Would have to get it coded with a Techstream but nothing that wont take an hour or so.

Just wondering if the car will have the Sport + mode after the ECU swap.

 

Nope. That is a mechanical piece on the suspension that only the IS350s come with.

 

Someone with a 3IS300 should test out the ECU tune from Orange Virus Tuning to verify their 55-75 HP gain on the detuned 2GR-FSE. Several folks in the 2IS community are happy with the ECU tuning results from OVtuning so the results appear to be legitimate.

Yes that's a given.

Just don't want the car to say it's in Sport+ mode when all the components are missing.

It's something minor but it would bug me.

 

If that were a concern, it seems you could just use an ECU from a non-F Sport 350, which does not have Sport S+.

 

This!
I currently have Orange Virus' base tune for the 3is and it feels good - a lot more peppy!
It even changed my exhaust note slightly to a more deep sound on the lower rpms (which is appreciated as I was suffering from some rasp down low)

Waiting for the flashing cables to get in so that I can datalog and flash updates.
