If I remember right. They have more RAM. There is basically 3 different ECU's for the years. '09, '10 to '14, '15+. Each up-grade has more stuff in it.

+1 I received the same information from a Nissan engineer that the ECU’s in all three of those years is different with the 15+ have more programming capabilities as there is more usable memory in the 15+ ECU’s. Also the reason why I purchased a 15+ Z was because of the fact that all conditions the same +15 Z will make more whp and wtq than pre 15 Z’s more so in improved weather conditions. I have seen this before myself you will never feel the difference only on your dyno sheet printout. Thanks for sharing Rusty.

Z1 told me the same thing. They seemed to think the headers were the main reason, though I'm sure the ECU variances Rusty listed play some factor too.

My tuner told me the same thing. Nissan made some minor tweaks to the ECU which bumped up the base whp slightly.

Well then I guess I’m F’d with my 2009...

Yeah I (2015) only race other Z's if they have fangs :icon17:

I'm putting down 344 whp with my 09. I seriously wouldn't let it concern you.
