Also, how do you adjust the speed reading on the OBC? My speedo is pretty good (I was in convoy with 3 other cars - a stock e36, a modified e46 and a stock e30 plus my modded e30 all with CB radios) and all our speedos were the same. My OBC reading was about 10km/h slow.

Any way to change it?

[gearheadE30]

I don't think that you can change the speed reading. Most BMW speedos tend to be about 5 mph off, which is roughly 10 kmh.

BTW where can I get the code plug to update my 6-button OBC to the 13 button? All I know is that I need the green plug from a car originally equpped with the 13-button. My car also had the exterior temp sensor ripped out by a wayward pothole. Does this plug into the back of the OBC as well?

[echothreezero]

The green plug is on the back of the IC.

As far as my speed query goes, we belive that the speedos are pretty good and the OBC is out. Funny that considering it gets the signal from the back of the IC.

not ususally, dude, ALWAYS. it ALWAYS starts working again.

The OBC in my euro car changes minutes every like 30 or so seconds. its completely fucked. the backlight burns out about three days after i replace it too, so i just stopped caring.

Haha, mine does that, I just punch it and it goes right back to not working properly.

how in the hell do you set the clock in a 13 button?

call me stupid, but this damn car with no cup holder has gotten the best of me!

[CarsSuck]

its easy. Set the display to time. Use an ink pen or similar prodding tool to push the tiny recessed button and then the number buttons at the bottom to change the digits.

Thank you.
