Hi,

I've learned a lot from this and other tuning-related websites and decided to put some of this information into a guide.

This guide is centered on VP37/EDC15VM+ cars, but many concepts like linearisation, diagnostic extension, IQ limits and such are applicable 1:1 on PD cars.

It also contains a section that deals with hardware changes - what's necessary to reach what power level, stock hardware limits (for VAG 1.9 TDI cars), original files, damos, and many other things.

However, it is not a guide to copy/paste from - you'll have to think for yourself

After all, it's supposed to make you learn something!

The guide isn't 100% finished, nor will it ever be - there's always more info to be gained or included. I'll keep this thread updated when I release a new version.

Comments, corrections and additions are very welcome!

BTW, you can also find the ori file the guide is based on along with a cheat sheet (all map addresses) in this thread here on ecuedit.

Kind regards

Hi,

I've done a little more work on the guide.

Additions
MAP-based smoke limiter hints
extra idle speed maps/singles

Changes/fixes
small things here and there, nothing major

Regards

Very good!
Thanks a lot!

I would like to see that to but i still don't have the permission because i have not enough post. Could you maybe please send it per PN?

Hope you managed to download it on your own, it's not THAT difficult

In any case, I've corrected some mistakes about MAF-based smoke limiting as well as added new info about temperature-based IQ and smoke limiting, which can be very useful.

Also worked in some more information about turbos, actually links to the turbo guides by Garrett which I very much recommend.

At this point, I've researched and found out pretty much all I wanted to about VP37 cars (or know about so far) - so if anyone has questions or other interesting things to figure out, don't hesitate to ask.

Regards

@ Nexus:

Your guide seems to be very helpful if someone is new in ECU tuning (like me ). Since I am reading about EDC15 now to get familiar with, i saw that there are some types of EDC15 version, namely:

- BoschEDC15P (should be Pumpe-Düse?)
- Bosch EDC15V
- Bosch EDC15VM
- Bosch EDC15VM-1 M

Could someone explain the differences? Are there different maps concerning the above mentioned versions or is there no difference in ECU tuning?

Thx!

Hi,

thanks!

The EDC15V/VM/VM+ are for VP diesels, the EDC15P is for Pumpe-Düse diesels.

Then there are EDC15C versions for common-rail diesels, as well

Basically, they are not that different in regards to maps and layout, but are different in hardware in some ways.
