Some cars still use a MAP sensor, but they're not too common. Controlling idle with an AFM is easier than a MAP sensor.
Hmm, the Autronic website seems to be down for a revamp. It might be worth talking to the guys at Silverwater Auto Services, as they were the guys in the know when I was looking at Autronics for my last car.
I had a quick look at the MoTeC website and can't actually locate an ECU which will run 12 injectors natively, so that might not be the best option for our cars. It's odd that they advertise them as being able to work on a 12 cylinder vehicle, but not control 12 injectors. Probably just using waste spark and batch injector firing on a massive 12 cylinder lump and not individual control for each injector/sparkplug.
