pretty sure its a jzs161 motor. 2jzgte vvti into a 1995 sc300. Ive been told the ecu communicates via BEANS which is a form of CAN bus. I just dont want the car to stall with AC when i push the clutch in.

YES .. use a JDM Supra 2jzGTE VVTi ECU

The solution in which you install a low current relay to get the AC working with an Aristo NON VVTi 2jzGTE ECU is not gonna work on an Aristo VVTi 2jzGTE ECU.

The Aristo NON VVTi 2jzGTE ECU has the A/C request signal pin (pin 34 of 40 pin connector which is the A/C on-off demand pin ) to tell the ECU to trigger the A/C compressor clutch through the ACMG pin (pin 23 of 40 pin connector)

BUT the Aristo VVTI 2jzGTE ECU do not have that A/C request signal pin . They only have the ACMG pin (pin 13 of F59 / B77 Connector ) . The cars that uses that ECU enables the AC through the MPX network .

Your best bet will look for the JDM Supra VVTi 2jzGTE ECU cause it has the A/C request signal pin which is pin 1 of F59 / B77 Connector. You would like the ECU to adjust the idle whenever you turn on and off the AC that is why using the right ECU will be best. You can use a toggle switch too turn on / off ECU but your idle won't automatically adjust.
