MicroSquirt, as a replacement for those who fry their ecu's. A tuning solution as well. I'm tempted to buy one to play around with, I can use it on about anything. It will also solve the immobilizer issue.
Probably not, but if you're trying to resurrect a bike that doesn't have a functioning ECU then you'll have to make some changes. There are some pretty good looking after market digital dashboards that can be used.
There is a chance it could work, not sure at this time. I may study up on it as time rolls on. http://theksmith.com/technology/hack-vehicle-bus-cheap-easy-part-1/ http://theksmith.com/technology/hack-vehicle-bus-cheap-easy-part-2/ Part 2 gets a bit scarey
I figured more like $800 to $1,000 all said and done. I am still in the market for a crashed or broken bike to play with. I surely won't experiment with my bike
In the last week I run the bike in stock settings without the EJK fueler. In this period I haven't experienced any stumble at all. The only mods I've performed to the bike are the Unifilter and the Brisk spark plugs, and I think they played a factor in the behavior of the bike, although it seems that the more miles you put into it, the better the tr650 gets.
The MicroSquirt V3 is the one to use. It's a fully assembled ready to go and is tiny. It's about $340 or so. I've always wanted to try my hand at one. It's the real deal, complete programming from the bottom up. You can do it for fuel only or add in spark control if you want. I was thinking about this for my KLR, just fuel only as there's no crank position sensor. But the Husky has one plus the other sensors so it wouldn't be that hard.
I think that this would also power the dash. Might take an aux. daughter board, might not. This unit is compatible with the wide band O2, so precise tuning is possible. Adjustable and programable ignition, fuel and if very creative you could add a gear selector sensor and incorporate that as well. My reflashed Dobeck showed up, so that will get added next. Since my bike runs well, I'm not adding it to fix anything, but to see if I can get more ponies. I'll wire it in on a separate circuit that can be switched from stock to fueler.
Have installed the Innovate LC2, set the AFR to13.8:1 and she runs great. Not an overly hard installation but it is not a plug and play option either which might put some people off.
Heya Geeza, what other AFR's did you end up targeting or are you going to bother? The LC2 makes a huge difference doesn't it?
Ran 14.7:1 first up, small difference, suspect the bike was running leaner than 14.7:1 from factory. Next ran 14.1:1 - noticeable change but not perfect, then on the advice from Roger went straight to 13.8:1 - this seams to be the sweet spot for the bike. Have just returned from a 435 kilometre trip and it just keeps getting better as the ecu relearns the fuel trims. The ride was all tartop, mix of highway and small twisty roads - returned 38.33k/litre or 61.41mpg(US). Feels like I am riding another bike, idle is rock solid, no hesitation and smooth linear acceleration - torque - sh*t loads more and down low so the bike can be riden like it was designed to be, roll on the throttle and let the thumper torque do the work. Gear changes are smoother and low speed riding is easier as the engine does not feel like it is going to have a dummy spit. Big thanks to Charlie and Roger for all the work they have done and the help provided. This has to be the best money I have spent on the bike and I like that I can connect a computer and watch/ record what the AFR is doing, not guess which I belive you are doing with some other devices.
Geeza, Glad to help. You've taken some good data too, which helps everyone. As you have time it would be great if you logged some longer runs so we could see just what the MM ECU does with fueling. The other important thing is that your observations on the bike are the same as for those who add an AF-XIED or other lambda-shifter. You make a controlled richening of the mixture, anywhere between 4% and 6-8% (one of my friends is at 10%). With an LC-2 you get cataloging but a greater install complexity. With an AF-XIED, no logging, but plug 'n play.
Inteneded to log yesterdays ride but ran out of room for the laptop once I had my gear packed for the day :-( Will get some data for a longer run soon and get it to you.
Hey guys. I'm using a wb02 wideband controller. this controller is very configurable with a narrowband simulation. however, i'm getting a massive flat spot on steady cruise. just slowly dies and gets slower if i leave the throttle static, ,if i then slowly open the throttle it really dies, then it hammers. it's great is you are just accelerating and decelerating. like on a race track i'm using an afr 13.8 as the cross over point. i don't have an AFR display yet so i'm flying blind. and the logging function on it doesn't seem to work Does anyone know if the tr650 uses anything like the bosch lsm-11 voltages.? What voltages are people using with the LC-2 narrow band simulation.. I'm varying between .2 and .7 volts either side of my selected AFR. Does anyone know what voltages the ECU is expecting? It's the strada with pod mod, std exhaust no cats, std IAT sensor, air temp today around 100F (40C)
Hi, running the LC2 at 13.8:1. Not sure these voltages will help but have 0.8volts at 0.935 lambda and 0.099 volts at 0.945 lambda. I think the LC2 uses the Bosch LSU4.2 sensor. Hope this helps.
