Has anybody hooked up a VDO tach to their F7? If so, we are looking at hooking one up but have a couple of questions.

1. Which wire did you tap into?

2. Did you disconnect the stock tach/speedometer?

3. Did you test the voltage or experience any problems with the tach hooked up (more voltage puts computer into "rich" mode, over 14.2)?

From what we have been told, the voltage should read between 12.5 and 14.2 at 3000 RPM's. When we do this, we get between 11-12 at idle, and only about 9.5 at 3000 RPM's. Seems run ok, but are worried about hooking up tach with this low of voltage. Any info would be appreciated.

Thanks.
