Post subject:  Re-Calibrating GS Rev Counter

After a test a few days ago, we found (well we always knew) that our rev counter is way out on the race car, we have fitted a rev counter out of a GS which came with the race car when I brought it, anyone know how to check/re-calibrate or even better who re-calibrates them?

Or shall I not bother and bite the bullet and buy a new one! anyone recommend one, the only trouble with this option is we have a nice dashboard in the car, so would need to find one the same size or slightly bigger - smaller would look sh**e!

thanks

Simon

Simon and Sean
postage from the USA seems to have gone up a heck of a lot in the last few years, as some of the vendors are asking over $40 to post a tachometer to the UK... :?

Wonder if this alternative brand would be do the job, even if its red line is on the high side for a 602 motor?

The R1100 & 1150 tachos take their signal from the ECU, I don't know if they'd work correctly if wired directly to a coil. Older BMWs, R100 & R80, are different and might work.

Pity,
that's technology for you, more like tying you into 'dealer servicing only'. :roll:
