Golf II 1.8 16V GTI (motorcode KR 139 Le)

Assembled ECU features:


Injectors

MembersPage/GolfGtiLpg/SenzoR

injector - pins:

h[0]=01 02 04 08 10 20 40 80


Ignition out

Firind order 1 3 4 2

Is this a 2x2 wasted spark coilpack ?

10A fuse each:

We use channel2,3 instead of channel0,1 (pin33,35) because that is also available in the controller with 2+6 ignition option (so easier to get a spare).

ignchmax=03

h[1]=00 2D 1E 0F 00 00 00 00

h[2]=20 30 20 30 20 30 20 30


Idle air


Sensors

No knock sensor.

1GT101 HALL sensor from WebShop can be supplied from 5V or 12V. See datasheet


Oxygen sensor


LPG injector

6.8 ohm 50w power resistors will be used


Switch between gasoline and LPG

A 2-circuit switch would work

4 relay switches node30 (through 10A fuse) to either

Obviously, get the engine running WELL on gasoline first.


Launch control

Just like for the gasoline switch, pull an mcp3208 analog input to ground.

See EC18pin12,6,16 mcp3208 analog inputs in WebShop ECU specs, all are available in your case.

Measure if they are pulled up to +5V internally
