Wanting to learn

[B4 I was 250T]

So whilst I'm not planning to do anything atm I'm on the knowledge path. anyways, enough said. Can The Rev B RSK Legacy B4 ECU be tuned? If not then what do I need to do? Get a link? Or what? Any help, info appreciated. As I said guys, just trying to learn atm. Thnks y'all :-)

Na they can't be tuned, well not easily at least. Hae more of a look around the net, there's people out there who reckon it can be done but costs a fortune. And probably no one in nz who has experience tuning them.

Also as far as my understanding goes a link can't control the sequential turbo system either. It'd work if you changed to the parallel setup but you'd be better off with a single turbo than parallel.

Best thing you can do with these engines is rossubs restrictor pill mod to decrease the turbo switchover impact. or a zerosports sequential controller.

Damn just realised you've already been looking into rossubs mod

Hi if it is an MY01 car onwards then yes the ECU can be reflashed and the car can be tuned so it is det free and the VOD is greatly improved on twin turbo models. Here is one I mapped previously.

The JECS MY99/00 ECUs can be relfashed via Ecutek or alternatively recalibrated via the ECUlabs solution now available:

The earlier pre 99 JECS ECUs can also be remapped via ESL:
