MonteZooma, I've tried various ways of finding things out and I always end up back at the factory, or as you say staring into a black hole. I suspect they own the software and unless someone tells me other wise, I'll have to assume I talk to the factory and the ECU can't be 'fiddled with' by 'outsiders'.
I must be fair to the folks at Malvern, they have got mine running pretty nicely. I was just hoping to see if I can tap into more 'potential' without spending a fortune. The Subaru experience was interesting and it just struck me that the Duratec must be willing to offer an extra 20bhp without too much trouble.
