Thread: Brains trust - what's the diff between normal and EDC injectors?

EDC ones have little wires hanging out of them for the EDC to control them, so I'm guessing they are semi-solenoid controlled.

There is a pic in the Bosch injection book on the site here somewhere.
I was only looking at it the other night.

Yeah I just checked the Bosch book. They're still fully mechanical, it's just a sensor that gives an input to the ECU when the needle operates. That's the ERR3337.

But the other three just look like plain mechanical injectors

Buy four Bosch 0 432 193 835 injectors for a Tdi,there $100 per injector cheaper than original. Pat

Not around here Pat, the local Bosch diesel 'specialist' after much ****** around finally gave me a quote.... $115 more per injector than you paid in Kal...

What's the difference between the ERR3339 ones and the ERR3348 ones?

dunno ?

Could be any reason, different spring pressures, different tip/ nozzle profile, different bleed off passageway? The other injector is the signal injector that is fitted to number 1 cylinder, it sends a signal to the ECU in conjunction with the crank pos sensor to help determine injection timing and duration etc

Yep, late Nissan RD28T's in GU Pootrols are the same. Its a kind of Claytons electronic injection thing, you know, the EFI you have when you dont really have EFI!

A bit more research reveals the ERR3348 ones are for 17L/19L 300Tdis, I don't know what that means, but I think mine is a 20L.
