hey phil......get the group buy going.

 

Ohh.. I might get into trouble..

 

the one listed for around $350 is for the controller and wideband sensor. its for integrating into a standalone engine management system. as stated about, the $500 is for a dual channel one. finally the self contained one with the guage at the top of the post is sold at around $520 for everything including the guage itself.

 

Can one sensor package from AEM be integrated with the EMS as well as display on that gauge? Looks like a nice clean way to have accurate AFRs... I don't like the idiot light style of Autometer or the Nintendo controllers with screens that come with other wideband kits.

 

to my knowledge thats what the single sensor and controller was made for. integrating into the EMS. i say yes, it can. might want to contact AEM directly (good luck) or call sean at torquefreaks a division of horsepower freaks.

 

Actually My understanding is that the AEM unit can be used in place of the stock O2 sensor because the controler produces BOTH, 0-5v wideband output for tuning, and synthesized 0-1v output for use by the stock ECU and/or std 0-1v A/F Gauges

 

As soon as its out I will get a GB going. Those are still in production. You will need their Uego kit to run this gauge, so prepare to spend some money

You wont need the stock 02 sensor if you are running a standalone system like the Power FC. You wouldnt need a wideband running the stock ECU unless you are using a Super AFC which I dont recommend.

Jason

 

so is it possible to hook the aem uego kit up to the datalogit hardware so it can be viewed on fcedit as well? i really like the gauge as well and would like to be able to use both options.

hey jason, since i started this thread do i get a discount

 

Jason,

What do you mean by we dont' need stock o2 sensor if we run stand-alone? I ahve PFC, how can I adjust to not having stock o2 sensor? Do I need dyno-tuning then?

POM HB

 

The Power FC does not use the stock O2 sensor. You wouldnt have to retune if you took it out.


I foundout the AEM gauge will be sold as a kit or seperate. The kit will be around $500 and includes everything you would need. ETA is the end of this month.

Jason

 

Sure, why not.

 

Hey,.. How about me??? FD3Virgin recommended me to start a GB.. j/k Jason.. I do appreciate you letting me and Matt do the GB on RX8 shiftknob..

After thats done, we'll donate small chuck for your website.. but if you could give a small discount too.. I would appreciated..

PHIL

 

Hey, *I* pointed out how accurate it is! If it wasn't for me, nobody would be interested in this thing in the first place!

Gimme gimme gimme!!!!

 

Okay guys, I found the gauge at a particular online store for $448 but I'm not sure what the policy here on posting links to stores and the like is. As long as one of the mods says it's okay (or they don't say anything to indicate that it's not) I'll post it up.

 

The gauge has not been released and I will price match if you find it cheaper. I have some on order and will let everyone know when they are in.

Jason

 

Well, it's at least listed on the site here: http://www.optauto.com/webstore/prod...tion=&back=yes

When you try to order one however it's listed as out of stock. I don't mean to be competitive or anything like that since I have no affiliation with optauto.com and I've noticed that links to particular stores or promoting one vendor over another tends to be a bit of a sticky subject around these parts. I just happened upon the info in my surfing and figured there had been some interest in it so I would pass along the news.

 

Sure wideband O2 sensor are great for tuning, but will the ECU actually respond to smaller, more accurate readings and compensate fuel accordingly? Or will it just "round-up" the signal to a normal O2's output? I think the ECU has to be able to read the UEGO output effectively to produce any real results. For instance, the MOTEC EMS was designed to incorporate wideband, one of the reasons that EMS is so accurate, and so expensive (around 10K I believe).

 

i was wondering something. the sweeping part of the gauge only reads from 11-17. does the led portion actually read lower? if our cars are supposed to be in the 10-11 range, it just doesn't seem to me like it would work, unless the led does read a lower number

Also carries the AEM Wideband Kits

 

I saw rx7store.net already lists the wideband kits.

 

All wideband o2 sensors come with a controller that interprets the voltage coming off the sensor and converts it into something that an ECU can use. The controller has to be calibrated for the sensor and then the ECU (assuming it has a wideband capability) has to be calibrated for the controller.
Now that you mention it that is a rather interesting issue. Honestly I have no clue whether the gauge shows the limits of the controller's output range or if it reads something lower than 11 it will send the proper signal to the ECU.

The stoichiometric air-fuel ratio for gasoline is 14.6:1 so most cars run up closer to that as opposed to the uber-rich numbers that rotary folks are running.

 

yeah, most turbo 4 cylinders i've been around have all been tuned for 11.5-12.5 so the gauge would work fine for them. i'd hate to buy a kit like that and just have the needle sit on 11 all the time

 

I called AEM to ask about the wideband guage range.

http://www.aempower.com/product_ems.asp

Notice the dial is marked from 11 up to 17. I was told by Jeremy in customer service that the digital portion also is limited to that range.

Is that low enough for us?

A local vedor also called, but the response then was that they were not certain and needed to ask the the engineering folks.
