HONDA DISTRIBUTOR TO COIL PACK CONVERSION USING LINK ECU

This is for those that have a Plug and Play G4X and installing K series coil packs. The coil harness is simple; four 12 volt wires tied to one ignition switched fuse and four ground wires tied to one point on cylinder head or chassis ground. The signal wires are ran individually into the ecu and are located as following:

OBD1 ECU pin

A21 = COIL 1

A18 = COIL 2

A14 = COIL 3

A10 = COIL 4

TACHO Signal goes out from ECU Pin 17 which is AUX 6 into you factory Gauge cluster.

You dont need to wire in the tach if you have a CAN Display or another device to show rpm. I always prefer to wire tach to ecu to use the tacho sweep feature and to fix if you have an aging inaccurate stock tach.

If using T1, Delacruz or other Hall effect sensor:

Trigger 1 = B12

Trigger 2 = B16

Other important items to add if your already making your auxiliary harness:

Oil pressure sensor = VOLT 6

Fuel pressure sensor = VOLT 5

Ethanol sensor = D2

Oil Temperature = TEMP 3

For those that want to go a little further and get engine running here are all setting for coils i use inside software. Many high hp cars i have done have these setting, i highly recommend also doing an ignition test to fire each coil using a spark plug laying on the valve cover or screwdriver to check if each is firing and to make sure they are located correctly. The ecu still uses a reluctor signal to fire coils unlike a Kseries that is a hall effect signal.

Key things to set correctly:

Trigger Setup > Multi-tooth

Trigger 1 = 24tooth

Trigger 2 = Cam Pulse 1x

Ignition main > direct spark and falling edge

Trigger 1 threshold can be from 0.3 - 0.8 for 500rpm depending age of distributor

similar applies for trigger 2 anywhere from 0.3 - 1.2 at 500rpm

Once you have engine running, use your timing light to match your timing.

Go to Calibrate > trigger offset this number might be a little different than my picture because of different distributors. Make sure you first initiate the timing wizard by double clicking the wrench icon.

You still might need to do all main fuel adjustments , sensor checks , table allocation etc to get a good idle. If you still need more help please book a remote session on the main homepage.
