Hey guys,

Have a problem with my speedo, it's only reading 1/4 of the speed im actually doing.

Now I have a Greddy EMU that can adjust this feature, but it doesn't affect it when I do. My guess is the speed signal wire isn't properly connected the the ECU in the first place.

Is it a possibility to patch into the signal wire down at the gbox and run a separate wire to the ecu. Then maybe address the situation another day when the engine needs to come out? If so, which wire is it? There is a Red, a Yellow, and a Blue/Red.

Cheers guys
