Having read Tim Frost's very informative article and trawling all the available threads on the forums there does still seem to be a few gaps in my knowledge on how to implement this converstion.

I would love to hear from anyone who has done this conversion, how they dealt with these issues (I'm hoping to add this info to my 2T-->2TGEU conversion thread):

What ECU did you use? Fuel or Fuel/spark.
What coil/ignition set up?
How did you retard the ignition to avoid detonation? Crank angle sensor?
IC or no IC, if so did you use a BOV?
What sort of O2 sensor?
Did you install a knock sensor?

Any useful comments appreciated.
Thanks
Seb
