Many thanks....But i have NO chip fitted to the ECU when i got it, so i cannot compare and old chip to this.
I purchased the ECU and NO chip at all was fitted.
I understand the notches and i admit would be easy if i could compare a chip that was already fitted , but i don't.
Jason's instructions where the notch faces the outer edge of the ECU...
Just need to be 100% as i do not want to blow anything.
Cheers guys

Anyway to avoid confusion, place the chip in the exact same orientation as the chip that is already installed in the ECU, to the left of the one you're installing. If you look at that chip it has the notch at the top of the chip and it has the little circle beside pin 1 like my earlier post.
Let us know how you get on but it really is as straightforward as that.
