Description

The G4+ Atom II runs the same microprocessor and firmware as the G4+ Xtreme.

Designed and built to be the best “value for money” entry level ECU on the market.

While the G4+ Atom II is entry level, the following is not compromised:
The loom (sold separately) is AVSS automotive quality cable
The same mounting technology as our higher level ECUs
A fully extruded mounting plate is included
Mounting hardware is completely hidden for a fully professional installation
Waterproof automotive plugs
The same tuning features as our high-end ECUs – tuning is not compromised in this “entry level” ECU
Full configurability, no preset input/outputs
Logging
Closed loop fuel if external devices added, e.g. WideBand Controller
Industry standard waterproof connectors, mounting bracket and loom, all supplied with your G4+ Atom II
Spec 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 connector
– 5V out

* unused ignition drives can also be used as auxiliary outputs.
