Hi Andre,

I have worked with some DI cars (Ford Ecoboost, Honda Type R, Mazda MX-5, Subaru WRX DIT) so far but have never changed "Injector phase" or "Injection angle". I just read some articles about that changing these tables could also make some extra power. So since there is not any video or explanation about it I wanted to ask how is the best way to start moving these tables and test them.

The only car I have moved this table is on the Mazda MX-5 ND generation because of rough idling after supercharged is installed and because EcuTek recommended me to smooth it. Honestly, I didn't see any improvement.

Thanks.

Hi Victor, while we haven't dealt with DI injection timing inside the courses, we have covered this in a webinar. You can check it out here: https://www.hpacademy.com/previous-webinars/157-understanding-direct-injector-di-timing/
