I got my wideband connected to a 12v source and I read the AFR values throught Zeitronix's software. My only problem is that I need to connect the RPM line to the ECU and the outputs to Uberdata. The Uberdata forums are down and I cannot find the information I need to connect them to the ECU. (i.e. the specific wires on the ECU)
Any help is greatly appreciated.

i would imagine u could hook it up to the tach wire that comes right off the distributor. well if you pull out your gauge cluster its the solid blue wire

I just researched this. You want go to go here. http://plxdevices.com/ECUDatabase/Ho..._INT_92_95.pdf

You want the A21 pin for OBDI or the A20 for OBDII yellow/green

What do I connect the narrowband sim. and other outputs to?

Read the diagram. You hook the narrow band sim to the Primary O2 line in you car. The others you cant hook up without the add on items like EGT or Boost sensor.

Oops, sorry. So I assume when I'm done using Uberdata with my wideband I just disconnect the Wideband analog output signal with the narrowband simulated one. BTW, I remember seeing your thread on the Uberdata forums about the innacurracies of the Uberdata software with the ZT-2 kit. Has anyone figured this out yet? If so I'd love to get ahold of that script since I'm ready to tune.

Bigwig messed with it, but it still is not perfect. So, I would just use the ZT2 software.

Well I re-enabled my heater circuit and closed loop with the narrowband sim. wire connected to the primary o2 sensor wire and I got a CEL. I haven't had to time to check it (will tomorrow) and I am wondering what I did wrong. I wired he 02 sensor ground wire from the wideband to a power ground on the ECU. I wried up TPS, RPM, 12v power, and its ground. Any help is greatly appreciated.

You have to cut the O2 wire completely and connect it. Not splice in.
