Default N/A tuning w/ aftermarket ECU

Have any of you done this? Especially on a stock EJ22 or EJ25?

I am thinking, that there is a lot more timing and advancement available on the standard engines than anyone (in the Southern Hemisphere) has tried.

My reasoning for this is that my EJ20 is very very capable of topping 210km/h, and that is only with an exhaust & panel filter modification.

I think there is a lot more that can be done tuning wise with the factory setup.

Your constructive opinions and advice would be appreciated, as NASIOC has had more experience with tuning NA than us peeps downunder!

Do you have higher octane fuel available than your car currently needs? If you do, then you can play around alot more with your timing curves.

8 Complex on the board "tuned" his car while it was NA before he put the turbo on it. Hopefully he can chime in, or else PM him (I thinkthat he is the moderator in this forum).

Yep, we have 91, 96 and 98 octane available.
91 is our lowest "economy" fuel.
96 is what most of our WRX's and other turboed cars run on,
and 98 is what a lot of clubsport/motorsport members run.

I currently run 96 as it burns cleaner than 91, I get better mileage and improved throttle response. When I'm feeling rich I'll run a few tanks of 98 and go for blats around the hills.
