FJO UEGO group buy - Honda Prelude Forum

DirtyLude · 04-17-2002, 08:41 AM

I'm getting in on a group buy for FJO UEGO meters. We need to get $5000.00 worth of product together and we'll get a 14% discount off the advertised prices. If anyone wants to get in on this, please list the items that you want in a message to philipskeete@hotmail.com who is orginizing the groupbuy. He'll be able to give you more details regarding payment and shipping.

Kits and component prices can be found on the FJO website. There's also detailed specs on the controller. www.fjoinc.com

Personally I plan on getting:
Controller
Installation Kit
Datalogging Kit

I don't really need the display since I can use my laptop to display or the standalone to datalog the output. I'm also getitng the sensor itself from another supplier that's cheaper.

EDIT: For those that don't know, this is a Wideband O2 sensor controller that can be used for tuning.

So how much would one of these wideband setups cost me if I just used my laptop as a display (cheapest route right?)? I browsed the sight but I'm not even sure what all components I would need. Just a wideband O2 senensor and controller and software?

thanks

This would be the cheapest setup listed with groupbuy prices:

Controller: $311.53
Controller Installation Kit: $7.95
Wideband Sensor: $194.57

LED Display: $162.74
or
Connectivity Kit: $164.04

The Connectivity kit should replace the LED display, and is about the same price, but you'll need a laptop in order to read the display and datalog. You then have the option to get the RPM input as well and datalog a/f by RPM. The LED Display has the benefit of being simpler, it's just a 3 digit display and it's perfectly adequate to do tuning with.

If you have a standalone that takes a 5 volt input (pretty much all of them) you don't have to get the display or connectivity kit. The only reason I'm getting the connectivity kit is because I want to make some money back doing tuning for V-AFC or FPR installs on other peoples cars.

The NTK sensor is only $117.00 from thepartsbin.com so if you want to save more money, you can order the sensor seperately.

Don't forget that all this can be monitored on the handheld devices also (perfect for me). I wish I knew about this product before I bought my PLM. Anyone want to trade a complete FJO set-up for a PLM???? Hehehe.....

DYI01 · 04-17-2002, 02:01 PM

i am really interested in a a/f gauge. Is this almost $700 worth the cost of an A/F gauge? I am looking at a Greddy A/F gauge, i know it is wasy mroe accurate then most gauges out there, and it even comes with its own o2 sensor and everything.

DirtyLude · 04-17-2002, 04:34 PM

Unfortunetly the search feature doesn't work on anything but subject names on honda-tech.com anymore so I can't find any of the posts that talk about the greddy a/f meter.

Essentially the Greddy is an upgraded sensor, but it doesn't have any of the heater controls that would make it a true wideband sensor. O2 sensor accuracy varies wildly with the temperature of the sensor. I wouldn't call the Greddy meter accurate enough for real tuning. It's still more of a warning device, like the standard O2 monitors.

The UEGO sensor and controller are fast enough and accurate enough for real time operation. If you have standalone that can target a/f ratios in closed loop operation, you can run closed loop WOT runs with this sensor.

EDIT: Apparently someone is working on a plug in module for use with the Plug and Play ECU's, like Hondata and the AEM EMS. Hondata will be supporting and selling the FJO meter soon.

I am interested, but the price seems a bit high though..

DirtyLude · 04-17-2002, 08:04 PM

There were threads that talked about the Greddy meter in particular.

14% is actually a preliminary figure. That was the first discount that was offered. I've found out that FJO has offered others 20% discount so hopefully we can get the better discount, but it may not be possible at this time.

Quaalude · 04-17-2002, 08:26 PM

this is a good deal...too bad there wasn't a groupbuy when i bought mine...i paid $800 for the controller, installation kit, sensor, and display...could have saved $120....this is worth it if u are a serious car enthusiast and would like to know your car's correct a/f

DirtyLude · 04-18-2002, 07:43 AM

Since FJO will not deal with us directly, we must go through a dealer. We're unfortunately stuck with the 14% discount.

Spocko · 04-19-2002, 07:05 PM

Hey dirty...let me ask you a few ?'s about this, as I am a little unclear...

I have a stage 4b Hondata setup, and I know that they sell a WB O2 sensor for it to hook up and then read with the labtop. Well, I was wondering, what would I have to buy from your list above to make it happen, as I am in dire need of a tuning device other than a dyno.

Also, when you say closed loop, do you mean anything other than WOT(WOT= open loop right?) I want something that will show me if I am running lean or rich ALL THE TIME, in non-boost part throttle apps, idle, WOT, full boost, etc. So let me know what I would need! Standard A/f gauges and EGT gauges are too vague and inaccurate, and they don't tell you crap unless you are at WOT. I need tuning ability especially running a high boost, high Hp DAILY DRIVER.

Thanks!

(Sorry if that is such a stupid ?> diff. b/t open and closed loop, but I just don't completely get it. Also I think with my Hondata system I clicked for it to run only in closed loop all the time, so I assume then that the system is ignoring the O2 sensor readings and just using the values inputted into the tables that Hondata burned onto their chips???)

DirtyLude · 04-22-2002, 08:22 AM

Closed loop is when the ECU adjusts fuel based on the O2 sensor readings. The standard O2 sensor is too slow to adjust fuel at anything other than steady state cruising and idle. It also isn't accurate at anything other than 14.7 a/f ratio so it can only really be used for closed loop fuel economy / environmental driving. If you have a standard O2 gauge, you'll see the car has gone into closed loop when the fuel starts cycling back and forth, rich to lean while cruising.

Closed loop is really only a daily driving feature. Hondata and other standalone tuners have the option to turn off closed loop all together and rely on the fuel maps alone to determine fueling requirements. It will cut down fuel economy and emmissions some, but it's slightly better for a race map.

The UEGO sensor is fast enough and accurate enough over a wide range of a/r ratios that you can run closed loop wide open throttle. Your Hondata will determine how much fuel the engine needs based on the O2 sensor readings alone.

All you really need is the controller, installation kit, and the sensor from www.thepartsbin.com It will allow you to hook the controller directly up to your Hondata. If you have the datalogging option you could datalog the a/f ratios and injector pulse widths reported by the ECU and build a map based on it.

If you want to be able to view the a/f ratio without having to go through your standalone datalogger, or if you don't have a datalogging option, you'll need either the display or the connectivity kit. The basic display just shows you a 3 digit number that corrosponds to the current a/f ratio. The connectivity kit does the same, but you need a laptop or PDA to view it and it gives you the option of logging the data.

I just want to note, that the wideband sensors should not be used as a bandaid. You really shouldn't just install it, set you standalone to do closed loop all the time and forget it. You should really use the wideband to create a good map and then use the wideband only when needed.

I don't plan on running this in my car all the time. There's lots of people around here who are going with standalones and I'm going to use it to tune other cars as well as my own.

Spocko · 04-22-2002, 01:45 PM

That's basically what I want to do- get it to tune my car's maps and then rebuild the maps accordingly. After I know that my car is running perfect, I will more than likely just disable closed loop and run my WIDE-O2 tuned map. I probably will leave the sensor in there with everything hooked up, but not rely on it after that.

I would like to be able to monitor the A/F without a labtop as well as hook it up into it, so then I think I need the following(and yes my Hondata stage 4b has the datalogging option already built in)...

controller
installation kit
the o2 sensor from www.thepartsbin.com
display

So I don't need the connectivity kit then right since I already have datalogging abilities, and the controller will hook up to the labtop.

Let me know if this is right, and then give me a price on everything above except for the sensor from the PB.com

One more thing...

1. When will this buy being finalized(How fast can I get this sweet portable dyno)
2. Is it harmful to leave it hooked up 24/7 like a regular o2 sensor? I really don't want to be switching all the time. I hope this replaces the 1st pre-cat o2 sensor, because with my obd-1 ecu, I don't think it monitors the post-cat o2 sensor- right?

DirtyLude · 04-22-2002, 03:30 PM

The prices are just up there ^^^.

Anyway, all you really need is:
Controller: $311.53
Controller Installation Kit: $7.95

Then get the sensor from partsbin.com. You only need the display if you want to view the a/f ratio realtime without having to look at the datalogs.

LED Display: $162.74

Last time I checked, Hondata does not have an autotune function. It means your still going to have to interpret the results from the datalog and change the maps to make a good map. That's not too hard and Doug from Hondata promised a write up on how to do this.

I wouldn't turn off closed loop altogether. It's still good for cruising and gas mileage. If you really want to save fuel you can try to really drop the a/f ratio while cruising as long as your EGTs aren't getting too high.

The sensor itself isn't degraded by using it, it gets contaminated in the exhaust, so if you're going to leave it in there, you might as well use it. The sensor should last 60,000 miles before the accuracy starts to really degrade.

Yes, this replaces your primary O2 sensor. If you're using Hondata your secondary O2 sensor is already totaly ignored. You might as well pull that thing out and plug the hole right now.

The details on the groupbuy you're going to have to get from the guy who's organizing it. I have no idea how close we are to the $5000.00 mark. Hopefully it's soon, cuz I'd like to get it quickly myself.

Spocko · 04-22-2002, 10:15 PM

Yeah that is cool- I can make my own maps, but to be able to actually see what the hell is going on at all times is more than worth it's weight in gold to me, especially with the T. Basically, I will run with my 17 psi P72 H22a Hondata maps that Doug already sent me that he did some tuning on, and with the sensor running(even though I will be ignoring the results for the Hondata in terms of fuel control source), I can see if the maps need adjustment and where and by how much by seeing what the O2 sensor is reading with that display. So it is kind of a way for me to double check my maps as I change them. I knew that it wouldn't "rewrite them" as the readings came in, but right now I am in the dark so to speak, and tuning off an EGT is way too hard. As long as I got this sensor, I can get my A/F settled, THEN I can worry about tuning the cam gears and so on.

This is really going to be a sweet addition. Thanks! Do you have any idea when this guy that is doing the buy is planning on gathering $ and moving forward? Personally I don't care if he gets enough people or not, I need to get this thing and display anyway.

DirtyLude · 04-23-2002, 07:37 AM

I don't know when he plans to move forward. You'll have to talk to him directly.

I've been to the dyno to tune my own car once and borrow their wideband and I'm already tired of it. I'd rather not hand the dyno shop anymore of my money.

DirtyLude · 04-29-2002, 01:10 PM

The group buy is now at 15% and is going through Hondata. Thanks to Doug at Hondata for helping us out and thanks to Philip for organizing all of this. Orders are being taken, now.
