How to: Datalogging Wideband in Romraider

Every person running Romraider for datalogging will need this!

this DIY will make your and my life easier as remote ecu tuning is something that can not be done in Blind.

When we are doing custom remote ecu tuning we require proper data from customer for analisys in order to precisely adjust maps to achieve best results.

keep in mind that your tune will be as good as your provided datalog.

even when remote tuning standalone ecus there should be Wideband figures included in log. otherwise it can not be done in Ray Charles mode - meaning tune can not be done blind.

This DIY is ment for Siemens MS41, Siemens MS42, Siemens MS43 users that we remote tune on dailybases 24/7 all around the world but will work on lot of other platforms as well.

Ok lets get started

there are several ways to datalog wideband in Siemens MS4x ECU's, but i prefer this one

Tools Required: A - Romraider Software

B - INPA K+DCAN Cable

C - Wideband O2 Kit

D - USB to COM Male adapter with drivers

E - DB9 RS232 Serial to Terminal Female Adapter Connector

F - Electrical Tape G - Soldering Iron/Solder H - Wire Strippers I - Wire (about 20 gauge)

Recommended Number of People: - one person will handle it, unless you want someone to hold your beer.

Difficulty: - 2 out of 10 if you've soldered before

Time to Complete: - few hours, but is entirely dependent on having the right parts and where they are in your car.

A) Romraider Logger

Download and install free Romraider software from www.romraider.com

once installed you will have Romraider Logger icon desktop, thats what you need.

What Romraider does: it allows user to communicate with ECU to collect user selected data and record it as log file.

Logging allows you to monitor, real-time, a number of different data parameters used by the ECU in the management of the engine. This is important to track the impact that your tuning changes have on your motor. Logging is crucial to a safe and effective tune.
