Re: A couple of questions about O2 sensors

From what I gather, I just need to get far enough back to keep it from getting too hot, about 10mm. The gasses in there are pretty turbulent, so it sounds like there should be no problem for it to get a valid reading.

Re: A couple of questions about O2 sensors

Thanks, that leads to a lot of information. It sort of looks like I could almost pull this off. It seems to say that I could put either type of sensor (wide or narow band) in the manifold, if I can make the bung long enough to get the sensor element back out of the exhaust gas stream a bit. It looks ...

Re: A couple of questions about O2 sensors

Sorry I haven't been on recently. I had a furball at work coupled with a hard drive crash that ended up losing my bookmarks. Then there was the annual knife fight with the I.R.S.

I had an idea in the middle of the night a few weks ago: Is it possible to weld/braze a bung onto the exhaust manifold ...

Re: A couple of questions about O2 sensors

My problem is that it's virtually impossible to get an O2 sensor in front of the cats; The cats ARE the exhaust manifolds :? The manufacturer only perpetrated this for 2 years; the heat under the hood is REALLY rough on wiring. At 35+ years old, I'm not sure how much catalysing they're doing anymore ...

Re: Cold Start Injector

Thanks, I'm just beginning here, so I don't have the "feel" for what info is where. Again, sincere apologies.

It looks like the CSI isn't really needed, the function is taken care of elsewhere.

This looks like it could be a fun project. I hope I can get enough experience to pay back for all the ...

Cold Start Injector

Sincere apologies if this has been covered before, but what I could find with a search didn't answer my question.

I'm installing a MegaSquirt into a Mercedes 450SL, with a Bosch D-Jetronic ignition system. It sort of seems like an ancestor to the MegaSquirt. TheBosch system has an extra injector ...

A couple of questions about O2 sensors

Please forgive me if this has already been covered, but i couldn't find it by searching.

I'm in the "Engineering" phase of a Megasquirt install; that is, I've decided to do it, and am assembling the pieces and parts.

My plan is to build a MS1 v2.2 to install onto a '75 Mercedes 450SL. I plan on ...
