Sorry, I shoulda been more specific
My main interest at the moment is learning how the different components
work together,what happens when this changes etc
So I am just WATCHIN' via scan tool on standard systems so I can learn
what ta read when customer says flat spot etc only happens once every
blue moon
Changin' parameters is way over my head at the moment,if and when
I get there I will do things right as you suggest
but for now I'll just lurk inside my ECU  ;-)
Thanks
Geoff
