Understanding EDC15 Multimap: Performance on Demand For enthusiasts of older VAG (Volkswagen Audi Group) diesel vehicles, the Bosch EDC15

Valet/Anti-Theft: Drastically reduced power or a "no-start" map for added security. edc15 multimap

A Multimap modification alters the software structure of the ECU to hold multiple sets of these maps simultaneously. Instead of having one static tuning file, the ECU holds 2, 3, 4, or sometimes 5 different tuning files stored in its memory. The logic: A

The logic:

A. Physical Analog Switch

The simplest method: Connect a 3-position (or more) rotary switch to a free analog or digital input pin on the ECU (e.g., pin 19 on a 121-pin EDC15P). The tuner writes code that measures voltage via a resistor ladder. Different resistances select different maps. Different resistances select different maps
