from what i gather the system is sensitive to resistance so a good earth with low resistance is best. i believe it even says to use the block as an earth in the instructions.
i soldered all mine togther then ran a new earth from the battery which i checked with my multimeter and had very low resistance on it and soldered that to the others the guy from ggr who says he fits them all the time said to earth it to wear the ecu earths!
