As above, Kev is the gaffer at clinic. Clinic is the only place my car goes :)
Ecutek or Open source is a fairly hotly debated subject, each has its benefits and drawbacks. Ecutek is typicly more money for first map due to the license fee, after that they are the same price (set by the mapper/company).
On the flip side if there's any software issues or glicthes ecutek support their mappers, my old hawk had an issue with it kicking up a CEL, had it been opened sourced it would have been an issue, instead the fault got kicked back to ecutek by pat and they custom wrote a pacth for the software that has since gone into the latest Ecutek software.
Ecutek vet the mappers so can't just download and map away. Make of that what you will, but personaly i would rather have the back ground tech support that Ecutek have rather than googling for answers.
My type R now has syvecs fitted and thats a whole different ball game, same mapper mapped it, Pat Herborn mr syvecs himself :D
