I'm Trying to find out if people are interested in doing something like this. I have made no calls or anything as of yet. I'm simply trying to gauge interest in such an event.



Here is the best retail deal I could find on the internet, I feel like a group buy could really bring the price down:

Interesting company, never heard of them before. Anyone out there used their products?

Seems like a pretty good deal, but that LED display said "tall 0.56" numbers". Seems to me that 1/2 inch numbers would be pretty small. Kinda cool, though, the LED could be hidden somewhere.

I'd like to hear about some experiences with them before I'll go with it. But if there is some positive out there, I'm down. Think they'd give me a deal on an EMS, too

 

what about the DIY guys in oz. Their wideband is cheaper.

thread on it. https://www.rx7club.com/forum/showth...t=diy+wideband

website. http://www.techedge.com.au/vehicle/wbo2/default.htm

several guys on the forum have them and they run $350AUS assembled plus $125US or so for O2 sensor

Thought that might help out some folks.

 

I don't think anyone has actually gotten their OZ wideband done yet. If they have they have not posted the results.
anyone care to comment on how well it all works for them?

 

The guys that build the datalogit are working on incorporating the DIY techedge wd kit info into the datalogit software to that it can be used easily in conjunction with the datalogit. They are also putting together one of the kits and will be testing it againts highend widebands to check for accuracy. If I were you guys I'd wait a little while for the results as its much cheaper than the FJO or any other wb on the market.
If you get it preassembled with the sensor and everything its about $300US if you assemble it yourself its only about $200US (this includes the sensor!!!).

If it tests good I think this is the way to go.

Wow that does sound good. If its of the same quality of the datalogit that would be a great deal. Any idea on the ETA?

 

Well, the kit is already out right now so you can buy it if you want at the techedge link listed above. I'm just waiting on the datalogit guys to test it. I just found out they will be testing the DIY wideband head to head with the FJO. I'll update the thread when it happends. I dont think it will be very long. From the way they are talking they already have the DIV kit and are in the process of building it. When its done they will test it so I'm thinking it shouldnt be to long.

STEPHEN

 

I'm interested in getting one as well, but I want the one I've seen somewhere online that has a digital A/F display inside the car.

Anyone know who makes that one ?

 

I have just completed installing the FJO unit. It is very nice and easy to install. The only thing that I did not get with the kit was a sensor boss and plug. If you are able to put together a group buy with FJO, I would insist that this is included. Although you can order the boss from Jegs, about $9, I think.

I went to a machine shop. I had some other stuff done and took the sensor and pipe there too. They quickly machined a boss and welded in place for me.

I believe that the DIY wideband O2 through the Datalogit group fell through. They were not going to be able to sell it at the price that they wanted to, so I think that they just dropped it and suggested that everyone go direct. But they are to test it vs. the FJO, as SPOautos indicated.

The display on the FJO is pretty damn cool and easy to read. I am not fully versed in all of the features, but from what I have seen so far, this is a very quality product.

I am going to use the 0-5V output from the FJO controller and input that into the Datalogit module. I haven't had the opportunity to datalog (with the wideband input) yet.

I am starting from the PFC bases maps and have just installed a midpipe. From the little bit of running around last night, the maps are very rich (at high RPM & boost I was reading in the 10s).

I'll have more time to play with it this weekend (hopefully log a few runs and take out a little bit of fuel).

On a side note, I need to play with the base duty on the boost control solenoid too (since I have installed the MP). I forgot about that last night and (DOH!) hit boost cut once...damn that is harsh. On the plus side, I put the silencer in my Apex GT and it did not boost above the set points after that.

The DIY wideband might be a good option for those that are comfortable with the electronics side and want to be very cost effective. I just wanted something out of the box with a specified accuracy, display and 0-5V output. The FJO was a good deal to me with no worries. I am sure that I will grow to appreciate more of the features and details that it offers. E.g., when you turn the key to the "ON" position, the display reads "Sensor Warming Up". Takes maybe 30 seconds, then it goes to monitor mode. I believe that it will also inform of when there is an issue with the sensor.

Probably doesn't matter to most everyone, but the quality of construction of the wiring harnesses, the controller case and display are excellent and seem to be made to take a relatively high amount of abuse.

 

Theoretically, the FJO could be incorporated into the the Datalogit could it not? It's fully linear? Does it come with a voltage to a/f ratio chart?
Michel

 

No problems. Totally straight forward.

 

The australian DIY WideBand is a tempting deal at about have the price of the FJO. I keep going back and forth between the two. I'm eager to see some comparison test results.

 

I've had the FJO for about 9 months. It may say 0.56" numbers but they look to be more like 1 inch tall to me, maybe 0.56" wide though. Plenty easy to read unless it is very sunny outside, then it is difficult.

The voltage output is not 0-5v, it is 1-4 volts. Datalogit can probably be configured to handle this though.

FJO says the unit can be mounted under the hood (though I wouldn't do this in an FD long-term) so I'm sure it can handle a lot of abuse.

I made a tailpipe probe for mine so I can attach it to cars quickly and easily. I also rent it out.

As far as the DIY, I'm sure it will work fine. However I haven't talked to a single person here or on the RX-7 list who has assembled it and got it to work, though a lot of people have bought it already.

Wade,

Have you hooked up a voltmeter to the analog output to determine it is 1-4V output? My range is a little bit different than this. The output is 0-5V, but the range of 10 to 20 will be in the neighborhood of 0.8V to 3.1V (linear to 14.7). With Datalogit, you can tell it what voltages are equal to what AFRs. I haven't had a chance to wire it up and datalog yet, but I will this weekend after I fix my boost creep problem.

My DIY kit is assembled and ready to go. Got an extra bung in the DP. Got the sensor. Got my DataLogIt.

Missing an incredibly difficult to get ahold of Sumitomo connector to go from the DIY WB Controller to the sensor (I odered one earlier in the week from TechEdge (the DIY guys), but haven't even been billed for it yet... I've also managed to get in touch via email with Sumitomo Electrical Wiring Systems in the US (you wouldn't believe how hard I had to look to find an email address). They'll send out samples of whatever to you, I just haven't written back with the part numbers yet.). And then also lacking a laptop presently (gotta take mine in to Gateway to get the motherboard swapped... smoke is usually a bad sign when dealing with a laptop malfunction...).

Once I get these last two things I need in place, I'll let you guys know how it all works out.

 

Thanks for the update Goblin, keep us informed. How was the assembly?

 

mmaragos, Wade,

From whom did you guys purchase your FJO unit? There are only a couple dealers in the states with others in canada, what was your experiences like with ordering and receiving? Did you get any price breaks? Did you guys also get the RPM output option and / or software package, or just the basic controler?
I'm still trying to decide if I'm gonna go FJO or DIY.

Thanks for the help.

 

Goblin,

Thanks for the update.... I have a laptop here you can use and I'd love to help you test, Cali's a great place to visit...
No, but really now. What did you use for a case for the DIY? Any pics?

Thanks!

 

http://fjoinc.com/automotive/dealers.htm

I ordered from Alamo. I got the controller, sensor and display. No price break.

You could just purchase the controller and sensor that would set you back about $600.

 

Heh heh... I know all about Cali, man. San Diego born and raised.

Assembly was cake. I had very little soldering experience before. I've built one or two little microcontroller things for homebrew robotics (anyone else familiar with the BASIC Stamp from Parallax?), but nothing difficult.

My soldering and electronics assembly skills increased tenfold building the WB and the display. If you follow the online documention and do all the tests, it's no problem.

It just went into a project box from Radio Shack. Nothing fancy.

Definately, if you want something that you plan on leaving in the car all the time, and having it look all professional and slick, buy one of the commercial offerings.

This is more of a "it works, it's cheap, duct tape it to the dash and remove it when done" kind of thing.

 

Goblin, you don't think it would hold up to constant use? Aside from the duct tape appearance, is it just too flimsy to get constantly bounced around, or do you think it would hold together?

 

Actually now they are offering a pre built one so you dont have to do anything but send the money. You can also get it in a box if you want. Even if you get it prebuilt and in a box its still about half price of a FJO. If the tests all come back that its accurate I'm getting one for sure!!!!

Later,
STEPHEN

 

Damn that thing is cheap. -buyer's remorse-

Oh well, if it tests out OK I know where to go next time. For that kind of price everyone should have a wideband on their FD from the start as a reliability mod.

 

Stephen,

This looks to be the way I will go too, DIY with sensor. Do you think that when you hear from the datalogit guys you can post here? I want to get mine ASAP.

Thanks,
Robert

 

I am interested in some type of wideband, too. If this ends up being a group buy, I am likely to join the purchase.
