Anybody have an 18-button MID display in a 4-cylinder?

Based on the sales brochure I don't believe the 18-button MID came with the four-cylinder E36s in the US for my year, 1996, but I'm not sure about other years.

If you have such a combination, please let me know, I'd like to compare some of the coding specs.

Thanks,

What do you need? OBC EINHEIT values?

Yes, to get the mpg correct for a MID from a 6-cylinder into a 4-cylinder. The calibration method apparently doesn't correct enough for that engine difference.

I know the hex/binary codes, and which are the relevant digits, for Check Control and metric/binary readout, but have not been able to discover them for 4 vs. 6 cylinder, or even whether they are codable through those Einheit values through the keypad.

If they are, do you know which binary place the cylinder coding is in and what the codes are?

SOP is to dealer code the OBC with the car's ZCS. I was charged 50 DM (about $30) to show my dealer how to do it. :rolleyes

If you want, I can read out the EINHEIT values left from my coding session. Alternately, you could take your car in and we could compare values.

It would be fabulous if you could get the values -- Einheit 1 and 2, and ideally Test 17 too! I've done a lot of searching on forums and have not found them yet for the 4 cylinder, and tested various promising combinations myself unsuccessfully.

Apart from the dealer no doubt telling me it can't be done, and not letting me watch the coding screens, I'd like to know what the numbers are myself so I can finish off my MID conversion write-up.

I can look up what my values were.

Thanks much for any time to get those,
Marcus
