Vems board older than 3.7 does not have additional holes to mount LowZ extension.
For those who added this board on 3.3-3.6 boards with no holes, how did you mounted it?
Drilled and expanded middle hole, or mounted it outside of Vems case?
I have low z board in v3.3 version inside the box. Same position like on v3.7
I got version 1.1 board from VEMS. its different from 1.0.
I have it mounted upside down, becouse i had to solder that side of pcb to get good connection, i guess is does not matter if A pad is on B channel fet they are all the same circuts...
Flyback wire from harness to goes to +12v pad like on picture, that +12pad is connected to anode of 30v diode on extension.
I left PWM off 100% and it works as before.
Need to test it with LPG low-Z injectors and PWM
