When I say idiot I did not mean they were not up to the job of competently mapping an ECU it was more to do with their general demeanour. I arrived at the agreed time and was then left standing there for 20 minutes after I'd introduced myself while they chatted between themselves (idle chit chat, not work related) without even a sorry we'll be with you shortly. He eventually plugged a laptop in while telling me of all his achievement and how everyone else couldn't map to his standard, after a cursory look over the existing map I was told they were too busy for the next couple of weeks and to call back later to book an appointment. I thought I had already made that appointment as we'd already had a 30min long conversation 2 weeks prior to turning up where I told he of my exact equipment’s, the spec of the car and it's intended use.
Most of the people that do use them are only grass roots motorsport participants which I would certainly class as the 'general public' it's hardly like they are used dealing with the likes of Mclarn, Farrari, Prodrive ETC..
