ROM Tuning Database

[WDRacing]

I was thinking...

With all the talk lately about who to go through and how much so and so charges. The process is actually NOT that difficult to do on your own. The hardest part is soldering the boards and that can be done at almost any electronic repair shop for like $30. What we lack are functional maps and what setups they work for.

Might as well get a database together right?

I know we have a couple guys in here that would love to do a "How To" writeup...right guys? Lets make this happen and I'll keep it cleaned up so we can discuss various tunes and troubleshooting in a separate thread but we can link back and forth etc.

Sound Good?

[GTR PrYdE]

sweet, I'll get the emance rom so we can see how NOT to tune.

[WDRacing]

Unless you signed a disclaimer, I don't see a problem with posting ANYONE's maps

[esahuque]

Sweet, ive been waiting for a write up like that. Ive been wanting to do it myself but never realy knew where to start.

[Chris28]

This thread is going to be awesome! I remember someone saying that they have a few maps and they were just waiting on a cable or something to actually burn the roms, but I don't recall if it was an old thread that I was reading while researching or a recent thread. Anyways this is going to help me out a lot!

[s14derrick]

maybe we can use this and also have like someone be the official nico rom tuner or something

[GTR PrYdE]

Question WD-

Are complete maps going to get posted up so someone can burn chips and be "tuned" or is this going to be a guide for tuning?

[WDRacing]

I'd like both, maps and guide. When we get a few maps put up I'll make a new thread that will have JUST the maps.

I have a few tunes but, they are all for the sohc. There is not a whole lot to rom tuning like WD said. For the single cam tuning the hardest part is desoldering the stock chip. For dohc all you need is a daughter board and your good to go.

Rom editor is the easiest to use imo.

All this info is nicely bundled thanks to Hybridka and the members on that forum.

Rom Editor download, English and Japanese versions. Both require asian text support to display properly on PC.

You need asian/japanese text support to view the program properly.

[quote=""if0rg0t""]You need asian/japanese text support to view the program properly.

I figured it out, go to control panel -> regional and language options. Then click on the advanced tab and in the first pull down box, it will say something like "Language for Non-Unicode programs" in blue at the top. From the pull down list select Japanese. Click ok and it will then say you need to restart your computer, restart it and the program should look like the picture. It worked for me and I hope it will for you guys having problems.

First of all, you want to open the .adr file. The .adr file contains the addresses, of the data, and its units etc... Click on the 'Are crowded as reading address file', and select the appropriate .adr file.



Then, select the .bin file you want to edit. Click on 'Load(BIN)'.



Then, you are presented with a spreadsheet which contains the data in the .bin file. Towards the upper part of the window you will see several tabs as highlighted by the green rectangle below:



Only 2 rows of tabs are visible. Actually, there are 3 rows. They are as follows:1. [Hi octane fuel map, Hi octan lg-time map]2. [Add.map 4, Add.map 5, Add.map 6, Add.map 7, Add.map 8, Global]3. [Low octane fuel map, Low octane lg-time map, VQ map, Add.map 1, Add.map 2, Add.map 3]

However, they are displayed a bit wierd. Since only two rows are visible at a time, if you click on a tab, the rows switch around. If you could see all 3 rows, it would look like this:



But, only the rows within the blue rounded rectangle are visible. * If you click on a tab on the first row, the entire first row will go to the bottom, and the bottom two rows will shift up - and since the botom row is not visible, it will dissapear.* If you click on a tab on the second row, it will switch places with the third row. In other words, the second row will dissapear, and the bottom (hidden) row will take its place.

Now, let's go to the Hi octane fuel map.

* The stuff in the black circles correspond to each other. The left one contains the starting address of each row. e.g. 0100 means that the cell right next to it (first row, first column) is at address 0100 in the .bin file. Each subsequent cell on that row has address 0101, 0102, 0103, etc ...The right circle contains meaningful labels for each row. In this case, each row corresponds to a certain RPM. So, the 4th row in the RPM column corresponds to the 4th row in the table (in this case, 160, or 1600 RPM).

* The stuff in the green circles correspond to each other. The upper one just numbers the columns, 0 to 15 (15 = F in hex). The bottom one contains the relavent labels for each column. These are the TP values for each column.

* The 'Boost' entry (with a yellow line thru it) is meaningless, and you should ignore it. It is an entry of calculated values (using TP and other stuff), which is misleading. Don't worry about this, is doesn't have anything to do with the data in the .bin file.

In order to open a map to look at it you need to get a adress file and a base rom. Both you can download from hybridka.com

Here is a good read on basic nissan tuning: (this will make your head spin the first time you read it )

Enough spoon feeding you guys for tonight.

[eazye2000]

I've got some good stuff to contribute. I will post up some screen shots as well, so that can hopefully clear up any confusion that will come after my trying to explain something. Yeah, it's terrible..

Welding some pipes up on the car this evening. I will clear this post, and put everything in here as to not clutter things up.

i can host ROMs if you guys need a server for that.

[Lopin18]

OMG Do thisssssssssssss, im like 1 week away from tunning my ka24e with a stanza ecu. Updateeeeee

[WDRacing]

i can host ROMs if you guys need a server for that.

We can host anything pretty much...if anyone needs anything hosted just send it to me. I only say this because if it's hosted on OUR server it won't become a red X at some point.

WD

[Chris28]

So who has tunes? If this is a database then will it at some point include base tune files ready to be modified and sent to a chip burner?

[WDRacing]

I'd love for people to upload tunes here. Then I could build a huge database and organize it so it's easy to navigate etc.

Basically I'm just waiting on YOU GUYZ to post up your tunes.

[Chris28]

Well then whoever has some tunes POST THEM!!! Haha all I need to complete my setup is a tune, and I don't feel like dropping 500 washingtons on something I can do myself.

[WDRacing]

I hear good things about EFI Specialists...$305 isn't bad either. They offer specific tunes as well as custom. I'm not vouching for their work, but I have yet to hear anything bad about them.

WD

[Razi]

So, we would just need a daugtherboard (i.e. Nistune?) so we can edit our ROMS in our ECU, and we download a ROM for a setup that is like ours, we load it up, start the car and maybe make a few changes (if we know how) and get the car running?

[nelson8708]

Thats more less it.

All i have are a couple tunes for the single cam but, i will send them to you (WD) when i get a chance. I've got a crazy weekend coming up with midterm tests, trip to Street Life Tour in Ohio, and i need to install a new water pump in my civic before she lets go and the timing belt goes with it.

[Lopin18]

yesterday i met with 2 tuners, one is a genius here, a truly genious, also another one that works on skylines, audi tt, datsun etc... you get the point, another truly master of tuning, ill be getting my car tuned by both so ill get that tune up here for a change.

[S13FX]

Well Nelson pretty much posted what I wanted to post.

So let me give you guys another option.

http://www.nistune.com/

I got it for my Z and its ****in awesome, at first it can be a little over whelming cause of all the little crazy options you have but once you get used to it your golden. And Real time tuning is ****in amazing.

This is like Bikirom tuning but specifically for Nissan and works with all stock sensors.

[Razi]

I've read that link you gave us.http://eccs.hybridka.com/viewtopic.php?f=19&t=47And I've read the Basic Tuning Equipment section, and so far as I understand, you just need an EPROM that you can continue to write to (reusable) and you can edit and place tuned .bin files into em and not need a daugtherboard for any of this?

Just an EPROM, EPROM emulator, programs and maybe a cable to communicate with your ECU?

Would a Consult cable like the ones sold by Enthalpy, be able to write to the EPROM? I haven't used their program before but I remember seeing a "Dump ROM" tab in their program.

[scheffler]

hey I have a emance tune that i could probly post. But my ? is do you guys want it. My car runs great with it 15psi pulls hard to readline AFR are a little rich like 11, but i know that emance has a put a bad taste in every ones mouth so you guys might not even want it. But anyway I think that this is a great idea so at least I can give this a little bump. So just let me know if you guys want the tune.

[neverlift]

sure post it! that way devious can let everyone know if it is stolen....

dont forget to post the setup you run it on

[nelson8708]

sure post it! that way devious can let everyone know if it is stolen....

Yeah, i bought a tune from him a while back and it was gabe's n/a stage 3 tune. Didnt get my money back...Emance=fail

[scheffler]

ok I will post it might take a day or two.

Funny thing is it was originaly a enthalpy tune that wasn't working and emance is local in san diego so i took it to him and he looked at the tune and said oh yeah i know whats wrong changed some **** on the maps and BAM my **** was good.

SO i will post it up.

[2FourTee]

So let me give you guys another option.

http://www.nistune.com/

I've been running Nistune since May, and I absolutely love it. Very easy for a novice like me to figure out.

[nelson8708]

Once i get serious (400+hp) i will pick up nistune. Awsome realtime tuning for a great price too.

[scheffler]

Ok i am still working on geting that tune. Painting my car has taken longer than expected.So basicly bump.

for other people to post up tunes let get this going.
