Speed gauge adjustment

[Boost]

I just recently picket up a 2nd hand m3 cockpit, my old 318is cockpit didn't function very well anymore.
I have installed the cockpit without too much problems.
Only 2 things... When im going 50 (km p/h) i actually drive around 35 km
also the rpms seem to be off.
When im revving at 3000 rpms on the counter sounds like i do 5000 rpm's
Is there a way to adjust these settings or do i have to look for a new 318is cockpit?
Thanks in advance

I think warned you not get the m3 one in your other thread because this would happen. The gearing in the speedo is different now so as far as I know there isn't anyway to adjust it.

The dials should be able to take adjustment.

When you size your wheels up, the odom and tach have to be altered..... so it must be possible.

the dials are computer controlled, the gas guage, the tach, the spedo, are all digitally controlled, so there is no speed cable that plugs into the back of it... the reader for the spedo picks it up in a dif. part of the car and sends the signal to the guages

Well, I know you warned me, but i got the m3 one 2nd hand for 20 euro, that should be around 30 dollar (for this price it was worth the gamble)
Well, if I can't get it adjusted i'll just check up the old one or buy a "new" one
Oh and for the record, i'm not one of those persons who is going to put m3 badges all over his car when it's not actually an m3 (the cockpit is the only thing m in my car right now)

don't worry, not afraid you will.
