Ok...so ive been looking up Wideband kits recently and its juss making me more confused

Im looking for a wideband O2 with a gauge and datalogging ability. I looked at a few Innovative ones. LC-1, LM-1, XD-16. I dont care too much about the meter that comes with the LM-1. what do you think of the PLX M-250?

what would you guys recommend for what i want? thanks

 

Gauge is really not necessary. Datalogging is a must. Mine has both and gauge is hardly ever used, just something pretty to look at. Monitoring is useless, datalogging for tuning is priceless.

 

i think a gauge is very usefull cause in case something is wrong you can see if the a/f changed for some reason.
datalogging is the real tunning solution but gauge is good for monitoring just in case.

 

i wanted to have a gauge so i can see whats going on when i drive. maybe its not totally necessary but more for peace of mind.
which wideband are you using?

 

LM-1 all the way.
I use one daily.. briallint.. don't even bother with a Motec of Microtech unit.. waste of money.

 

This is what we call a false sense of security. The gauge will not save you. By the time you see the air fuel is out, you have already melted two pistons. Remember at even 6000rpm you have 100 revolutions per second which is in and around 20-30 combustion sequences. If it takes you one second to see the air fuel is out and let off you have already gone through so many combustion sequences that your screwed. It's proven you simply can't lift fast enough to save the motor.

Again, an air fuel gauge is totally useless even a wideband one. It's sometimes nice to look at going down the track to re-affirm that everything is ok, but really it's only a light show inside the car. Even from a tuning standpoint you can't watch it and make changes, it's just too fast.

 

so you guys say a LM-1 is a good buy? also a question do most of the wideband o2 provide a second output that will feed the stock ecu so only one o2 sensor has to be used?

 

Unless they've increased it, the LM-1 has only like 88 seconds of datalogging on the unit itself which to me isn't very much. That and the huge size of the unit are the turnoffs for me. Oh and the fact that I had the power cable socket completely fall off the circuit board the first day I used it. Luckily I was over at MikeD's house and his uncle is a very experienced solderer because he worked at an electronics/microchip company, so he did some very fine soldering work and got the thing fixed for me.

 

Try ~44 minutes.

 

Hmm wonder where I am remembering that figure from then. Maybe from another wideband.

 

what do u guys think about the Zeitronix Zt-2?

 

Here's an example of a log of the LM-1 with RPM converter. Without the RPM converter, you'll only get AFR vs. time. The RPM converter lets you add up to 6 more things to log.

 

Jime:

Sales of widebands to J&S units is running about 1000:1.

I need to hire you as a PR guy.

 

I have the Zeitronix but if I had to do it again I would get the top of the line PLX. I think its the m-500 or something. I little pricey but nice.

 

what advantage would this "m-500" have over, say, the LM-1?

 

Hmmm I was hoping for a 1/2 price deal.

 

So is buying a WB o2 sorta like personal brand preference? I mean most decent units I see on ebay have datalogging capabilities...so why do some cost more than the other? Accuracy?

I'm in the market for a nice decent one....no LCD/gauges for me, cuz I don't wanna light show and want to save the $100-$150....anybody have any reccomendations?

also how hard is installing a WB? I already got a spare o2 bung in my test pipe...i just put the WB in there, route the wiring through the firewall, then plug everything up and call it a day? or is there more stuff involved? thanks!

 

same question as steven88?

 

BUmpity bump...

I'm most likely going for the Zeitronix ZT-2...a local is selling it for like $250 brand new without the LCD....not too shabby of a price for a WB with datalogging capabilities....Are all of you ZT-2 owners have a ball with this WB? I want to make sure I'm making the right decision before I go out and buy it...

I'm only tuning with the V-AFCII and sticking with bolt ons...and I only need datalogging capabilities for AFR to RPM...no PSI, EGT, LAMBDA or whatever...just plain old AFR to RPM....is the ZT-2 good enough for this task?
