NefMoto

Hi, bare with with me im learning the ropes here  :P

When changing to custom routine, the write up says to change 0x8B3A6 to 0x8B3A9 from F3 F8 F3 8A to DA 88 00 E8. Im just a little confused. Im assuming that this write up was done on a 2.7 because on my 1.8t file the origanal code is different. Do I just replace whats there with the new code?


Thanks everyone!!

Use the script here:

If you can't do it post your file and I'll do it when I have free time

Thanks! ill give that a shot

i got this far.

Any Ideas?

never mind.. i figured it out. i thought all i had to enter was php launch.php

ok so i got every sorted out. error corrected with me7sum and checked with me7checker. all is good.

Now do i need to go into tuner pro and change the settings for rpm thresold, speed thershold etc.?

i tried this already and me7sum finds 3 uncorrectable errors, am i doing something wrong?

i only know of one tool that will correct that chksum correctly and it is not me7sum.

ok, Ill look around

That tool does the wrong thing. It simply nop's the RSA code.. the problem is that NLS modifications are stomping random areas in memory. Lucky its only stomping on the RSA routines.

PLEASE read this post carefully, several times :P

sorry i posted my file above.. would anybody be so very kind to point me in the right direction from this point? is it to much to maybe, just maybe correct my file?

EDIT: just saw nyet post and link, will take a look. Thanks!

ive already had this conversation off this forum.
so is me7sum updated to fix the chks correctly? or is the other still the only option?
it doesnt really matter how it makes it work. it works. other software doesnt.

Care to elaborate? I've posted all the information I have here already. Not a fan of the secret handshake stuff. Leave that to the Euro tuners.


me7sum does things correctly. The NLS script does bad things to the bin.


Disagree strongly on every level.

Bottom line: The NLS script needs to be fixed.

I have no interest in changing me7sum to disable any checksum routines.

At this point, if you can't fix the problem given the information in this post

http://nefariousmotorsports.com/forum/index.php?topic=6308.msg69224#msg69224

... you have no business adding NLS.

It case it wasn't clear from my last post: you don't need ecufix or a checksum program to permanently disable RSA checking in the bin.

meh.
still doesnt make my original point invalid. the current file the op has will cause a chksum fault.

op, this will work. even though its "wrong".

Thank you so much.

Yes, because the NLS script compromised the RSA checking functions in the bin. Why should me7sum DISABLE RSA checksumming?

as a quick patch, it works.
there are LOADS of softwares and patches that dont work correctly and 100% of the time that make their way to mainstream (not just ecu related).
its a patch. it works. it will save this guys car from being dead randomly one day when he goes to start it.
i didnt see you posting telling the guy his current file wouldnt work?

its great we (you) know what the problem is. but currently there is no other solution. this is a solution be it ideal or not.

That file gives me a no start...

I successfully wrote on the community stg 1 file and it is working

I used the script and got an no-start too. Weird thing was it started twice but failed on the third start for me. I did the first two starts and called it good only to have it no-start at the gas station. Luckily I always carry a KKL cable and netbook with Nefmoto on it in the trunk. Pissed off the guy behind me waiting for the pump though...

I did the same as you and found a bin with anti-lag already done and worked from there. Not ideal but it works for me. That said, I hardly use it anyhow. I'm sure its going to coat my O2 sensor in carbon eventually. I do like the NLS however. Use that quite often now that I've learned to override the natural tendency to lift off the gas.

The community stg 1 doesn't have it added. I metioned over in that thread if anyone would like to add it to the file.

I have some kind of mental issue I've always wanted antilag but my last car was a diesel. I was able to get launch contorl working but nothing close to Antilag. I said to myself if I ever take the plunge to a gas car, AL and nls is the first thing I'm doing. I don't really like the n2mb wot box I'd rather have it in the tune....

the file you posted earlier has a few weird changes inside of it. maybe thats why it doesnt start.

Probably, im at home now so I can go through it a little easier now. im going to try to redo it. <

Edit: I think I have to choose my settings in tunerpro first, save it, check it, then add the script. That make any sense or no

Sorry about my confusion on that. Wish I could help but the working AL/NLS bin I have is 032HN.

Nothing wrong with wanting AL. Hell, it is pretty neat in and of itself. Hope you sort out a solution.

ok so I set my speed and rpm thresholds etc. me7sumed it and it corrected the errors. me7check no errors found. Then ran the launch.php, and me7sumed the output file. 6 errors were found and it fixed them all. me7checked it, now I have no errors at all. Seems promising  ;D

Will flash in a bit and see if it starts. Ill attach it if anyone wants to look.

If the script munged the RSA function no amount of checksumming will fix anything unless you no op out the RSA checking calls.

Wrote to file to ecu and it starts!!

Little to late in the neighbourhood to see how it works but will check first thing in the morning

it will no start and chksum fault.

Really? I thought I had it?

You don't have it. It's a bug with the address the routine uses. No amount of checksumming will prevent the issue when the RSA signature check fails.

It started this morning... Drove it an hour to work, shut it off, still starts. Antilag and nls is working. Is there any point in leaving this file on to see if it ever does show a problem or is that just a waste of time?

Edit:Nvm, went to go try again and sure enough. No start

Dude, this type of error can take weeks to happen. If you run the file without no opping the rsa like Nyet and Kompressed explained, you will find yourself in a no start situation. Maybe a brick. You should be prepared to perform a boot mode flash anywhere you drive this file.

Ok, I wasn't sure if it would show up on 2 starts or 2 weeks thanks. I'll be more careful now

From what I'm gathering I have to change the location of the nls code/ buy ecufix or find some willing to check it. I would like to learn how to do this myself, I have learned quite abit so far and I appreciate everyone's help and patience.

If someone's willing to check it, it would get me out of a tight spot. But I would still try to fix it properly regardless

current file

Is there anything to read to teach me about what the rsa is/does, is it possbile to modify the code to no-op it manually? Do i use a hex editor?

Again, that is not the solution. The solution is to make sure the NLS code doesn't stomp on RAM locations used by the ECU, or don't use NLS.

In all honesty, if you don't know what the NLS patch does (and you can't implement one yourself), you don't have any business hacking the ECU ASM.

That's what I'm referring to, I'm sorry. I feel really behind here but I don't even know where to start by looking at that.

Seriously, stay away from NLS until the author fixes the script (or preferably until you know enough about ASM hacking to do it yourself).

It can't possibly be that important to you; you should be learning other things right now anyway.

Ok I understand. I won't bother touching it right now.  I would still like to have it,  but I would have to get it done by somebody who knows what their doing...

Alternately, you can cross flash with a file that is known good that will take the NLS patch w/o side effects.

I'll have to do some reading tonight

chks ok.

Thank you very much

I've been trying to get the custom code functioning on my file but can only get NLS to work so far, comparing my file to this one I spotted something odd. here is my progress so far http://nefariousmotorsports.com/forum/index.php?topic=3349.msg88913#msg88913 (http://nefariousmotorsports.com/forum/index.php?topic=3349.msg88913#msg88913)
What is this line of code @17E00 for, above the variables for the LC+NLS @17E20?

Thanks
