NefMoto

Unable to read the Vast tune on my car using NefMoto (likely due to them blocking it). I resorted to pulling the bin using Galletto with the ECU in Bootmode. I successfully read the ECU and was given a bin file which I subsequently attempted flashing directly to a spare ECU using NefMoto.

With the "successfully" flashed spare ECU the car will not start even once. I even attempted correcting the checksums using the mtx checksum plugin and flashing again to the same demise.

Running ME7Check on the original pulled bin gives a warning: "modified all_param_start = 808000 found at 808030" but claims no "errors" were found.

Attached is the bin pulled directly from my VAST tuned ECU in boot mode.

EDIT: Simply opening and saving the bin in TunerPro to correct the checksums results in ME7Check claiming their is a checksum error.
EDIT2: I think it's related to Vast trying block kwp2000 interaction. I just need to figure out how to reverse it.

To those that didn't read the brief summary above:
This is not for public flashing and is locked to my EEPROM, has hidden maps, and has tamper protection that causes reset loops

What is your intent?

The emissions is not correctly coded out. My car wont pass readiness. A quick google search will show that I'm not the only one with a VAST tuned S4 that has the emissions messed up. If worst comes to worst I'll just use as much information as I can from the VAST tune and apply to my own custom tune. I'd much rather keep the tune I paid for though.

Then why post vast's tune on an open forum like this where it's very likely that noobs will download and use the file, possibly even sell it?

If you read the bold red text you'd know that this bin is not flashable. I posted the bin in hopes that a more senior member could look at it for me or tell me how to fix it. I didn't think it was a big deal considering it's for an unspecified stage 3 setup (mine). And I don't think VAST will mind.

Unfortunately, the current climate is that tuners DO mind.

Sadly, if you want to do something simple like remove rear O2 or change the rev limit on a tuned file that you paid for, you are boned.

The most "accepted" way is to rewrite the whole thing from scratch.

If you aren't interested in spending the time and effort (it is considerable), your best bet would be to find somebody you trust who can tune the car AND give you ownership of the resulting bin such that he is ok with you modifying it later.

The problem is when doing a difference check between the vast bin and a stock bin their are an unbelievable amount of unmapped differences. I "quickly" tried to build my own tune using some information obtained from the vast tune and ended up with something not so great.

I have attempted to get Tony's Base stage 3 tune working by migrating the fueling and MAF data from the VAST tune but I always end up with the idle bouncing between 900 and 1000. a rising and falling cycle every second or so one might say. Any ideas?

Also feel free to remove the bin from my original post.

I DLed the file and corrected the checksums using another checksum correcter. Should I PM you with it or will I get smited for posting it up?..I dont want to be a dick.

If you pm'd it to me. I would be eternally grateful.

I think I need a regular email for you. I cant figure out how to attach a file to the PM..

I sent you a PM

back at ya now

ME7Check claims there is a checksum error. It seems "correcting" the checksums or doing anything with the original bin (including flashing with nefmoto) causes some sort of checksum error.

Can someone elaborate on the "warning: modified all_param_start = 808000 found at 808030" that ME7Check spits out?

Summary:
Checking the original file shows no checksum errors. Attempting to correct them actually causes a checksum error and flashing with nefmoto causes the car to not start and spit out the typical checksum DTC "decoding not licensed" error

Are you serious? Vast is no longer in business. This guy has no recourse other than to post asking for assistance. There is no other way for him to sort this out. If the tuner was still in business (I'm sure it was assumed they would be when he bought the file) he could go to them. If that were the case, I'd agree that he should go to them first. This isn't the case. As long as he's not advocating copying the file (which to be honest I doubt anyone who blindly downloads it could get to work anyway), or listing the required components to use the file, what's the problem?

If you have nothing helpful to say, go away. I've seen your posts, and this is just more of the same.

Don't worry about being smited, very few people can please everybody. I'm sure I'll get smited for these comments, but I don't see the issue with offering assistance to someone with a legitimate request.

BerkleyJ:

I'm not sure how much luck you're going to have with modifying that file. I'm looking at it now, but I've seen a few vast files, none of which looked like that.

Try this. It's your file with standard m-box offsets patched in, and the checksums corrected. If that flashes, modify from there.

Flashed. Getting the same issue. Car will not start even once.

NefMoto DTCs:

P1602 Decoding not licensed
Status: 0x22

This isn't related to the "RequestUpload disabled" stuff is it? Even if not, how to you reverse that? Someone has to know what tuners change in order to block reading the ecu.

1602 is terminal 30 power supply too low. Not really relevant here, should be able to clear it and have it not come back. Looks like you're starting from scratch. I wouldn't anticipate porting the tune over either, the maps aren't in the right places.

Weird. Kind of a shame I'll just have to throw it away. I don't think I know enough or have the patience to tune from scratch. I'll probably end up dumping cash into EPL or JFonz pocket.

Thanks for the help though

why don't you try to flash a stock file to your car just to see what happens with getting the engine started and whatnot.

I have the original vast tuned ecu which starts the car fine and is my DD. I do all my experimenting on a spare ecu.

Did you clone the EEprom to the spare ECU too?

No, I didn't?

Yea, it's locked to the EEPROM. Simple as that.

i was helping him last night we got his LTFT down to the right numbers also a steady idle just have to adjust KFMLDMX  for the maf signal to high issue

we started with the nefmoto file
Adjusted Tvub to his ev14 550cc injectors
Lowered Temin to .200
Did some calculations and krkte is at 0.04995
Copied the rs4 mlfhm table

Thanks for the heads up phila_dot

Read the eeprom from the vast ecu and wrote it to my spare, then flashed the original vast bin and the car works. So I have successfully cloned my vast ecu. How do I go about fixing the emissions its seems whatever I do to the vast bin jacks it up and the ecu goes wonky and becomes hard to connect to, similar to bad checksums.


Did you actually get the maf scaled, send me the bin. I'd still like to have a base tune I can play with even if I get the Vast tune fixed.

;D

This is what I've been trying to tell you.

Thanks for the heads up on the EEPROM, now how do I go about getting the emissions fixed. Whenever I do anything it seems to jack up the bin.

Have you tried the file I posted with the eeprom cloned? If it works, you can edit from there.

I told you I would help once you got the car started.

I'm not assisting in making this freeware, but I will help you get what is right in your situation.

Yeah, I tried it. It starts once but then starts acting up like the checksums are bad or something. That vast tune has got all kinds of weird going on.

Hey berkley, while I don't think posting the vast file was a bad idea, I do think leaving the eeprom up is. With that anyone can use your file, which is what everyone was afraid of.

Hope you get it sorted!

After I get all this sorted a mod can come through and remove all the attachments

No. Mods are not your personal janitors.

haha, Is there even a way for me to remove them?

The "modify" link on the top left of each of your posts

Oh... I'm dumb. I was just using the edit icon...

I removed the eeprom. I'll remove the rest later.


Further instructions, please ;D I'm kinda stuck.

EDIT:

Summary now: If I make any changes to the original vast file I get a checksum error I cant get rid of. If I make changes to the vastfixed.bin ddillenger posted I can correct the checksums. So here's what I did.
 
1. Modified and checksum corrected ddillenger's vastfixed.bin
2. Flashed it in bootmode.
2. Car started once but did not appear to reflect the changes i made.
3. Car would not start a second time
4. I proceeded to pull the bin in bootmode.
5. ME7Check the pulled bin and there were 3 errors
6. Opened the bin in TunerPro and the changes I had made were reversed? (I made the changes again)
7. Corrected the checksums again.
8. Flashed again.
9. Car started only once again without reflecting the changes I made
10. Pulled the bin in bootmode again
11. ME7Check shows the 3 errors AGAIN (and TunerPro shows that the changes I made were reversed AGAIN)

This vast tune is something weird

I'll send you a message when I get home.

Why not just make a stockish tune that will pass emissions and then once you have your emissions test done put the vast tune back.

Also from what I recall, VAST was using/licensing APR's technology to tune cars which is why their files are not editable. At least their later files were I'm sure.

I actually used your stage 2++ file completely un-altered shortly after starting this thread and was able to pass inspection. Afterwards, I had to change my oil because of how rich it was running just for the short drive to the inspection station. It would be nice just to have the VAST tune fixed, but at least I'm not in a bind now. phila_dot was looking at the VAST file and by the sounds of it, it seems pretty tamper proof. I really need to get a AFR gauge setup before I do any of my own tuning, but I'm pretty tight on cash right now and have a laundry list of other things that need done just for my S4.

That makes no sense, unless of course you kept your larger injectors with the stock scaling in my 2++ file and I can see you basically flooding the motor :P

Either way, it is unfortunate that you are stuck with software that you cannot edit and the company no longer exists to support you.  Good luck either way!

Abandonware at its finest.

Lets hope ME7L, ME7Check, and Nefmoto flasher don't fall into this black hole :/

If Tony's truly done, do you think he'd be amenable to selling the source code? I bet we could all throw in to bring the price down to a reasonable level.

I only ask because I shudder every time you say that.

Agreed!

Thats exactly what I did. I don't have any other injectors to swap in. I was rather surprised at how well it ran, I guess the larger MAF balanced out the larger injectors well enough to drive. It seemed to handle it all okay in the end, but I would rather not do it again.

Im just gonna bump this with a question about this tune. Can someone explain whats up the Timing (KFZW)?

Don't go down this road.

Start from scratch.

I have created my own tune that I'm quite happy with.

Was wondering purely for educational purposes.

Likely scrambled to prevent "copying".

I was thinking that. Looks like the axes might be flipped or something and the conversion's different. I don't know.

Thought maybe it might be something simple.

I also have a Vast Tune ECM that I had done for a customer on an Allroad that I wish I could get figured out. The honest truth is it runs fucking great, but it won't pass emissions because for whatever reason they didn't code it out. And mine was fairly close to their demise when I think it was possible already. So permanently it has secondary air and evap faults, and it won't run readiness even with vag com, and I didn't have them code that out for my customer.

So I'm stuck with an ECM I can't sell, and I paid a shit ton of money for.

AFAIK they were APR licensees and use their flashing/scrambling method.

JHM is APR licensees, which I know because I'm a JH vendor, and I have their flashing setup.

So I dunno, I just dont see them both being APR vendors.

And actually, when I had it tuned from Vast I had to send it in, they didn't have an option to flash online that I remember, so I don't think they were.

You would be incorrect. They were licensing the APR encryption near the end.
