Aftermarket hardware

This page lists the various aftermarket hardware.

Aftermarket ECU's
In direct injection engines (1), open-source and closed-source (commercial) aftermarket ECU's allow setting the amount of fuel injected as well as alter the timing, and this for both liquids and gases.

It thus allows for water, alcohol, biogas (or methane), and even nitrous oxide injection to the engine. All these will help to increase speed and eliminate emissions (except for water, which just reduces knocking, and allows more fuel to be injected)

This hence allows people to make their car with conventional gasoline engine (with direct injection) both faster and more ecologic (emitting nothing, if only the alcohol, methane or nitrous oxide is injected, and no fossil fuels -so no dual injection-)

Commercial ECU's's (intented for gasoline engines) include:
 * MegaSquirt
 * VEMS

Open-source ECU's (intented for gasoline engines) include:
 * Speeduino
 * rusEfi
 * FreeEMS
 * SECU-3

The aftermarket ECU's intented for Diesel engines can also allow for extra comfort when using pure plant oil. This, because the the fuel tank or fuel line requires heating. There are both electric heaters and water-based heat exchangers (running from the water coolant tank) for this. The electric heaters work immediately, the water-based heat exchangers don't work from the start (so require either an additional electric heater or a 2-tank system so they can be started on conventional diesel). It would be useful to integrate the ability to connect/disconnect electric heaters and/or open/close valves (the latter for if a 2-tank system is used). So far, most ECU's do not allow this, but it could be integrated in later versions allowing easier use with the heating system provided by PPO kits (see further down below).

Open-source ECU's (intented for Diesel engines) include:
 * DMN-EDC

Pure plant oil kits
Pure plant oil kits allow for running your Diesel engine on pure plant oil (PPO). They basically contain the heaters (or just heating pipes) along with filters and sometimes an extra fuel pump. They come in 2 forms: single and double tank kits. Single tank kits start directly from PPO, whereas 2-tank kits start from a lighter fuel (like petrodiesel or ethanol), and then switch to PPO from the other tank, once the engine is hot. Some kit manufacturers are:
 * Plantdrive
 * Greasecar
 * Diesel-therm
 * Bioplantrix
 * Goat Industries
 * Frybrid
 * Biocar

Display systems
These include the:
 * MPGuino
 * OBDuino
