ok guys i need some help. this is for my uncles st165 alltrac US.
He has swaped the engine out for a second gen 3sgte that he ordered from japan (no egr)
He has been running it on the stock st165 ecu whole time. well we just bought a st185 ecu and plan on hooking it up we need the st165 to st185 harness adapter if anyone know where we can buy it? but i wanted to know what kind of gains we were looking at getting from running the st185 ecu instead of the st165US ecu on the second gen engine. because what i have been reading on threads are people running on first gen 3sgte engine with a st185 ecu setup.
