Guess what this is?

Load scaling can be changed to what you need for boost also. You should be able to change the scaling on the axis to get more resolution where you need in all of the maps. If it's a MAF limitation, that can be taken car of in the ECU too. These are not limitations of the stock ECU, but limits of the knowledge of the ECU itself.
Not trying to bash, only educate.

As for the load limits, let us know what he said that isn't correct.

This can be compared to the fractions of a degree increments that the XEDE can change timing. Not a big deal in Suby applications where timing numbers are always in the double digits (even under boost). In an EVO, total advance is between 0-6 degrees throughout the entire midband. This makes +/- 1 deg changes less than desirable.

The load scaling (and just about any other scaling or axis) can be changed in the stock ecu. If you hit the MAF limitation, that can be handled in the stock ECU. That all I'm saying.
The limitations you speak of are a limitation of the tools being used, not the ECU.

. In the stock ECU you can resize the MAF sensor, change the filtering off throttle and on throttle, rescaling the MAF sensor scaling table 2D map, and change the MAF tweak table 2D map. When I reflash Evo's with bigger turbos, I am able to change these values.

If the software for this is anything close to HPTuners software, you guys are going to shut down every single piggy back user on the planet. GOOD FOR YOU!!! Now give it to me!!! Before I have to come hurt you 
Seriously, when is this comming out????

Better get AccessECU to hurry up and get the EVO accessport completed. What really baffles me is why domestic cars have hand held reflasher for a dime a dozen ($100ish) and it costs import owners an arm and a leg for almost the same thing ($600ish for an Accessport).

BTW I am even shocked at the capabilities and uses of this new product, In a very short time I think everyone will be too.

i have the v360 but i never sended my ecu for the xedeflash should i send it or wait for this product?? is it going to be thhe same as the xedeflash?
thanks
