edc15 with two mods-help

by **eazydaz** » Sat Apr 06, 2013 6:49 pm

I can replace flash 29f400 with flash 29F800 and I can two mods in one flash,please,with which pin on flash is for switching momories in flash? or can you write some manual for switching two mods in one ecu?

ecu is EDC15VM 1,9tdi ALH

Hi,

I was as careful !
In the laboratory, I have made with a discarded, but fully functional EDC15C7 this experiment.
I replaced the 29F400 BT 70 by 29F800BT 70.
Also important is the addition of "BT - Top Boot)" and the time of 70uS should also agree.
Connected to pin 2 (A18), and the pin 12 (chip enable).
This one need a flip-flop (eg. HEF4013B), so you can switch under load.

All attempts have yielded nothing, because obviously the boot matrix of 29400 is different from that of the 29800. :( I have no solution.

I have then two 29400 soldered directly above the other, and at pin 12 (chip enable) via a logic circuit (HEF 4013 and CD 4071) driven.

So it worked out.

I have made pcb and installed it in the ECU edc15P. 2 x 29F400
The switch +12V

maybe it is possible to do it by a DW map in EDC15 are 2 DW maps but i dont know how to switch between them. I write a mode for my hdi with 2 different DW maps but only one is on :?:

WTF?
Have you ever had a single look into the EDC15C manual at all?!?!
Mine clearly says that there are two turbo maps for ordinary driving and for sporty driving and that the system calculates a value between those two.
For other maps, it is completely well explained how the ECU behaves and why it uses them at all.

Why nobody has a SINGLE look into the " Software-Funktionsbeschreibung EDC15C B079.CC0"?
Especially when it's freely available and explains completely everything about the function of the EDC15C?!?!?!?

Why does everyone simply WANT to keep on guessing?!?!!?

Tell me which section of the manual you need to explain and I will gladly help!

Is it "3.1.6 Wunschmengenbildung" or some other?
Or "3.1.9 Begrenzungsmenge
Die Begrenzungsmengenberechnung ermittelt gemäß folgender Abbildung die zum aktuellen
Betriebszustand passende maximal zulässige Einspritzmenge."?

Or 3.1.9.1 Rauchbegrenzung?

For example, the image is just the calculation of idle speed, not the control of idle speed, but a calculation of how much should it be!

So, what would it be?

Are you thinking on proper boost pressure control to allow in more air? There is a whole section on that!
