Hi All,
I've searched around and cannot find an answer. Bit of a stupid question but I am very interested as to why a crackle map wont work on the 2016 AUDM BRZ.
The car is turbo and has no cats, and just 2 mufflers. It pops very loud on occasion, so I assume a crackle map is possible.
However, I have not been able to get a crackle map working. Usually I pull -10 or -15 degrees from the low engine load regions in the base ignition timing map, I've attached a screenshot if it helps.

This is what everyone online usually does as it's basic and simple, but it seems as if the car is fighting the requested -10 timing. I can see in the logs the car just returns back to 35 degrees timing when feathering the throttle.
I also tried changing the target AFR to 9.5 and base timing to -15 with the RACERom custom maps. But again the timing does not retard or change from 35 degrees and the target afr stays the same. It's as if the car has built in protection to stop the user from doing stupid things.
I attached a log screenshot to show my attempt with 2 custom maps M and N. You can see M is requesting an AFR target of 9.5 and N is requesting -15 degrees of base timing. But nothing actually changes.

I am just wondering if any one has been able to get this working? Also now interested as to why the ECU is doing this.
Thanks,
Chris.
