Exactly. So pretty much the OBDII solution is not feasible, thus bringing us back to point one with getting a sensor directly into the transmission pan.

Well I think the question hasn't been verified that ODB2 doesn't give the info. I've got an ODB2 reader, but manual trannys typically don't have temp sensors like autos do.... I'd need to plug my autoenginuity into an auto to test.

Very good Kris. Is it possible to run the car through a BMW diagnostic system to give such info? As compared to say a module that runs through the OBDII port? Meaning that the BMW direct system gives ALL parameters that can possibly be given as compared to the OBD tool that was on page one that can miss certain readings.

Well as of sometime in MY2000, even the BMW diagnostic systems plug into the ODB2 port.. they just speak an 'enhanced' protocol.


The newer Autoenginuity with the enhanced protocol compatibility can see it:

..but it looks like it's not included in standard ODB2. Bummer.

Hmm, must have gotten mixed up. I was sure that you had written about having a ScanGauge installed under your rear view mirror.

Nope, not I.

He does have his radar detector there though.

AHA! I was sure there would be some geeky gizmo under there...

I saw a video of him starting his car up, sounds like a spaceship start up sequence.

All this OBD2 talk is making my head hurt. Mechanical gauges have SIGNIFICANT advantages in a project like this. Mainly, it either works, or it doesn't. But also, easy install, faster, cheaper, and simple. In the time you spent to make this thread, you could have ordered the parts and been almost ready to install.

ODB2 gauges either work or they don't as well .

Yes, but since they are electric, usually with a sender unit, you have multiple points of failure.

Well yes, but your car already has it built-in, and input from the sensor is probably used for something. If it detects the temp >xº, you probably get a transmission fault light and it'd go into limp mode. In other words, if any of the points fail, you'd have more problems than just a gauge not reading correctly. With a gauge, however, you could maybe see why you're getting a fault code.

To purely see temp, drilling would be the best way, but tapping into sensors that the car already uses for input can provide you more valuable information IMO.

I agree. But I also am a little "old school" because all of my race cars had MECHANICAL gauges because I believe them to be more accurate with less room for failure. In a computer controlled monster like the E46, it probably would make sense to tap into the OBD.

SLIM, if you do this, send me the DIY......

Mechanical gauges are certainly very reliable, but I would rather run wires than fluid-filled tubing into the cabin. Just my personal preference.

Agreed. If you have the time and willingness to drill and tap for a sensor, or to take advantage of an existing threaded port for a sensor, that's fine, but I'm more interested in the minimally invasive ways to get data.

Also found these vendors while browsing...the side-by-side product comparisons on the DashDAQ site are interesting, for what they are worth.

Nice... you're a clueless noob and you have the nerve/balls to call a mod (who knows his stuff) an a$$hole.

Grow up.

Don't care how old he is. He needs to learn to throttle his pie hole and respect authority/mods.

At 16, had I made some of these comments, my old man would have a boot up my arse. And rightly so.
