Hey Guys,
I recently installed a Power FC in my Version 4 STi and would love to go about making small adjustments to it for safety and performance reasons.

I think what we get here is about 90 or 92 octane fuel (Some have said 95).

I would love any assistance with a general idea for an ignition and fuel map that would make my car safe and well performing on this grade fuel as this is all we have available.

I know many would say go to a tuner but right now that would mean 'importing' a tuner which is very expensive.

As such I am open to any and all advice.

Thanks in advance!

 

All advice welcome!

 

First of The power FC Base map is set for Jap fuel which will be aggressive even on 98 ron, i would strongley suggest you pull around 6 DEG or more of timing across the map before you even get started due to the fuel you are using, but keep the idle around 17 DEG, however with that said i cant be exact on this as never used a 90 octaine, also the base settings would be closer to that of the U.S cars as they run similar fuel. This also assumes you also have the basic set up ie Detcans, and widband to get you started on monotoring, if you dont then IMHO leave it and save for a Mapper.
