So far I have few throttle Maps made on this forum that is specifically designed for EX35 5 speed A/T and it does work for the G37 7 speed A/T too!

If i actually knew what it was/how to do it, and could afford it... Id be all over it. id love more power, and better gas mileage
It is a very popular ECU tuner for Nissan/Infiniti car. You basically buy either a standart ($500) or the tuner license ($700) package which include the cable that you use to plug in one end to your car's OBD2 connector under your dash and the other end to you window based laptop.
These are the parameters your tuner can change on your standard license.
From UpRev website.
Osiris Standard:
Osiris Standard includes the UpRev Interface Cable to reflash and communicate with the vehicle through the OBDII Diagnostic Port. Osiris Standard also includes Map Switching(with cruise control) -- allowing you to use different tunes for different situations -- and 3 eTune updates. eTune updates must be used within 1 year of purchase and are non-transferrable.
Osiris Standard is a licensed based system meaning your license will be transferred to the first ECU that is flashed. This vehicle can then be flashed as many times as the user wants, but the flash will not work on any different vehicles. One additional license can be purchased at a discount for enthusiasts that may have more than one vehicle, contact us for details.
Parameters that we will tune include:
Up to 5 Maps (only on supported vehicles- check our Support Matrix for verification)
Idle RPM
Speed Limiter
Rev Limiter
DTC disable
Fuel Compensation
Ignition Timing Advance
Tuner license :
Osiris Tuner
The Osiris Tuner system includes Cipher, Map Switching, the flash utility and our powerful, new 2.0 ROM Editor. Osiris Tuner supports NA applications and high horse power forced induction vehicles. Using the UpRev GT MAF, upgraded injectors and high flow fuel pump we have tuned for over 550whp on the G35.
Osiris Tuner is a licensed based system. The purchase of Osiris Tuner includes one license that will be transferred to the first ECU that is flashed. This vehicle can then be flashed as many times as the user wants, but the flash will not work on any different vehicles.
Osiris Tuner does not include any base maps or eTunes, the user is expected to develop their own tune for their vehicle using the stock ROMS included in the software package. Paid technical support can be found through UpRev’s Pro Tuners.
Parameters that are supported in the ROM Editor include:
Up to 5 Maps on cruise control equipped vehicles
Idle RPM
Speed Limiter
Electronic Throttle Control to achieve Wide Open Throttle at all speeds.
Rev Limiter
DTC disable
AFR Targets
Fuel Compensation
Ignition Timing Advance
Cam Phasing for equipped vehicles.
MAF transfer function
Cranking Enrichment and Ignition Advance
Injector Latency
K Fuel Multiplier
Intake Temp
Calculated Load vs. RPM
Minimum Effective Injector Pulse Width
There are 2 better ways to get this installed in your car. Actually, 3 ways, but you'll benefit more if you follow these two.
1) You buy the standard version and pay for tuning. I know someone who can E-Tune your car for $100 unlimited data tunes. So basically all you need are,
- Uprev Standard License and Cable : $500
- Etuner fee $100
- Windo base laptop
- Your time data logging
total money spent $600
Etuning means, your tuner from out of state or country will send you a base map to flash into your car's ECU using your laptop, cable etc. You then use the UpRev sofware to data log your 0-60/ 0-80 MPH and hwy/city cruising. Everytime you data log your performance run, it creates a file. These files can be sent via email to your Pro Tuner/Etuner. Your Etuner remotely analyze your data and make some adjustements on your Air Fuel Mixture, so that when you floor the pedal, it does not go very lean and damage the engine in the long run. Also, if the car gets too rich (typical stock Infiniti setup) you do not waste gas for being too rich on Air/fuel mixture. He can also change a lot of parameters such as throttle response etc.... Etuning is 90-96% close as you can get to achieve the car's performance potential vs tuning the car on the dyno which cost $250 + per hour cost.
2) You buy a Tuner version and do the same thing above, except the Tuner version, you have access to the tune files and can make changes to the tune.
The Tuner version also has the ability to check engine light codes and turn it off and also can clean learned fuel maps , etc, Both the standard and Tuner package has the ability to view live OBD2 sensor parameters. Tons of them! (e.g. Air fuel mixture, Tranny Temp, coolant temp, etc...) These tons of Info alone cost $300-400 already if you have to buy a stand alone OBD2 reader. I mean the real one. Not the cheap tiny OBD2 you buy on Ebay and monitor using the cellphone..
3) Option 3 is not ideal since you pay more than option 1 or 2. option 3 is you go to licensed Uprev Tuner and pay him $500 for the license (but no cable) and you pay him the cost of dyno tunes. (Dyno cost is around $200-250 per your)
He tunes your car and go home with that tunes and no option to change the tunes unless you go back to him and pay him again for another tune if you decided to add better exhaust etc.... (It is ideal to tune the car with aftermarket performance parts already installed) though, even a stock car can benefit with using the Uprev Tune since, the air fuel mixture are optimazed and the throttle response are night and day compare to stock.
When you have to service your car for warranty work, you need to flash back to Stock ECu setting (file is provided by your tuner/Etuner) If you go option 3, make sure you ask them if that flashing back to stock is free. After the service, you have to go back to your tuner and flash your Uprev Map again. You do not have to dyno the car or do data log again since you already have that settings in your saved Uprev file you stored in your PC. Option 3 also means you pay more for the Uprev License since it does not come with cable. With option 1 and 2 if you sell your car, you can sell the cable w/ license and sell it for 3/4 the price of brand new Uprev. (Sell it to Nissan forum or the G37 forum)
You can also either Etune or Dyno tunes option 1 and 2, It's just cheaper to go Etunes...
BTW, I bought my tuner license /cable slightly used on Nissan forum (titan talk) for $400
and found a protuner /Etuner uprev certified on the G37 forum name Seymore4 . He did my Etune and I played and created my on throttle Map setting were the response of my EX35 throttle pedal start at 1/4 pedal push and responsiveness starts at. 2k RPM vs 3K RPM on stock throttle map.
The good thing is, my car is a test car and I am very familiar with this Uprev process. So if anyone decided to Uprev, it will just be a piece of cake since I can help you out if you have question.
BTW, I believe Seymore4 also sells the Uprev license and cable cheaper than going direct to Uprev. Uprev also charges $50 per Etune data lot vs Seymore $100 lifetime/unlimited log. Seymore4 can send back an Etune map file in a day or two vs Uprev Etune of 2 weeks.
Basically for me I only spent $500 and the car runs great night and day vs stock.
