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?

Re: IGN-1A coils
yes dwell tables are adjustable.
