Performance Electronics, Ltd (PE)
installed a standard PE3 Series ECU
in a customer vehicle. The PE3 ECU
completely replaced the original FAST
EZ-EFI fuel injection and MSD ignition
systems that were in the car when it
arrived at PE. The engine was a rebuilt
Ford 289 CID with cast iron heads, low
compression, aftermarket intake and
exhaust. No other modifications were
made to the engine between tests.

The vehicle started and ran when it
arrived at PE with the FAST system. It
had been driven by the customer prior
to arriving at PE. Driving on the street
revealed that it did not pull well and
seemed to be drastically down on
power above 3500 RPM.
In order to ensure the FAST system
had fully ‘self-tuned’, PE engineers
drove the vehicle for 8-10 hours both
on the street and on the chassis dyno
before performing the baseline tests
shown to the left.
The before and after tests show the
drastic improvements made by
switching to the PE3 ECU and tuning
the system.
