Are there that many variations BC?
I thought they were either Motronic or Jetronic.
But I'm fick.
Sorry Mr Smooth but the anwer to that question is yes - several versions
And as an aside it should normally be changed as a matched pair with the spark control unit (although I have swaped the Odd ECU on it's own and it hasn't seemed to make much difference)
Best thing with any electronic control unit is to have the number off it then you know you are replacing like with like
One of the continental ABS members melted a piston or two on his Omega Evo500 - ECU turned out to be a 3.0 12V gold top one...... not very clever and he had no idea that it was wrong
