NIStune In RB25det

[Nissan2367]

Alright i know ill prob get abused and verbally assulted for this but i am so damn confused! For the past 3-4 hours i have been searching this forum, and reading everything on the NIStune website to figure out what would be best for my setup. Now i was going to go with AEM or Power FC but i dont have the money for it and from teh research i have done found out NIStune is very user freindly and would work just fine for me.Now i know the only board that works with the RB25 is the Type 4 Board (for ER34 Skyline)Ill be the FIRST to tell you i know NOTHING about tuning and electrical for engines. Evan can second that for me! Basicly i can build the engine just not tune it.When researching what i need and what i need to buy i got super confused so i am hoping someone can clear this up for me. Also when it comes to installing the board i wont even try it so i am hoping i can send it out and have that done. (CarlH please step in with help)I have a deal with a local shop here that wants to start using NIStune and wants to use the software and see how it works so he is willing to tune my car for free for however long it takes to tune it. Like i said i have no idea what i am doing!My setup is fairly stock right now but within the next 2-3 months ill be adding a H1C turbo, 1000cc Injectors and converting over to E85 so i need to get the tuning part figured out first!Like i said any help would be awesome even if its listing threads for me to read (but i bet i have read more then half of them)Thanks Guys i dont mean to sound like such an idiot!!!

So whats your Question ?? lol.

if you don't know anything about tunning then don't try to tune it. and as far as NISTUNE goes its not available for the rb25 except for the r34 meaning it wont work with ours.. um something about the wireharness and being from a r33.. I was reading about it and thought about getting NISTUNE also, but its not going to be available for the r33 until mid summer from what dude (the guy doing the tunning) told me!! so don't know what to tell you!! you mind as well save some extra and buy a PFC.

i think they use a re pinned z32 or rb20 computer.

[Kansei240sx]

Dont use an RB20 ecu for a 25.

Use a VG30DE/TT Ecu from a 300zx, install nistune chip to ecu, re-pin a few wires on the main blue plug to the ECU. Done.

Nistune > Overpriced EMS's that dont even have factory maps to fall back on.

you are correct about the Z32 ecu. But you will not be able to run the rb25 . I already checked and been talking with the guys at the other forums. do your H.W gtr forums and gtr skyline australia! there's more info there! but last time i checked it will ONLY be available during the SUMMER!! for the rb25 that is!

[Kansei240sx]

If you lurked around here more, you'd know that there are people already running RB25's with UNCHIPPED stock z32 ecu's. I've already got nistune on a VG30DETT ecu on my RB25 that works. I just dont have it running due to turbo upgrade etc....

[Nissan2367]

Damn the RB25! Haha I guess ill ether save and buy a used Power FC or ill just get the 300zx TT ecu and repin. For some reson i am going lean in upper rpm and rich down low so i figured a good tune would help but i guess that will just have to wait.Thanks for the info guys ill keep lurking around to find more

[mattleegee]

just a 300zx/z32 with vvt that is all that matters you dont need TT

Learn something new everyday here! thx.. so a stock z32 ecu hunh? plug and play? is that better than the stock rb25ecu??

thanks

No you will have to repin the connector... but i am not sure how involved that is... That and like they said you will need one that has VVT

[meet07]

I did a lil research on nistune and my ecu. I have a 94 series 1 and looked into getting a board. My part number says that it is a type-6 board?? so I personally have a 300zx non-turbo ecu. i'll be ordering my nistune board up this week or next. My safc went out on me. There is a harness that you can use to keep the factory harness untouched. I have to wait till i get home to post the link. I beleive it was around 150 bucks.

I guess that I need to remove mine since it "doesn't work".



Z32 ecu (NA or TT) + Type 2 board. BAM!

[Nissan2367]

^Nice^Anyway i would love that link... i dont want to have to repin so that harness would be perfect! Then ill look into getting a z32 ecu so i can get nistune! I am pumped cuz my car NEEDS a tune asap!

[PorkChopExpress]

id check on how many you have to re pin, i think i read it was only a few.btw i just got done installing the nistune board in mine, wasnt that bad.

so far its been great!! really like it. totally worth it. BUY ONE!!!!

[Nissan2367]

Sounds good to me! I plan on using it for sure! i dont have the money to buy a FC or AEM. Can anyone confirm what year z32 ecu i should look for? My friend has one out of a 90-96 non turbo m/t. also can anyone confirm what needs to be repined... maybe ill save the cost of the conversion harness and just repin!

[l0nestar]

If memory serves, repin is 4 or 5 wires. I posted the pin changes here before - they are on the NisTune site. I believe under an FAQ.

Any Z32 ecu should work - you are updating the code on the ecu. Doesn't matter what the original rom says, your changing it, remember . pin-outs are the same.

Awesome thanks for the help! I am wiring stupid! Ill get the ecu and go back on thier website to see what i can find on the repin.

MEET07:If you have the link for the conversion harness let me know i may just buy that and call it done!

Also CarlH feel free to jump in... I am wondering who can install this chip for me. i dont even come close to trusting myself to install the chip myself! Thanks Guys

[Carl H]

make sure you get an 'early' z32 ecu as its 8-bit and is easily chippable...the 16bit version can be nistuned now but wasnt a few months ago.as far as installation goes i can install any nistune board and have proper tools to do so...there is a reason that i have a 250$ desoldering iron.

Carl,

Do you know approximately when the switch was from 8 to 16-bit ecu's?

[Carl H]

around the same time they made the major engine changes so late 93- early 94.hard to pinpoint...best bet is to just pop open the ecu and look...if you see a 28pin eprom then its an 8bit if you just see a header then its a 16bit.

[meet07]

Its made by field one. $144.00 us dollars is what there asking. Here is the link.

[meet07]

This is what the 8-bit looks like. Thanks Carl H. Ive been back and forth with chuck over at Z sport trying to figure out if I had the eairly or late model z32 ecu.

[Nissan2367]

Sweet thanks guys for all the info! i am going to start looking for an ECU now. i cant find anything reasonable right now but ill keep watching! Ill prob send the ecu to you to put the chip in Carl. How much do you charge to do that?

Reading the info on that harness it just says its an extension not a conversion harness... I was thinking it was a plug play from rb25 to z32

[Carl H]

please email me for info.i try to keep buisness off the boards.

How is the 'factory' map going to work when you have redefined the load points (N01-N20) and recalibrated the airflow curve of the MAF????

[meet07]

it should be just as easy as uploading the bin into the nistune software. Thats how it was on my honda.

[240z4u]

Hey sally, you should repin that harness yourself. You are scared of wiring for no real reason. Hell, you don't even get your hands dirty most of the time!

Also, if your FPR is still leaking email me for a link to some kickass thread sealer goo that I got.

Evan

[Nissan2367]

Hahaha a**!!! I am going to just repin it its a waste of money to get that harness!And it leaks sometime, i used thread tape but when we work on my manifold and dp we can use some of that! What is the link?

[Nissan2367]

Just for anyone looking... I found the repin threadhttp://forums.nicoclub.com/zerothread?id=359056It looks like that harness would be a good idea just so i dont need to cut up my oem harness.now all i need is the pin readout for the z32 ecu!
