The review of Autel Maxisys MS906

This review is for the Autel MS906:

I wanted to write this review to hopefully help some others out there. One thing that I really wanted the ability to do is program keys. I could not find any good hard information that this was supposed to program keys. Because of this, I was leaning towards the older DS-708. I decided to give Autel US a call and gather some information.

They told me that the MS-906 was the replacement for the DS-708, but the DS-708 was end of life. They said if you buy a used one, and something happens to the card, then it will essentially be a brick if you don't have a backup. They also told me that the MS-906 would not program keys and that I had to get the pro version that was quite a bit more expensive. This did not make sense to me because if the MS-906 replaced the DS-708, it should do everything that the DS-708 does.

I ended up messaging the seller on Amazon, and he told me that it would not as well. I figured I would order it and I could always return it. Turns out, the MS-906 DOES program keys! I'm very impressed with the scanner. Comparing it to an older Snap-On Solus, it blows it out of the water! The graphing is nice, has a TON of features!

I am very happy with my purchase. Your 1 year worth of updates starts from the time that you register the device. The problem is, you HAVE to register it before you can use it all. Therefore if your plan was like mine and to use it for 2 years or so, then register it to get the free year worth of updates, then that will NOT work.

This is my MS906:


This is the site I'm using:


Galletto v54 vs Galletto 1260 vs MPPS cable

This is: How to read ecu edc15 on the bench in boot mode? can be done with Galletto software or a MPPS cable?

About Boot mode:

Bootmode is a design feature of the processor, as described above.

If you use a tool that can use this feature to write the ecu, then you will be able to write to the ecu in any state, providing it is electronically and physically intact.

Most tools only cover flash, rather than eeprom, but this is often enough.

With quality tools, one will never ever, ever, ever, EVER have to take a soldering iron to the flash on an EDC15P ecu, even with a million failed flashes. (a handful would be unlikely)

Galletto 1260:

Connect pin 24 29f400 to GND.
Power ON ECU.
After 3-5 sec disconnect pin 24 from GND.
Connect Galleto socket.
Start Galleto program.
Select AUDI.
In Driver go to bottom and find AUDI WV ME7.x.x 29f400BB PIN 24 FLASH A MASSA
Press ECU DATA button and check answer.
If you see "Boot mode inactive" you have Galleto USB driver trouble. Often this is conflict Galleto USB driver and drivers from other program for virtual USB COM port. Tray to uninstall all other USB COM drivers.
If you see EEPROM ident all OK.
First read flash few time and binary compare files for check connection stability. If OK - you can write.


Galletto v54:

So this is a quick guide on how to read in bootmode on EDC15P ECU's. I hope some of you can use this too, as there are only guides for this with MPPS.
It appears however, that it's not possible to write the ECU in bootmode using this feature. I have at least not had any luck with it. Feel free to correct me if i'm wrong.

Step 1: Open the ECU
I did this carefully with a screwdriver

Step 2: Locate the 29f400 chip
This is where the flash is stored

Step 3: Fire up FGtech and go to Tools Boot Mode > Siemens-Infineon C167 > Bosch ME7 - 1 Micro - Flash 400 Boot Mode

Step 4: Connect the ECU like this without putting on power yet (On my pictures i have made an EDC15 to OBD adapter, but basically the same):
Step 5: Press Read ECU now follow the instructions (Put ground on pin 24 of the flash > Apply power > Remove ground after approx. 5 seconds)

All gone well Galletto 4 should now read the flash.
I have attached some pictures for more detailed instruction.
Hope this can help somebody!

MPPS cable:

The correct boot mode with ecu fitted into car is like this:
1. Remove ecu cover.
2. remove dash or dash fuse (what`s easiest for you).
3. remove - battery lead
4. turn ignition on
5. put a wire (recommended with a resistor of 1-10K) between pin 24 of 400BT chip and ground
6. put - battery lead back to power
7. wait ~10 seconds
8. remove wire
9. connect galletto and read ecu data in boot mode

if you skip step 2 boot mode will fail to activate. I`ve tried about 3 hours with my car untill i`ve seen that boot mode is inactive while dash is powered on.

Attach: personal experience for share

I have searched for a solution to fix bad flashing/write disaster or error, or bricked EDC15 or whatever you call it, and got to the point where i found many info regarding how to enter bootmode, desoldering and programming with willem programmer, and found many pictures, wiring and so on.

But aparently none of them described how to do this exatcly, i mean how to write with mpps in bootmode. Everyone was saying that is “simple, just write in bootmode”, “MPPS can recover almost any EDC15 ECU”, “I’ve done many times” an so on.

I found this very hard to do, and while searching decided that if i succeed to recover i will do a simple instructions how to do it without asking too many dumb questions.

So here it is in very short description, with pictures.

Note: You do this on your own, and i can't be responsible for mistakes you make!

  1. Remove the ECU. Warm it a little bit up, there is a sealnt which holds the housing halves pretty strong, so after warming will be easier to open it. Dont heat it too much, just to be hand warm. Here is the picture, this is what you will probably see inside the ECU case.


  1. 29F400 Location and bootmode pin 24. For now you have to solder a wire to the pin. To the other end of the wire connect 5k resistor. That’s it for now. Here are the picture of the chip, and the pin to be used.


  1. Prepare all the connections to the ecu and MPPS cableas shown on the picture below.



MPPS Cable Pinout: (it’s mpps v12, but out of date; now is mpps v18)


  1. Pin16 = +12v
  1. Pins 4&5 = Ground
  1. Pin 7 = K Line
  1. When all done and checked twice, connect your MPPS cableto PC, open software and locate the BOOTMODE wirte function. This was tricky for me, but finally i got to this point and after that everything was a peace of cake. Before connectin the +12v power supply to the proper cable as you have seen in the pictures above. And before connecting the negative wire be sure to ground the bootmode pin 24 thru a 5k resistor, and remove it after aprox 15 seconds, but do not disconnect the ecu and MPPS power connections.
  1. Navigate to where you choose brand and choose not VW or Audi etc. but choose GENERIC. I found this Hardly noticable, and found only after a hint in the internet after 16 hours of searching.


After that choose your ECU as stated in the List that opens after you choose GENERIC


  1. Click Checksum Open the file that you want to checksum, the open the file that you have read from your car before making any mods. Above the progress bar you will see something written in GREEN color, and you’re good to go. Then click Write, choose the file to write and wait fo a while for the progress bar to reach 100% and you are done, and as happy as i was that i have saved some $$ on buying programmers, or used ECU’s, or sending to a tuner for a fix.
