The IGN1A Smart Coil by AMP EFI requires no CDI Ignition Module to produce 103 mJ per spark, with a longer spark duration (2.9 ms) than what you'd see with a capacitive discharge. They are the same monster coils used in Street Outlaws No Prep Kings contender, The Hulk!
Each IGN1A Smart Coil features a 19 amp IGBT ignitor built in and can be driven with a 5 volt logic level output - an MS3X or MS3Pro will run them directly (set spark output to going high), and we recommend a 270 to 330 ohm pullup if you're building a MegaSquirt 1 or MegaSquirt 2 to drive them and can fully charge with as low as 2.5 ms of dwell.
Normally, you'd use them for a distributorless ignition as a coil per plug application, however they can be fired sequentially or every crank revolution (wasted spark coil per plug). If used as a single coil with a distributor, you may need to run a bit less dwell to prevent heat buildup from being an issue.
Maximum recommended duty cycle is 40 percent. Requires HEI-type plug wire ends/ boots. Plugs are sold separately. We offer either a 4 foot long flying lead pigtail or a pin and connector kit.
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.
Smart Coil specs:
- Minimum Output Voltage (no load, at recommended dwell): 40,000 volts
- Maximum Output Voltage: up to 81,000 volts (+/- 10 percent)
- 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
Excessive dwell or duty cycle may cause meltdown. As with any race coil, the manufacturer does not provide a warranty.

Warranty Information - DIYAutoTune Un-Assembled Kits
Products purchased in kit form we will guarantee have all parts needed to complete the kit, and the parts will be in new and working condition when we ship them to you. If you find a discrepancy please notify us. We're pretty easy to work with and we'll do our best to take care of you quickly. Obviously we cannot warranty your assembly work of a kit. If you get stuck we suggest posting a thread at www.msefi.com or www.msextra.com and emailing us the link so we can attempt to chime in and working together with others we can usually help you get to the root of your problem. That being said most people don't have any problems assembling our kits, they are clearly labeled and go together just about as easy as any kit could.
Warranty Information - DIYAutoTune Assembled MegaSquirt ECUs and Accessories
This section applies to any product that is available as a kit, but that we also offer as an assembled product. Examples would be standard MegaSquirt I and II ECUs, Stimulators, and the like. Standard off-the-shelf MegaSquirt ECU Assembled units are covered by a one year limited warranty against manufacturers defects. Contact us if you believe you have an issue that should be covered under warranty. We will discuss the issue with you and provide an RMA number and an address to ship your unit to. Our tech will evaluate the unit and if a problem due to manufacturer defect is found we will repair it free of charge. We will cover the cost of shipping from our shop to you up to $25; we will need for you to cover any cost of shipping beyond $25 and the cost of shipping the unit from your location to our shop. If we determine that the problem was due to mis-use, mis-installation or improper modification, our shop rate will be $75/hr plus materials to repair your unit (one hour minimum).
We do not mind the modification of the unit as that's the spirit of the MegaSquirt project, just understand that if your mod appears to be the likely culprit of damage to the unit that we cannot support the unit under warranty. Note that extensive modification may complicate the troubleshooting process, and in some cases it may be neccesary to reverse modifications in order to return the unit to working order. Charges will apply for the time required, and in these case we cannot be responsible for putting custom modifications back in place after having to remove them to resolve a problem.
