disable ego correction in ms and it wont freak out.
stock ecu won't care if you disconnect the rear o2, it will just throw a cel

if you mean disconnected sensor in the exhaust, it's not a good diea, but won't explode your sensor in .00003 seconds like some will make it sound

Bad idea, that can ruin the sensor. They need to be powered up when installed.

<p>From what I understand all that powering it does is turn on the heater. It will heat up anyways with exhaust flowing by. according to the manuals I'm wrong.</p>

Thanks, I'll just wait until I can pick up a plug. Not worth risking a sensor just for a weekend joyride.

Seems right. I just read online that leaving an O2 sensor installed, but not powered up, will kill them in short order. I read it on the internet, so dunno. But I don't do that to be safe.

To OP, a local MIDAS where I live has those plugs in stock. Most any exhaust shop will have them. You may be able to get one locally.

If not just weld a small diameter sleeve in and tap it.

I will make a plug. Good excuse to use the lathe and practice single point threading.

You'll kill a wideband sensor if you run the engine with it unpowered. That's stated in the manuals for the innovate and AEM units at any rate.

A NB sensor won't care. Early NB sensors didn't even have built in heaters, they relied on EGTs to get to temp, but the temp a NB sensor is, isn't critical to its operation like it is with a WB.

You should buy one. You can get good deal on China ones. Or find shop auctions.

I paid $359 for mine (homier Speedway, same as all the other brands) about 10 years ago. It's been a productive hobby ever since. They go for around $500 nowadays, if you find them on sale. But be forewarned, they are a work in progress. You have to make or buy parts for them (i.e. tailstock lock) to make them useful.

I made my shift **** (out of a trailer hitch ball, no less), and have made several for other people. That's one reason I offered to fix G's, as I already have the arbor.

Benchtop, Chinese made. 7x12 size. Small stuff.

Harbor Freight sells them. They cost about $600 when not on sale, but you can find coupons. They are typical Chinese quality. More of a kit than a working lathe.

thats about what any 7x12 goes for. for about $1k, you can have a 10x22 that is a working lathe.

theyve gone up in price since ive bought, i paid $950 shipped about 5 years ago

Please, go on, I would like to subscribe to your news letter. Seriously, a recent acquisition of mine makes this threads current off topic diversion of particular interest to me.

I have two lathes. One for metal/plastic, and one for woodworking (mostly pens). I made a cigar holder last night because I was sick of spitting out little bits of tobacco. Took me about 40 minutes, all told, because I am fussy.

Shall I up the ante with my mill as well?

I can just envision a lot of small parts and brackets that are a bitch to make/need a welder that would be fabulous to have a lathe for. Also 3D printers.

Plus I just think them & CNC machines are so damn cool(my YouTube watched history is full of lathe/CNC clips)

I always thought they went for thousands though, hence never approaching the possibility of owning one unless I got lucky on a used machine.

Getting a hitch and a tow dolly for my TDI are priority #1 at the moment though. It was 116° yesterday. ****. That. I'm not man enough to drive in that heat in the Miata(no AC). Especially with the hood vents pushing oven hot air into the cabin.
