VAG-COM monitoring blocks

[zemun2]

If I was gonna tune my car what monitoring blocks should I look at and what the normal operating parameters are?

Example: block 20 Ignition angle retard should stay within 3-5°KW but you can safely go up to 7.

not too sure but isnt it just timing, boost levels, egts, knock sensor voltage....im sure theres more to that

My point is I need specific numbers like:
block 20 range 3-5 not to exceed 7

sorry you'll have to ask somebody more knowledgable than i =)

Look at your knock sensor voltages... anything over 20vdc is considered to be "knock". If you're seeing voltages from 10-12ish, you have much more room to PUSH the car (as well as boost). Timing-wise, your car should adapt and learn, but since you're running REVO, I dont know how their timing maps work on their units. I would ask a "REPUTABLE" REVO expert.

The measuring blocks I use is 115, 119, and 26 if I can remember off the top of my head.

Block 20 is a good one. You want to check out 1, 3, 4 as well. You should see a g/s reading maxing out at 187-190 meaning you are flowing at the max amount of the maf. Most people with chips probably are. The Lammda value ideally chould center around 0 but it as acceptable to be between -5/+5. This is the amount of fuel added or removed (ie running rich or lean) from the stock parameters. A car that is adding or removing more than 5 is not properly tuned.

Hey Mike,
What block is the lambda at?
Thanks a bunch for the info.

Off the top of my head I forget, but I believe it is channel 1. If not it is within the first four channels. Just scroll through, you cant miss it. cheers! mike
