Most definately! I'll see what ends up happening. The one taht you posted Señor seems to be impressive also, but not understand all the specs in heating placement of sensor, and etc, just seems like another thing I have to learn about.

 

I don't have the Motec Lambda Meter. I have the FJO product. This one doesn't look bad http://www.innovatemotorsports.com/ and of course it just comes out after I buy a widebandO2. I have no luck.

 

i have the greddy a/f kit. it comes with the 02 sensor and about a million wires with a data link unit. im pretty sure its not a full wide band, but if i buy the wideband sensor from wideband.com will the greddy unit be able to read the full potential of it?

 

I'm pretty sure you can't use a true wideband sensor with the GReddy. A real wideband sensor operates on a different priciple than typical 1V O2 sensors.

Another interesting tuning meter is the HKS "A/F-Knock Amp" (see the Japanese page http://www.hks-power.co.jp/products/...onitor/af.html). It requires an NTK wideband sensor (which you must supply). In an interesting twist, it also taps your engine's knock sensor signal (their web page says it works with the 4G63 engine). You can then hook up an earphone to this meter and listen to your knock sensor signal. The meter will also display the knock signal. It's fairly expensive (~$500) and I can't say how well either the A/F meter function or the Knock meter function works, but it's an interesting idea.

 

I have an FJO and run pretty much nothing but 112 race fuel in my Supra. My sensor is still hangin in there after about a year (knock on wood).

A buddy has the tech-edge and it looks really nice too.

When I got my FJO there weren't too many alternatives.

One word AGAINST the MOTEC... you can't datalog with it.... you need one of Motec's dashes to do that... BIG $$$'s.

With my FJO (and tech edge I think) I can datalog on a palm or laptop.

Well worth the price though if you want to know what your motor is doing - especially if you tune fuel and up the boost.

 

Thanks man that makes sense. I think I'll have to choose between the FJO and the Innovative one that Señor was talking about.

 

The HKS also a nice piece, but it states that it can only be used with the F-CON, and that thing is such a waste. I dont see why someone would want a standalone that only a certified person can tune it.

 

Ok my choices of come to either the FJO at 580 with no display(but with NTK sensor), for the Innovative Motorsports for 350, but I have to wait a couple of weeks?

 

YellwTyper --

What did you end up going with?

 

Do anyone notice the reading on the Innovative LM1 display is just too small?

 

Honestly you really dont even use the display. It is more practical to read your datalog after recording some logs off of your car. This is all theory I have yet to experiment. I'm going to attempt to tune a friends car and see how complicated it gets. It's seems a little tricky, but I'm pretty confident in what I'm going to do.

 

How do you figure out where you are rich/lean if the is no RPM recorded?

 

To clear up a few things; there are basically two sensors that ppl commonly use on tuner widebands; ie., not the ultra high end stuff that some tuning houses use; the Bosch or the NTK sensor. The Bosch is cheaper and the NTK is more accurate by a few percentage points; or so I am told.
The rest of the stuff is basically how well made the controller and display units are. I trust MoTeC as does many other tuning houses. You don't see many FJO's and whatnot there but that doesn't mean they aren't useful. I have seen an FJO and found the display to be quite a bit slower than a MoTeC, etc. The MoTeC is customizable for a huge range of things whereas the other controllers don't always have as much. Most guys tuning on the street mount the display and use it all the time. When tuning they simply watch the display and note where they need to make adjustments on the fly.

Yes, I do use the display to a great extent. If I don't, it is going back to the old days using ears to listen for pinging and eyes on the road and the rear view mirror for smoke. With the display, either I alone or a buddy of mine could watch the AFRs and get me to lift the throttle immediately if I am going lean. In the meantime, I could still rely on my age old visual and audio sensors to help me through the tuning. I stand a much better chance in saving the engine that way than going WOT and finding out too late before I even look at the the datalogs. Datalogs are there to help you to get closer to the AFR you want at certain rpms and loads which otherwise are impossible to achieve with our natural eyes and ears and our limited human memory when everything happens so fast and with so much data .

 

So it looks like the AEM UEGO has the advantage of having an output of 0-1 V for the factory harness, and a seperate output for the 0-5 V, eliminating the need to mount another sensor bung. So what displays can be used with the AEM, and who is offering them as a kit?
