Ive looked into the manual of the 1243 and saw yours has 24 and 36 volt modes, the 1225 comes with 2 different hardware models for this

i guess you cant fine adjust your controllers limit?
Which software version do you have

OK now i found it out
i can use an hex editor to alter Factory parameters which i cant see in the OEM software

i discovered the algorithm to find the programmed values
It works like this: save the parameters with the oem software into the .PAR file. Then open it with the hex editor(free to download)
then find the parameter you want to change, its just text
If you read backwards you will find your controllers modelnumber above every parameter name > now start counting 20 steps backwards from the first character of your model number (in my case its 1225-2702)
the value here is the programmed setting in hex code!

use just windows calculator in scientific mode to easily see the decimal value

Example in attachment

This opens new tweaking possibillities!

congrats!

so hows your liberated hardware performing now? what is this controller on btw?

can you post your .PAR? i'd like to take a peek at it!

Default Re: Curtis 1225 overvoltage limit

i tried to load the new file into the controller but the OEM software only READ the whole parameters list, it only loads the parameters with oem access rights

i checked by after loading, to read it again out of the controller and did a file compare and saw the calibration2 value was unchanged
im almost ripping the eeprom chip out and do it with an external programmer

ok ill post my .par file just rename the txt to par

Does anyone know if theres a file uploader software beside the 1314?
or does someone can see the calibration2 parameter with their software?

heres a measure result of my problem:

Ive were lucky the settings are stored in an external eeprom
If not its in the cpu
Actually can you get communication with terminal?
My 1225 gives no answer, perhaps i can send the file in this way

Oh you asked.. I have an Afikim sportster wide seater 3wheel scooter works on 24 volts well 23 in my case..
