wideband o2 question

[hottscennessey]

I've been looking getting wideband and getting an electronic boost controller quite some time now. when i was reading one description for a greddy profect e-01 i saw that it has the feature of:

"Can datalog the following for up to 3 hours * - see note: Boost, AFM input, AFM output, throttle position, RPM, injector duty cycle, boost control solenoid duty cycle, any 2 digital signals (wideband O2, narrowband O2, etc), any 2 analog signals (speed, knock sensor, etc), and any GReddy P/H gauge!"

I'm really interested in the 2 digital signals feature (wideband), i know for this feature i'd have to buy a harness ($15), but what else would i need.. i'd love to go this route if you can directly connect an o2 sensor to the harness... but that seems too easy to be true.. is it?

nope

you can not connect a wideband o2 sensor directly to the E-01. You MUST have the brains that take a wideband signal and then convert it to 0vdc - 5vdc.

But, if you are electronic savvy, the brain can be made for like $20 plus 80-120 for the sensor.
but I think you would need a dyno to calibrate it...

dang, it was a good theory, but now it seems like its just too much work. thanks guys

 

[hottscennessey]

okay, so i had just about given up on this idea.. until i found this.. it seems like a pretty good price for a wideband o2 sensor AND controller.. will this work, or am i looking for something else?

Innovate Motorsports LC-1 Lambda Cable

That innovate box is too huge. Try PLX, they offer smaller, accurate WB setups, and you can datalog it on your E-01 with the harness.

I have this exact setup, and the E-01 reads the same as my PLX AF wise. (Just get the information of what voltage = what AF ratio, plug that into the E-01 and it reads out your AF all the time. It would also read any other sensor you want as long as you put the voltage values in there, and tell it what they mean. (IE: if you want fuel pressure, you can put the pressure sensor on the AFPR, and then hook it up to the E-01. If the voltage is 1-5 volts, and that is 0-100 psi, it's going to calculate the pressure based on the voltage being returned by the sensor, giving you the fuel pressure all the time.

The E-01 is a great controller, and combined with the new Eman, is about the best piggy back setup I've seen lately.

thats cool to see that it works that great for you. But what i'm looking at is different from the innovate's giant box, its actually a wideband controller built into the wire, check out the link, its a little bit different.

Btw, Adjuster, which PLX model are you using, i've looked into their products a lot. They actually offer really good deals on the honda-tech websites.

you are talking about the LC-1 with the XD-1 guage.

 

[theDon]

my Innovative LC-1 (with XD-1 gauge) is pretty tiny compared to the LM-1

The new 6-in-1 Gauge-type AEM wideband has a 0-5v output built into the gauge/controller

 

[Adjuster]

PLX M300 is what I have. The red digital readout is easy to see, and it datalogs when hooked up to the E-01/emanage.

I am having trouble with mine right now, but it's a wiring problem, not a problem with the unit I think. (I'm just to busy to find the short right now.)

Worked great till I let some shop guys work on my car. (Don't let others work on Supra's, they just screw them up.)

where can i see this, and what is the 6-in-1 feature? I'm really looking for something with any type of datalogging.

I'm looking VERY seriously at this unit.. it looks so great, and i can run the application on my ancient laptop:

and i agree with adjuster.. NEVER let anyone work on your supra..

The AEM does not do any internal datalogging, but it does have 2 outputs -- a 0-1 volt signal designed to mimick a narrowband signal (so you could run it to your stock ECU and not get a trouble code), and a 0-5 volt signal used for stand-alones and/or datalogging.

The "6-in-1" feature on this gauge is really a combination of 6 previous gauges. AEM used to sell gauges in set colors -- white face, silver bezel. White face, black bezel. Black face, black bezel. Black face silver bezel. And then you could get 2 gauges in Lamda instead of AFR... Now They include a white and black face with the gauge, as well as a silver and black bezel. You can mix/match colors as you want very easily. There is also a switch to go from Lambda to AFR. Additionally, the old gauges had the harnesses hardwired into the gauge. This means you had to mount the gauge first, then run the wires all the way to your power source, and all the way to the wideband O2 sensor. It was a inconveinence to say the least. This new version has a plug at the back of the sensor, so you can disconnect the wiring from the gauge and run that first (from the engine bay into the dash if you wanted).

The PLX units also have the "narrowband" 0-1 volt setup, and a 0-5 volt wide band output, as well as many other options for either no readout, a readout, datalogging, and even wireless technology so you don't have a cord to your PC, it just has a USB wireless adapter. (nice if you have used a laptop in your car. I have used mine alittle bit with the Emanage, and it can get pretty congested with cords pretty quickly. (The E-01 controller and cords, power for the laptop. Line to the Eman from the laptop etc.)

I'm not using the 0-1 volt output since I have a good stock narrowband 02. (Thanks MCD Motorsports, nice price, and fast shipping.)

Another nice thing about the PLX is it's self calibrating, so you don't have to do anything but turn on the car. (I am going to re-wire mine so that it is ONLY on when the TCCS is on. Right now I have it on when the radio is on, and that is annoying, and uses power to keep it hot just sitting around listening to the stereo. My Omori gauges are also wired to the acc. switched wire, but that's no problem as I like to be able to read the peak points after shutting down the car, but not fully turning off the power. The E-01 is also wired to this power source, so I can pull my data, and change Emanage settings with the engine off.) I figure that the few times I need a free air reading, I can just turn on the TCCS, but not crank over the engine.

In any case, get a WB since it's completly the best tuning tool you have. It will not however save your engine from detonation, you need to keep an ear open for that, or data log the knock sensor if you have a way to do so. (Can be done, but I'm lazy, and don't have it wired up, and values entered to monitor for knock sounds that are dangerous.)

The datalogging is from a third (serial) output that you have to splice in a serial cable to use. I can't get the damned (datalogging) thing to work at all on a friends car. Tried every hyperterminal setting on the laptop too, the AEM instructions are worthless. I'd look elsewhere if datalogging by the wideband itself is a priority for you. Even if you could get it working, it isn't going to log the RPM, just A:F all by itself. It is a good wideband controller/display if you have another unit to handle the logging though...

okay i decided to go with the zeitronix, i hope i'm satisfied
