How to feed the ecu

[sportknight]

hi guys,there are several threads that explain how it works a bdm etc..

however I had a a doubt

best thing to do to feed the ecu?

should have a charger that is 12v you can use both to power the unit to keep charging the battery when mappo,or maybe it would be worthwhile to take a booster and do all of the cos? even if it goes away in the current, you can always go ahead without blocking,or even something adjustable so? you can map the bmw that apparently need a nice voltage(14 volts)?

you what have you done?

put the booster and go quiet!!!

[sportknight]

the problem for the booster ? sometimes wanting to do things quiet at home with the booster, my mother would make me fly from the window to me and him

I don't understand if you talk about the reading in the bdm or the obd

[sportknight]

reading in the bdm,I wanted to know what you use to power the ecu,maybe even that you have done,if you are constructed of wire with the niples from the plug on the ecu or what

a 12v battery,6 ah with a small charger you make a nice impiantino with fuse protection, and six horses.

sorry but on some movies I saw that the unit was not powered,was connected only to the bdm through the block,why?

and the better that food is always the ecu from the comb and nn from the board . I use a power supply 13.5v 4A , always use the one x programming tour or bdm.
