rev counter not working since ecu swap

[tango123]

Since fitting a maxxecu the rev counter has stopped working. The settings in the ecu have been changed but it hasn't made any difference. It should just work p&p as far as i know.
Any ideas??

cheers

Does your tacho settings look like this?
And are you using GPO 8 as output?

Might not be the ECU sometimes mine stops working a thump on top of the dash gets it going till I sort out the connections.

Strange, that should work.
