Hello,

I just bought a ECU for a erst (S2) with a chip installed (superchip).
Now I saw in the burton power catalogue that there are to kinds of chips for the s2.
Does it make a differance if you swap these when they are not the same?
Because the chipped ECU has following code (blue, red, white => early model), and the car it is going in to is a '90 spec erst.

Greetz,
