Dobeck Techlusion

About 6 weeks ago, I upgraded from my first motorcycle, a 1992 Seca II, to a 2002 VFR from a fellow/former VFR-worlder Seadooloo.

In the sale, he gave me a Dobeck Techlusion EFI unit that he never got around to installing.

I am familiar with the Power Commander name, but not Dobeck Techlusion.

After a bit of searching I found the below website that explains how to install this unit.

Is it worth it?

Why or why not?

Thank you for your feedback.

I'm getting the picture....

Not a real popular modification.

 

Hello defector. My 2000 VFR came with the dobeck installed on it already so I really can't say what it would have been like before. The previous owner said he noticed it smoothed out the off throttle response and basically the overall powerband. I am new to the VFR world myself so I'm probably not a lot of help on this.

I'd say install it and if you don't like the differance take it back off, you basically got it free right? Oh, and if you install it, let me know what you think about the differance! Hee Hee.....

Your bike has a catalytic converter in the exhaust. In my opinion, screwing around with fuel mixture (as in aftermarket controllers) has the potential to do expensive damage. I would not mess around with a Power Commander or anything like it unless I had removed the cat.

 

Hello Rwortman! I'm not sure how an aftermarket controller is going to damage the catalytic converter. I am new to the VFR scene but I know in the automotive world that aftermarket fuel mapping controllers have been used for years without damaging catalytic converters. Maybe motorcycle systems are more sensitive though. I would appreciate more information on this if anyone has knowledge of it. I would hate to mess up my 2000 VFR because the previous owner did install a controller on my bike.

 

I guess I should restate that. I would not mess around with the fuel map on a catalytic converter equipped anything unless I had the use of a chassis dyno and an exhaust gas analyzer for a bike or the aforementioned analyzer and an able assistant for a car. Running your mixture too rich can cause the cat to overheat and destroy itself. How are you going to know if you have reached that point without either measuring something or waiting for the cat to melt down? That said, it is probably OK to juice the full throttle mixture a bit without hurting anything since you are not running full throttle much of the time anyway. I think if you haven't done any intake or exhaust mod's to upset the factory A/F ratio, then an aftermarket FI controller is a waste of time and energy.

 

I see what your saying now and it does make sense. I guess if you really want to know and make a performance enhancement worth wile it would be best to know the numbers. I really do not know how in depth the individual I bought the bike from got in its installation. I'd guess, not that involved. Do you think I should be concerned about anything or is it more of a feel good installation anyway with only minor performance increases and consequences? In other words, do you think it will hurt anything in the long run? Thank you.

 

I would say it depends on how much fuel is being added. It's hard to know without the aforementioned test equipment. At the very least I would run it in normal riding with the dials set to 0 and measure the cat temperature, then run return it to the settings it has now and measure the temp again. If the cat is not getting hotter than all is OK.

 

I've got little or no time to install/optimize/tune this controller. With a stock exhaust, I can't imagine it makes a big difference except in part throttle conditions where ignition timing is sometimes conservative.

If anyone wants to make an offer, let me know, or I probably won't get a chance to install this until next summer.

Thanks for all the feedback.

Do not be afraid. It doesn't add that much fuel. Use the settings supplied here- they are for stock bikes. It will run smoother off idle. And it won't hurt your cat.
Still running stock cans.... oh the humanity!
