I don't know much about n/a GD specific applications but I do know a bit about the helmholtz resonator. How did the GD guys get around this? Did it have negative effects on the MAF readings? What about power? Any loss in power?I would be worried about the effects of eliminating the Helmholtz resonator. It's been shown that on N/A GDs eliminating the resonator can cause really bad oscillations around the MAF and cause fueling issues.
ALso, would AEM plan to retain the pipe to the cabin, or close that off? Not sure which way I'd want to go with that yet...
The "Hybrid Intake" was put together. It was a smooth intake tube that connected to the stock airbox and the "milk jug" in the fender.I don't know much about n/a GD specific applications but I do know a bit about the helmholtz resonator.

Don't forget that engine load is determined by MAF readings, not just fueling. So it will efect other functions.So the problem here would be that the car would run really rich. Does the BRZ have a helmholtz resonator?
So what do you think we should do, hold off on a CAI until we can work with the ECU?The "Hybrid Intake" was put together. It was a smooth intake tube that connected to the stock airbox and the "milk jug" in the fender.
Here's a write-up on the whole deal: http://forums.nasioc.com/forums/showthread.php?t=1471819
Apparently TiC found a way to compensate with the ECU, but it will likely be a while before the BRZ ECU is cracked.
Thats what I figured could be a resolution. Its the oscillations and resonance that is causing the misread. If they could avoid it, problem solved?I think it's a matter of letting the good intake companies do their thing to bring a well-developed product to market and then choose. Jumping on the first tube-shaped intake with a cone filter is not the way to go. So let AEM and K&N, etc do their thing.
THEN, let someone be the guinea pig and see how the MAF and fuel trims like the new intake. Hopefully someone near by will have a BRZ and buy an intake so my friend can log the car and see what the results are.
As an arm-chair engineer (so take this with a grain of salt) I think that if AEM and the like retain the acoustic pipe at the same angle off the pipe, it will lessen or eliminate the resonance around the MAF as the energy from the oscillations will be absorbed by the "speaker" in the cabin. But again, that's just my uneducated assumption.
Will do...I was talking to ken...by the way really cool guy...he was telling me on the time frame they might need the car for...but I'm not worried cause AEM has been in the car industry business for some time now...so they know what there doingNice! Let us know how everything goes. Remember to mention those MAF issues we've been discussing.
