NOT to stop the engine * '''EC36/25 = 12V (ignition on) => OFF (ignition off) is the proper way to stop the engine.''' ---- '''Outputs (v3/20216 6 IGBT + 2 logiclevel; low voltage flyback on EC36/6) ''' (replacement of v3/375 8 IGBT). Will need another replacement, after v3/20216 damaged after igncoil test. Will need 2nd RS232 and BT-RS232. ---- '''important: Ignition''' * old: M & W from IGBT outputs * '''new: TFSI: logiclevel output for active coils''' ** '''Use: 4 stepper outputs + 1 logiclevel ignout''' ** eg.
