After I read this I went their web site, looked at the FAQ's and downloaded the manual to read. They list a number of controllers and said to call them about others. I called them today, twice, about it and the power requirements. Their Rep said that it will work with other controllers. From talking to him about it and from other reports though it's my understanding that a pendulum or motion sensitive type does it better.
My interest is that for the purchase of a Ford Ranger I specified the Redarc remote head controller due to dash space issues. After I became more aware of the different controllers I deleted that but when car went to accessory fiters it got done anyway. Ford Dealer agreed that it wasn't my fault so I got the controller for free. So it's no loss to me to now want to change it to P3, except for holes in dash.
My second call to ALKO though was about power supply as diagram shows 30A supply from main car battery. I thought that it would come from van battery but that's not what ALKO want. I want to fit dual battery system to Ranger and take feed from there as the ESC could drain main battery if I forget to disconnect at long or over night stops etc. Rangers already have enough battery issues as it is.
