Check out the FJO Wideband ~$700...less expensive and looks like a more feature rich & accurate product.

I'm running a group buy on the FJO system. I have it built in my T-64 car and it works perfectly. I've already shipped the non-data-logging versions. The next shipment will be in early November and will be the new data-logging version. $665 delivered on the group buy. E-mail me if interested.
BTW, once you get used to knowing what the AFR is, you just can't imagine how you lived without that information -- kinda like getting a tach or boost gauge after not having one.
Every time you make a pull, you'll find yourself watching the AFR moreso than the tach or boost gauge. It's also interesting that when you make an adjustment on the VPC or fuel controller, you can see the results on the FJO readout, and if it's much of an adjustment, you can feel the difference during subsequent pulls. With the POSSIBLE exception of a boost gauge, this is the most important item you could add to your car for tuning and safety/durability purposes.

Are you selling them or you just doing a group buy? I like to know little more detail about FJO or see some pictures. I'll also I like to hear from more than just one person's experience.

Watch the magazines in the coming months -- probably early next year. Articles will begin to appear then, and perhaps people who only trust what they read in magazines will finally become awarew that EGTs are a useless tool for AFR tuning and a true wideband (like the FJO) is the only way to go.
I'm not quite sure about your other question, but I'm taking orders and shipping the units on the GB. Just doing people a favor, as I'm getting about $10 over my cost on each kit -- not even worth my time and trouble to answer all the questions, handle the checks, repack and ship everything, etc. If I were just trying to make money I'd be better off working on fries at McDonalds. LOL But I'm so gaddam tired of people posting the question, What EGT should I tune my fuel to? that I'm willing to try to help educate some folks by putting some widebands out there so people can see how useless EGT readings are.

The FJO system used the Horiba laboratory spec unit as a benchmark for performance. The FJO unit generates the same readings as the Horiba or other quality wideband systems. You can use the Horiba or other wideband sensors on the FJO controller if you feel the need to spend more money or feel it gives you some bragging rights. You will have to splice the wires though, because the connectors are different.
Accuracy of the FJO is better than .1 AFR over the range of 10.5:1 to 19.9:1. The sensor is heated, so EGT doesn't affect the reading. If I recall correctly, the update rate is 125 milliseconds.

I originally tuned my fuel system on a Mustang dyno with an integrated wideband (Horiba, I think, but I'm not certain). When I got the FJO unit I did a quick and dirty install on my car to test the FJO before I reset my ECU (by disconnecting the battery to make the electrical connections for the FJO install) and therefore risked messing up all my settings from the dyno tuning. The FJO gave precisely the same readings as the dyno wideband.
To me, that says something positive for both the FJO unit AND the Mustang dyno. Dynojet brand dynos are generally considered to load the engine to a lesser degree than it will be loaded on the street (at least with a heavy car like the Supra). Therefore, conventional wisdom claims that the AFR will vary from the dyno to the street or track. On the Mustang dyno you program in the vehicle weight and also do a "coast down" test so that the dyno can "learn" the drivetrain characteristics. As a result, the Mustang dyno is supposed to be able to simulate the real-world road or track loads. According to what I saw with the consistency of AFR on the dyno and the road, it seems that the Mustang system works.
BTW, with a Mustang dyno you can hold a constant load on the engine and tune at a steady-state load, or you can program a variety of loads or load change rates. IMO, the Mustang dyno would be a much more verisitle tuning tool than a Dynojet. I guess that's one reason that SP is getting a Mustang.

As I stated before, Horiba doesn't make the sensors! The Horiba brand name only uses the UEGO sensor, which, at your "group buy price", the senor alone would be more than this "FJO" unit...Boost Junkie said:The FJO system used the Horiba laboratory spec unit as a benchmark for performance.

So what's this about the "same reading" again? At least be straight forward with these people man...

I have encountered this belief as well, that wideband 02 sensors aren't accurate. I don't get it, as all true wideband systems I have seen have been very accurate. This includes Horiba, Motec, and the built in system of a Speed-Pro (or FAST) fuel system. In every case, you can trust the sensor.
Where did the belief that long sensor life=inaccurate readings come from? There are lots of myths out there.
So many skeptics when it comes to new things in the MKIV community. Every new idea that gets posted here always seems to attract 3 or more "can't work, bad idea, won't happen, it sucks" type of people.

Here is the classic MKIV "if it isn't the most expensive possible thing out there, it must suck" attitude. Do you look at results of testing or just price tag when you select a product? He said it matched up perfectly with the Horiba system (which is several thousand dollars at last check). But FJO must suck because the Horiba is more than three times the cost? SIGH.AZWildcat said:
True. A lot of old myths seem to lack any foundation, yet most people blindly embrace them. Just like my favorite pet peeve, tuning AFR based on EGTs. (Oh shit! You got me started now. )Where the hell did anyone ever get any fact-based evidence that this could be done with any measure of reliability? Yet soooo many people swear by it. LOL
That is not to say that a very experienced tuner such as SP could not use EGTs along with their vast experience with tuning Supras based upon the look of the exhaust smoke, the sound of the exhaust note, the general feel of the car, the Zodiac chart, the V-angle of the legs on the latest Hustler centerfold (Larry measures that carefully every month), and whatever other black art they may have developed in their thousands of hours of work on Supras, and nail the AFR pretty close without a wideband. But for someone without a LOT of tuning experience to try to go simply on EGT is insane, and people need to realize this for their own damned good!
