the up and down readings is for open loop and the best way to tune your low settings is to get a pocket logger or some kind of scan tool and tune by short term fuel trim readings. 80%+ throttle starts reading off a fuel map and will stay at a certain AF ratio. this closed loop mode is where you'll need accurate O2 readings.

(or did i get open loop and closed loop mixed up? i always get them confused with each other)

 

not to sound like an idiot,how much for a wide band o2 and where
can one be had??

 

I turn on the laptop, open AEMPro v1.03, open a parameter for IDC and pc log.

I don't know of another way to do it.

The AEM UEGO still strikes me as the best/most affordable option. It's between $350-$400 generally speaking.

EDIT: The downside of the AEM UEGO is that it doesn't come with a display. You SHOULD be able to tap the simulated 1v in order to hook up a standard gauge, but I don't know if the output will be just like if you had a narrowband sensor, or if it will accurately represent the O2 values that that 5v picks up.

 

yeah, but what sucks is that you gotta have a standalone to use with it. more $$$ you gotta be a to have the whole setup.

what i don't know about it is that there's the $700 one that has both a 5v and 1v output and whether or not you can use that 1v output to a stock ecu.

sucks about idc readings

 

All the UEGO's have both outputs.

You don't have to be a pimp, you have to set your goals and then pay for them.

 

setting goals is the most important part of tuning a car. Without them, you'd just buy whatever and slap it on. Currently, I'm more concerned with braking and turning on my car before I slap more power onto it. Springs then 300ZX brakes are my next upgrades for the 240SX, then I'll focus on a new turbo setup (hopefully with an external wastegate this time) and tuning that setup. Sorry to get OT on that

 

I'll ***** slap some topic into you, Bart.

But yes, I agree. Anyway, back on topic.

 

haha, what is the topic? seems as if Boni got his gauge hooked up. and now we're on widebands. does this mean this thread is gonna get closed?

i've seen a single channel uego go for $480 while the dual channel is about $730(retail). i was always under the impression that the single channel didn't have the 0-1v connection. thats kinda why i asked. i remember reading the difference somewhere but i couldn't find it on the aem site right now.

since i'm not going turbo anytime soon, i'm just gonna get a pocket logger and get my tuning done that way. cost effective and less chance of tuning with my mods.

quick tidbit on braking. Bahamut asked me to share this cost effective way of upgrading your brakes.

my big brake upgrade is much simpler than that. Z32 calipers (300ZX) will bolt right onto my spindles and a Z32 master cylinder bolts right in place of my stock one.

Andrew, it's gonna take a lot of ***** slapping to get me on topic. I'm a member of the C.L.I.T. Hijacking is too second nature now, but I'm trying this whole world of posting on topic Now I digress back ont othe subject of wideband

 

There's also lambdaboy and the innovatemotorsports wideband w/datalogging and all the good stuff you'd want (about $350)

 

do you know any dealers that carry those?

 

The only ones I'm remotely familiar with are FJO and Tech Edge. As with ANY WBO2, make SURE you can find replacement sensors. They have relatively long lives (AEM uses a Bosch sensor that's supposed to be good for 60,000), but if there is a problem or failure, you don't want to pay another $300 just for a sensor.

EDIT: And Bart, I've been an established hijacker since before you registered. Now I'm on the side of the law.

 

yea AFR Gauges are retarded, i wish i never bought mine, at any rate some guy tried to charge me the price of a sensor to tune my car with his WB02, checked the price of the sensor and it was like 279$ lol.. i just went out and bought my own WB02

 

the only time your a/f guage is accurate is when you are at WOT!

 

The only reason why it might be accurate is because your car is dumping as much gas as it can into the cylinders, so the O2 sensor is constantly at 1V, and the guage will read that as full rich.
