It was finished (not sure on that particular car) on another STi I tuned. That appears to be the same ITB setup on the car I tuned with a Hydra EMS. In the end it was a total waste of time, money, and netted nothing.
Now I've tuned a high power NA Miata with ITBs. With a Hydra we got about 175 whp on unleaded race. Apparently this was some sort of record but what do I know I tuned mostly turbocharged setups in the 600+ range
. You need a really good EMS (with specific configurations for ITBs) and a lot of knowledge to tune the ITBs well.
I know our main focus for the FRS/BRZ is going to be developing the Hydra EMS so that we can turbocharge this engine effectively. Now we may be dropping the compression first and going backwards from there. I definitely want to get the direct injection setup working so we can at least fully tune this engine's variable cam timing, maybe drop our Hydramist system on it, and tune either race gas or E85. I'm just not sure the NA guys are going to drop $2000-2500 on the EMS but I know the turbocharged guys will in a heartbeat.
Thanks,
