We do not have any pre-built tunes for ported engines. You can modify the volumetric efficiency tables to compensate for the porting. You can adjust fuel, timing, oil injection, etc. In my experience, spark timing makes the biggest difference in power. Feel free to download and install the demo version and see what is inside.

Hi Steve,

I was thinking about getting your product because I recently rebuilt and street ported my rotary. Will this product help me? I am currently running stock ECU. Is there a preset within the program that I can select to optimize the port, or would I just need to tinker with it to set all the necessary parameters?

hi can I use versatune In my rx8 09 with turbo?
