Only the 460 since they share the 8 speed AA80E tranny with the ISF. The connectors are identical. ISF module on the right in the pic.

They occasionally have them on eBay. Also on the GS460 facebook group, which is where I found mine. I believe someone is currently selling one, so check. Worse come to worse, you can find them on copart near you and then exfiltrate it yourself 🥷.. (jk)

플러그인 플러그로 바로 활성화될까요?

Simply plug and play, the car does the rest. Post pics of your 460!

It wont, unfortunately this is a big misconception of this mod.The SPDS logic (rev match downshift, and lockout) is in the ecu, not the tcu.

The biggest difference is the shift speed when in "manual mode" using the ISF tcu.
