ECU tune finally done!!
The only thing is Tadashi is telling me there is more than 4 or 5 different ECU variants out there, due to the different options that people get. the only way is to pull the computer off from your car, and tell me the #s written on it, is the only way right now that i can say yes or no to if your car can get reflash. if we don't have your specific #, we might be able to work out a deal with you for being the prototype car-

So if I'm reading that dyno sheet correctly, for 6mt owners, we should see around 15hp increase from around 4K RPM on up to an increase of around 25 peak hp, and an increased redline of 500RPM, where the engine is at its best? Sign me up!

These numbers are exceptional. In the graph it's like a 25HP and 20TQ gain for the tune only. I'm going to wait for a while before I get mine tuned as I want to see how much more improvement can be had given time.
Remember. the G37coupe 6MT had a cat-back exhaust + intakes.
so expect bone stock performance to be a little less.
for those that are interested in prototyping, if you have your VIN#, you can call your Infiniti Dealer to get your ECU Part #. (should end in JK##)
we are looking for a JK72, JK73, JK74, JK76, JK77.. these are all the ones we need.. some of you have already PM'd me your part numbers, and those people will have first dibs when it comes to the sponsorship deal...
thanks

the ecus we can reflash now is JK75 and JK71.
I assume an ECU reflash could affect drivetrain warranty items correct?
Would the dealer be able to easily detect that it's modified?

To all that may be interested, Technosquare just finished the Reflash for the G37Coupe MT Prototype car. The car came to us already with a prototype HKS Exhaust (which includes downpipe and mufflers), but stock cats, stock headers, and aftermarket intakes were installed.
Got some good strong numbers throughout the entire band, and the car now pulls all the way to the new Rev limit, which is 500 more than stock (although on the graph, it doesnt show it, but it is.) Things changed were Timing, A/F, throttle control, rev limiter raise and speed limiter removal.
TechnoSq is quite happy with the results on this prototype car, this was done using 91 California pump gas. 324.9 rwhp, 250.6 ft-lb torque....
93+ octane states could see a little more with more advanced timing...
If you have questions, please feel free to PM me (i'll try to check back often) or you can email me directly.. Chezee350 at Hotmail.com.

Dealer will not know unless you tell them, or if they put in the consult II and start poking around. Typically they will not know. however if they drive it, they most certainly will notice the throttle body recalibration.
of all the 1000s of 350zs and G35s that have been reflashed before, none that i personally know of were rejected for warranty issues from the dealer.
