Wild Things, PCIII Or Cobra

[hollywood]

Ok. I am going to be adding a K&N Filter to my Mad. I already have the V&H pipes. Had no problems other than it occaisionally stalls at inoportune moments. You guys suggested that it might be running lean and to add the PC

Now I have been looking at what's available
The PCIII - pricey
The Cobra - 179.00 on ebay
The Wild Things Fuel Injector Controller (Kuryakyn)- 189.00

Does anyone know anything the comparison of these units.
Which one is best.

Thanks

Dobeck TFI is another and the one Cadd has and the one I have. Probably it is a take off or Wild Things is, off this, however I have never heard of Wild Things..

I am happy with TFI, as this is my 2nd one, the first being on a 1500 Nad which was stolen.

How are you mounting the K&N?

The Cobra I think have upgraded to 4 pots, which is what TFI has. If there is only 3 pots to adjust, then I believe the modual is a bit dated, which isn't the end of the world, but you might like it cheaper.

I'd go with the PCIII, I beleive it is the only one that can be adjusted richer and leaner than stock settings. the others can only be adjusted richer than stock settings. Im relying on info I got a couple years ago, maybe some of the other fuel processors have changed since then.

I run the wildthing in mine. Very happy with it. It is manufactured by Dobeck performance. It is the exact same thing as the TFI, it is just marketed by Kuryakyn. My fuel mileage is great (steady 42-43 mpg) and the power is VERY EXCELLENT!

I also have had good results with TFI, increasing mileage to steady 41 to 45 depending on where and how I ride. Plus it got rid of the off idle stumble.

Dobeck is the guy that makes TFI's & they are sold under many names like Cobra, Wild Thing, and others.

While a Power commander may provide more adjustment and a little more power than a TFI, it usually doesn't. That's because at least half of them never really get set up right. To do it right is a time consuming process on a dynomometer where they have to ring the sh*t out of your engine for a couple hours getting it set up.

Say you change a rear tire for a different size, or move to a higher altitude, change sprockets*, or suddenly can't buy 93 octane gas any more? All your careful tuning is thrown out of wack. It'll still run, but now you've got to go back to the dyno guy and pay again.

The other thing I don't like is that they can sometimes get "scrambled" or "lose the map". I think this is a case of voltage spikes caused by a random hard start event. Maybe the engine is really hot one day, or really cold, or a battery cable gets a little loose, or the battery gets weak from doing a bunch of short hops around town. When that happens, the bike will run like crap until you either lift the tank and unplug the thing, or re-load the map.

So far I've never heard of a TFI having these issues. It may not be quite as versitile, but it's a lot less trouble, and you never need more than a small screwdriver to retune it. If it goes bad, the bike will still run OK, though I've never heard anyone on the forums say theirs went bad. I've heard several say their P.C. went bad.

Unless you're going racing, and need every last horsepower you can possibly make, I don't think the P.C. is the best choice.
(*not actually possible on a Nomad. Applies to most other bikes though.)

OK next question - what exactly is a "pot" and what does it do?

Its the adjustment dials on the fuel processor. You turn it to set the amount of richness or leanness. Its usually measured in the position of a clock, eg 1:00, 2:00 etc. Some brands have them some don't.

I have the Cobra and it's a simple 3 pot unit. I only adjust the first two as the instruction said 3/5/0 but I use a leaner setting than the Cobra recommendations something like 2.5/4/0. Two settings and the bike is running fine with V&H and Thunder round air kit -- it has a K&N in it.

If you get this one, get the one with the plug in connectors. I believe that the part is called a model Fi2000R. The earlier version has you crimping into the wires.

uh, yeah...

Those crimp-on things will eventually cut through your wires and the bike is gonna stop dead when that happens. I'd solder some pigtails into the wiring harness with blade terminals so you can unplug the unit whenever you want to.

Yup.

That's why I spent the little extra on the plug-in connector Cobra model. They connect between the plugs. They still sell the crimp on ones though and I would avoid those.

If you can solder you can save $50.

They didn't offer the plug-in models when I bought mine, BTW.

I had the TFI unit on my Meanstreak and really liked it and especially liked the online help and various settings from Doebeck based on specific setups. I had V&H Straightshots, Thunder Air and was able to get it tuned in very well. The 06 Nomad I bought from a friend already had the Cobra FI2000. I'm still playing from the stock settings of 3/5/0 as I don't feel it's right on and don't get as much help online with reports on various setups and tweaks but everyone seems to agree that stock is too rich, even with an air kit. I liked the idea of being able to tweak each without the download required by PCIII but thats a personal choice. If I was buying again I'd go TFI.

If I were to do it again, I might buy this one:

Looks like that one is only for the 1500. Doesn't say it supports the 1600. The question was asked a while back as to how I planned to mount the K&N. I am only going to mount the filter in the stock cover. No other mods to filter. Still not sure I have to go this route. Bike runs good except for occ. stalling in between 1st and 2nd gear.

I think the wild things module fits all the things you guys talked about. No crimping of wires, 4 pots (adjustable) I am leaning toward this one especially since it's only $189
