I dont know why more people dont try (excuse the name) megasquirt ms V2.2 or v3 These are techincally a build it yourself ecu but can be brought assembled and have features to run pretty much any posible extra, my mates got one cost like £360 a few years back, prob more like £450 now but has data logging, lauch control, flat foot shift, switchable maps, Nos capabilities and loads more, Even the program to run it yourself and tune it on your laptop and theres a android app on the way for it that allows you to open up any or multiple gauges on your phone for easy veiwing. A very serious bit of kit for not too much money, most decent tuners will take one look at the mapping software and will know straight away there way around it!
