Anyone have any experience with either of these? I have actually heard it is the same unit, but I really have no idea. I realize Dynojet has an option as well, but I have no interest in that. Is there really any difference between any of the wideband units?

I guess my eventual plan is the hook the wideband up to a SCT Raptor datalogger and if anyone has any reasons why it wouldnt work that would be good to hear. Thanks.

I have had the same FJO in my current Lightning and my last toy. I have been totally happy with it, and I prefer the display over everthing I have seen so far.

Here is a pic!

What do you want out of a wideband (looks wise and accuracy)? I have a customer that seems know quite a bit in this field. I can ask him again with what he went with and why. There are the very well known processors for tuning shops if you want to spend the money, but seems like a regular user on a budget has to many questions and decisions as usual, as you never know what you may get.

Bob,
I believe the new FJO units look like a standard round guage. I'm not sure if the technical part is the same or not.

 

FJO is definitely a better product. The read-out is better than any (especially the Dynojet unit). Another brand to consider is a Horiba, but that is $$$.

If you are just afraid of running lean and need some rough estimate of your AF condition, I would also suggest either an EGT gauge or a regular AF gauge with a pigtail from Gadgetseller.

 

My FJO has been on the money (+ / - .1) with two different dyno widebands. I have been running the same sensor for two years on daily driven vehicle and so far so good.

 

Why are you not interested in the Dynojet? IMO, it's the best wideband on the market, especially for the money. It has some really cool features such as an LED warning lamp in the gauge you can set to come on at a specific A/F, and it has the ability to trigger any kind of electrical device based on a specific A/F ratio.

 

I have the AEM UEGO gauge-type controller. I think it is a great product, accurate to what the dyno has read. All the electronics are in the gauge pod which is a plus to me as well. You can also log the air/fuel through a standard serial port to check if your lean going down the track.

 

I already had the FJO so it was no brainer for me. The dyno jet has some very cool features but I really like the FJO display. Hopefully FJO will up date there wideband. I would really like to have the ability to see a warning light if the A/F is over 12.2 at WOT.

I've had a FJO, and now have the DynoJet. I liked the digital readout of the FJO, but I really like the round autometer guage of the DynoJet. Both worked great for me; I would have to say with all the features involved the DynoJet is the better. At least for me it is.

 

There seems to be some confusion. The latest FJO unit is the same as the AEM pictured. I have no knowledge of an older FJO unit that may be different, which seems the case from a few replies.

 

I have heard that elsewhere, too. Technically the same, but with different logos?

A reader's digest version of why I am not interested in the WBC is I am an ex-employee and the WBC is a bit of a sore spot.

Those that have either of these units, what kind of outputs do they support?

Denny -

This is the optional FJO display, they still sell the digital display like I have though.

 

Thanks Bob. This will clear things up for people reading and interested.

I'm not positive if AEM and FJO are the same units, but they look very similiar. Looks like a call to one or the other is in order.

 

I have the AEM wideband and use the serial datalog output at the track. It is just a text file with a series of a/f ratio numbers updated many times a second.

The data output on the Dynojet unit includes an RPM reference which would make it much more usable as a reference as far as being able to see a/f ratio compared to RPM.

I don't know if the AEM could be hooked up to the SCT raptor datalogger but if it could, it would solve the reference problem.

 

I have the AEM, and love it. It was really easy to install, and works great. Best of all it fits into you pod.
