Voltage scaling for the most part. At 400hp the stock MAF is at its 5volt limit as it reads that much air volume. The modified MAF runs about 3.6-3.9v at around 550hp with plenty of headroom.

We had it made because Osiris Tuner allows you to tune for big power forced induction builds.

I have an APS twin turbo, which places the factory MAF sensor in a larger diameter air tube. My question is "would this screw up the calibration on the your new MAF sensor"?

You can use our Modified MAF in the stock size tube to a rated 1000hp (we'll test the manufacturers limit when we get a car that makes that much power) or you can just recalibrate the stock sensor in the larger tube... but I'd be hesitant to do that with questionable air flow stability in the larger tube.

The only thing the 512k doesn't currently have is the recovery program. You have to make sure your car battery, and your laptop battery aren't going to die, and that your cable isn't going to unplug during the flash.
The upgrade is being worked on as we speak (literally) and will be updated as soon as it is working and stable.
At the worst we have the best ECU support for the 03 and early 04 models, and we can recover the ECU if anything goes wrong, just ship it to us and we overnight it back for free.

STS puts the MAF post compressor and intercooler, assuming the intake piping diameter is the same, would this work for me? The UTEC works great. What would I gain from going over to Osiris? I expect that the stock ECU would provide seamless boosting but would the resolution be as a good as the UTEC?

Based on my understanding, if you're using the stock MAF, then you'd be limited to about 6 psi. A new MAF with greater airflow range will have a new calibration curve, which I believe is provided by UpRev. Osiris has full control over the stock ECU maps - much better than the UTEC, in just about every way EXCEPT that it does not use MAP (FWIW). So idle control, injector resizing, cam control, target A/F mapping, graphical user interface, temperature compensation maps (that actually work well), adaptive trims, CEL control are all in your grasp with Osiris.

We provide a basic curve to start from when using the stock tube and Modified MAF with Osiris Tuner. You can adjust from there if you need to, or you can use an alternative MAF/tube and use our software to recalibrate it.
We just wanted an easy solution for our customers, something that works well, is reliable, and simple to duplicate.

MAF only reads to 5v per spec. Thats why the Modified MAF needs recalibration.

correct me if im wrong plz....

The reason Tuners use a base tune on aftermarket stand alone ECUs is because they need to be able to make the car start, etc. The stock ROM already has that stuff in it, so theres no need for that with our system.
