The OBC simply displays 'stuff' thats occuring. I think of it as a way to keep me occupied on long trips, no more, no less. If it could make the car get better gas mileage, provide sexual favors or cook pizza, I'd be all over it..........

Sexual favors, that would be a OBW (On-Board Whore) LOL

in which case the OBC would go....DING! <condom?> <owners manual> not lock the back doors so you cant get in the back!

Lol !

I remember the technical data on the 525i saying the top (limited) speed is at 205 km/h for Canada. The theoretical top speed without limiter is 220 km/h, but that's on a sedan, and concerns the pre-vanos M50 engine outputing 189hp. Manufacture date 09/92 and on have the Vanos and other quaint updates such as wider mirrors. How much more vanos gives, or Dinan chip...

You can get accurate speed readings with the OBC by entering codes, but you first have to unlock it. Search this forum for OBC Codes. But if you don't have the 16" or 15" wheels mounted, the readings will be off. 17 inches is a bit off spec, nevermind 18 or 19 inches.

It's a fact that the speedos are intentionnaly off by 5-10 percent as per regulations, and off in that they show higher speeds than actual.

Have fun !

Right now, I have 17's but will be upgrading to 18's after I lower it and summer is in full swing.

My speedo was pretty accurate when I went to Washington with a GPS TomTom saying I was doing 150kmh and I was doing 150 on the line with cruise control.

So I can unlock my OBC to give me real-time accurate speeds?
