Does anyone know if the OEM gearbox on the SC400 uses a Hall type sensor for the rear wheels? I have just received the reluctor interface for the SM4, and I need to connect it up.

Thanks,

Ryan
 
just connect it to one of the hsi wires
y did u buy the reluctor interface
easrly autronics needed them for toyotas but not the sm4
just wire the crank and cam sig to the relcutor inputs
and the spd wire from dash to a digital input or a high speed input (hsi)
if yr running the auto u need to run orig sc400 ecu so most stuff u just piggyback so all wires u can get at ecu
they are simple to wire

Autronic recommended it, as I am running a built Toyota auto tranny. Here is what they recommended:


ECU side connections;
Red wire to Ignition switch (Pin 1 of SM4),
Yellow to I/P HSI 3 (Pin 39 of SM4),
Green to I/P HSI 2 (Pin 24 of SM4),
Black to Sensor ground (Pin 22 of SM4).

Wheel sensor connections;
Red to sensor +ve,
Black to sensor -ve.
Note which wheel is connected to the input with the tab on the insulation. This is for the green wire output.

As discussed, this all assumes that the gearbox has a Hall type output which should be conneced to I/P HSI 1.
 
Ok so is standard toyota ecu running the auto

And also what r you trying to do

Basically abs wheel sensors are inductive two wire
Rear sensor on gbox that runs speedo is hall effect
There are another two sensors on the auto

Opps
There are two other sensors on auto
InPut shaft sPeed and output shaft speed
They are both inductive
Seems like u want to run auto using autronic
 
No, I am running the auto via a separate stand alone...PCS (Powertrain Control Solutions). I am running e-shift via an OEM Lexus GS wheel as well. That is already programmed into the system. I changed the Power/Snow button to on/off for the e-shift.

The Autronic is only looking for wheel slip and speed to determine high/low tuning set up for traction control.

bout time someone spending money on good ecus
autronics its pretty good and so is the pcs for the auto
where i worked 15 years ago we were the nsw agents for autronic
my car was one of first road cars we did with antilag
was fun

basically i would run the front abs sensor
and rear abs sensor for traction control
maybe thats y they said u need reluctor interface to convert the inductive signal to hall effect
atleast with the abs sensors u have hi amount of pulses so more accurate
its fiddly to get the parameters right for traction control but once u figure it out its good
u always need some slip
just enough to keep motor from bogging down
so u need it to still stay in rev range or torque range but not wheel spin too much

ive been researching the autronic forums cause ive just done an s15 race car with an older sm2 autronic

it has traction control
anti lag
two step rev limit for launch control
two step boost curve
and a motec adl dash
so will be fun getting everything to talk
