Weird Monaro ECU's?

[Lincsls1]

So what do we reckon these ECU's are about?...

Taken from a 2004 Monaro VXR apparently.
Didn't think our cars were sophisticated enough for stuff like this.

I'm guessing they are from a VE Commodore with magnetic ride control, certainly not from a Monaro anyway.

First one (22235526) doesn't come up in the EPC so I'm guessing it is only used on HSVs. They fitted MRC themselves.

Second one (24413377) comes back as the Sensor Active Brake Control (Yaw) used on 05 to 07 Commodore / Monaro etc.

I've no idea what it does though
