ECU problem running
hey guys, so i have a 03 350z and my old ecu is jacked up. it keeps going into limp mode every time i go into high RPM's. so i ordered a nother one just like it. when the new one cam in it started my car and ran the first time but then when i tried to start my car the next day it cranks but doesnt want to turn over does anyone know what it could be? the weird thing is that the old ECU/ECM when i put it back in the car starts right away. do i need to go get it reprogrammed to my car or something? im lost here, i even got a new battery so it couldnt be the battery. please HELP!

okay so just go to the dealer and get it reprogrammed correct? i asked the dealer for a price and they said it would be around 150 to get it programmed. i just hope that works because that would be a waste of 150 if it doesnt fix the problem...

You can turn of NATS with Uprev. If NATS is indeed your issue causing the new ECU to not work (and I expect it is), an Uprev tuner can turn it off on your car as part of the tune. Then any copy of your key will work whether or not it has the security chip.
