sr/ka eporom ECU Programming who's done it

[nab911]

DeviousKA, its a willems eprom programmer and i forget the chip codes.. i got about 10 of them. They were eeproms that were 256kb i think that worked for the ca18.

[deviousKA]

You need some newer flash erasable chips. Most likely all those chips that you have a UV erase type, if they have a little glass window they are. These are simple to read but to burn them you need to have a special light to put them under that erases it clean. They will do the job, but a electronic flash erasable chip is easier to work with and make changes.

Good idea on that zip file, ill do that. Also i have live edit beta 5 ill add as download.

.adr zippedhttp://www.hybridka.com/misc/KA24E_240sx.zip

Live Edit beta 2 (main install)http://www.hybridka.com/misc/liveedit22b2.zip

Live Edit beta 3http://www.hybridka.com/misc/liveedit22b3.zip

Live Edit beta 5http://www.hybridka.com/misc/liveedit22b5.zip

That .adr file will not work with live edit, but the information can easily be transferred over to live edit config file. Ill make one for download later.

No mine are eeproms. No little window. It reads them fine but gives some error like unable to write to address 0x0000 or something. I havnt done it in forever but i figured someone might have an ideo. Ill get some pics one night and load em up here.

[ShadowKnight006]

Wow, thanks for putting all of that up DeviousKa! I think the adapting the ecu with the romulator will be the perfect system for my car since I was already going to incorporate a pc into my car. Now I just have learn this whole tuning thing and build the car. LOL

[deviousKA]

You probably have the setup for the chips incorrect in some way. What is the chip number? There is a variety of ones you can use that take different voltages and procedures to burn (jumper settings, etc.). I have a willem as well, sometimes its tricky to set up.

[nab911]

Thank god you have a willem, ill get you the names of the chips and a pic of my burner and hopefully you can help me set it up right.

[ShadowKnight006]

Quick bump(don't wanna see this topic go by the wayside) and a few questions. A:Have you made an address file for the E yet, DeviousKA? I was trying to do it myself but I still don't understand this stuff enough yet. B: Does anyone know anygood links to resources on ecu tuning in general or for na-to-turbo? I just want to learn and there is no one locally to talk to.

[Arrow]

This really interests me! I think that I'm going to look into it more as this semester comes to an end (I'm at college and away from my 240). And possibly over the summer I might look into a little NA tuning on my 240! It's currently stock, but the first thing that I'm going to do to it when I get back is a BRM exhaust and some work on the intake. I know that it isn't much, but it should be enough to allow for a little change in how the car handles and with adjusting the ECU, I should be able to get a slightly noticable change to take place that will allow me to become more familar with tuning my car so that when all of the turbo parts get collected (probably a year or so down the road), I'll be able to tune the ECU myself and not have to buy an expensive piggy-back or an even more expensive stand-alone! Well, keep the information coming, and thanks for hosting the files devious!!!

[nab911]

I have the address files for every nissan turbo motor but no KA. I was thinking about taking an old ka ecu, desoldering the chip and extending the legs enough to load the old rom into the burner and read the information into a file and see if that would work.. dont see why it wouldnt . Ill get pics of everything up soon and HELL YES do not let this thread die. Last time i tried to get this to work everyone quit.

[SloMoe]

I think you may be getting your terminology wrong. There are 2 types of files used to tune ECUs, .bin files and .adr (address). Bins are the actual dump of the eeprom data from the ECU that contains all the fuel, timing, VQ maps etc. Address files are files used by the ROM editing program eg. Live Edit that tell it where the specific maps are located in the bin files for editing. If you were to hook up your ECU and download the information to a file, that would be considered a bin file. The problem with KA address files is that not many people know the address of certain things like TTP Min and Max, Injector K constants. Fuel timing and VQ maps are pretty easy to locate, but the others arent so easy. Big companies like JWT probably know where they are, but Im pretty sure they dont want to give up that info, as they probably spent a lot of money trying to locate them themselves, and dont want to decrease their share of the ECU tuning market.

[nab911]

Ohh yeah, your right. I forgot about all that. Ill see what i can hunt down and find out around here.

[greazymule]

can live edit be used with the 91+ ecu's?

i know the 91+ require the sr daughterboard be soldered on. what chips should be used? what burner do you guys reccomend and where should we get it?

i have been looking at this and it seems like a good concept once teh bugs get worked out. keep up the good work

[deviousKA]

An address file i put together is zipped a couple posts above.

I am by no means an expert with nissan ecu tuning but try to get more people interested with all the information I have used. Working with the nissan ecus is rather simple once you figure out how they work, and have a variety of files/information to reference and clarify.

I was pleased with the simple rom tuning i did on my 1990 240sx before i swapped to standalone efi. I plan to run the sohc ecu/harness/ka24e in some other vehicle in the future, with modified ecu.

91+ require daughterboard with 2 28 pin chips installed, never worked with one personally.

Just for those of you who dont know and are weary about using Live Edit or Rom Editor. All the things those programs can do can be done in a simple hex editor. You can get a good hex editor like 010 Editor by SweetScape and use the Microsoft Windows calulator in scientific mode to convert hex values to decimal and vise versa. It's not as pretty as Live Edit or Rom Editor, but a lot less buggy (Live Edit) and frustrating (Rom Editor engrish). Address files are usually plain english files that you can refrence to find the locations of the various maps in the bin files using the text editor.

[greazymule]

so you guys got a reccomendation on a chip burner? chips? and where to get them. so your .ADR is legit for the KA24DE? in the past i thought people had used the sr20DET .adr in the absence of a KA one. sweet if there is finally one for the KA.

for a beginner, should i also get a consult box and view all the stats on a laptop or is it unnecessary? thanks

I meant to say a Live Edit config file, sorry. I'll still try to figure it out myself, but I thought if you had one made, I might understand it better. Thanks again for posting everything up and great website by the way.

Theres a config file for live edit.

These .adr and .ini files are not completely finished but good start. These will work well for simple map tuning. Other features simply need to be verified and changed by someone smarter than myself that has the time and tools to tune out all the bugs.

For chips and burners, check out moates.net. I am not affiliated but they have what you need and easy to find/order. I use a deluxe willem burner i got off ebay ($65), it can be setup to do all kinds of different IC. A simple cheaper one can be had for 40-50 bucks.

http://www.moates.net/index.php?cPath=26I use the AT29c256 on my ecu, works great and easy to erase and burn. Also I am using the S4 Aries 28 pin low profile socket.

I have only done this on sohc ecu personally, someone sent me a supposed ka24de .bin and i opened it up with ka24e address file. It appeared to be same, that is all i know.

[ShadowKnight006]

Thanks, I appreciate it. Would you reccomend a chip and burn before getting the romulator?

Trying to keep this thread at the top and a couple questions:

Did the people who had problems with LiveEdit ever get it to work? I'm having the same problem (running XP) and I'd like to fix it because it seems like a higher quality program than the hard to read RomEditor.

Did anyone confirm/deny if the KA24E .adr and .bin's will work for the DE? Also, does anyone know what the difference is between the bins for OBD1 and OBD2 DE's?

[JRL]

Did anyone confirm/deny if the KA24E .adr and .bin's will work for the DE? Also, does anyone know what the difference is between the bins for OBD1 and OBD2 DE's?

I found these by viewing the KA24E ADR file as a word pad document. Then typed the addys (one by one) into my hex editor that came with my programmer. Had both the DE and E stock bin files side by side when comparing.

All of them look the same except:

High/Low Timing

High timing map for the DE is located 0D00, where as the KA24E is located at 0C00

Regular timing is same addy as the KA24E....0800.

VQ looks the same, in terms of high to low patern, it just uses different values.

K? I have no idea

TP Fuel: Same just different/higher values, follows the same pattern though

TP Fire: same as above

RPM Fuel: SameRPM Fire: Same pattern, but, substantially higher numbers

TTP MAX: SameTTP MIN: Same

Accel increas Vol: Same

REV and Max Speed: Not sure, Ill compare my stock DE bin to a well known tuned bin that I have later. Im sure they altered both of these values, just have to find thme....Ill check the tuned DE bin against the KA24E's stock values also. Ill keep you posted.

EDIT: Dont take this as 100% correct. As soon as I have time, Ill test it out on my DE. Still waiting on my 74H00's and gun to arrive.

[JRL]

Just cross refenenced the SR20DET and KA24DE .bin files and they are almost a perfect match....in terms of address location.

Did the same thing....viewed the SR .adr file in word pad....then manually typed in the address in hex editor. I had both files open at the same time side by side (KA vs SR).

The only thing that I do not know if it matches or not is the REV and Speed limit.....and thats only because I dont know what conversion factor to use.

EDIT from what I originally wrote: The first SR rev limit does match the KA24DE addy file heres how.....at addy 5C 5D is 02 and 26 equaling 0226 hex, which equals 550 dec, which when multiplied by 12.5 you get your stock S13 rev limit of 6875....the second rev limit addy's dont match...now on to the speed limit..

EDIT again: The first speed limiter at adress: 0031 (same as SR) on the stock KA24DE bin is 57hex, which is 87dec, this multiplied times 2 equals 174dec....convert that to MPH and you have 108.xx miles per hours....so I would say you can use the SR adr file and probably not run into any problems.

Plus the water temp maps also looked to match, but, Ive heard you really dont need to mess with these.

This may sound to easy but if you want a KA24DE .adr file, just right click the SR .adr file and change the name (which really is pointless cause it will work no matter what you name it).

Although, I still dont understand the multiple speed and rev limits? Anyone care to explain?

I have a willems burner and i know earlier i said i had just black chips... i lied. They have the little glass thing on top So, scince they arent eeproms how am i supposed to burn them?

Buy a UV eraser, erase the data, find a base .bin file for your engine, then burn them normally.

[nab911]

I dont want to have to buy a uv eraser so what are some other options? I have black lights, high power worklights and sun so which of those is best

If your using an odd/even board, aka, an SR20 board that reads two chips at the same time to make one bin file.....then buy two AT29C256's (flash chips) burn your stock .bin file to them and test them out....worst case scenario you waste $20.
