DESCRIPTION

The high ohmic fuel injectors have been utilized since the production of 1988 RX-7 turbo, non-turbo and convertible models. Because of this change, the
EGI control units have been modified and the solenoid resistor has been discontinued. Therefore, the EGI control units should not be interchanged or
swapped.

CAUTION:
When troubleshooting driveability or fuel injection problems occur, do not interchange different part number EGI control units because this may damage
the control unit or injector.

PARTS INFORMATION

Please refer to the following table for correct part number usage:
