it looks like a pretty nice unit. How much is it? i haven't heard anything about it, but i'll give my observations on it.

First, it does have an analog 5v output which is important.
It has its own display which is nice.

It only reads to 16:1 afr, which is pretty much all you will need, though i run mine up to about 16.5 :1 @ cruise, and some people have cruising afr's as lean as around 17:1 so it would be nice if it would go a bit higher so you can actually see the afr's if u tune above 16:1 like some of us.

I would find out what kind of sensor it uses and how much they cost as sometimes they use a certain type thats way more expensive then the Bosch sensors that can be found about anywhere.

I didn't read the manual, but some of the widebands out have scheduled calibrations that help extend the life of the sensor and keep everything more accurate. This might be something you would be interested in, and the unit may or may not have it.

And lastly i didnt read anything about a narrowband output. I have one and have never used it and probably never will, if you are going to tune your cruise maps then this is no big deal.

Dudemaaanownsanrx7... you are turbo'd right? 16's on AFR just sounds lean to me I havent heard anything about that. Ill look into it though if it really does help on the MPGs cruising. The email that I got from NGK said that is compatible with both the NTK and Bosch O2 sensors which is pretty cool. The calibrations are automatic kind of like the AEM and that helps the sensor life but you can also free air calibrate which they claim helps with accuracy. As for the narrowband there is nothing.

Anyone else have some input.

Yeah i'm single turbo. There are quite a bit of us that run lean cruise afr's and have for years. You can run it as lean as the engine will allow without bucking. It helps keep carbon build up down also. Under boost those afrs would be bad, but for cruise its not an issue.
