are these units as good as a pc3?  a quick read tells me that i should be able to bolt on anything and the controller will compensate for it no matter the mod.  is this true or just clever marketing?

It's a doebeck in disguise.

The only way they'd be able to get around the hook a pc up to re-map is if they have an oxygen sensor somewhere in the exhuast to make a closed loop system similar to that of a car.

+1. It would be nice, but I will believe i when I see it.

It's out there and available. I've looked into it. I know Kenny a while ago was looking at home brewing something... (not meth or crack..) 

But the price is over $500

It's out there and available...bolt on?  Sorry that is what I was getting at. That would be sweet. If I did have a 700, I might opt for that out of the gate. Doesn't seem like it would be too hard to wire up, but I just had never seen it before. Thanks.

They are load based, but that has nothing to do with closed loop. Load is factors its gets from the stock pulse signal. You can configure them to be either more rpm based or load based for the switching points between the circuits.

There is really not any out of the box closed loop products on the market even the pc3 with wideband has no functions for closed loop. I have not hooked this up but i know it can be done if you take a dobeck and mate it with an innovate box you can get a cloosed loop setup. It wouldnt be as high tech as a car efi but it should work.

You guys shouldnt really knock these little boxes they work really well as long as the people you are getting them from have set the base map up right. I have put ours on quads with and compared them to a properly tunned pc3 and there was no difference in HP the only thing that these can not do is trim fuel. The on the fly tunning is much easier with any gen 3.
