2003 w/2jzGte need Insight

[enash99]

Are there any roms available for an 2003 IS300, or software that will give me some insight into what the stock ecu is doing? I have the Tactrix Open Port 2 cable that i tuned my03 subie with. I am currently tuning a friends haltech F10x on his 2jzGTE. I have just the standard OBD II scanner to read the stock ECU, outside of the Haltechs logs. I would really like to get more granular data logs. The haltech is fine for what it monitors.

Thanks for your input..
