Learn PDE: A Beginner's Guide

Hello,

I've heard a few times that after replacing the PD (e.g., on a 1.9 engine with 115 hp, manufactured in 2000), the PD needs to be somehow "linked" or "calibrated" to the engine control unit (ECU).

What's actually going on there?
Thank you!

With this model? Nothing.

I am familiar with the concept of 'training' PDEs, but in a different order of magnitude for the PDE.
The 'big brothers' of PDE, the truck plunger injection pumps with PLD control unit, are manufactured in various tolerance groups.
This means that the different injector pumps inject varying amounts of fuel for the same injection duration. To ensure proper injection, I now need to take this tolerance into account.

In PLD, this is done using the pump characteristic curve.
This is the 'pairing' process for the submersible pumps.

The same principle applies to CR injectors.

Probably not for PDEs at VAG .

Best regards, Jochen.

The 1:1 exchange works without any problems. If you want to install larger ones (520 or 550), you should consider a software adjustment. There are different versions and configurations that may be difficult to make compatible or may not work at all. (For example, PDE 1.1 to 1.3). It might also work, but possibly with stuttering or uneven running.

I now need a software adjustment after installing larger injectors. I have contacted several tuners and received conflicting information.

Therefore, here are some questions regarding software customization:
- What needs to be changed?
- How long does the adjustment take? (I've heard it can take between 3 and 5 hours).
- Does the entire EEPROM need to be re-flashed?
- Does the immobilizer need to be reprogrammed?

Thank you for the information.

Very simple:

Call Rainer, or email him. He's the owner of this website. He's the only one who can help you, because we don't offer support for other chip tuners who might not know what they're doing, even if they try to profit from it!

Hello Matthias,

I contacted the homeowner first. Unfortunately, he declined the job for certain reasons that I can understand. But now I need to find someone who can help me.

I asked three different tuners, but I received conflicting information!

That's why I asked those questions earlier.

Sure, here is the translation of the text from German to English:

"Gr."

"Gr." is an abbreviation for "Greetings."
