Gentlemen:

I have ordered a Stage One performance exhaust from an American Morgan dealer. They indicate to me that I need to send them my ECU in order for them to send it to Morgan Motors in Malvern to have it "flashed".
I note from the posts by Black Adder et al. that my present ECU, which I assume is locked, will work with the Stage One kit. As I am hesitant to send my ECU away to have it remapped, or reprogrammed, or flashed, etc., kindly communicate to me whether I can install my new Stage One exhaust and use my original ECU. My 3W was manufactured on 09/2015.
Thank you very much.

Tom
