Installing AEM O2 sensor

Woohoo! Some time to work with AW11!

This thing has been bugging me for a while. I’ve had everything for this project for ages, but I haven’t found time and willpower to get this done. But now, here it is: AEM O2 sensor.

I already had the car supported on the jacks and this is what I had: a rusty test pipe.

I bought a wire brush wheel to get some of the rust off

I’ve drilled a pilot hole for the cone drill bit

Maladar gives me a hand so I’m free to take pictures

I cleaned all metal shavings as well as I could

Then I wrapped the insulator around the pipe and started to tighten the bolts. AEM is still using imperial fasteners. BTW, the rest of the world is metric!

Everything fits as they should…

I installed the test pipe back to the car and plugged the wire to the gauge. I was lazy and just took the easiest path with the wire

Everything back together

There is enough clearance on both sides, though it looks like the sensor would hit something when things eventually start to move. Swaybar doesnt move much and the distance from the end of the sensor to the trunk bottom is longer than it seems. It’s just shadows playing 🙂

I think we can now start the AEM EMS project 🙂

Great job as always Juha :D! I may have bought some new wheels, expect an email at the end of this week/early next weekish ;] I got to test drive an mx5 turbo my uncle recently bought, holy nutsack batman, that thing is QUICK. It left me feeling a little bit sad about mr2, I fear the cam timing is off 1 tooth afterall, it’s so gutless under 4k RPM, next year is going to be a big year for mister2, I smell a 20v or turbo coming :]!
