Some specific Robtune 550 questions

Post by nortonjefferson » Sat Dec 05, 2015 2:01 am

So a little more than a week ago i bought an ej22t with dohc ej25 heads, intake manifold, 22t exhaust manifold and stock uppipe and everything all plumbed to run boost (it was pulled a strong running motor) and has 40k on the build. I plan to put this into my 93 L wagon.
I saw a post by Rob saying he has a tune specific for this motor build, can anyone confirm with me if this is true? Also referring to buying my supporting mods i bought a vortech 7:1 fmu, would this work with the robtune? I have a Walbro 255 on my car, 550cc injectors coming my way, a Grimmspeed MBC, the vortech FMU (if it works??), td04, 02 wrx tmic, and a few other misc goodies i cant think of off the top of my head. I still need quite a bit more of the components required for the swap but im getting there.
My next question is the ej20 ecu used in the robtune compatible (i say that lightly) with my non-turbo car? Most threads ive seen people are putting the ecu in an already turbo car, does it matter? Im relatively new to turbos and the like, i have read a majority of the robtune threads and these were some of the questions that sprang up in my mind. If anyone has any of these answers i would be beyond thankful. Im sure i will have more in the near future. Thankyou for your time!

EDIT: i found a few n/a to turbo robtune threads, perhaps Turbo Wagon can chime in on the things required?

Email Rob, I think there's stuff about the wiring harness that's different, but idk. I started with a turbo car.
