Help needed with speedo and tacho signals

Hi guys, I am asking on the off chance that there may be some expert among you who can answer this question. I have a kit car with a S2 Stack Dash Fitted and am trying to set up the Speedo and Tacho. What signals is the dash expecting to see cos I have tried all sorts with a pulse generator but to no avail. I have notice movement in the dials when i briefly short out the respective pins to earth however no steady movement can be achieved. Any Ideas?

Try over at more monkey http://www.monkeytuner.com/forum/ Charlie who owns the site has a wealth of knowledge on all things S2 ECU dash etc.

By S2 dash, I presume you mean Elise S2 (Rover K series engine), rather than Exige S2 with the Toyota engine? IIRC the latter is not made by Stack.

Mr P is right if it is a K powered one then just ignore me

Yes it is a S2 Elise actually so no canbus issues but still not as straight forward as i wanted it to be. Any help would be greatfully appreciated.
