I have been told by a member that my MAT/TPS grid is no good and my motor can't be tuned. Every one that I peak at from other members is blank. What is happening?
I used one from the latest firmware default, but it is forcing me to re-tune at different times of the day - to extreme? WTF? I am in a HUGE hurry.
Can somebody PLEASE point me to a plausible MAT/TPS grid file?

Thanks!
I have the same problems.... runing autotune in the morning going to work..... everything is perfect...... but logs shows me that I way (5-8% ego) to lean going home in the afternoon
put 100% in from 20 to 60 deg... to start, then re-tune VE.
The Ideal Gas Law (which is what the table is filled with by default) never works right... and makes tuning a mess.
My theory is that it's not just air temp specifically, but it's heat soak of the sensor so the compensation done by the ideal gas law cannot be applied because the actual air temp is not as hot as the sensor is telling you it is.
Ok so we need better sensors....
I have tried with no mat compensation at all..... now there you talk about a mess
If you place the IAT sensor in the pipe just a little bit before the throttle valve you will get rid of the heatsoak problem.

It's not the sensor (usually), although a fast acting/open element type does help. The issue is heat soak of the sensor (usually due to location).
I don't really seem to have any issues with 100 between 0 and 60 deg C... nothing that the O2 correction can easily handle anyway for the most part.
Ok im running this type throttle body and sensors..... could move the sensor to the pipe just before throttle..... what sensor would you recommend as the fastest sensor

I've had good luck with the open MAT sensor from the web shop actually (or similar like 2.7/1.8T sensor from VAG engines).
This on ?

That's the one!
