Title: VR to HALL
Post by: beny1989 on November 28, 2016, 01:45:18 pm

Hello
I have a problem with plugging the converter VR to HALL:

How do I connect to my VR signal is converted into the Hall signal as required by the ECU. It is the trigger wheel signal.
Sorry for bad English

Hi

Do your Vems have primary trigges as Hall ? in case, then I think it's better to modify your board to run VR, and connect the sensor directly to the ECU.

Guide to check and perhaps modify is here http://www.vems.hu/wiki/?page=GenBoard%2FManual%2FInputTriggerHardWare

Please post some similar pictures from your own board, and we can verify you hardware setup.

I have an old Megasquirt which only supports Hall.

It can be, that you need a pull-up resistor between +5v and the hall input.

Hi engine now running with this converter but rev up just to 1500 rpm, wiht 1kohm resistor on Vr sensor wire it rev up to 3500 but if I add on more resistor engine dies. Can you help me with those resistors? thanx
