Stock BRZ turbo map

Hey Andre- quoting you on a previous post:

I know that originally BRZedit didn't give you a complete definition which limited what you could do with a FI application but I'll assume this is fixed now. Obviously you need to rescale your maps so that they read into positive pressure as a start. You'll also need to have the ability to raise the stock load limit so that the ECU will read into positive pressure. There are a couple of different places where you need to do this but I'm unsure if BRZEdit follow EcuTek's naming conventions. There is also a function called 'Port Injector Manifold Relative Pressure Comp' that you need to modify. This is normally set to 1.00 in the positive boost areas and will cause the engine to go lean as boost increases. A linear increase in the multiplier as you move into boost will fix that.

Is this the map you're talking about?

I have made the changes here to compensate for up to 2 bar (looking to run only 0.7bar boost), not sure if the smoothing is enough?

Also, would my ignition timing be conservative enough on a g25-550 on 10psi wastegate pressure? (On NZ NPD100), and will scaling of up to 2.3g/rev on engine load be adequate for this boost level?

Thanks in advanced

Anyone? 😂

I can only give you advices no real facts, since I just started my BRZ Turbo build with the HKS GTIII-RS. As always your best bet is to take a safe and educated approach. Calculate engine load according to expected airmass on this load. Based on that you can extend your maps and rescale. This won’t be accurate enough because VE of the engine is not always the same. Log your engine load and see when it maxes out. Timing doesn’t look to bad, make sure you have the knock strategy in place and most important make sure you don’t run to lean during WOT. My approach will be having a boost gauge and Wideband wired as first thing to monitor correct lambda. Also would make sense to have an EGT probe installed to make sure you have solid temps. As soon as I will advance with my build I can share my findings here. Make sure you log as much as possible and advance in small steps.

Yes that looks to be the map he's referring to.

Scaling out beyond the calc load you'll need to ensure if load gets higher than expected, you operate at conservative values, would be prudent, rather than trying to calculate exact peak value ahead of time. You can leave the single highest column as a catchall until you know what peak load will be. For example let's say 5 g/rev. The ECU will interpolate.
