I know a few people in here have disable the yaw sensor on their 1st or 2nd generation Caymans to disable the PSM. Not sure of anyone in 99x types.


I am wondering if PSM in both gen 1 and gen 2 9xx is tied to the alphabet soup of acronyms including preloading of ABS or only in gen 2?

ABS
MSR (engine drag torque control)
ABD (Automatic Brake Differential)
ASR (Anti-Slip Regulation)

Also wondering if disabling the PSM disables all the above?

Here is some good info on the system:
https://caymanregister.org/showpost....5&postcount=27

"If the Yaw sensor fails [kill switch], PSM will permanently shut down DVC, while leaving the other subsystems working. If however the yaw sensor and one rear wheel speed sensor were to fail simultaneously, then the system would shut down DVC, ABS, ABD, ASC and EDTC leaving only EBD still working."

Just don't disable it half way through T10

The link only brings me to the landing page of Cayman register. I guess I do not have the secret hand shake.
