BOSCH EDC15 ENGINE MANAGEMENT SYSTEM
Introduction:
The EDC15 is a much used ECU in "semi-modern" diesel cars like golf 4 TDI from 2000 on. It is
used in much more cars, but in the example's i give i used a 150hp golf 4 TDI. Winols is used to
change the maps. Some EDC15 ecu's do have more software banks, in my case there were 2
banks of software. There is only one of the two active at a moment but i decided to change
both banks. Some ecu's have even 3 or 4 banks. So just to be sure, change all banks exact the
same (Winols will do this automatically).
Map explanations:
The different maps of the EDC-15 can be grouped in 2 groups. The fuel related maps and the
turbo related maps. As the name says the fuel related maps control the quantity of injected
fuel, and the turbo maps control the turbo pressure. All examples in this document are taken
from an original VW Golf IV TDI PD 150hp.
Fuel related maps:
-Drivers Wish
-Torque limiter
-Smoke limiter
-Duration map
-(EGR map) not really a fuel map, but have to put it somewhere.
Turbo related maps:
-Turbo map
-N75 map
-Boost limiter map
-Single value boost limiter
