The G4+ Atom runs the same microprocessor and firmware as our top ECU, the G4+ Xtreme Designed and built to be the best "value for money" entry level ECU on the market. While the G4+ Atom is entry level, the following is not compromised: The loom is AVSS automotive quality cable the same as is used in 21st century car manufacturing The same mounting technology as our higher level ECUsA fully extruded mounting plate is included Mounting hardware is completely hidden for a fully professional installation Waterproof automotive plugsThe same tuning features as our high-end ECUs - tuning is not compromised in this "entry level" ECU Full configurability, no preset input/outputsLogging, even closed loop fuel and knock if external devices are added (WideBand Controller & G4 KnockBlock)Industry standard waterproof connectors, mounting bracket and loom, all supplied with your G4 AtomSpec overview:Four injection drives, Four ignition outputs, Three analog inputs (you choose, oil pressure etc.)Two temperature inputs (usually water and inlet air temperature)Two digital inputs (e.g. vehicle speed and logging switch - you choose)Four auxiliary outputs (e.g. fuel pump, fans, boost control, O2 heater etc.) *One, thirty four pin, waterproof connector5V out

The easy way to detect engine knock - The G4+ KnockBlock is an essential tool for tuning and can aid in the early detection of incorrect timing, lean air/fuel mixtures and mechanical issues. Dual Channel knock monitoring using headphones and/or analysis software

Free yourself from the constraints of the factory ECU. The Link G4+ Plug-In fits discretely inside the original enclosure. Installation is a breeze with no alteration of the factory wiring loom required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches (the number available depends on the application) Pricing Varies by application: SPECIAL ORDER ONLY!
