What controls OP/CL switchover in MY04 WRX?
Hey guys,
Im debating whether to get an up-pipe or not with MY04 wrx, and was wondering what exactly controls the open look/closed loop switchover? I heard that it was the EGT sensor, and therefore would be stupid to remove the up-pipe, but I'm not sure about it. Tell me what you guys think, Oleg

My understanding it is more of a fixed time delay between WOT and the switchover.

That's what I've been thinking as well. Do any of the engine management units remove that timing delay?

I know Cobb does on the later '04 maps.

TPS is the trigger for CL=>OP boost switch-over.
