started working with alloy oilpan. needs to be chopped a lot, over half off from height and corners cut above steering rack. if anyone has us spec ac at blue blue , blue yellow stock front springs i could buy them. mine has some sag on these

I'm installing this kit in my Z right now, and that explanation for the RPM wire doesn't make sense to me. The White wire that connects to an IGN hot source should serve that purpose, and I bench tested mine with a DC power supply that provides a current draw reading and sure enough, current draw goes to zero when the White wire is disconnected from power. I have seen that some EPAS ECUs require an RPM signal to enable the system so that it's not active when the ignition is on but the engine is off. That way, you can't put a potentially big electrical load on the system when the engine isn't running. However, that doesn't seem to be the case with the Silvermine ECU. The system is enabled and active as soon the White wire is powered. Perhaps the ECU manufacturer disabled that RPM function but left the RPM input wire for whatever reason. A friend of mine suggested that the RPM input may be a backup of sorts if the speed input is lost, but I tested that and RPM doesn't appear to have any effect on steering effort when there's no speed input. Has anyone found a conclusive explanation for the function of the RPM wire on this system? I'd prefer to avoid connecting wires that I don't have to. Nigel
