Its really a big deal to do this,, like I said, it's taking a potentiometer reading and converting it in to a thermister reading..
AFMs measure air intake flow basically (and this is a very basic statement) but basically on a 1-100 type scale (i'm sure the actual numbers are very different..) A thermister measures temperature, and depending on the car and whichever other inputs there are, it reads the amount of airflow depending on temperature..
Now, in order to accomplish this, one must make a program (more specifically a series of algorithms) that will tell the computer "IF",,, "THEN".... I'm sure they have the programming done, or i would hope they do,, but working out the bugs on this type of system i would imagine could take years.. There was another m42 member that was looking in to this at one point and I believe he must have given up on it.. One there's no real gains,,, maybe better throttle response, but that's about it.......
All in all, I really wouldn't expect this project to be done anytime soon.. they certainly shouldn't have taken pre-orders yet.. Good luck to all who have ordered it!! I hope you preorder for reasons that you've done research on, and not just because it's "cool"... I think if you haven't done your homework, you're gonna be seriously dissappointed with the results... that's my .02 anyway......
