I need to test the ecu on a friends car. Would anyone happen to have a spare 04 g35 auto ecu for sale or to borrow?

Located in the East Bay

 

If you want to "test fit" one, you'll need to get one with NATS removed, otherwise you won't be able to start the car. You can get a used one off of car-part.com for cheap, I just ordered one for $125 shipped.

 

+1 Even if its the same ECU from the exact same make/model/trim with the same ECU part # you can't just plug it in and go, you have to either get it reprogrammed at the dealer or disable NATS with Uprev. If you need help with disabling it or have any questions about how it works PM me.
