Hello,

I have problem with audi digital tacho (green, used in urquattro and some other models). With vems 3.3 motr55 plug'n play unit tacho works as should, but if I use vems 3.3 (1.1.88) with ec36 and ec18 pinouts tachometer dosen't work. In vemstune it works. Tacho signal is from EC36/04 and and in vemstune tacho is set to the same pinout. Cable between vems and tacho is ok.

Any ideas what seems to be the problem?
