It's possible if you know how to tune a VQ.
Or you can contact Uprev and ask them for the e-tune.

If you want to really fully tune it yourself, you would have to get the $700 Osiris Tuner. It has no base tunes so basically you need to know how to tune the car very specifically.

However, if you dont want that, then get the Osiris Standard, which is cheaper and has 3 e-Tunes included, so you can get one at the beginning, and if you happen to put bolt-ons later, you can get it re-tuned to account for that mod.

If there's an experienced nissan tuner in your country though, I would think they would be able to become an Uprev ProTuner and be able to do custom tuning for you...

good question, Im wondering about this tune also. the uprev tune you get from a performance shop with a ecu tuner or something? does it help or firm the 7at trans shifts also???

Unless you really know what you are doing, find a shop that will do it

e-tunes is your way to go, don't attempt to tune on your own

The purpose Uprev Osiris is to fine tune your engine parameters so that the car runs in the optimum AFR and timing. As a result, you'll have smooth running engine and usually higher performance figures. This tuning process is very advanced and requires repetitive runs on the dyno while controlling multiple parameters. It's not like a pre-made patch that you can just install. All the numbers and tables have to be adjusted according to your car. Unless you have experience in this field, you'll probably make your car run worse by tuning it yourself.
