Idea regarding JAW and DSMlink

[Thor06]

Today I was thinking about what other mods I should do to my Talon this summer as I would like to start parts shopping now. A JAW wideband is on the top part of the list, as is DSMlink. Well, I am still on a ported 1g o2 sensor housing and I am planning on getting a new one. One thing I was trying to figure out is where I should stick the wideband sensor, then I got to thinking. The JAW has two programmable outputs so what if I programmed one to output a 0-1V signal and hooked that up to the stock o2 sensor wires, then put the wideband sensor in the stock o2 bung? Would that work? If you are unsure, would it be worth a shot?

I'd think it would, the wideband sensor would just be doing doublt duty... it would be simulating the narrowband signal for switching between open loop and closed loop and inputting the wideband signal to DSMlink for me to monitor/tune with. Thoughts would be much appreciated!

That is basically what I did with my AEM UEGO WB... BUT I left the OEM O2 sensor in the O2 housing for two reasons:

1) the ECU will throw a CEL if it does not detect a functional heater circuit from the OEM o2 sensor.

2) is is generally a good idea to keep the 5-wire Bosch WB O2 sensor further down the exhaust... Since the AEM UEGO uses the same sensor, I'd go with what AEM recommends: 38"+ from the turbo for longer sensor life.

I ended up welding an an additional SS O2 sensor bung in the part of the downpipe that's after the flex section, right around where the driver's side half-shaft is. It's ~$12 for an extra O2 bung from most vendors... Take that, a #3 Uni-bit, drill, and a welder and it was ready to be bolted back on the car in about 15 minutes

Thats what I needed to know! Good call on the farther downstream placement, I'd be a little peaved if I kept throwing o2 sensors. My 2g friends all have theirs in the downstream o2 spot, since we dont have one I think I'll stick mine where ever is convenient down by where yours is. Thanks man!
