MGM Low Voltage Cut Off - Owners READ

[lutach]

I will have to think twice about send the 2 MGMs I have. I have the 8012, but that one is working good.

Well I ran my truck yesterday with the updated 22418 and my Neu 1521. There is a huge difference in power now! I knew that I was not getting all the power that this setup was capable of. Before the truck was impressive, now it is just plain ridiculous.

I don't think that everyone will notice as much of a gain. MGM had said that the issue was with large motors that pull a lot of current. I'm just guessing that a 1515 might be a bit more punchy, but anything over that will be quite a bit improved.

My run was cut short (I knew in my head that something was going to break!) when the threads that hold my shock tower to the FLM bulkless failed and the shock tower came loose after a poorly landed jump. I think the screws that come with the FLM are too short because they only seem to engage about 1/3 to 1/2 of the thread. I am sending my bulkless to FLM today and ordering some longer M4 screws. I can't wait to get this thing back out.

Another benefit of the new software on the MGM is that my motor ran super cool. Now that it is getting enough juice I am sure it is more effecient. I was hoping it would run cooler but I didn't know it would be that different. I ran the MGM software when I got back and sure enough the numbers were much improved from before. I don't have the saved screen infront of me with the exact numbers, but I can say that for the first time the data had a number for the "current at full throttle". Peak amps were up near 400 and max RPM was 37500ish. Before the upgrade the max RPM I would have after a run was in the 32000 - 33000 range.

All in all I would say that the upgrade was worth it. My controller was dead at the time anyway. There is the risk of loosing your controller in the mail if you do the $10 declared value thing. I think I would only send the controller in if I knew that I was missing power that I should have or I was running the controller in "cutoff" mode and the truck was constantly cutting off even with high quality lipos (due to the current cuttoff, not the low voltage lipo protection). Remember that my controller ran without cutting off in "reduce RPM" mode, it just performed poorly. In cutoff mode the truck was useless. I can't comment on the brakes, I use mechanical.

Realy good!! But in which mode do you run your controlller now?? Cut off or reduce RPM??

I'm running Reduce RPM. My truck is down for the moment but I am going to give cutoff a run on my next outing. I am quite sure that it isn't going to cutoff. Just looking at the data on the software I can see that the controller is allowing full throttle output, which it never had before. It will be a week or two before I get a replacement hybrid bulk from FLM though...

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

Are you checking the version number with the flash software or the normal CC_02 cable and USB_COM? I checked with the CC_02 combo and it said ver. 3.22 . I did notice on the flashing software that the version number wasn't 3.22.
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)

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.

That does not help ...

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

Wallot, did you repower the controller after the update and before switching it to the cc02 and controller software? Thanks

[wallot]

yes i did repower the ESC
