If it isnt a problem or a suggestion it probably goes here.

IGN-1A coils

Post by skylinegtrhr »

Hi any one have experience with them?

Here is the connector pinout:

A - Ignition signal from ECU

B - Logic ground, connect to ECU ground

C - Spark wire ground, connect to cylinder head

D - Power ground, connect to battery negative

E - 12 volt power

The coil dwell starts when a 5 volt signal is applied to pin A, and the coil fires when the voltage drops to zero. The signal is similar to an LSx coil, although it does need a bit more current to trigger than the LSx coils.

Coil specs:

Minimum voltage output (no load, at recommended dwell): 40,000 volts

Output energy: 103 mJ

Spark duration: 2.9 ms

Primary resistance: 0.5 ohms (not directly measurable)

Primary inductance: 4.8 mH (not directly measurable)

Secondary resistance: 8,500 ohms

Secondary inductance: 22.5 H

Turns ratio: 71.1

Maximum current: 19 amps

Maximum battery voltage: 17 volts

Nominal dwell: 3.0 ms


I guess that on s14 sr20 we should be able to adjusts dwell time and dwell duty cycle for this coils?

yes dwell tables are adjustable.
