D-Jet ECU Options

[Bobco]

Hi World


Will a D Jet ECU for a 2 Liter work for a 1.7 Liter Also dJet?

Thanks

Not a very good idea to mix and match D-Jet parts.

I would call the D-Jet system a comparative system. There is no real feedback to the ECU from any sensors.

All the ECU does is take in signals from the sensors and compare those to on board pre-programmed data, all in analog form.

Example the head temp sensor, it's resistance is compared to an on board resistance and the increase or decrease changes the pulse length of the injectors.

Mixing the components will cause tuning problems and fuel consumption issues.

The Bosch engineers used real data to set up the D-Jet ECU, but not until the introduction of stuff like the O2 sensor did the engine start telling the ECU what might be happening.

Once you have assembled the correct collection of parts for a particular "year" than you will be able to tune the system making predictable adjustments.

All of the parts necessary for a complete system are available, there were thousands of D-Jets made and some more desirable items may cost more and others cheap and abundant.
