My car just ran out. I would have done this while it was still in warranty, but now I am waiting to see if a new Mazda is coming out or I may have to move to Cayman S. I have been buying Mazdas for over 20 years, but I am liking the new Porsches.

Ah I think the Axial Flow is waiting on the COBB AccessPort, so that is why its quiet. The COBB seems really close to releasing it for the NA RX-8 MTs.
However, it would be nice if RP teamed up with Pettit as they have an ECU flash for their SC kit.
Yeah Pettit is a supercharger competitor, but they have an ECU flash, and if the Axial Flow is going to be released there is nothing they can do to stop IT. So it makes sense to team up. Like the way Mazsport hooked Pettit kits up with the Int-X, until they got their ECU flash finished.

Turbo boost is diff than supercharger boost.
i figured the master would know that
duh
haha.
maybe he is saying that the flash is tuned for only a certain psi.
either way a flash is a flash.

Axial Flow 'Supercharger' = ...
As far as the engine is concerned FI is FI, how it gets there matters little at that point.

I agree that many on this forum know more than I do about FI.
So if someone has a flash for our oem ecm that will run a s.c. well, then that flash will work on all types of FI? Or all type of superchargers not tubo's?
Axial flow is a little different ype of s.c. also---correct?
Is Petit sitting on a goldmine and doesnt know it?

The issue is going to be one you know well - the idle bleed.
A well designed FI system will have all the air that enters the system accounted for utilizing whatever measurement technique that is employed. In the case of the OEM setup, this is the MAF.
Some systems will use a MAP sensor in lieu of the MAF or in conjunction with it.
One of the problems with the Pettit system (and subsequently, the Pettit flash) is that there is a deliberate "leak" to allow the S/C to pass air for idle that the MAF doesn't see. The flash, knowing that this is the case, adds back to the calculation the amount of missing air.
A normal FI installation won't have this "leak", so the flash will over-fuel because it believes there is some 40% more air going by that there actually is.
