Can anyone help me out with a telephone number for Techlusion please?

For some reason their website doesn't seem to be working.

I just talked with a tech at Dobeck asking him the difference between the new 1045st and the 1040 box I have on my XB now. He confirmed a couple of things for me. The new box integrates with the O2 sensor and allows adjustment in the closed loop range of the map without fighting against the ecu. He confirmed what I expected my 1040 box was doing. The ecu was basically readjusting itself in the idle/cruise range and negating the adjustment I made on the techlusion green pot. He said what happens is eventually as the ecu adjusts, you run out of adjustment range on the 1040 green pot. He also confirmed that the new 1045st was set up for different injector pulse widths than the 1040 box. In addition, I asked him directly if the new 1045st box would make the check engine light turn on. He confirmed that it would not set the light on.

I'm still unclear if you can use this box with the Race ECM or not. On the site it looked like they were saying it was only designed to be used with the Stock ECM. Anyone? Anyone? Bueller?

Just a note to let you know that once you dial in a DFO on a Dyno you should check it periodically. My initial set up was done almost 3 years and 10.0K miles ago and I had a full dyno tune done today. Due to what is considered normal engine wear, it was running a little lean on the bottom and fat on the top. Minor adjustment and everything is perfect!

Well my TFI arrived today and after getting the injectors connected and routing the harness from the battery box on the xbr, I ran into exactly the same problem as DCMortalCoil. Hope I get to ride this weekend.

DC, do you have a part number for the connectors you bought and are they weather-proof? I don't want to remove the TFI now that all the wires are routed, so I can't simply match up the connectors without taking something off the bike : ( This sucks! Missing bike night out here as well. Also how do you know which connnectors go to the front vs rear injectors? I put yellow to the front and green to the rear ( I am talking about the TFI wire colors).

I may just redo and solder them, but I hate to do that on a new part under warranty.

Hint not in the instructions. Don't disconnect the fuel rail as per the instructions, simply remove the right air scoop and you can easily get at the injector connectors from below the frame rail.

After checking again, at least they put the right connector on the tan wire. Now all I have to do is get the pin release tool for GM Weather Pack connectors and swap the connector bodies. Or maybe a pin puller for RS-232 connectors on computers will work. Guess I'll stop by the office and pick the tool up (computer).

DC-thanks for all the info. It does look like I'll be able to ride after all. BTW, did you have to splice the wires, or did you just have the wrong sex connector body on the wires, but the proper connector pin sex?

Lastly, I hope we are positive that the brown wire goes to the 02 sensor!

Thanks,

Xbolt12,

I got the final confirmation (Sam take a note) from George of Techlusion - the pink/yellow wire is the one that connects to the O2 sensor and the tan wire goes to the XB harness.

Bottom line, the pink/yellow lead needs a male connector (smaller one) with a female pin. The tan lead needs a female connector with a male pin.

I got the HANDY PACK part nos. ET743 & ET744 (plastic connectors) and ET735 abd ET736 (metal pins). Pretty cheap.

This all sounds good, especially that the new TFI appears to have the ability to fool the ecm into thinking the air/fuel ratio is fine (if what the tech speaking to Captain said is correct). This could be a lot of fun. I would think it would work equally well on either race or stock ecm. Here's hoping for some great results.

That is correct concerning the old style Techlusion DFO's, should be true with the new style unless Techlusion says different.

The combo I put together for my X1 caused surging with the Stock ECM. Have not heard of others (either Buell or Harley) with the problem, so I consider it a freak experience.

Note the addition of the Race ECM was the cure. May not apply to XB's at all. YMMV

Hogs...I know this is nit picking semantics, but did he say "Don't" or "Can't?

To me, that implies either you "don't" need to use the Race ECM or you "can't" because it won't work with the Race ECM.

Trust me, there are days I hate this language. Seems you always have to play "20 Questions" to get an accurate/useable answer to your question.

Just wondering. Am sure someone will post a subsequent conversation or experience with Techlusion.

Hogs...Not trying to be smart with you. Was just interested for future reference should I ever pick up an XB.

I have an X1 with Race ECM and Techlusion DFO that works extremely well and won't be in the market for another Buell for quite some time.

I never gave it a thought that Buell messed up with the Race ECM. That in itself is an interesting tidbit of information at least in reference to the use of the new Techlusion unit.

Thanks, and try and to have a good day!

Got the connectors. I'll post the Belden/NAPA part numbers tonight when I get a chance (for anyone else who gets a TFI with the wrong sex connectors for the oxygen sensor). Napa also carries the tool for removing the connector pins.

I let you guys know how it goes tonight. Last night was spent getting the pins out of the connector with the w/o the tool. I used a butt-splice connector with the plastic removed and the stop reamed out to remove the pins last night, but then found out it wasn't the brown wire that should go to the 02 sensor after all (I had simply swap the connector bodies, not the pins).

DC, thanks for the info (even though I didn't read it until after my troubles). I'll let you know about the LED patterns.

Wahhh Hoooooh!

Thank you Dobeck Performance!

For those of you who wonder about the TFI, it works so well I can't believe it's the same bike. Ping is gone completely. I just got back from a night ride on a nearby twisty road and I can't believe the difference. I can't get the bike to ping even if I go up two gears and roll on the throttle below 2k!

I haven't even tried any setting other than suggested, but basically the bike runs better, smoother, and seems to have gained some hp on top. I suspect the bike has gone from lean in the middle to maybe a little fat now (no biggie-plenty of room for adjustment either way). I think a dyno tune would definitely add some hp to parts of the power curve now that the mixture is tuneable.

For those who don't already know, I have an xb12r with race filter, snorkel removed except for just the top inch or so (used to seal the airbox base, stock ECM, and stock exhaust with servo. Since I removed the snorkel (most of it), I have had a significant increase in pinging when rolling on the throttle at around 3-3.5 k. It's all gone now! Makes me wonder how lean it really was. Also the fan isn't running as long in high speed mode after a hard ride.

I can't wait to see what it will do with a Jardine!

Also while I had the airbox base off I put heat shield material on the bottom. I also did the same to the seat (tired of chessnuts roasting on an open fire).

Tomorrow I will post the connector part numbers for anyone who got a TFI with the wrong connectors.

I swear with every mod I've made the xb just seems to get better and better!

With the steering damper, Diablo Corsas and TFI, now it's becoming clear that I need to stiffen up the suspension (and maybe some suspension work if I can ever save some money up).

Sure wonder what those magazines would say if they tested an xb12r with the changes I've made. I'll bet they would be supprised!

Dcmortalcoil,

The LED's seem to behave as you describe, although I have not checked them since I've ridden the bike.

Frankly, the bike runs so well now that I'm not worried anymore.

Part numbers (NAPA Auto Parts) for the replacement connectors on the TFI unit:

784513 male terminal (5)
784513 female terminal (5)

725153 extractor tool

If you need the connector bodies or for other projects:

784520 single male housing w/seal

784519 single female housing

784517 Silicone cable seal (5)

If you need to cap a disconnected plug:

784518 Silicone cavity plug

These are really good connectors (wish I had know about them before) and would be useful for other wiring projects. I used a standard automotive crimper and followed up with solder, just like the original connections on the TFI (the proper crimper is expensive).

For the TFI fix (if you had the mis-fortune of getting one with the wrong connectors) you only need the top two items (possibly the extractor also, although you can use a thin sleeve pushed down over the outside of the pin to release it-I used a modified butt-splice connector, but the extractor is much less hassle). Dobeck will ship you the replacement connectors, I simply did not want to wait and I wanted extra connectors for other projects.

Sammigs,

Yes they were flashing or cycling would be more accurate. I have not checked them since riding the bike.

Took the bike out today for a hard ride (Palomar mountain, etc). It was late afternoon, but still pretty hot out. The bike will still occasionally ping on hard acceleration at low rpm exiting turns. Not much mind you, just a little rattle now and then-nothing like before.

I did have something weird happen in a long parking lot tonight though. Not sure if it was me and I almost stalled the bike or if it was a brief fuel issue. I was crossing a series of speed bumps in a tight area with cars backing up and I was lugging the engine w/o slipping the clutch. As I went over the speed bump the bike suddenly knocked (I wouldn't call this a ping) really bad like I was in second gear. So I thought I was accidently in second, pulled in the clutch, downshifted, an nope I was in first. Strange. I'll keep a eye on this to see if it occurs again. I am sure I really lugged the engine, it just seemed different like I was running out of fuel. Maybe I need to get my idle up a little. Anyway I should have been clutching it.

I cut the leads and swapped them on the box.
My lights still act according to the instructions though.
I also heard the knock you described. It happened while revving the engine from idle. I have not been able to duplicate it since.
