BOSCH AUTOBOX G58 87.0 ENGINE MANAGEMENT SYSTEM OVERVIEW

 BOSCH AUTOBOX G58 87.0 ENGINE MANAGEMENT SYSTEM OVERVIEW

Manufactured by Bosch, this ECU appears to compliment the Motronic M5.2.1 Engine

management system. Not being Flash Programmable, there are two near identical systems sub

numbered .0 and .1 with the main difference between the two being different shift points,

different Gear lever switch inputs, and current gear indicator outputs. This version was fitted to

all Automatic versions of the Discovery series II. It is an adaptive unit, which means that it

learns and stores the driving habits of the owner and adapts to suit their driving style as well as

overcome variations in engine power, etc which can be reset with this module. This ECU does

support some OBDII compliant fault codes as well as a large number of codes outside of the

standard which this module accesses.
