ISA3 features::

  • a specially designed  map of correction, which is independent of rpm corrections vs. injection pulsing,
  • precise acquisition of the reference map for petrol pulsing, taking into account engine temperature,
  • identification of the closed and open loop mode in real time.

Compatible with the older STAG-300 ISA 6 and 8 controllers with respect to the harness compatibility. It can be used as a replacement. Replacement of the older controller with STAG-300 QMAX BASIC is performed in the Plug&Play mode - just disconnect the old controller (e.g. the damaged one) and connect the new one. You get a new generation system without any modification to the harness.

Safety for many years
The longest guarantee in the STAG range, which confirms the excellence of the controller.
