Ignition and engine upgrade is one of those vehicle modifications that must be well thought of before giving it a go. This is because choosing an incompatible component or making a mistake in the installation can bring serious damage to the engine and to the vehicle itself. We want to help you in deciding what brand and type of ignition module to get for your ride by testing out one of the known brands out there--the AEM Twin-Fire ignition module. Since our ride has a stand-alone engine management system, we picked the 8-channel configuration, and here's what we have to say:
- Can be used on 3-, 4-, 5-, 6-, 8 -and 10-cylinder engines featuring four or more ignition coils
- Provides spark energy even for engine speeds above 10,000 RPM
- Lightest and smallest ignition module available in the market today
- Compatible with coil-on-plug as well as distributed ignition systems
- Can be used for race cars utilizing aftermarket stand-alone engine management systems
- Ensures 540v primary and 54,000v secondary voltage energy
- In California, it is legal only for racing vehicles, which may never be used on a highway
- Produces up to 189mJ spark energy per capacitor
- Tachometer output included
- Accepts trigger inputs coming from electronic DIS type ignition systems as well as from igniters
- We were impressed by how fast the AEM ignition module provided our high-RPM engine with the quality and quantity of spark it needs to work at its best.
- With its 5.5" x 4.625" x 1.375" dimension and weight of 1.5lbs, we were convinced that this is, by far, the tiniest and lightest CDI on the market, so racers need not worry much about the extra weight it could add onto their ride.
- We give thumbs up for the AEM Twin Fire Ignition module's 12 volt, square wave tachometer signal, which isn't just helpful in driving aftermarket tachometers but also in shifting lights or data-loggers. It gives a pulse for every ignition trigger signal.
- Improper adjustment and installation of this ignition upgrade can seriously damage the engine or the vehicle, so we believe that it must be installed only by those who have enough DIY experience and sufficient mechanical know-how. Though we're already experienced DIYers, we were still very cautious during the installation process. We highly recommend that you get a wiring diagram for your specific ride before the installation of such module.
- It would have been great if it's also compliant with California's laws and regulations.
When it comes to quality and performance, this product didn't disappoint, making it worthy of an overall rating of 4. We are in awe by the huge improvement it brings to our ride's start-up performance. But though we got the installation right, we can't say that it was such a hassle-free experience as we have to take extra care in dealing with every detail of the installation process. After pulling everything off, we believe that this task isn't for people with little to average DIY experience.
