But if this is as easy as it looks then I might be in to it.

What, exactly, are these two wires doing?

And, semi-related, does your Ultra have two O2 sensors? Mine only has one, on the rear header.

This is plug n play. Simply put.

Ok lean is mean. Too a point. Go too far and you will end up with burnt motor parts. Understand that all of our bikes come "EPA lean" which is between mean and burnt.

This gives you excessive heat off the motor and exhaust. It also, means that there is not enuff gas in the mixture when you smack the throttle open to rev properly. You get the lag then rev. A motor is a big air pump. You twist the throttle the throttle body opens and allows more air to enter the motor. However, due to lag with the epa lean mix, there isn't enough gas to accomodate the air. It leans out till the injectors give you more. Results = poor throttle response. These correct that by fooling the stock ecm into seeing a different resistent measure off the O2 sensor. This changes the a/f from 14.2 to 13.6 across the board. The ecm will still adjust to changing atmosphere as it does now.

There is some resistors and whatever in the 2 wires. Mine has 3 cause I have to ground the rear.

Both my bikes have 2 sensors. 1 per pipe.

I'm not sure. Email him.

I paid $100 per set for mine. The problem with trying to make your own. Is that there are very strict criteria you have to follow when dealing with O2 sensors. I think its something like you can't soldier, have to use the special connectors, etc. Certainly there isn't $100 worth of parts but consider that you're also paying for the R&D they do. Which is alot. I know one of his 3rd party testers he uses for certification.

Nightrider site is amazing. Scroll thru the first link I put up. He's got tons of info on everything from spark plugs, motor oil, etc. If you have any questions, email him. His name is Steve and he is very helpfull.

i'll agree that he seems to have put a lot of time and effort into these and picking the right voltage. seems dependant on harley epa facory tuning and guys not wanting to shell for a pcV.

What does it do exactly?

Tmall · 11-24-2009, 04:41 PM

Just checked out the site. Seems to make a ton of sense, and its cheap.

I may look into this over the winter.

You running ECMspy at all?

Gas Man · 11-24-2009, 04:54 PM

I have given it a 88% endorsement. Will complete my endorsement once I get it added and test rode to the Ultra.

This messege has been approved by marko138.

Marko, I was going to use it, but it doesn't work so easily on the 08 and up bikes. You need to buy conversion software to write to the ecm. Its not particularly expensive by any means but, like you I'm not very confident with messing around with fuel mapping.

This just makes it run a little richer throughout the rpm range by making it think its getting more air than it really is all the time.

Seems like the smartest way to overcome the dynamic fuel injection, just change the reading of the probe. I don't see how the bike could compensate and over ride it.

I'm going to get in touch with him and see what kind of buell specific advice he can give.

Right on.

I keep thinking about getting ECMspy so I can do my own TPS resets too.

I'm interested in what he says. He shows that he has some limited ViED version for the buells but don't show them in the table where you purchase.
