I really don't wanna sound impatient .. Buttuh, the old thread has dissapeared in the archives ... So what's the status Dave?  | ||
| Daves |
No news yet. | ||
| Daves |
Got an email from George today. They are still working a couple things out but should be done real soon. Dave | ||
| Barkandbite |
George mentioned he's in the final stages of testing the reflash to eliminate a small issue that is not easily reproducible and minor in nature, but he wants to get it perfect. He estimates this will be done by next week. He mentioned he would offer free re-flashes to anyone who has the current revision level. Chris | ||

and to continue the tailchasing: will the box be equally useful with the stock and "race" ECM? | ||
| Oconnor |
my question exactly. I emailed techlusion asking them, but as of yet I have not heard back from them. | ||
| Barkandbite |
I spoke with George. He is not officially testing on the Race ECM as, per a paraphrased version of his response to me, "...the race ECM is just that -- an ECM designed for race applications and/or addition high performance modifications." Not to say that the Techlusion has any issue with performance modifications, but it's not tailored specifically to the race ECM. He mentioned that while they have not officially tested with the Race ECM, he has a few people using them with the odd CE light issue. Basically, I believe he's saying that it wasn't designed to work specifically with the Race ECM, though he knows of no reason it won't. However his flash of the chipset in his unit is based off the stock ECM. You figure it out. If it doesn't work with the Race ECM, it's not his issue as he doesn't officially support it. YMMV. When I put the race kit on, I got a nasty midrange hole. I'd gladly give that up, switch back to stock and add the techlusion. That's what I'm going to do. Chris | ||

Unfortunately, I have a great torque and hp curve right now with the race ecu. It just leans way out at 5000 rpm. I may stick in the stock ecu, if I still have it, and dyno that to see how much goes away. But so far with the set up I have, I am afraid to change anything to lose the power and torque abilities in its low and mid range. | ||
| Fullpower |
o connor, what you are saying is that you have a defective race ecm? by "running lean above 5000" with the race ecm, and problem solved with stock ecm, than we have no alternative view then that the race ecm is defective, right? | ||
| Oconnor |
Sorry, my post is a little confusing. I think the race ecu is fine, just that with my mods, k&N with a drilled air box, and custom exhaust, it runs great up to 5000, at wjich point it leans out all the way to redline. I don't think it's defective. What I meant was that if I have to use the stock ecu with the techlusion then I need to dyno the bike again with the stock ecu to find out where the extra fuel is needed. And I believe that with the mods that I have and a stock ecu there is a big hole somewhere around 3800 rpms. Exactlly where I don't want one. I have no Idea right now where the bike would run lean or rich with the stock ecu in it because I haven't thrown it on the dyno in that form. As of yet anyways. $35 a run around here. Good way to burn up cash. | ||

Dobeck seem to feel that Buell have simply 'dumped' a bunch of extra fuel in the midrange of the race ecm. I suspect that this will make adjustment of the TFi coupled to the race ECM difficult. Also, there is the matter of the warning lamp coming on for those who are using the current TFi with the race ecm. Weather or not this will be sorted by the new revision is something we will have to wait for. (Message edited by trenchtractor on November 06, 2004) | ||

Oconnor - I'm in exactly the same position as you and I am eagerly awaiting the results on next version. I'm running the race ECM but still have the stock one on the shelf. I really don't want to get the TPS reset again so I'd like to stick with the race ECM. If they don't fix the light problem, I won't buy it as that would drive me nuts. If it proves to work well with the race ECM, despite what Dobeck says, I will definitely buy one. If it doesn't, then I'm undecided as to what I'll do. | ||
| Daves |
You could switch back to your stock ECM without resetting the TPS. It already knows your bike. | ||

Just got the new tech unit in, will be installing it tommorrow,let ya'll know how it works, is 'sposed to not turn my light on,(with my race ecm), can't wait! | ||
| Easyflier |
Trench, that is supported by the map that was made for my PCIII. We actually had to take some fuel away in the midrange to maintain the best ratio. I'm waiting to get some more feedback before I try a techlusion box on either of my bikes. | ||

The Buell 'race' ecm is like any other H-D ecm download. It is programmed for specific OEM combinations and any time you change one of those variables, i.e. aftermarket exhaust with different flow characteristics, etc., it is hit or miss whether or not it will work. Correct me if I am wrong, but all the techlusion box does is alter the ecm signal and break up something that has the potential of being infinitely programmable, back into something with rigid parameters, like a carburetor. Anyway, my point is, I have heard rumors of a completely programmable 'race only' ecm available through Buell that is like the Screamin' Eagle programmable race tuner, the only difference being that the parameters are adjusted through software, rather than a mechanical switch.  | ||
| Trevor |
 Uhh... was it something I said? | ||
| Ingemar |
How many replies do expect within an hour?  I think your right about the race ecm. I don't think the programmable race ecm is a rumor, and I also think it will not be available to the public. The reason I want the techlusion box is its user friendlyness. I don't want to fiddle with cables, software graphs and I don't know what else. Set 4 knobs and be done with it. | ||
| Ortegakid |
Put the new one in, works perfect, no lights as of yet ,won't know 'till sunday spirited ride, keep you all informed! | ||
| Jerseyguy |
Ortega - Let us know how it goes. I'll be waitin'. Dave - Is that true? I can plug my stock ECM back in without a TPS reset? | ||
| Countryx |
I did. | ||
| Tank_bueller |
Ortega: Eyes are watchin' Talkin' out my Ars....... Tps reset is for the new ECU to meet your bike, like shaking hands. If you plug in the old ECU, it should be set to the same parameters as when you removed it???? someone correct me!!!!! tank | ||
| Trenchtractor |
Ingemar hit it on the head... For those of us who understand a carbie, the TFi is the go. The PCIII route is great for those with the extra cash for a more expensive unit and the dyno time to set it up. | ||
| José_quiñones |
The Race and Stock ecms can be swapped as many times as you want on the SAME bike without having to reset the TPS "Zero" setting. Both ECM's have the same "Zero" setting for that particular bike stored in their memory when they were first setup. | ||
| Rigga |
if dobeck feel that buell dumped a load of fuel in the midrange,i take it that makes the tfi box pretty redundant as it cannot lean off the fuel rate at any particular point,only increase the fuel injector duration...can understand the problem with the race ecm in that case,as it has increased fuel supply over the road ecm,and will only make the midrange overfuel situation worse....but this is for standard bikes right?...if the exhaust has been changed say from the buell item to a free flowing straight through system,and the airbox modified to increase air flow to the motor, that would lean off the mixture enough to warrent an increase in the midrange?or is it so rich it would never need increasing?......anyone carried out a dyno run with a/f meter to test this out?....pretty interested in the techlusion but really want to keep the race ecm on the bike | ||
| Trenchtractor |
Here you go Rigga... Ask and thou shalt receive...  No prizes for guessing which is stock ECM and wich is the Pro Series... Anyhow, these are both with a 2" straight through protoype muffler that will never see the light of day since it was pretty much just plain crap. But you get that on your first atempt. | ||
| Ingemar |
Brad, Care to give more details on that bike? k&n? airbox mods? | ||
| Jerseyguy |
Jose - Thanks for that info. I think I'm going to get the Dobek unit. Question: Would a "perfect" FI system have an A/F ratio that is flat line at 14.7, or is that too simplistic? I'm assuming a warmed up engine. | ||
| Oconnor |
Rigga, I did and posted it somewhere, I can't find it to link, but anyways with a k&n, drilled air box and custom exhaust and race ecm, the mid range was perfect (a/f) but from 4800 up got from bad to worse. 19 to 1.... Low rpm's was a little lean as well. Hopefully the techlusion box will cure it. But my only question left is, and the guys from trojan could probably answer this since they brought it to my attention. If the buell ecm will learn eventually to over correct a PCIII and need to be reset every once in a while. won't that same thing happen with the TFi? | ||
| Ingemar |
Question: Would a "perfect" FI system have an A/F ratio that is flat line at 14.7, or is that too simplistic? I'm assuming a warmed up engine. Stoichiometric is the perfect combustion, but for reasons I don't understand not perfect for max power. That would be around 13 or 13.5:1. But even that is too simplistic I think because there is a lot more involved than just A/F ratio. |
