Sorry I don't have the new ECU like you do but just wanted to say the air bypass screw is not for adjusting the idle speed but for adjusting the mixture ratio during idle. I too faught high idle for a while. I ended up slowly working my hard stop to slow the idle while making slight adjustments to my JD tuner to keep the low end in check, and keeping the TPS calibrated with iBeat. The CO by itself really won't do anything to idle speed either. I idle around 2000, have a good low end and a great plug color. Hope this helps.
Does anybody know what the factory settings are for the throttle hard stop and air screw are for a 2010 TXC 250? I'm trying to find a baseline to start from.
Hi Jimbee, I'm certainly no expert in this field, but here's something I did that maybe you didn't. Before doing anything else, I adjusted the butterfly stop (the allen screw and nut combo) to "fully closed", meaning the set screw had no effect on the butterfly plate at all. Then as I twisted the throttle, I noticed a slight "sticking" as the butterfly plate released itself from the throttle body. So I adjusted the throttle stop until the plate was as "closed" as possible without sticking. Then, with iBeat (thanks again, Doug!), set closed at "0" and WOT at "100", and all CO at "100".
I thought that you can only reset the TPS at 0% and that you then have to live with whatever WOT% you get. I've only been in iBeat twice, and perhaps it was the older version of iBeat. Is there a way to set the WOT position to 100% on the TPS seperate from setting the closed throttle position?
You may be right, my memory is terrible. I wanted to emphasize that I nearly closed the butterfly with the stop before I set the TPS. I'm pretty sure it was close to 100% at WOT, though.
Since Huskys FI came out in 2008 I haven't ever seen a baseline to set the hard stop at least coming down from the factory. I think their is no baseline but to set the hard stop to a position where the bike idles approximately where the manual states, then to calibrate it with iBeat so the ECU knows where it's at. The air bypass should get treated like an airscrew on a carb, tweaked until you are able to get a clean throttle snap. That's how I do it and actually find theirs a small difference between how I adjust the airscrew early on with a warm engine vs later on In a ride/race with a blazing hot engine. All just IMO though...
good info Jason- I think the xlite's, as you have found, need a higher tps WOT than the legacy bikes. I have found good results on legacy bikes 450/510s 08, 09, and 2010s with a WOT of 100.2. My buddy's 11TE310 is running pretty amazingly compared to reports here- stock ECU (but I am not trying to sway anyone's thoughts about upgrades to the ECU/Injector). Maybe its a combination of the TPS setting and the CO's. We've been thoroughly impressed with this bike. The bike was set up by the dealer on Ibeat with Power up. It ran real great- but we have just been playing with CO1 and CO2 settings to perfection as there's no big issues only minute adjustments. I'll try to get the TPS readings on that and share them. If I recall they are higher than previously recommended for the "Legacy" 250/310/450/510 if i recall it was like 101.something.... Here's some good reading that may assist those new to Ibeat/tps: http://www.cafehusky.com/threads/my-diy-efi-tweak.3885/page-4 http://www.cafehusky.com/threads/ibeat-semco-efi-info.6079/page-6#post-200441
My buddies 11 TE310 with sparky out, JD tuner and otherwise completely stock runs great. Playing with the "accelerator pump" setting on the JD took care of 95% of any hesitation on the bottom. I have ridden it for many miles, no issues i would be looking to buy more stuff to solve. Look forward to riding a 12 port bike and seeing whats up. Still REALLY want to try a 2012 TC250.
Start-up and off-idle response 2011 TE310 w/TXC ECU+12 port, stock Arrow and sparky. Clean and smooth . Love that exhaust bark. My buddy's KTM 530 sounds like an agricultural machine of some sort by comparison.
Hi all, I've just ordered the ecu/injector upgrade kit for my 10' TE250. I'm still running the stock exhaust but hoping that this will help out with the bottom end bog. Just wondering how it will be affected if i don't get the TPS reset as i don't have an Ibeat or if there is any other way around it?
I just did my ecu to the txc one. My new ecu was set at 1000 and my sensor read 940 so it is a good idea to get it set
I have never moved my tps sensor and that is what I ended up with for wide open throttle when I calibrated the new ecu
Mine is on its way Figured it'd come in handy in the future. Just need to read up on how to use it now.......
