Default Seeking info for speedlimit cut on aristo ecu

Ok i got a swap on my 98 gs300, I have a apexi rev speed meter and it incorporates speed limit cut. i followed all the installation on the paper but it does not cut the speed.

I top out at 120mph which is horrible.

Ive done research but im not sure which diagram to go off of.

heres the HKS diagram:


here is the apexi diagram:
this is the old diagram which is for the aristo motor





this is the current one which is for a M/T Supra

I think I remember seeing this somewhere before. I believe the switches are in "SA-3" position. I will try to find it. But, If I don't.... subscribed.

Well, I wouldn't use the HKS diagram as that is for an HKS SLD Type II. I would use the T-10a diagram provided by Apex-i. Silly question, but do you have the speed cut feature turned on? Are all the vehicle settings correct? Is the RSM operating correctly on all other features or are none/some of them not working as well?

@SLVRGS300 on the Apex'i RSM I can see my RPMs, Speed and everything. The speed matches the cluster speedo, but i played with the settings in speed cut and still cant seem to cut the governor. I adjusted the setting as the diagram and cut speeds at 160,170,180.

Well I also have the HKS SLD lying around too, I just found out that the Apexi can cut speed, so I might as well use that. Im like seeing different location of speed wires and they dont match any diagram that are provided.

Nope, but I have MAP-ECU2 sitting in the basement waiting to be installed. It should be able to tale care of boost/fuel/speed cut. We shall see.
