Finally an affordable solution to convert the Porsche 911 from CIS to
EFI.

The BITZ Racing CIS to EFI kit includes EVERYTHING that is required
to fully convert to Electronic Fuel Injection from the existing Bosch CIS
system except for the EFI injectors and Fuel Pressure Regulator.

The BITZ Racing CIS to EFI kit uses the MegaSquirt ECU for fuel
management customized for the BITZ Racing EFI kit. This little ECU
has thousands of users and is flexible and user friendly. It has been
used in all sorts of conversions from drag cars to land speed record
vehicles.

Tuning software is Windows/Mac based and is fully customizable. You
can select placement of gauges, have gauges change colors when
thresholds are reached, and set ghost needles to indicate peak values.

The cost of the partial CIS to EFI kit is $1549USD.

The injectors and FPR can be purchased online from
www.summitracing.com or from your local auto parts shop.  The EFI
injectors used are manufactured by ACCEL. They are 30lbs/hr, high
impedance injectors. The part number  is ACC-150630.

The fuel pressure regulator used  is manufactured by MSD. It is an
adjustable fuel pressure regulator and the part number is MSD-2222.  
The fuel pressure regulator mounting bracket is included in the partial
kit.

The fuel pressure regulator requires calibrating to 2.5bar fuel pressure
once installed in the car. A detailed instruction manual is available in
the
documentation section which outlines the calibration procedure and
the installation of a fuel pressure gauge. The part number for the fuel
pressure gauge is in the manual. Click
here for the manual.

Note that the base ECU configuration supplied with the kit assumes you
install the above EFI injectors and the above calibrated fuel pressure
regulator. If you use other high impedance injectors with different flow
rate or different fuel pressure, the base configuration supplied will off.
Low impedance injectors are
NOT supported by the ECU.

The photo below shows everything that is included in the partial kit.
The photo also shows the EFI injectors and FPR which are
NOT
included in the partial kit. You can download a copy of the very detailed
CIS to EFI installation guide by clicking
