BOSCH AUTOBOX G58 87.1 ENGINE MANAGEMENT SYSTEM OVERVIEW

 BOSCH AUTOBOX G58 87.1 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 the P38 Range Rover after the 1999 face lift / revamp. 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.
