The operation of a TDI

[prj]

Yeah, driver's wish is just torque and everything else is calculated based on it... kinda like ME7.
I haven't looked at EDC17 much though

I can give you a file for a T4 with the AJT Motor if you want. But you have to do immo and checksum cause i don't know how ;-)
(perhaps prj can do it)

Yes Please

I drive a 2003 AJT too

cheers

Hehe me neither. Looking at Delphi manuals all day (to make future challenges for you to sort out ) so no urge to do so in spare time.

ME7 keeps on being mighty interesting though... perhaps giving it a try in the future.

[prj]

Guys, if you want to trade files, that's fine, but don't do it in this thread.
I really don't want "omgwtf my car does not start" stuff in here
Don't get me wrong

Pretty much all the ME7 factory info has leaked, so it's just a question of sitting down and reading through ze german.

One of the few people I will take chip tunning advice from is you PRJ

As a novice to this the route I will go down is to get an identical ecu from a brakers yard and have a play with that. That way I can always put my original ecu back in if it all goes wrong.

If it has immo, you will need to adapt immo or defeat it first.
The former should be possible using a VAG-COM cable.

[rj scotty]

Now Vagcom I am fluent with. I also have vag tacho so I can discover login codes.

Time to take the next step, maybe

[prj]

Yup, then you are covered - go for it

[rj scotty]

Sorted

Rich exits stage left to hit ebay for a t4 AJT ecu

[kaross]

Yes, it's a tuned file. You can look at it if you want. I use it in my T4 TDI for at least 60'000 km. It don't destroys motors ;-)
But it's from the bay, so i don't know if it's correctly tuned. I sent the original file and then received the tuned one from the "tuner".
No soldering was needed.

I can check your file and answer in this thread. Mostly ebay chips are crap. Car maybe is going better but you can get it run better.
This ECU is much more complex than Omega.

EDC15 is still so easy compared to ME7...

Omega has ECU from 1994 basically. Or well, even earlier. MSA-11 is ancient

[kaross]

By the way MSA-11 is the first electronically controled diesel injection.
Diesel injection systems having an electronic volume control, start-of-injection control and exhaust gas recirculation.

Right now I am reading one document from Bosch about ME - management. tough nut.

[prj]

Yup..
It's very simple and elegant. Good place to start learning about Diesel electronic injection

Btw, actually my topic title is incorrect, because this engine is not actually direct injection.
I was thinking about Audi's too much when I wrote TDI, as Audi's AAT was the first TDI...

[kaross]

not exactly. Audi 100 1T in C3 chassis was first TDI. AAT, ABP was after that.
Opel is prechamber diesel.

Ah yeah, I forgot about 1T completely.
Indeed, Opel is indirect injected. BMW engine... or Steyr, if you want to be really **** about it
