I have a VDO Xtreme tach hooked up to my s/c 2006 apex , it turns on functions & recalls runs. The problem is it reads off -50%(ie @ idle it reads 600 rpm & wot 6500rpm) I have the signal connection for the tach going to #1 coil pack.I know people have moved away from theses & went to pro loggers etc but i would like to get this to work . Any help appreciated Thanks.
