Zeitronix WB, NB simulating, + EVOSCAN
Zeitronix WB, NB simulating, + EVOSCAN
Hi All,
Basically I am looking for a WB sensor. I would like it to be able to be logged through EVOSCAN and I like what Zeitronix has going with their NB simulator. I searched for this info before I posted and found some info, but not all. I found that EvoScan will log off of the Zeitronix WB sensor somehow. First, I was wondering how that works.
Second: Zeitronix has a Narrow band simulator with their controller that you can use to change your closed loop AFR switching point. Click here for more info I was wondering if you can do away with your NB O2 sensor all together, or does this run in parallel to it. If anyone has any light to shed on this subject, I would appreciate it.
Also, If you could recommend any other WB controllers that are EVOSCAN compatible, I would like to hear suggestions. I would also like reasons why you prefer your brand over others.
P.S. Typing: "Innovate FTMFW!!!11ONE!" does not help me to make an educated decision. Thanks, Gregor

Zeitronix logs with Evoscan through a serial cable that comes off of the ZT-2. You just select it before you log.
About the narrow band. I don't think you need it.
Also the Innovate is compatible with Evoscan. I don't know which one I am going to get yet.

i've got a couple zeitronix systems but never tried the narrowband simulator yet. it would be neat to try because you can offset the switching point so that the car tells the ecu its at stoic ratio, but really it runs lean (i.e. better MPG).
my only concern would be the turn on time and sync time so that it doesn't throw a CEL immediately when you turn the car on.

There is no reason first of all to change the switching point and secondly when the wideband starts to get somewhat erratic due to time and wear the car's performance degrades rapidly to the point of nearly not working.
Thanks for the info.
Do either of these come with the O2 bung, or do you have to get it separate? What if I have A stainless DP? And where is the best place to mount it? (as far as keeping it from burning up and keeping it effective at measuring)
I was wondering about the NB simulator because I was thinking of just placing it in my NB bung instead of worrying about welding on a bung to my stainless DP or something. Didn't really care about changing the switching point so much. Although I probably would mess with it a little, just for fun.

unless you are beyond using the cat your only real option is to have a bung welded on. That is easy, a muffler shop can do it for next to nothing. The first o2 sensor location is too close to the head and the sensor will cook. The second sensor location is OK if you don't use the cat.
A spot on the back end of the downpipe is perfect as there is a grommet in the body to accept the wiring, leads up into the console (below the radio). Have them burn the hole between 9 and 3 on the pipe to keep the sensor on the upper side of the pipe.
If you are using a test pipe then you have a bung already.

I have one of the Gallants VR-4s Zt-2 simulated narrowband output running 15.8 AFR in closed loop. The car has a cat and all smog goodies. It's a one happy gas saving car. On the other hand, once you install big cams, you can richup the mixture some by changing the Zt-2 NB switching point and cover that lumpy idle. Works great with stock ECUs relying on the narrwoband O2 feedback for closed loop operation.

mojo,
In order to do the NBO2 simulation with a wideband you need to access the primary O2 sensor from the engine bay. The one on the mid-pipe does you no good.
You will need to disconnect the NBO2 sensor and keep the NBO2 sensor heater wire connected. Then you tap a wire from your ZT2 or LM-1 (that is what I use) and connect the wire to the NBO2 pinout that connects to the ECU.
After that you will need to instruct your LM-1/ZT2 with the new switch points of the NBO2 sensor. I set mine to 15.2. This way you can have better fuel saving.
The best position for a bung if you are running a cat is on the end of the dp 2 inches before the falange passanger side in the 3 o'clock position. If you are not running a cat, then place it in the mid-pipe in place of the secondary NBO2 sensor. But you will get a CEL if you do this.
