Rossobianconero Posted May 17, 2020 Report Share Posted May 17, 2020 when you say below 110, are you taking about actual engine temperature (C?) or are you talking about vehicle speed? either way if you post a log and the rom file from the ecu we can have a look.

Adamw Posted May 17, 2020 Report Share Posted May 17, 2020 If your engine temperature climbs with road speed then it would suggest your cooling system is inadequate. Quote Link to comment Share on other sites More sharing options...

But if i drive my car more then 3 hours with air condition and vehicle speed below 110 temperature is perfect but if i drive 120 temperature goes high with and without ac Quote Link to comment Share on other sites More sharing options...

The only thing the ecu can do to affect coolant temp is turn the fan on or off. Obviously at 120kmh the fan is not going to make any difference.

Does the fuel do engine temperature coz i have rich fuel Quote Link to comment Share on other sites More sharing options...
