Data Logging

[CHRIS200]

How do I go about doing the data logging on vag-com to get the performance figures like bhp, torque and boost pressure??

Where do I go and what do I need to do??

Have a look on this site http://www.ross-tech.com/vcds/tour/logging.html

Its full of info on using VAG-COM and if you look here: http://www.ross-tech.com/vag-com/cars/index.html

As "Useful of site links, there are some spreadsheets that help you to visualise what you have logged.

Hope this helps mate...

P.S. As you are remapped, the BHP spreadsheet won't work. It doesn't take into account the new torque values of your car that it needs to refer to.

Thanks Rob

Chris...

You need to log the following groups:

002 - MAF
115 - Boost
120 - Torque

I hope that helps.

Thanks Scott.

How is the best way to log. Drive in each gear and log the data around to the redline??

I do have a spread sheet that will do the conversion into bhp, lb/ft and psi etc.

Find a nice long quite road... 4th gear, 2000rpm... hit 'start' and put foot flat to floor until you clip red line then hit 'stop' ..

Then post the logs up ...

Can you send me a copy of the spreadsheet? - I dont have this ...

Log 003, 118, 115,020, 031, and 032

Do no more than 2 at a time to get any reasonable samples.
003 and 020, then 115 and 031, then 118 and 032.
This gives you, airflow, actual timing, timing pull, requested boost, actual boost, target air fuel, actual airfuel, n75 duty, inlet temp, actual boost, and then finally fuel trims.

Nice info there Dave...

I could do with logging the fuelling as well...

Thanks for your help on this guys. I did a log on my mates LC and we got some results, don't know if they are any good though.

Also converted the data into the spread sheet that I have and we got our own power graph.

Put the logs up and we'll tell you...

Where did you get the spreadsheet from mate to be able to put your logs into for any graphing etc?

You can download some from the Ross-Tech site or make them yourself.

I did both.

dont suppose youd forward them to me would you please Rob?

 

[longman]

PM me your e.mail address and I will fire them off to you

I guys, I know this is a real blast from the past but I have recently got my hands on a copy and want to start logging my car. I did a search around the site and found this to be the best at explaining why and what I need to log so thanks

Now time to go for a spin!!
