle a very small amount from closed it starts to stumble and hunt, the smallest turn of the trottle will then sort it out and it starts to rev and pull. (the problem here is in tricky stuff where your feeding in the throttle slowly and in small amounts) you dont want to be closed throttle but you dont want to be accelerating, also if you stand up riding over the bumps or whoops in this throttle range the action of being thrown back and forward makes you open and close the throttle a miniscule ammount making it very hard to control the revs or the bike for that matter. imagine your in a rut, u wanna use closed throttle but not lose speed but u dont want to get any faster. its bbbbrrrrmmmmm baaaaaa bbrrrrmmm baaaaaaaa brmm baa brmm baaa, like a see saw, if you have a 310 you know how much engine braking there is and how closed throttle forces u forward with this engine braking and how when they do start to pull the puuuuuuuuullllllllll. looking at jds maps and it shows that at 2200-2700 rpm(something like that) the fuel looks way too rich and the cures itself. i left the idle circuit (green/blue) standard as is mine is set to 90 on ibeat and im not paying £35 to husky just to put it to 100!!! However, the green setting i leaned right off so it would correct the standard ecus overfueling at this small throttle opening. you can see from jds lights that you go into the yellow range quite quicky from green and the actual green range is quite small. i set the yellow blue (transition timeing from green to yellow) to a lower than standard figure (think 2) this gets me into the yellow section of the tuner earlier so as not to stay in the lean portion any longer than is necessary. red i left standard at the mo and i have left the acc pump (red blue) standard mid setting. but from a starting point i would set this to 8 and eliminate it from the equation until you have all the other settings sorted. remember tune it like a carb (so that would be main jet 1st, then idle speed,pilot circuit and then needle taper) in that order. leaving the red (main jet) setting standard means that you should be pretty much ok as factory should be close to ok on w.o.t. so then sort the idle and get a nice clean smooth idle which returns quickly and smoothly, sloooowly open the throttle and see what positions change the lights. then you can work out what needs changing and works for you. having my bike ticking over on the stand and looking at the lights on the jd my stumble occured as it went between blue/green and green, so i knew fiddling with the green would make an improvement. if you wack the throttle wide open it isnt a smoothe rev up but has a momentary and i mean momentary hesitation if you do this more than a few times on the trot it will cough and stall with a bit of a pop/back fire. BUT its a 4 stroke not a 2 stroke, you should be squeezing the throttle the open the majority of the time not snapping it wide open from closed. 4 strokes dont like this, carbed or efi regardless. i think this issue on mine may not be helped by the fact that the tps needs resetting but at £35 a visit to husky it will have to wait,(unless they're reading this and gonna let me get it done for free, next time i go in there to spend my hard earned cash on parts and spares.) i have the throttle butterfly set open a little bit so as to minimise the engine braking, im going to set it back to roughly its position when i last had the tps reset and see if this makes the hesitation better. mine is better but not perfect but i would rather ride it with it almost right than waste the rest of my life trying to get it 100% My thoughts are that the jd tuner isnt a piggy back ecu so doesnt know the tps, the air temp, the coolant temp, etc etc, it just adjusts what it sees a little. if you go for a richer accelerater pump setting you arnt changing the standard ecu acc/pump fueling as the ecu doest have an accelerator pump. the thing with the jd is its giving you a new option. an accelerator pump. the jd know/guesses throttle setting and when it sees youre going from idle to wot it chucks in some extra fuel for a bit. as the stumble occurs at low rpm and almost closed throttle it can only worsen the over richness if the acc pump function set too rich. hope this has shed some light. obviously your ecu should be set to 100 100 100 as the jd says it doesnt adjust the richness or leanness to any way harmful setting. if your ecu is set leaner (like mine you probably wouldny be wise to lean it off any further) especially if in the road cruising part if the throttle range. if anything this is one of the areas you want spot on or a little rich. of course every bikes different with different pipes, different air filters, different ambient temps, different cam timings(minute differences between standard cams and chains) different squish bands, compression ratios, valve clearances, different fuel, octane, fuel additives different altitudes, different humidity etc. so no two bikes will be the same what works for me wont work for you and viceversa.
Hi all, I'm new to cafe Husky! I have a 2010 TE 250 xlite and have had issues with it in the wet conditions popping and carrying on. Seems to run well when its dry conditions! I have been reading about the Jd efi jetting Kit and have been considering fitting one! My bike is stock with original Muffler it has been deristricted, do I need to upgrade the original fuel injector and ecu to new 12 hole injector and ecu? Or can the kit be fitted without upgrade from stock? Have read on threads regarding the problems in the wet could be water on spark plug lead where it is attached to the coil! will be investigating this
Welcome to Cafe Husky! The JD Jetting EFI tuner default settings are designed to work with the stock injector and ECU.
Thanks Andrew, have been reading some threads regarding using it with 10 & 12 port Kawa injector or going for 12 port with ecu from Husky but I have stock Muffler! Any suggestions? Cheers!
