Steady on...

James... I whole heartedly apologise to you for coming across as an ungrateful fuckwit and giving you a hard time for providing information to me. Once I've taken your advice used it, and had success with it, rest assured I would have been back on here blowing sunshine up your arris.

I do not have the knowledge of my car that you do when it comes to management parameters etc. I know that. So, Thankyou for the advice you gave me for free. It is of use to me, and I DO appreciate you taking the time out to help.

stu,
Stating that I have a good understanding, but not perfect is I think pretty fair. It says 'I don't think I know it all', 'I'm a learner on the yb', 'I'll understand a lot of your terminology, but not all of it so you don't need to talk to me in really simple terms, like a man who's never seen under a bonnet, but I WON'T GET some of it'
Or at least that is what I was trying to convey to him with that statement.
Yeah, it was maybe not edited in the best way, but it is just flat words on screen, and you have percieved me saying it out loud like a gobby tool. Had we been face to face, James would have been assured from my body language, voice and facial expression that I bore him no malice, and was in fact just stressed at the car and seeking his help.
You're not so shy of giving it on both barrells so you will understand I'm sure.
