Wideband O2 options

Post by **Legacy777** » Tue Jan 10, 2006 1:11 am

I really need to get one, and about the only setup I know of is the Zeitronix Zt-2. The specs on their page and what it can do look pretty nice, as well as the price.

Anyone have any comments about the Zeitronix and or other WB setups out there.

Thanks

Would that setup have a simulated narrowband output?

Simple Digital Systems has a wide band.

They also have a stand alone ecu with a loom to fit the leg turbos.

I have no idea, but i really need to get a wideband. I don't like people bouncing my car off the redline when its on the dyno and i'd rather do it myself.

Overlooked including that I've been using the SDS stuff on the twgn

I've been looking around, and the zeitronix really seems like a really good option. Options look good, and the price is good.

I'll probably see what the nabisco crowd has to say.....but I think I'm leaning towards it.

I haven't researched any of these units, but one thing to find out about each candidate is what type of sensor it uses. These sensors don't last all that long on engines that run as rich as ours tend to, so it's likely that you'll eventually be buying a replacement. Some kits use a sensor that's cheaply available from Volkswagen dealers; others use a sensor that's only available expensively from some retailers. There are a few in between.

The SDS uses the Bosch sensor

There are a few different forms of the Bosch sensor, and different connectors as well.

I bought a zeitronix sensor. Everything I read looked pretty good. I looked at replacement sensors from zeitronix and they want 79 bucks. So it's probable it'd be cheaper elsewhere.

The Bosch used with the SDS wideband is the one that works with the W/B.

The Zeit---- looks V. good

Zeitronix is great...glad you bought one!

That is a nice price.

Let us know how it goes.

I've been running the Zeitronix for a few months now. I'm even using the simulated narrow band output to replace the stock O2. Very happy so far!

Now I'm thinking about buying their boost gauge and running my EGT into it as well, since the Zeitronix can log all of the above.

I mounted the display below the ashtray (on the plastic wall that kinda tilts up towards you ) - a nice inconspicuous location because it's almost hidden by the ashtray, but still in easy view. When I park the car in downtown Baltimore, I just drop a scull cap on the console there and it hides it completely.

I wouldn't mount the display directly in your field of view, because it's bright as crap.

Sam,

Did you have to do anything with the heater output for the O2 sensor. I believe on the newer cars they have to trick the ECU into thinking the heater circuit is still hooked up. I wasn't sure if our cars had a similar type of thing.

Our cars don't.

Nah, I just left those wires disconnected.

Actually, Vikash would like this plug and play approach. To avoid messing with the harness, I just cut the connector off of my old O2 sensor and used that connector to send the narrow band signal into the ECU. I just taped up the two heater wires and left them dangling off the connector. Then, I soldered a long extension wire to the sensor wire that was dangling off the connector... ran that all the way into the cabin to the zeirtonix narrow-band output.

With that setup, you can just disconnect it at any time and it's still plug-and-play with a narrow band if you need to do that.

I do have an electrical noise problem now causes "whirring" through the radio speakers, but I don't think it's because of that connection. I think it's because I powered the Zeitronix box itself off the 12V line for the radio - doh!
