Suzuki with manual transmission - 1.3L engine TBI G10, Specifying ECU (inputs, outputs, mechanically)

suzuki_swift_wiring_diagrams_1997.pdf is helpful, but not enough

Fero confirmed pinout. Factory connector should be used.

Output

FAN relay output? c21/pin20 BLU

Idle valve type ? PWM type, c21/pin24 GRY/RED

Tach out? Tach is triggered from coil directly, not from ECM.

Flying loom DSUB9F RS232

Flying loom EC10:

EC10 pinout:

note: +12V not present


Ecu requirements:


Pins for FETs (by default 30V flyback, mark where low voltage flyback required) should be defined now: (exact mapping enough during manufacturing)

injFETs . Injout Pins:

FLYBACK

IDLE voltage supply:

ignIGBT ignition out pins (6 IGBTs, so ignch4 and ignch5 are logiclevel):

P259 out pins:

v3 POWER:

v3 GND:


Inputs


Ecu connector pin numbering (unconfirmed):
