O2 sensor question

[MixMasterK]

Thinking about installing an A pillar gauge set with A/F and vacuum gauges. If I switch to the wideband O2 sensor, which sounds like people are having to do, is there any adverse or positive effect to the engine?

Also, what is the part number for the WB sensor?

What gauges seem to work best, most accurate, etc.?

For a non turbo 944, a wide band 02 sensor is a cash flow device, from your pocket to the seller's pocket.

For a turbo, install an extra bung in the cat pipe and plumb in a wideband sensor, but you will need additional hardware to tune the software.

Unless you have tuning capability, don't bother with a WBO2.
If you do, I ran an AEM gauge for a while that worked as intended.

Good advice from the above. It is possible to install a wide band that outputs a narrow band O2 signal for the DME to interpret, this lets you avoid having to weld another bung in the exhaust. Most of the wide band controllers have this feature nowadays. The other option is to weld in another O2 sensor bung somewhere before the cat.

I wouldnt bother doing this on a n/a though. It is handy for setting idle mixture if you think yours is out of whack, but its a literal one time use tool... i would try and borrow one from someone in that case.

AEM and Innovate are the only two brands i would consider.

For my 951 I chose the Innovate system and it helped me diagnose the engine issues I was having. It's mounted on the A pillar with the boost gauge. For an N/A you won't need this devise because the engine isn't as vulnerable to mixture issues as the turbo. It has it's own software and a plug to tie in to software for monitoring the health of the car.

You know, the Porsche 928 has a unique O2 sensor warning system, under the passenger seat they have a box that emits a clicking noise when its time to replace the sensor, the 944 I'm unsure of?

The 944 has no such mechanism.

That said, you can test the oxygen sensor using a VOM and a propane torch. You couild google the various youtube videos on how to do that.
