been making improvements to the map. changed some fueling tables to make it richer and dump some more fuel. im checking the injector time and on decel its only at about 1.2ms on the DI. got rid of the overrun settings because i think they were more placebo effect and didnt really do anything. also changed the .20 g/rev column to 0 to make the transition smoother. getting a gopro mount so driving vids soon

Andrew, This looks good.
Can you be more specific on the changes you made compared to a clean ROM?

Thank you.

Are you guys flashing the ECU with the OFT?

it seems to pop a lot more, and louder too, with the BPB installed

So base timing A has no changes from an original file? Just changes in B?

invaliduser · 05-05-2014, 09:52 AM

Yes, No changed to Base A.
I'm assuming we still don't have real overrun yet with those settings.

Andrew, in your video, on decel, are you giving a tad of throttle on decel to force the extra fuel?

andrew5826 · 05-10-2014, 03:45 PM

base A table is apparently for failsafe/limp mode. yes still no pops on full decel. need to squeeze the throttle at the right spot

Incorrect. It is the delta between current and past engine speed. By setting it high in the BRZs, it effectively disables overrun - I assume this has to do with the direct injection. So 6000, or 4500 will have no impact - you will never get that kind of delta going into overrun.

I met @moto-mike yesterday. Real knowledgeable guy. I believe he has the same header on the supercharged BRZ.
