Okay I have just purchased this nistune Ecu for my n reg s14.
Me being me didn't check what I already have so when I've come to test it I pulled out this
I've Googled both numbers off the ecu's but don't seem to be getting any answers. Im guessing I'm running a later (14a) Ecu so therefore will need to buy a nistune chip or apexi etc Ecu to fit a 14a.
So if possible can someone help point me in the right direction on what I should be looking for.
