S5 ECU Question?
Can smeone tell me the real difference between ECU number N351 and N353? I know 353 is for a vert and 351 is for a coupe. How are the electronics different?
Thanks for your help.

This was from Kevin Landers:
The convertibles run a n353, which is mapped for nonturbo (the stock convertible) as well as turbo. You can, however, run a stock 89-91 nonturbo coupe n351 ecu with no side effects; apparently mazda just wanted to put one ecu into all 'verts, and since theyre turbo in japan, they made the 353 to run both turbo and nonturbo engines.
I have several 351s if you find out you need it. hypntyz@charter.net
