I have two ecu's out of two 90 n/a GTU Rx-7s. But different numbers on the top. One says N350 and one says N351. Does anyone know the difference? CJ

 

Now I'm scared...
I can't remember, but mine is one of those.....
I don't know what the diff is.

 

When i first bought my Blue 90, i had some problems. So i just started swaping in parts. I changed the ecu, and the injectors all at the same time. Fixed problem. Last week i swaped out the ecu, to make shure i was giving you a good one. Car ran the same. Just wondering if one had a little different fuel curve or timing curve. CJ

 

the n350 is the california, i have no idea what the difference is
