I looked into this a while back when I was after new management, I spoke to Corten Miller Performance who specialise in these ecu's I wanted the 700 mainly as it could control the boost, but they recomended I get a blitz controller as the ecu controlled option was not all that. This actually put me off buying the whole ecu as its was a pretty expensive bit of kit and when you are spending that sort of money I would expect any features it has to offer to be spot on and faultless.

Probably a non informatice post so soz, if you give them a bell on 01754820341 and ask for Ben, say I pointed you in their direction thay can answer all your questions as like I say they work on most of Omex's ecu's day in day out.

Hope this helps
