Talked to daytona twin tec, they said that in about a month they are going to release a dual channel wego unit. This will allow o2 sensor in the front and rear cylinders and no more front cylinder trim. Their tcfi system will be a true closed loop system with wide band 02 sensors for each cylinder. They said that current owners of the tcfi can send in their ecm and for a upgrade fee have it loaded with the software to handle the two sensors. You will have to buy an additional sensor.

Anyway, thought you all might like to know about this.

I am not affiliated with the company in any way.

Sweet.....this will most likely be an option for me. I wonder if it will be of any use to the guys that are running dual independent runner intakes.such as myself. With these setups you dont have to do a front cylinder tune. I wonder if having the O2 sensor in the front on these setups will improve the tune or not?

Tuners.....Whatcha think?

My 04' RK does not have sensor bungs in the exhaust. What would be the best way to approach this? Weld bungs in, have the pipes rechromed? Or buy new pipes with the bungs installed?

I had the bung welded in my pipe. If its done right it wont mess up the chrome. My father welded mine in. Welding is not my thing. He's pretty damn good at it though. You put us together and we can really come up with some stuff.

Bob,

If you go with new pipes, check out the Rinehart true duals. They come with the bungs in place.

Yo wyodude,

What parts of ol Virginia are you from?

As far as the new DTT setup coming out... I'll probaly wait a lil while and see how it turns out.

www.hackerpipes.com can weld in O2 bungs on their headers. Having bungs welded onto your stock headers would cost the least. If I remember correctly you are supposed to weld them at a 30 degree angle to the flow of the pipe and within 8" of the head.

I've been thinking about getting the WEGO system. I've got the SERT already. The WEGO would be great for fine tuning the AFR. But I guess the way I'm looking at it now is that once you've got the AFR right, there are always a few ponies left in dialing in timing changes thoughout the rpm range with a perfect AFR. Unless of course the ponies left by just modifying the timing only show up in the unuseable rpm range of my TW5-G cams.
And really the only place you can do and monitor that is on a dyno. At least in a timely manner. Of course there is the option of recording knock retard on the fly using a laptop and playing with it that way. So I'm comparing a good dyno remap to the cost of a WEGO. As of now I don't plan on making any more engine mods in the near future.

What are ya'lls thoughts on this?

Since i'm going to do a 98 " build soon i was going to get sert, is somthing like this better? Does it tune it's self? Welding bungs in for oxy sensors isn't any bug deal. I guess this has me a little confused so i hope my question isn't to stupid.

Self-tune is a little misleading. You still have to get on a computer and enter in values. But it is a good system if you have two O2 sensors, one for each header pipe.

So would you be better off buying this and spending a little more money than getting the race tuner and trying to find someone that can tune, plus dyno time?
How hard is it to get this set up ? I don't think adding the o2 sensors would be a big deal if you have a mig welder.

Check out the site http://www.daytona-sensors.com. There is a lot of reading available there. BTW, my bike is running much better now. Picked it up today.

It is still a great system with the one o2 sensor. You still need two bungs in your exhaust and they are very easy to do.

The 2 o2 sensors, a duel runner throttle body, and true duel exhaust will in fact allow you to tune each cylinder as a separate unit, but you need to meet those three requirements.

As far as sending my ECM back to them I would NEVER do it. They are the most unreliable, nonsupporting, non Tech support vendor on the market. They SUCK big time.

Great unit, but you are all but on your own with it.

Good info to know about their service.

DTT Service

Sorry LAF but I've got to disagree. When I got my TCFI unit the WEGO wouldn't work. I talked to Chris and he had me send it and the ECM back. Next day I got a call that both had checked out fine on the bench. It turned out the wires from the probe we in the wrong pins on the plug to the WEGO. A manufacturing error.

I know the history with DTT and their support but that's my personal experience. Maybe I caught him on a good day but I don't think so. We had several calls over this and he seemed to really want to help.

I just couldn't keep my mouth shut anymore on the DTT Service thing.

I rode up to Daytona Twin Tec one day and asked about their ignition. Chris spent a good deal of time with me and gave me a real education on HD ignitions.

I bought a TC88 ignition at dealer cost, he installed it for FREE, and when I told him I really didn't have the money for the programming cable, he threw it in for FREE saying "You'll want this."

They also let people download updated firmware and tuning software for FREE from their web site, "Crane Cams doesn't"

It's a great product made by good people. They don't have a dyno and can't tune your bike for you but they will refer you to someone who will.
