Traction control pins

[dailey]

Anyone know how to hook up the traction control throttle servo?
i want to set it up so i can limit the power, if i ever let someone else drive the car. a sort of valet mode.

why not by an aftermarket rev limiter and hide it under dash and select 3000 rpm when u give it to someone

much easier than trying to get trc to work

Because the t/c servo is there.
i reckon it would only need a pot or switch to get it to work.
i just need to know what voltages etc the motor needs.

And i might add t/c later.

had a bit of a play around with the tc servo. Its just a basic stepper motor.
i should be able to put together a simple circuit to get it to work.

i guess u dont know whats involved with t/c
there is 2 computers whioch talk to each other

one is abs

other is abs/trc

massive job to fit t/c and get it working properly on a 1uz

anyway the trac motor has 6 wires
prob works similar to an idle motor but im pretty sure it has gears inside it

and there is a throttle sensor which sends signal to the trac ecu telling it where the butterfly is

this will be your problem

another way would be to just make a device to close the trac butterfly fully closed but drill a 10mm or 15mm hole in the butterfly so when fully closed
all the air goes thru this hole and its the max air flow u wil get

trying to get the motor to half close the butterfly might be harder than u think

so getting to close fully would be easier i guess

but i recon there are easier ways to do what u want than playing with the trac motor

u would hate for the unit to fail whiloe coming out of a corner really fast cause a car is going to hit u heheh

fly by wire and trac control in my opinion is not somehting to be messed with

i do set-up and programme industrial automation stuff at work.
a basic t/c setup wouldn't be particularly hard to do.
there are heaps of circuit designs in the internet for driving a stepper motor from a pulse input, and most aftermarket ecu's have a PWM output.
I might also use the tc motor for rev limiting, mush more engine friendly than fuel or ignition cut.
