I've been using a SBC id-III for about 2.5 years now, it's been a great device, easy to setup and use.
I think this is a very good update on that product. It is very expensive, a lot more than the id-III. However it seems to offer the same range of functions (in one box) that the combined id-III and Power Meter offer; power curves, rpm based boost control, so that could save on the cost of 2 units. It also offers additional inputs for (expensive) external sensors and the external harness for voltage inputs (this is available on the id-III too).
I wonder if the i-Color Display works with the same box of electronics used with the id-III display? I think I maybe tempted in the future if it does......once they start appearing on eBay though.
