Hey All,
Hope someone has the wiring diagram for the ABS module for a R33 GTS-t... I've looked everywhere and also downloaded a few service manuals which all are focused purely on the engine and not the electricals themselves.
I've found a diagram which shows how the ABS unit is connected theoretically but that's quite useless when determining what wire is what.
Finding ABS schematics for GT-R and it's Attesa systems seems to be easy, but from what I've gathered from my visual comparison is that the wiring between the GTS-t and GT-R ABS / Attesa modules are different.
This is the GT-R one, when I visually compared this diagram to the ABS module bolted under the HICAS ECU it's quite different for my GTS-t boat.
Now you're wondering why the heck do I need this wiring schematic? Well... ever seen a modern car launch with minimum slip and no throttle cut? Yes.. they actually retard timing to reduce torque instead of chopping the throttle which cuts everything.
Now, I am planning to connect my front two wheel sensors to my ECU and will be retarding timing based on x % of wheel slip (front vs. rear).. the higher the delta, the more timing is retarded... however not too much retard, because I'll end up with anti lags and bang bang all day instead lol.
I did plan to run the wires directly from the ABS sensor to my circuit (converts sine to square waves) to the ECU.. but that seems a touch messy going into the engine bay.
So yeah, help me do high 10s down the 1/4 with a stock motor RB25
