NefMoto

Hello NefMoto community, this is my first time posting cause normally I find everything I need or don't have anything fresh to add.
On to the point,

I bought Eurodyne Maestro 7 and I flashed my first tune after having my car up on jacks for almost eight months. Turns out it was the wrong tune... It was labeled AWM however I guess my ECU called for the base tune under AMB... whatever...

Now the ECU is unresponsive, can't connect to Eurodyne Flash, Nefmoto Flasher (Not in boot mode or normal), and Galletto keeps giving the "Boot mode is inactive" error.

I think it's important I note I'm using the Eurodyne Tapp cable on 2014 FTDI drivers. Nefmoto recognizes the cable so I'm assumming it works.
I have the ECU on the bench right now and have tried grounding Pin 24 for bootmode.

Want to try the alternate method for boot mode but the pictures I've seen where people solder switches aren't of the ECU I have so I'm not going to go around touching contact points I GUESS might be it.

Tried 2009 FTDI drivers.
Uninstalled any and all software that uses the OBDII cables (VCDS lite and VCDS, all eurodyne software, nefmoto) and installed only whichever one I was trying at that moment. Nothing.

Any help is deeply appreciated, I really can't afford to spend any more money (Had to spend $70 on a DC Power supply... will probably return it and make an ATX one though lol).
If any pictures or info is needed I will gladly oblige and am willing to try any solutions again to verify.
Thanks in advance!

ECU: 4B0 906 018 DA

                                                                            [SOLVED]

Bought Galletto 1260 cable from eBay.
Got a hold of a laptop that never had any cable drivers/software installed. It was Windows 7 Enterprise, 64-bit.
Made sure to prevent windows from automatically installing any drivers. Followed the FTDI pdf on how to install the drivers to the letter.
Only installed the VCP drivers.
Installed the Proper English version of Galletto.
On first try Galletto gave me a write error at 60%, but I was beyond excited that it even began writing.
After a couple failed attempts (boot mode inactive) I deleted the driver software and reinstalled.
Worked like a charm the next time!
Hope this helps the next guy, all I needed to do was try a fresh laptop. Wow.
Thanks everyone!

Are you familiar with the bootmode process? Meaning, how many times have you gone through it? Have you verified the cables and software you're using are able to successfully put an ecu into bootmode yet?

I've never gone through the bootmode process before attempting on this ecu and this is my first time bench flashing anything.
Here's what I've done:

In car:
1.) battery disconnected, waited a few hours
2.) key in; ignition on
3.) Grounded pin 24 via foil surrounding ecu
4.) had friend connect battery (car was being powered by jumper cables connected to a truck)
5.) same results.

Variations: amount of time pin 24 was grounded
~1 sec
~5 sec
~10 sec
~15 sec

On bench:

Basically what was described above except on bench.
Variations:
Saw a post here where someone said clicking read on galletto while still grounding pin works. Didn't work.
Read post saying to disconnect ignition and immobilizer after typical "ground pin 24, turn on power supply" procedure, then try using galletto or Nefmoto flasher. Also didn't work.

:\

Nefmoto software tries 3 times to connect through boot mode before stopping. Also, I tried to connect the Nefmoto Flasher in bootmode at all speeds. Exited out of Nefmoto Flasher every time I changed speed too

Can you snap a pic of which pin 24 you are grounding?
Can you provide the pinout of the bench cable you are using?

Definitely clicking read while pin is grounded will NOT work.

Also, Nefmoto "bootmode" will not flash, but it can tell you if you are in boot mode or not.

Second pin from the right

Have also followed the trace on the board and tried the little lump of solder (no idea what the technical term for that is)

My "bench cable" is ghetto-rigged.
Cut slots in the insulation of the wires so I could slide the wire directly onto the pins, the two reddish ones are at +13.8V (based on power supply rating) Pins 21 and 62.
The yellow cable is my K line, it goes straight to my Eurodyne Cable K line pin. It's connected to Pin 43 at ECU.

At the furthest left the two bottom pins are grounded, and the middle pin is also at +13.8V

I quintuple checked none of the connections were shorting to any other pins.

And here is the Eurodyne Cable and its pins

I followed all the connections posted on the sticky for bench flashing,

And I forgot to ask, how do I use Nefmoto to check if it's in bootmode or not? I switch from KW2000 to bootmode, select my cable and then press "Connect Boot Mode" and look for what??

This is what the status window outputs:

So I'm assuming it never even gets a response from the ECU...

I have a professional multimeter and know how to use it by the way!

Update: Just checked the voltage straight out of the Power supply when it's plugged up to the ECU. Reading +5V... Tested the powersupply by itself and it's outputting the correct 13.8V.
Sounds like bad news... Maybe it's a bad ground?

Okay, stupid question and will be pretty embarrasing if it ends up being the case........

Should I connect the ground terminals out of the ECU and Eurodyne cable to the neg terminal of the power supply?
I was under the impression the negative terminal would be -13.8V (Memory from my labs at school) but I forgot that in my lab our power supplies had two outputs, so two pos. and two neg., and we would have to jump them in order to get a neg. Voltage.

Here I only have a single pos. and single neg. terminal coming out sooooo...........

At the moment I grounded the entire circuit to a nice piece of metal I hit with a rotary wire brush......... lol

Yes, you need common ground on the neg terminal of your PS.

There are no negative voltages here.

Okay, so still nothing. Set up the power supply correctly this time (That was embarassing) but still nothing. Nefmoto Flasher gives same message and Galletto is still saying Bootmode inactive :\

What else could I check?

Are you using a Galletto cable?  Is this a 1.8t ECU?  Mine didn't work with grounding pin 24 and needed a 10k resistor between that pin and 10 along from it.

There's a picture on another thread.  Are you powering pin 44? too for the immo?

Thanks for the response!
I'm not using a Galletto cable, but what I did was hex edit the serial number from my Eurodyne cable into Galletto so it would still work... However at this point I'm suspecting the cable itself is what isn't letting me flash.
It is a 1.8T ECU and I haven't tried using a resistor. I'll go out and get a 10k resistor right after I get off work (4PM EST) and give it a shot after reading through your post.
Oh, and yes I'm also powering the pin for the immobilizer,
I'll get back with updates!

read the proc datasheet!

http://nefariousmotorsports.com/forum/index.php?topic=1586.60

Bottom of the page, 10 resistor.  I don't believe in that method.

Where are you?  I'd be looking at buying a Galletto cable to get this working.  Drivers good?

I found my FTDI cable wouldnt flash with galletto even when i edited the serial number in the software. Luckily i had the galletto cable and once i installed the galletto drivers (not the normal ftdi vcp drivers) it then flashed 1st time.

So maybe you could try using the ftdi driver but install the galletto drivers and uninstall the FTDI drivers.

Also have you given pin 121 on the smaller connector 12v

not needed in bootmode

Yet another thread going into 2nd page, and all the info to solve the issue is in one of the very first posts.
You need to first ground pin 24, THEN power up ecu/turn ignition on. You are doing it in the wrong order.
When the processor boots (and it does that when getting power) it needs to see flash pin 24 grounded at that very instant.
If you are turning it on first, and then grounding the pin you are accomplishing nothing.

He said he connected the battery after grounding the pin.

Fair enough.

Could be a driver/cable issue then.

Does anyone else have this 10k resistor issue? Because there is only one thread on it here, and it seems to go against the grain compared to normal bootmoding.

Mine DOES NOT accept grounding pin 24 no matter how long I do it for.  Bridging out the two pins on the thread I linked the whole time with a 10k resistor works first time, every time.  No too sure if the ME7.5 ECUs/1.8t specific? have a different proc?

Next time I've got one apart I'll get the proc number and get a data sheet, but it's weird.  No-one speaks of this issue.  Is it because everyone's 2.7 freaks?

Never needed a resistor on anything I've booted. I use the power supply feed ground.

Did you check the proc data sheet?   Pissing in the wind otherwise

I use a 120r iirc mostly about as a suitable probe lol.

You just need to pull the pin low (recommend 10k iirc) but I didn't have any luck.   Imo you really should use a resistor.

looks like it, what's he voltage on the can wires? try a 120r croc clipped across them too ecu might not be an endpoint (seen this before), shouldn't affect boot mode but will let the ecu boot so VCDS can read it etc

Cable/driver as said

I don't like how you were bridging pins in  the car the datasheet (read it) explains boot mode.

 galetto, boot more is not galetto you can boot he ecu itno boot mode then 1 min later then open galleto, it will work.

I used to have all sort of boot mode issues until I got a junk/scrap ecu socket soldered it up, used a 12v power supply from software and croc clips, I ground from the foil with yes a croc clip to the negative part of the power cabling.

I then got a obd2 extender to make life easier taped it all up and never had an issue.

I bricked my ECU the other day, i hadn't needed bootmode until this point and i too struggled but eventually got it using this Picture.

10k resistor as pictured left connected throughout the process.

Did not work plugged into Car loom

but it worked on bench with the ECU pins as pictured then +, GND and Kline on OBD cable.

I used MPPS V16 for boot mode flash and argdub tool + ebay blue KKL cable for 95040 in bootmode ( i couldn't get Galletto to work with mycable)

tested on two ecu's

1ML906032A
8N0906018BH

You'll have to trace the pins and see the difference, iirc there is a thread somewhere where you have to remove an smd resistor on an ecu type

Left connected DURING flashing is generally a bad idea. That is likely luck more than anything else. If in doubt, READ THE DATASHEET FOR THE ECU.

I can't stress this enough.

It's not luck applied to this though; I can confirm it too.  Attempted to just brush during booting, grounded the pin individually and then soldered it on.  Works when connected during the whole flashing process.

However, you're right that the datasheet for the ECU needs to be read first.

The 10K is not attached to the bootpin in this instance.

Understood. Thanks for the clarification!

Presumably he is referencing this photo:

^ i leave that one connected when doing the st10's. never cooked one because of the fact.
