This article isn't a marketing exercise, even tho it was written by Andy from Adaptronic. I found it quite an informative read about the functions of ecu's, how ecu's deal with certain situations, and what to consider when choosing an ecu for your application. http://www.adaptronic.com.au/files/ecu-lowdown/20130920_ECU_Lowdown.pdf
One not so obvious thing for most is that even if two manufacturers advertice their ecu with traction control as an example, doesnt meen boths ecus traction control is equal. One may work brilliantly where the others sucks donkey balls. On paper (on the spec/ticbox list) they looks the same tho. Obviously doesnt limit itself to TC. Just food for thought...
