Anyone using Defi display and syvecs ecu
 

Just had syvecs fitted and mapped on my hawkeye that already had defi's.. my queiry is that if the Defi speed signal wire is connected to the dash the tacho doesn't work on the dash.. and if the Defi speed signal wire isn't connected the tacho on the dash works but obviously doesn't show the speed on the Defi display...

Has anyone had a similar issue or have any idea ?

Thanks in advance

I believe wiring is correct but don't understand why it won't work.. maybe something to do with pull up resistors maybe ?
