#VCDS MEASURING BLOCKS LIST HOW TO#

Note that seeing numbers higher than 0 does not necessarily mean your car is running dangerously rich or lean just because of a little correction. The computer can correct for these rich and lean conditions up to 25% or so. No fuel is having to be added or removed to maintain harmony. This means the car is doing what it has been asked to do. The numbers will be displayed as a percentage starting from 0% indicating NO fuel correction is needed. This is a fuel correction table used by the computer when it senses the car richening and leaning from the programmed air/fuel tables. Any lifting of the throttle during the run will result in inaccurate A/F numbers for the purpose of our evaluation.

Note: In order to have a log that will be valid, you will need to see at least a 3rd gear wide open throttle run from about 2500rpm until redline. VAG-COM Datalogging for MY2001+ Audi/VW Vehicles.

Here is a good thread that Jspaz put together on vendorzine.Vag-Com Reference Page - Note that if you are unsure of how to execute logging functions please see the following page on this site. It really depends on how crowded the track is or isn't.ДЄgain, make sure to hit the turbo button and check of the group uds requests box as it's critical and easy to forget. I usually make a few passes in a row save the file, let the car cool down and repeat. Whatever, you do DON'T shut the car down w/o first saving the file otherwise you can potentially lose the file. What I do at the track is get everything setup and then I just have to hit start right before I make a pass and then stop right after the pass. 014503774 This is than your boost in psi. There are many other fields we can go over but these are where you should start and will tell you a ton about the car.ДЇor converting the hPa #'s to psi you take the hPa value and subtract the ambient value you wrote down from it and then multiple that value by. is the temp of the intake air, and charge air pressure specified is how much boost the tune is calling for and this is your upper limit so to say. accelerator position shows when you are WOT, engine speed is rpm, IGA_AD_KNK are the individual cylinder timing retard values so you can see if timing is being pulled, Ignition angle is your total timing, Air Mass is the volume of air going into the blower, intake manifold pressure is your boost levels in hPa, RFP_AV is your boost bypass valve stated in percent, Intake air temp. Again, the # of the field may be different but the Here are the fields I then select while logging. You'll use this later to convert your hPa boost number to psi if you desire and I'll go over that. When you first log on look for ambient air pressure and select that. If you don't do either of these the sampling will be very poor so again, it's critical. A very key step that I'll mention now and later is to choose 'Turbo Mode' and also check off the box in the upper left called 'Group UDS requests' This will give you the best possible sampling rate. You can log up to 12 but the sample rate is slower the more you choose however it is still decent even with 12 so log what you want. When you login choose the following -> engine controller button -> advanced measuring values -> then you'll need to choose the various fields you want to log. Again, it's easy and if you have questions just ask or make a post and others will help also. I'll also put a link from a thread Jspazz made on AZ with pics of how to log but I'll walk you through it as well. I'll give you the field names and numbers but depending on the version you have and they change frequently when RossTech does updates the numbers may not match so look for the names more so. Here is the rest of primetimes email that might help you: A lot of your timing pulls from knock occur at low RPM, which is surprisingly the easiest situation to create knock (low RPM/high load). I'm no expert with reading logs but it looks like you have a bunch of snap shots, would be better to get a continuum as you rev out. Selecting LOG on the last screen will prompt you to enter a file name before logging.I do not think you should be logging these in 4th gear till redline. Here is how you navigate through VCDS and Save Files: Do not enable the kick down switch on S-Tronic vehicles.Do not lift the Accelerator before the end of the run.Put the Accelerator all the way down for the entire run.Finishing RPM 7200 RPM's or fuel cut off/gear shift.702 - Boost Control Valve AngleTo log the car:
