Why would you want to do this?
If you want very simple control for a track car, you can kill most convenience functions. Making it throttle, fuel and spark only without torque control and other stuff.
Most times when someone asks to upgrade the engine management system, I push them towards swapping ME7 in over standalone at this point. I realize this does not apply for every situation. On a side note, I once made an 034 standalone system control the Haldex, and machined the case to make the controller manually adjustable from the outside. This was a track car. I'm in the process of doing Megasquirt on a 16v, and it's a good unit (feature-wise) for the money, but paying a shop to do the install really evens things out cost-wise.
