Megasquirt MS3 PNP Fiat Coupe 2.0 16V Turbo


Megasquirt Plug And Play for Fiat:

  • Fiat Coupe 2.0 16V
  • Fiat Coupe 2.0 16V Turbo
  • Fiat Tipo 2.0 16V
  • Fiat tipo 1.8 16V
  • Fiat Tempra 2.0
  • Fiat Croma 2.0 16V y 2.0 turbo (Unable to check on this model for now)


  • It maintains all source sensors, including trigger wheel and cam phase sensor installed in the distributor or in the head, except for the MAP sensor that is internal.
  • Sequential injection, only supports high impedance injectors.
  • Ignition by distributor ignition or Wasted Spark, with option in both motors to switch to sequential ignition or logical independent coils (type TFSI).
  • Anti-lag
  • Turbo pressure control by gears. You need to add a speed sensor.
  • Although it is not mandatory, it is recommended to change the idle valve for a more modern one with greater resistance in its winding and greater air flow, especially if you want to use anti-lag.

The selection of the ignition option must be correct for what the engine has installed. The ECU of an engine with distributor will not work on a motor with a wasted spark, not being interchangeable, and the ignition module must be the original one, it cannot be eliminated or replaced by another model. The circuit for independent coils is different from that designed for the original ignition, if selected, the ECU cannot be used with the original ignition.

The units are shipped with a boot configuration, but we are still not sure that it is 100% correct, you may have to modify some parameters. If you need help, do not hesitate to contact us.

You can consult the installation manual of the Megasquirt MS3 PNP models at the following link:


It also maintains most features of the MS3 model:

  • Many more features

Some features may not work together. Some features may require additional circuits.

No unit is shipped with a map of the finished engine, all of them need an adjustment to the engine in which they are installed, especially when there are modifications. In fact, this is what is sought when installing one of our units, adjusting the engine to its modifications or managing systems that would not be possible with the origen unit. Of course this costs more time, but the results are usually better.



The Megasquirt engine management started as the units with an educational character, they maintain it, over time they have become management units that have the same characteristics as other brands, in some cases higher, much cheaper price and without any restriction Just look at the characteristics offered by each model and the number of fuel and ignition adjustment maps offered.

MegaSquirt® power units are not approved for emission regulations. They are designed for competition vehicles that do not run on public roads, old vehicles that do not comply with emission standards and training centers where teachers can teach students the operation of an engine management unit since inside and without anything hidden.
