Also to add a comment for anyone in this process, make sure to do a basic "tune up"/check! Clean filters, clean spark plugs, clean oil, vacuum leaks, and the such. Some of these can cause a drastic impact when tuning. Take the time to prep before proceeding.
Thank you so much for this video. I have a very similar setup with the Hx35 and front mount but with 650cc injectors. Z has been just waiting patiently for some time now lol
@@TheZGarage yes Nistune is connecting to my computer perfectly fine. The LEDs only flash when the key is in the ON position. Both the red and green light flash once, pause, then twice, pause, then 3 times, pause, then 4 times, pause, then 5 times. And I used the map for my exact ECU. My ECU is an 88 but my car is a 84.
It's just cranking over and not starting? Do you smell fuel in the exhaust? You could try to spray a bit of starting fluid in the intake and see if that gets it to go. It would help narrow it down
It's actually closer to 600 bucks since you have to buy the license and consult cable. Wish I would have known this before buying a used nistune ECU on fb
And add another 100 to have them install it for you if you don't want to do it. The gold box at that point, is about the same price. Probably gonna sell this thing
If you are still na then you use the vg30e. If you are now NA2t then you use the vg30et. The t is for turbo and the ignition timing is different to keep it safe when running a turbo
It's been a while, but I do remember connectivity issues with my nistune. I'm not sure a good fix, but I contacted nistune directly for some of my issues and they were always really helpful so I would check out their site and email them. They usually get back to you super fast too
I noticed you said how you have to “burn into the ECU” to make the changes permanent and save for the next time you go to start your car. Is there anyway to overwrite a previous burn if you wish to tune things differently in the future?
When I say burn it into the ecu, basically that means it's saved to the ecu chip and even if you turn the car off and unplug the laptop, your tune will be there. If you want to change the tune in the future, just load your tune, set it up however you want to, and then burn it again. It will just save the new tune in place of the old one. I only warn about being careful to hit the burn button because if you don't save a good tune to your laptop and you accidentally burn a bad tune to it, now you don't have a good tune to reference and you'll have to go back and make it all over again. So make sure to save all the versions of your tune, especially when you make good progress
Very high numbers are lean. I'm assuming it's that way for some sort of fine tuning. So about 190 and up to 255 are lean and then increasing it brings it back to 0 and then will go up to around 25-30 in the most rich parts of the map. I think it's just how the nistune software works
If you download the rom file pack from the nistune website it should have all the bin files for each z31 ecu. If you don't see it, I would contact nistune themselves and ask if they have it or if another bin file is compatible.
It depends on the year but you need to modify the ecu slightly to bring it from a 7v to a 5v system. Then it's just selecting the z32 maf in nistune and you're good to go
I know its old but do you know if I can use nistune type 1 on my 1984 turbo? I emailed them directly because it said 84na & 85-86 on nistune website but they weren't sure and said probably not , but don't see why. Hoping you would know something
Sorry it took so long to get back to you. CZcams didn't tell me you had commented. I believe early 84 ecus were different than later styles. This is probably why they think it's not compatible with your ecu. I recommend getting a newer ecu anyways as the 84 ecus are known to be unreliable and you don't want to modify something with issues because you'll spend a lot of time and money diagnosing something that's just bad to start with
@@TheZGarage no worries brother thanks for the reply, so if I buy a 86 turbo ecu I just plug n play? Or does the ecu I get have to be from one with a digital dash or does that not matter
Would u happen to kno what kinda of power can u make using nistune on a 85 NA I've been considering an LS swap but I would hate to change out VG. Lol I'm so confused in what to do :( Click on my channel to see my Z31
Na is pretty limited in power. You'd get better power gains with cams than a tune. If you really want power, do the NA2t. It's the cheapest option and the vg can make a lot of hp before having to be built
You can get all the stock parts for less than about $700 from someone with a parts car. Upgrading stuff to make more Powe will cost a bit more with an intercooler, piping, etc. Probably 1k-1.2 for a good build if you get everything right the first try

I had to watch this video like a 100 times to finally understand ..but im finally tweaking the numbers now, thanks man good video 👍🏾
Hell yeah man, I'm a little late to the z31 world but your videos make it easy to catch up
Let me know if you have any questions! I'm happy to help!
@@TheZGarage I believe I know you from Z31 300zx Drivers and I'm sure you've seen me around there haha
Thanks for showing the timing map! When I get done wiring my harness and start up the car its going to be a lot of getting it off the ground!
I'm about to drop a turbo engine in my z soon so this will be helpful
Glad it'll help!
Don't touch the timing map
Me staring at the timing map: *MCM chants intensify* "PAGE UP, PAGE UP PAGE UP!"
Page up is more boost!
@@TheZGarage yeah in the particular software they were using, it is. I was just making a joke because you said not to touch the ignition table.
Hi
Very helpful video evan in 2023 :) but u forgot to show how to set up a launch control
Thank you so much for this video. I have a very similar setup with the Hx35 and front mount but with 650cc injectors. Z has been just waiting patiently for some time now lol
It'll be a blast once it's done! Good luck!
@@TheZGarage I still can’t get the damn thing to run.
Is nistune connecting properly? Do the led's flash when you turn it on and then turn off? Did you load the map for your year correctly?
@@TheZGarage yes Nistune is connecting to my computer perfectly fine. The LEDs only flash when the key is in the ON position.

@@zhongxina2793 did you end up selling nistune
hey quick question, if in turbo my n/a 1984, (which has a na manual 1984 ecu) should i use the 1984 vg30et or the 1984 vg30e? thanks!
If you are still na then you use the vg30e. If you are now NA2t then you use the vg30et. The t is for turbo and the ignition timing is different to keep it safe when running a turbo
Thank you so much!
Great video! Have you ever seen an "out of sync" or data synchronization mismatch" type error when trying to burn? Any help would be appreciated!

@@TheZGarage ahhh I can see why you stress it. Thanks so much for your speedy reply my dude!
Wait, in your tune the "leaner" fuel map cells were bigger numbers, and the richer cells were low (lots of 0s). How does that work??
Very high numbers are lean. I'm assuming it's that way for some sort of fine tuning. So about 190 and up to 255 are lean and then increasing it brings it back to 0 and then will go up to around 25-30 in the most rich parts of the map. I think it's just how the nistune software works
i had a quick question i have a 84 nistune only has the 86 up how would i do to work that out?
If you download the rom file pack from the nistune website it should have all the bin files for each z31 ecu. If you don't see it, I would contact nistune themselves and ask if they have it or if another bin file is compatible.
@@TheZGarage ok thank so much this really does help out thank you again 🙏🏽
Was that all you had to do to utilize a Z32 MAF or was there a separate video involving that?
It depends on the year but you need to modify the ecu slightly to bring it from a 7v to a 5v system. Then it's just selecting the z32 maf in nistune and you're good to go

@@jokernasty3674 nistune told me for my 85T it’s best to run a 87NA or 88 with high impedance injectors/dropping resistor
@@zane7433 nice, thanks alot appreciate it bro
U mentioned in a video u stay in New Mexico believe?
Yes I am. I'm in Albuquerque at the moment
Did you buy a license to tune your own car? I bought nistune and installed it to realize I can not change anything.
I bought a license. Honestly though it's been so long I can't remember where you have to enter it in to activate anything.
@@TheZGarage it's right when you open nistune on the computer, it ask for a key.
Did you put one in?
@@TheZGarage yes I did
Are you sure you're connected to the ecu? Can you see live data?
Would u happen to kno what kinda of power can u make using nistune on a 85 NA
I've been considering an LS swap but I would hate to change out VG. Lol I'm so confused in what to do :(

@@TheZGarage whats an estimated value to drop in a turbo? What did u spend of u dnt mind me asking?!
You can get all the stock parts for less than about $700 from someone with a parts car. Upgrading stuff to make more Powe will cost a bit more with an intercooler, piping, etc. Probably 1k-1.2 for a good build if you get everything right the first try
Going to have to look into that.. thanx
When u have a chance check out my Z on my channel.
Did u install nistune yourself?
