Title: Vehicle Sensors to RAM data
Post by: Cadensdad14 on November 01, 2018, 04:15:35 PM
Im interested in adding a couple sensors to my 1.8TCH me7.5 ecu, specifically a EGT sensor and a Turbo Shaft Speed Sensor.  From what I understand, the data module and hardware for an EGT sensor is standard on all 7.5 ecus and just coded out.  Theres nothing related to the TSS in any of these cars.  I know someone has fed a E85 sensor into the ecu using the rear O2 sensor, or something similar.  Ive got a decent handle of assembly programming.  Does the ecu read the sensor and write it directly to a RAM location or what is the process involved?  I know its a basic question so if someone could tell me the name for the process i can chase it down on my own.
