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 The previous version was outdated and no longer supported.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

Installing TXC ECU on a 2012 TE310

Can anybody with experience doing this job provide any detail on how its done? Do you have to remove the tank, if so, what is the best way to do that? Also, do you still need to install a resistor in place of the lambda sensor, or does that wiring all go away when you take off the TE ECU? Does the TXC ECU still use the blue mode switch on the handlebars? Sorry for all the questions, but inquiring minds want to know. Thanks in advance for any assistance.

Hi Mike,
You do have to remove the tank, I don't completely unbolt the shrouds just where they connect to the front of the bike and the bottom bolt, then I just move the shrouds out a bit, and lift the tank slightly at the rear, just enough so I can get to the QD fuel connector. From there I depress the two buttons on the QD, sometimes I have to use a screwdriver to depress one side, and gently remove it off of the tank, there is also and electrical connection right by the QD you have to unclip. There is one more electrical connector under the right side of the tank, it usually has a zip tie on it to keep it connected, remove the zip tie and unclip it as well. From there you should be able to remove the tank. The ECU is right under the tank and it is easily removed, as is the fuel injector it is held on by two philips head screws, they are a real PIA to get loose they are supposedly some Japanese standard heads?, I used set of vice grips to get mine off, then I replaced the two philips head screws with some stainless allen head screws from the local hardware store. I think that is about it, nothing really to it, and the bike runs so much better with it installed. I left my resistor in the lambda sensor, and my blue mode switch still works great. I forgot to mention there is a cross over fuel line from the right and left fuel petcocks that needs to be removed I removed mine from the left side, and replaced the crimp style hose clamp with a fuel injector style hose clamp from Napa, although I think a standard one might work fine at that junction as well. I removed the throttle body to get those PIA screws loose, and I think that was the proper way to do it, otherwise I am not sure you would ever get them loose. Its no different than remove a carb from any other bike, the throttle cables hook up the same way.

Thank you very much for the information. Did you have to reset anything in iBeat when you were done?

I wish my dealer knew how to use the I-BEAT at the time but he didn't, and I have never spent the money for it. With that said I didnt do anything but plug and play and the bike runs flawlessly. No fueling issues at all. I probably just got lucky on that one!
 
Parts on order. I'm thinking I'd better change out the plastic quick connect on the tank with one of the metal ones. Anybody have any recommendations for a source and install instructions/advice? Thanks.
 
Does anyone know the screw size for the injector hold down screws? I would like to replace them with torx or hex while I am swapping out the injectors. Thanks.
