Questions our customers have asked
I was curious as to what the options are to return to stock after this tune?
The Osiris management can carry a stock tune and the software is also removable or transferable to another compatible vehicle. This is a huge perk with Osiris software compared to the competition.
Is this product compatible with the vq35de engine and ecu in the g35? If so is there any other equipment I would need to add to my car to make this work properly? Thanks
It will work on all G models except 2003 G35 Automatic Sedans.
Good morning. I am interested in the mail in flash service. What size intake is considered oversized and cannot be programmed via mail? I am considering either Mishimoto 3" or Admin tuning 3.5" intakes.
Unfortunately, we only offer the mail in service with intakes that retain the OEM diameter at the MAF sensor. Larger intakes manipulate the MAF reading and cause complications that need to be worked out on a per a car basis on the dyno in order to guarantee a safe quality tune.

The tune is great! It’s been super fun, but I would have perfected it if it came with instructions because I had to Google how to use it. I would definitely recommend getting an Uprev tune. In my opinion, it’s definitely worth it. The anti-lag feature is the best one. Hopefully, I win the 370 giveaway :)

10/10 highly recommend for anyone with a VQ37. Got this for my FBO 08 G37 Coupe performance is night and day compared to stock tune. The car runs smoother shifts better and overall better performance, couldn’t be happier with it.

Hello, i recently ordered the uprev mail in service after finishing my exhaust and intakes. The package really wakes the car up and for being naturally aspirated a tune really helps with acceleration. Thank you Z1!

It all started with NATS issues on and off for a few years, until the 350z finally said "absolutely not". Decided to mail in the ECU mainly for NATS delete, but figured I might as well add a little "juice" while it was there, and opted for the ARC features as well.
If you're on the fence, ADD THE ARC FEATURES. Trust me, they are worth it in the long run. You get the five different maps which adds a lot of flexibility to your driving experience in the car, plus all of the 'fun' features like the adjustable launch control.
I noticed a slightly better pull through all the gears, especially at higher RPMs. I wasn't looking for any significant gains, or I would have hit a dyno, but you can tell a little difference.
Thanks to the Z1 Tuning Department!

11/10 Service, took about a week to get it tuned and sent back but well worth the wait. Feels and preforms better than ever, plus they let me choose what maps I wanted! Highly recommend, feels smoother than my previous Dyno tune.

If can't data log for e tune or (like me) a Dyno is too far away, this is the option. Guys were very helpful and informative, even though the scared the crap outta me when they said UPS didn't deliver my ECU when they said it was. Nonetheless, like others have said, it woke up all the my mods I did and everything runs so smoothly now. Even with a NA build, you can see all the potential these VQ platforms have. Thank you Z1 as always.

Great value for the performance. Car runs significantly better and the internal dyno definitely feels the power upgrade. Turnaround time was quick and communication was great. Might want to include on the spec sheet what maps you want (performance, eco, valet, etc)

Z1 was great fast turnaround less than a week my car was down. My car feels amazing worth the money with my bolt ons. My G is even more fun to drive now. John was on point answered all my questions before I mailed my ECU in. I would recommend if your not able to get your car into a tuner and are unfamiliar with the e tune this is an excellent alternative.

Money well spent! I own a 2003 Z as a project car and I broke my only key and lost the transmitter chip for it. Not knowing that it needed the transmitter chip to start the car, I activated the NATS and had my car in lock mode (P1610). I tried whipping the codes with a scanner and had a locksmith try to program a new key and I personally don’t like dealing with the dealerships. So I had little to no success to get my Z running again. But thanks to Z1 Motorsport for having the NATS Disable option with this tune! I am happily able to drive it on the road again!

Car seems to runs smoother, noticeable power gains, RPM's when shifting is much smoother. Even coming from a dead stop is smoother. Not sure how to adjust the maps, or what the maps even do, no instructions provided on how to adjust. But i'm happy with the purchase, wish i did it years ago

Had my car dyno tuned at Z1. All I can say is it was a night and day difference once I got my car on the road...felt like a new car, more sharp and awake, great response on the throttle. Should have came like this from the factory.

Got this Flash to disable antitheft. The work was done quick and the antitheft is definitely disabled.
My 350z had/has electrical issues that kept the car from starting. I tried to solve these gremlins for almost two years before finding this solution. My car started right up and drove perfectly at an all day drift event.
It's been too long since I drove the car to notice a performance difference.

Works flawlessly. I dropped it in both my daily and project expecting some complication but with the NATS deleted, not a single issue. The staff at Z1 are great to work with, very helpful. I mailed it on Saturday with Monday being a holiday and got it back Thursday. Even after I emailed on the holiday to add the NATS delete they were able to stop it from shipping, get it done and to me in three business days! Who does that?! My 3.5 to 6krpm gains are what surprised me the most. The upper is heavily ported(137grams removed) with 5/8"spacer, now 3rd is actually a fun gear! If you've got sceptecism, all I can tell you is that I did too. For nothing. I'll be a return customer.

To my disappointed surprise, A Professional Tuner checked my ECU before my dyno test to find out the only thing Z1 mail in flash has done is tweak my air ratio, that's it...!! for that price for something that simple, yea I'm bit upset.

I have one of the most basic 350z with simple bolt ons which include test pipes, plenum spacer, aftermarket exhaust, aftermarket intake, light weight flywheel, ungraded cd0009 trans and with the tune I swear this is a whole new kinda beast. I’m not talking about numbers here I’m talking about butt dyno, how she feels and lets loose. Responsive and the with the rpm increase to 750-800rpm clutch chatter is gone. Power is pretty impressive. Should of got this done a long time ago

Great customer service had a couple of questions before I felt ready to ship my ecu and they got right back to me and answered all of my questions. Really easy just shipped it in to them and they toke care of everything quick and sent it right back out after the tune was done. Couldn’t have ask for better service and really brought the car to life with all the bolt on I put on. Thanks z1

I wasn't sure what the results would be but, dang! It's a new car now. I have all the breather mods and the car is so smooth now. The car has more power all the way up, and the turn around time was only 3 days!!!! Very impressed. I can definitely recommend this for a quick tune.

A power difference even with a stock car.
Extremely happy!
I know there is a huge difference
In the power band all the way through.
Thanks Russ and everyone

I was slightly skeptical about this reflash at first but decided I'd give it a try. It was a night and day difference for my car with some simple mods. Everything about the car feels better and faster now. Don't get me wrong I loved driving the car before but now that Z1 did their magic on it, it is a blast to drive. The team at Z1 was also very helpful as they explained what they do with these and what you get out of them. 10/10 stars on this reflash. It exceeded expectations for sure.

Totally worth it for budget builds. I'm always on call and never know when I'll have a day off to spend at the tuners so this was perfect for me. It is a night and day difference! I have all breather mods/bolt ons and was running lean but now there is no hesitation, it pulls hard from every gear, no idle dips or CEL's. Best if all was I sent it out and got it back in 6 days, super quick turnaround. 5 stars
