HPTuners Nissan/Infiniti Inquiry

To start off, I'll start off by saying I have nothing but good to say in regards to HPTuners. Unmatched support for vehicles and issues alike. But, my main concern is I have a lot of requests for Nissans, and I'd much rather stay with HPTuners because their pricing and licensing is extremely reasonable. I am just wondering if there is a way we can get a bit more of a transparent roadmap as to what may change with Infiniti/Nissan support? If there is changes, when may we see them? I wanted to write this in the forum to allow other users of HPTuners to add to this if I missed anything. Thank you!

Hey guys! I just made an account here so I could chime in / subscribe to this discussion. I'm a new VQ37VHR owner (2010 Infiniti G37x). I recently bought an EcuTek kit for tuning but was considering returning it and switching to HPTuners. I got excited, made a long post about HPTuners over at myG37.com to discuss interest: Thoughts on HPTuners?

Then I come over here and see somewhat disappointing news. Does it seem like everyone has the same experience: Zero Gains when tuning our cars with HPTuners? How is it that UpRev and EcuTek can both tune these cars very well at all kinds of power levels but HPTuners cannot? I think HPT has been around longer, is bigger, has way more end-users and tuners, is more widely available, etc etc so what gives? Is this something that HPTuners software/engineers have to fix on their end with the capabilities of the tuning software suite? Or is it just that tuners aren't that familiar with these engines on HPTuners and just need more time/practice/learning?

Anyway, I'll continue to monitor for any progress... but sadly it seems this isn't the way to go for us VQ guys right now :(:pray::( It's too bad because outside of any of the little quirky stupid things like burble or pop things mixed into the tune (I could care less), it seems like HPTuners is feature-rich and has tuned so many platforms in the world with huge horsepower numbers. I have a friend with a 1200whp Corvette he tuned himself on HPT.

It seems that HPT provides access but the end user, especially with Nissan, must be very knowledgeable. The tables are there you just really need to know what they do. Uprev is so widely used by pro tuners and the company works with them exchanging info, therefor there is a ton of user info and guides available to anybody. 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.

Mislabeled parameters....interesting. I'm pretty sure we're the ones who corrected them and the industry just got used to the naming conventions and units other software uses.
