	How to mod golf 4 "020" can cluster to understand analog rpm signal « on: June 05, 2017, 10:25:51 AM »

Hi.
I try to find it but no succes.
I put standalone ecu in golf 4 agu.
I see that there is rpm signal wire between ecu and cluster.
Ecu sends 10-12v 50% pwm analog signal.
But cluster wont use it...
I think it communicate via w bus or k line?
I think older 919 use anolog signal.
Is there any way to mod my 920 cluster to read that "normal" rpm signal?
