I’ve got a 2016 Supercharged Nismo and a std 2018 Nismo, apart from the boot release button on the centre console and differently colour door handiest along with clutch I though the cars were identical

Also make sure you change the original 1.09bar MAP sensor for a 4 bar T-MAP sensor. You may also need an air temp sensor plumber into the stillen inlet or possibly use the T-MAP to monitor air temp.

Also love these gauges, may look into getting these fitted to mine

I don’t need a bigger sensor because I’m only running 7lbs of boost and the stock sensor will read that fine. Up to 14lbs of boost.

Could always leave one gauge still wired but drop it behind the radio, leaving you a space for your gauge and factory gauges remain working.

UPDATE:
The tech Tried to leave for the dyno, car threw a check engine light 10 minutes from the shop. They scanned it and it has misfire codes

It looks like the tune file uprev sent them isn't working and without the proper base calibration They can't tune the car. This was 6:30pm so UpRev can’t help till tomorrow. Gauges are in. So frustrating cause it took Uprev week and a half just to send the file cause they were out of town and now the file they sent doesn’t work. So hopefully they will re-send a new file QUICKLY.

That sucks.

Upgrade to Topgunz A2A kit can build a custom tune. You’ll thank yourself in the long run.

Sounds good but that’s another week waiting for parts and more $$ and then another week at the shop and more$$ to pay them. I think, we’ll I hope UpRev can send a new file in the morning. All what is left is the tune then dyno.

Sorry if I missed it but what shop is doing the install? I'd like to give them a call about the center gauges on the '13-16 years.

So I asked them more about it and it was 350z from 2003-2007. I think since they did it before it would work with my Nismo. But the shop is ARautoservice. Here is the website and it will have their phone number and contact info. Ask for Martin. AR Autoservice

All what is left is the tune then dyno. I’m not happy with Stillen or Uprev. Very upset. First the Stillen rep “Dean” treated me like total crap over the phone when I questioned why Uprev was taking so long and why I wasn’t told about them leaving town He told me it’s my fault and not to call him back and to only talk to my shop about it, and that he shouldn’t be talking to me. I just spent thousands of dollars with Stillen and they treated me like “don’t call us, it’s yout fault and don’t call us back. I didn’t want to mention all this but hell im a customer! And now it’s been 2 weeks And Uprev sent a bad file. Very turned off on how stillen treated me and how there was no support from Uprev. We will see what uprev does tomorrow but I know in the future I’m not buying ANYTHING from Stillen.

Sorry to hear your troubles. Sucks when things don’t go as you plan. That’s why I’m a big fan of DIY but you have to be comfortable you can do the job.

Sounds like it is a no go. Thanks for the info. This is the first time I have heard about this even being possible and I was hoping for a good outcome. Those of us with Ecutek have to rely on the oil gauge still working as it taps into that. If this was possible it would open up options of adding more gauges without having to use the cubby space or for some people having to buy an aftermarket a-pillar.

Can someone explain to me why after flashing the tune with UpRev that check engine light would happen and it pulling tons of fuel and misfires?

jchammond 05-25-2018 03:33 AM
I’m pretty sure TopgunZ could help steer you through this; even though you don’t have his upgrade version,,,he’s probably the most experienced.
The location of the mafs have been an issue in the past- but I’m surely no expert on the kit.

Bikeracer1098 05-25-2018 05:40 AM
The problem I’m finding is the position of the MAFs which causes turbulence and inaccurate readings. The car needs a new MAP sensor and need to be mapped to the MAP sensor and air temperature rather than the MAFs

I’m just going through the process of getting mine set up correctly.

hustleman222 05-25-2018 07:57 AM
You may want to do an etune with someone who knows the cars a little better...if you use the Stillen base map you are looking at a really conservative tune...maybe 380 whp.

cadoo 05-25-2018 08:15 AM
My understanding on UpRev is there are 2 ways of tuning. Street tune were you download the data files then send the data files to Uprev then they send you back a tune. The other way is you go to a dyno and have them tune it with dyno. Am I missing something? Does the dyno/tune shop have to be UpRev certified or can it be a regular dyno/tune shop. Also wouldn’t taking it to the Dyno/tune shop fix everything and check engine light regarding the misfire code? Why if they were taking it to the Dyno/tune shop would they need a new file from Uprev just because of a check engine light?

jwick 05-25-2018 08:37 AM
The UpRev tune might be locked. If that’s the case then the shop isn’t actually doing anything but uploading the tune and verifying power on the dyno. You could actually upload the tune yourself. If the tune isn’t locked then the shop is just using UpRev as a starting point so they don’t have to build the entire file from scratch. VQs are tricky to tune and I wouldn’t want just anyone building the tune from scratch.

On a topic listed above, the location of the MAFs is the primary problem with the Stillen kit. They are preSCer which basically means the ECU has no clue what temperature air it is receiving.

Suggest you get an ECUtek tune

Try contacting - ByThaBay, Seb@SZ who both do ECUtek mapping & TopgunZ

Ok update:

they originally sent the shop the wrong tune so this morning they finally sent over the correct tune BUT, Uprev wants to update the software before the flash and of course Uprev website is down! I also tried and failed to get on. Is there a way to bypass the update so they can flash the new tune? Do you have to be connected to the internet to flash a tune file?
Man one thing after another!

https://www.uprev.com/ Is down. Screenshot attached

Called Uprev and the person on the phone told me he’s working on it but he’s stumped and has no idea when it will be back up. Also said that you can’t bypass the software update to flash a new tune. WOW!

Thanks for that! Pulling my hair out today so thx.

Update:

The shop took it for a test drive. It drives well but it popped a check engine light on. Fuel trims look good so the tune is good. It seems like it may have a vacuum leak. They are doing a smoke test. Boost was at 8.5 pounds

Great news guys! They found the leak and then went for a run and no more codes or problems! They said it was the fastest 370z they have ever tested. Here are the pics. On my way to pick it up! Will update with video later. It’s running great and zero problems. Going to get a custom tune from scratch on June the 7th. The canned tune is running great but would like a custom tune.

jwick 05-25-2018 04:47 PM
Congrats bro! Enjoy the boost club.

You were right on target! The file was locked from stillen and you can’t change the values or improve on the stillen canned tune. On June the 7th a tune shop that is approved by Uprev in Portland will get rid of the stillen can tune and make one from scratch. The stillen tune is running good so far.

Thats one great looking Nismo Z cadoo. Congrats!

So on the way home THIS happened! Cuts out at every light or stop sign. Can’t go over 3000rpm or the fuel starts cutting and popping. It was fine when I picked it up but 20 minuets later it went in some limp mode. Check engine light will go on with the cuts at 3000rpm or close to it. But as soon as I go under 3000rmp the check light turns off. My clean Nismo was black with sut in the back bumper and below wing. So over this.

UPDATE: Had nothing to do with the tune. The cupler
Came off and tons of air was escaping causing the car to run super rich and go into a limp mode.
After I discovered the problem it runs fine. Also the exhaust is fine 2. So again was not the tune. Was tons of air open. Below post is a picture of how I found it. Need to get better straps. Also the wires they ran for boost and the 2 other gauges is kinda in the way. Had to take strut bar off to get it back together.

Use a little hairspray on the pipe when you put it back on. It’ll make that stick real well.

I also recommend t-bolt clamps over worm driven screw clamps cuz they can chew up the silicone.

jwick 05-25-2018 11:20 PM
What changes did you make to the exhaust? Did you remove the factory cats? If so, the black on the car is still unburnt fuel. The cane tune from Stillen is likely rich since most can tunes are conservative.

Ok as soon as I put the cupler that came off back together everything is fine. Since that coupler came off, the car ran way to Rich causing the sut. There was zero sut when I picked the car up or half way home at the gas station. The Black sut started coming out when the cupler came off. It runs great now and ran 10lbs boost. All is well. Stillen said not to take off the stock cats so there still on there. Injen cat back exhaust is what I have. Thank everyone for the great help!

Thanks! Such good advice! I will get the new straps also if it comes loose at all again I will do the hairspray trick!

On another note I will upload a video of the custom gauges plus setup and exhaust.

So the shop put these heavy duty clamps on and it solved the problem. No more check engine light and boost is consistent. Getting it tuned next Thursday so will post results.

Those are constant torque clamps; keeps constant clamping during temperature change.
If they start pushing off; then use the T-Bolt clamps.

Have you been Dyno-Tuned yet?

I’m going to PSI in Hillsboro OR on the 7th of June to get a custom Tune and Map and to be put on the Dyno. When that is done I will post all the results. On another note I am not liking the sound of my Injen cat-back exhaust. Really quiet which is fine for some but not for me. My AAM Short tails sounded great but just a little to loud. Anyone know of an exhaust that is just a little less louder then the short tails? Maybe something in between the Injen and AAM Short tails? The shop said they could take the resonator’s out. Maybe that will lively it up a bit.
