So I am ab to swap my blow 350z revup engine (2005 35th yr anniversary) with a non revup 04' de engine. I've been seeing that you need to change the ECU (which I know I have to) to a de non revup ECU and get the NATS flashed off.

I came across this website that says if I send them the VIN of my car they can make an ECU that is plug and play and send it to me, I'm wondering if I just get the ECU from this website if I can avoid having to buy an ECU and then paying to get it flashed. Will this work? hope I explained it well enough. !!! the Ecu from the website is a 04' de !!!

Just pull the heads and plenum off your RevUp and put them on the DE. You can save the $ and hassle of the ECU and you can do the timing chain, tensioners, guides, RevUp oil pump, galley gaskets, and water pump while you’ve got the new engine out of the car anyways.
