Summary of change:
'''Suzuki ''' - 1.3L unknown engine Specifying ECU (inputs, outputs, mechanically) suzuki_swift_wiring_diagrams_1997.pdf is helpful, but not enough, by far. '''Factory connector should be used.''' * can be placed in VEMS box (best) ** or factory box (seems more difficult to get right) ** or even adapter small harness (not really justified) '''Output''' * '''Logiclevel ignout .. pin10 ''' (no idea if 5v/12v needed). External ignitor triggered from c21/pin10 ORG A/C ? AC-idle up in c23/pin19 BLU/RED; AC Cut-out c23/pin17 LT GRN/RED FAN? c21/pin20 BLU Idle valve type ? PWM type, c21/pin24 GRY/RED Tach out? Tach is triggered from coil directly, not from ECM. Other ? '''flying loom EC10 or SSC would be nice''': * a few extra outputs * a few analog inputs (min 2 pulledup, min 1 with no pullup) ---- '''Pins for FETs (by default 30V flyback, mark where low voltage flyback required) should be defined now''': (exact mapping enough during manufacturing) injFETs .
