I've never heard of any high profile tuners using this platform so there's very little help out there. That being said I've spent the last year researching info on Uprev and found a lot of Nissan specific info on the GTR forums and successfully tuned my 07 Z with a S366 turbo, 850cc injectors and 3.7 bottom end. I've learned a lot for sure about what parameters need to match for the Nissan ECU to run properly. I've found many of the tables here have mislabeled parameters or units, some tables don't do anything like cooing fan control and tire diameter. The engine operating parameters are there though and they do make the intended changes to the ECU. I'd love some more control like anti lag, launch control and a speed density option but I can't complain for the price. This allowed me to get into the tuning game but a Proefi stand alone is my future for sure.
