I was wondering if there is a better ECU than an N338? I know that all of the FC's at the race track are running the N326, S4's and S5's. I asked one of them and he told me that th 326 was the best stock ECU due to the lack of harsh emissions and restrictions for fuel economy. Can anyone verify this? If so I will put the 326 I have in my garage back in. Thanks for reading, Jack

Run an auto trans one.

Someone claims the aggressive timing curve on an auto trans ECU makes the manual FC faster.



Higher part numbers on mean newer ECU's but not necessarily better.

Ok, when you say, "ECU out of an auto", do you mean just any ECU or is there only one that came in the auto? have you heard how much of a timing curve?



DOES ANYONE KNOW WHERE I CAN GET MY ECU PROGRAMMED OR FIND A PLUG AND PLAY UNIT?
