Yes you can.

For those that have firmware 3.20> you will need to download 2 small programs from the MGM website CLICK HERE. You will also need a CC_03 cable and a USB_COM ver. 3.__> .For some reason I couldn't download the english version of the flashing instructions. If you can read Czech you can download THIS one. :lol: I managed to work it out any way and have upgraded my speed control from ver. 3.21 - 3.22 .
I am still yet to try it out but will post back when I get a chance.

Cheers Andrew

Hi Andrew, I managed to download the programs from that website and I went thru the software update process.. Software says that Update successful but when i restart the controller it still shows up as 3.21. Any tricks I need to do after the 'Update successful' message to get the new firmware active? Thanks

Regards Andrew

Checking with the Controller software and CC-02 cable and the version is still 3.21! After the 'update successful' message, I just shut-down the software and restarted the controller. hmmmm..

I just ran through the whole process again and mine still says ver. 3.22 . It may just be me but I think every time you swap from the flasher program to the controller program I had to remove the USB cable from my computer and then reinsert it, otherwise the controller wouldn't show up?????
A couple of things to check

1. What ver. is your USB_COM?
2. In the flasher program make sure the drop down box is says "Update device through USBCom" .

What ver. of windows are you using? I'm still running XP. (don't know if it's a problem but thought we might be able to eliminate a few possibility's)

I have some news to you and all mgm users that have this issue, it accelerates when you try to brake, mine only did this in4 or more poles like neu or align 600xl...

This is my story:
- Problem 1: First I had a 12018 (3.14) that does glitch all the time (instant braking while accelerating or brake all the time).
- Solution 1: MGM changed it for a 9032 (3.21) (paying the difference :) )

second part:
- Problem 2: the new 9032 accelerates while I'm trying to brake, but as you know only with 4 or more pole motors, with feigaos the esc worked perfect.
- Solution 2: sended the 9032 with a align 600xl motor to MGM to show them the issues.

Today I have receibed my REPAIRED MGM 9032 (3.22), MGM told me by e-mail:
"Problem was in defective processor. Rare case"

so... its not the problem of radio, receiver, battery, connectors, motor, etc... it was a defective component of the esc, so...

lutach, you have to send it to them, tell them my case, because it seems to be the same problem. This esc seems to work ok, it brakes PERFECT with the align 600xl motor, feigao, and neu motors :) this is 3.22 firmware.

If you have any question let me know and I'll asq you.

This weekend I'll test it to see if it's perfect or don't work perfect.

I just tested mine and I too was getting a surge when I went from throttle to brake. I then did the "AUTOTUNE" procedure and the problem went away. I then used my USB_Com and hit the default button to see if the problem came back, it didn't. I then tried a few different settings etc. to try and reproduce the "surge when braking" and couldn't reproduce it.... :neutral:
Not saying doing the "AUTOTUNE" will fix everyones problems but it maybe something for people to try before they send off their controls.

Cheers Andrew

My issue was a deffective processor, not the firmware, I suppose they upgraded my esc to have the latest software, but tue "accelerate while braking" seems to be a hardware problem.

All people that has this problems contact with mgm, and do all the tests that they tell you, they finally find a solution, (with me was about 3 escs and 3 months off nightmares) BUT FINALLY...
all the tests I have done with 2, 4, 6 and also 12 pole motors are OK, the accelerating while braking issue has dessapeared. the esc arm ok all the times (before I had to power on, off, and on to make it work :( )

and.... Countryhick... don't send the esc to mgm if you can do some tests, it's fustrating to not have the esc at home and don't know when will be at home and if it will work ok or not.

Today I'll test my mgm 9032 in my crt with 10s a123 :)
I'll let you know.

and.. sorry about my bad english :oops:

I didn´t manage to update my ESC with the MGM Flasher 1.0. What did you do after the update successfull window ?

English UPDATE pdf

Attached is the English pdf for updating the firmware on MGM controllers ver. 3.2_> .

Yuppp, followed that exactly and still the controller software reports it as 3.21. Wonder why....

Try disconnecting the USB cable from your computer then reinsert and check again.

Yup, same here. After restarting the controller and replugging the USB back in , the old version of the software is still reflected. hmmmm

No issue with updating to 3.22. on my 4412-3, now 16018-3 to go
Did the update, unplugged USBcom pro PC! as mentioned in the manual, changed CC03 for CC02, replugged USBcom, launched controller and 3.22 was there
