Is there a way to convert the voltage output of the temperature sensor into a temperature reading?

Does anyone have any preliminary data?

'Thank you.'

Hi.

If you have the same input stage in your engine control unit (ECU) as I do, you can roughly estimate the voltage at the sensor relative to ground as follows:

4.4 V = 0°
3.9 V = 20°
3.2 V = 40°
2.3 V = 60°
1. 5 V = 80°.

Interpolate Pi x Thumb.
That should be enough for the intercooler.

cool thx! icon_lol.gif

What would be the ideal intake timing at the engine's intake valve? 30 degrees?

Sure, here's the translation:

'Thank you.'

All I can say is, the colder, the better!! icon_smile.gif

No, that's not correct... because eventually, the diesel won't ignite properly anymore... so, give me a number... icon_smile.gif

Sure, here's the translation:

'cu' is a Spanish abbreviation for 'cuánto,' which means 'how much.' It's often used in online communication and text messages to ask for a price or quantity.

Hehe icon_biggrin.gif
'However, I believe that with the temperatures we experience here in Europe, there should never be a problem with misfires due to low temperatures. At most, it might be an issue during starting, but even that is no longer a problem in the age of direct injection!!!' Only the heat output is really bad in the winter with the diesel model; it sometimes takes half an hour to get the car warm. icon_smile.gif

Hi!

With a compression ratio of approximately 20 to 1, the temperature in the combustion chamber increases to over 700 degrees! The lower the intake temperature, the more air enters the cylinder. There is always enough to ignite the mixture. The colder, the better.
However, your engine control unit reacts to the outside temperature. Our TDIs perform significantly worse above approximately 15 degrees Celsius. We haven't yet found a reason for this, but it seems the cause lies more in the behavior of the engine control unit than in the cylinder filling. With your larger intercooler, you may not necessarily achieve a performance increase. Compare it to a drive in light rain, where cooling is optimal. You don't have any more Nm left either.

Best regards,
Uwe

It's not necessarily about a larger LLK (likely referring to a specific product or component), but more about a more efficient one, with a larger surface area in the front while maintaining the same volume, etc.

How about a copper heat sink? I've seen them before.
