hey guys,
I've been reading a lot about the ECU flashing for my 03 G35 coupe 6mt. I had a few questions answeed but have a few more. I'd rather buy an extra ECU to tune and have my stock one as a spare. Do I have to buy an ECU specifically from a 03 G35 Coupe 6mt? or will any ( maxima, altima, g35 sedan, 350Z 2002-2007 ) work for my 03 g35 coupe 6MT.
Also, if anyone has any knowledge, what are the hp and trq gains on a stock g35 with the L-spec tune ( meaning just the 100% wot and the 7100rpm redline ) ??

Thanks

 

No, they are not the same. Same engine type does not mean tuned the same.

 

And each ECU is only compatible with the car it came with for the G35's. So I heard. Any correct me if I'm wrong. In other words I was told if I bought another ECU from a wrecked G35 it would not work with my G35. They can however clone your ECU at Altered Atmosphere Motorsports if you want to have an original and have one tuned.

 

heh, wow, this is a first that i am hearing of something like that, thank you for informing me, do u have an idea of how much the cloning costs, and if its necessary if i would be flashing the ecu anyways.

 

I heard that after a year or so, the car deletes the tune slowly (since it has like the driver style thing)
