Intercooler Air Intake Temp Vagcom Testing Results

[Sirocco20348]

Hey Guys,

I thought I would start a thread with people posting up intercooler Air intake Temp Logs. A lot of people are wondering what intercooler cools the best.

I went out this morning to do some logging of my car. Ambiant air temp was 27 degrees celcius, humidity 28%.

Car: VW Golf IV GTI
Tune: Custom Code Stage 1
Turbo: K03
Intercooler: Stock

The car was well heated up before hand. I did 4.5 runs, WOT through 2nd and 3rd to around 6000rpm on open road.

As expected the stock IC would be average on the track, as air intake temp were 33 degrees above ambiant temps.

But still for stock I think that it pretty darn good! It was also interesting to note that the coolant stayed a rock solid 90 degrees.

How to do your own testing

Most people would be intimidated or not prepared to spend the moneywhen it comes to vagcom, but its pretty easy once you have it all set up. Hopefully this inspires more people to run some of there own tests on their intercooler setups.

1) Buy the full product from VagCom or if you are struggling student Buy a VagCom clone cable from ebay.

3) Make sure your using a computer that is running Windows XP. If your running Windows 7 then that is no problem you just need to setup a WinXP virtual PC. Follow Instructions here.

2) If you have the legitimate version of vagcom, then download the latest version and follow these instructions.

Keep in mind that the instructions use a 2.0L as an example. Since we have 1.8T's, we need to look up the '06A-906-018-AGU' label file to understand what measuring blocks to use.

Also when you want to map boost pressure, since othe AGU does not have a MAP sensor, the following is a work around. Log both maf and rpm, export to excel and calculate as follows: boost pressure in bar = ((maf*53.47)/rpm)-1). Do the conversion to PSI afterwards.

3) If you have the ebay cable and a copy of VagCom 409.1, PM me and ill let you know how to get it working and give you the label file if you cant already find it on the net.
