Best Wideband setup for EvoScan Logging/ecuflash setup?

[ohmygahitsjosh]

So unfortunately with how much technology has advanced since this board has been around sometimes its hard to find out what works and what doesnt.

My main question is this... I am looking to get a wideband o2 setup for my 98 gsx now that I have had to replace a blown t-25 and decided to just upgrade some things while the car was down...

I guess I dont really understand HOW to log the wideband o2 at this point, Ive spent the last 3 or 4 days researching the boards and looking thru various wideband setups trying to figure it out and as pathetic as it may sound, I still dont understand.

There's 3 setups ive been looking at...

AEM EUGO 6 in 1 set up
LC-1 w/ db gauge setup or similar gauge
PLX SM-AFR + DM-5 AFR Combo setup

My main concerns are:

1. Id LIKE to be able to have the wideband available for monitoring all the time while driving which is why I want to have a standalone gauge.

2. Id LIKE to be able to log in EVOSCAN because i feel it would be a lot easier to get a decent tune with the data collected and not just with me visually watching the gauge while Im doing pulls.


Some other thoughts are the PLX system says it has the 0-5v output as well as a 0-1v output so you can use it in place of your stock o2. This initially was a selling point for me because I dont have any welding experience and thought itd be convenient to just pop the wideband into the stock bung. BUT after reading a ton of info on doing this I am inconclusive as to if running one there is a smart idea or not... I have read a zillion posts saying that its bad to run it there... but none of those people are talking from experience.. and the people that HAVE posted from experience are 99% of the time saying that theyve had theres in for as much as 20k miles and had no issue...

I wouldnt think that a company would bother releasing it advertising it as a stock replacement if it was not able to handle it? But I could be wrong... maybe I could get some up to date input on this especially from people who has run and or ARE running it.

Also if someone could clear up HOW you would log from any of these into a laptop logging with evoscan it would be amazing. I only currenly have a mac laptop but I was assuming you can run windows xp in parallels and evoscan would run fine... and I dont have a serial port on my laptop... and I assume that evoscan would be collecting the data from the usb port that the tactrix cable was plugged into? Can it log from multiple ports on your laptop? Perhaps a serial to usb adaptor is needed then?

Also if someone could clear up WHICH tactrix OP cable would be best to use for logging and flashing with an evoscan/ecuflash setup for a 98 GSX. (I read on ceddys ridiculously long thread that 2.0 is good but when I was on the evoscan site they dont even list 2.0 as being an option but instead a bunch of 1.3 cables. Im down with 1.3 where its cheaper but I also like the idea of the 2.0 having log to SD standalone function)

Id like to get my cable and wideband setup ordered today if I can get my head clear as to what road is best to take at this point.

Sorry for the lengthy post, and thanks in advance for any helpful information or a point in the proper direction... Im not sure if this post falls more under the tuning section of the forum but most of these questions seem rather noobish

ha really no one has anything to say on this one?

its almost confusing, i would call the manufacturers of plx, aem, innovative to help, since you want those widebands.

While I can't do much to help your wideband question, I can clear up your cable confusion.

If you plan to use Ecuflash/Evoscan to reflash your stock 98 ECU you MUST use a Openport 2.0 cable. You can use the 1.3 cable to datalog, but it is not able to flash our ECU. The Evos are free to use the 1.3 cable for flashing, but we cannot; it has something to do with an input voltage that our ECU's require to be flashed, the 2.0 cable can do it, the 1.3 can't.

For logging a wideband you can follow this guide: Wideband Install it's on an EvoX forum and it's not perfect, but the concept is the same. You are free to use a compatible serial to usb adapter, and Evoscan is slick enough to pull data from both ports.

As for using a wideband in place of the stock O2, I had heard that you can run the LC-1 in place of your stock O2, not sure how much truth is behind that though. I also am interested in the concept, hopefully somebody can chime in on it. Hope that helps you out.

Thanks for the help man, I talked to a guy at aem and a guy at plx devices and they both said running the o2 in the stock rear location is a pretty good spot to run it if you dont want to weld in a new bung somewhere... as long as your running a test pipe and Im pretty sure I read somewhere you can flash the ecu to no longer check for the rear stock o2?

So im thinking of running that. I went ahead with an AEM UEGO set up tho I did manage to figure out after I had ordered it that the LC-1 actually can plug directly into the op 2.0 cable and log via that... at least directly to sd card... im not sure if anyones got it working WITH evoscan that way or not...

but making that serial cable connector for the AEM doesnt seem too too difficult and I like the gauge style better. I think itll be easier to notice if it moves to much either way
