Xtreme ECU’s advanced configuration enables today’s complex engines to be optimised. Flexible options over the control of inputs and outputs allow the user to design their own functions to control all sorts of devices.


Precise control of injectors and ignition angle are guaranteed at very low or high RPM or manifold pressures. A very high level of protection from interference and tolerance of trigger input errors has been built into this ECU, ensuring a smooth running engine even under the most demanding conditions.


8 x fuel & ignition.  Requires “A” & “B” Looms.
