Please HELP with engine live data readings.
Hello everyone. I have some "performance" problems with my w210 e55 amg. Can anyone here post me some engine live data readings from stock or tuned e55 ? I need current values
Ignition angle in various driving conditions(cruise, max acceleration...)
MAF reading in KG/H
02 sensor in MV
Thanks in advance !

If you're using an OBD scanner with Live Data capabilities,the readings should be similar with other cars,I agree though that sometimes they vary on different makes.
The O2 sensors should be switching between 0 and 1 V in Closed Loop,the TPS should be ranging from about 5% at idle to about 90% at WOT(I don't remember on mine if it ever got to 100%). I don't remember the MAF readings,but what's more important,check to see If it's reacting to different TPS positions.
In a car that is believed to have performance issues the most important 2 numbers I would watch are my Short and Long fuel trims,because those will tell you what the computer is doing,whether it's adding too much fuel or pulling it away. You want to have those nr as close to zero as possible.

I'm using carsoft to monitor my engine data...
Yes my long term correction are 1%, my TPS reads 100% at WOT and the lamda reads 850mv at WOT which is all great.
But i discovered my problem is in the advance timing - every e55 that i read with carsoft keeps 15* at idle and 27-29* at WOT while my car holds 7-9 at idle and 20 at WOT...Any ideas what can cause the problem ?
