My vote is aem boost, oil pressure, & wideband AFR. Its what I have You can tell when the oil is up to temp by the pressure gauge. Pressure drops once its at operating temp. You wouldn't be able to tell if it overheated though. And for god sakes please don't use a oil filter sandwich adapter for any oil sensors. I hate those things!
I made the mistake of getting one some time back and needless to say it made its way to the garbage fairly quick. Ended up going with the gallery plug.
You live and you learn.
Boost, oil pressure and oil temp for monitoring your turbo engine's vitals if you're going to track it.
To Adair's point above, replace the 'oil pressure idiot light sensor' with a 3-way combo sensor that has oil pressure + temp + idiot light plug. This is fitted into the top of the block at the top of the oil galley. It's the cleanest installation.
Nope, mine are all the same. There is a light sensor on the gauge for auto-dimming. Maybe its dirty, partially blocked by the gauge face, or not working properly.
What Keith said. My downpipe already had a bung in it. You can also weld one in right after the turbo. A google image search should yeild some good location results. The sensors are kinda expensive so some people only leave it in the pipe during tuning so that it don't wear out as fast. I leave mine in all the time because I like to monitor it.
That's what i was thinking,I will leave mine as well for monitoring purposes. I've seen a few or most of the location for the bung is on the exhaust after cat converter and also that's what it says on the PDF installation instruction that comes with the AEM kit. I know with the AM downpipe, there's alraedy a bung on top it, thisis what confuses me!?!
Im not putting it on the stock DP, that's why I'm asking where would be the best spot? boo-key is the one who attached that pic and i told that's an AM and I still have the stock..(just incase you didn't see the thread)
fuel pressure is a good one to have as well. boost & oil pressure are by far the most important though
