After some careful thinking and pricing im tempted to change away from my OFAC EFi setup to either Megasquirt - due to Karlos' success or Cossie Management - due to Jano's recommendations...

Opinions on what to go for please!?

My main concern with MS is that i've never mapped a car myself or done anything similar, i can do all of the mechanics etc but the science involved in mapping worries me greatly that i'll end up with a car that won't run right or safely for months and i won't have any enjoyment from it. I don't mine putting in the time to learn how to map the MS but i don't want to get stuck in the middle of it and be back to square one! Whereas the cossie can be installed and mapped and i can drive the car days/weeks later!
