Javisupra Posted May 18, 2021 Report Share Posted May 18, 2021 Necesito ayuda con el ventilador. Si hago la prueba funciona perfectamente, pero cuando llega a 93 grados, el ventilador se enciende, pero hasta que pasan 5 o 6 segundos el ralentí no acelera, por eso mi ralentí se vuelve muy inestable. ¿Le ha pasado a alguien lo mismo?

Adamw Posted May 19, 2021 Report Share Posted May 19, 2021 Ok, possibly 3 problems. Firstly, Engine fan 2 is set to 0°C, this will have an effect even without a Engine fan 2 aux ouput assigned, so this means the idle fan step is always active. I suggest change Engine fan 2 & 3 temperatures to 120°C, then they wont interfere. Example below. Secondly, stepper motor idle valves only move quite slowly, so they dont often compensate well for fast load changes such as fan turning on. It is best to use idle ignition control to help with this. Some suggested settings below which should be a good starting point. Thirdly, your battery voltage drops from 14V to 11.8V in some cases when the fan turns on. The lambda shows very lean at the same time, so this may indicate your injector deadtimes arent accurate. This voltage drop may just be related to the RPM dropping so may fix itself if the adjustments above stabalise RPM. But if battery voltage still drops a lot when fan turns on then it may suggest there is a bad ground somewhere. You may need to experiment with injector deadtimes to improve lambda stability.

Now when the fan works and with the lights on, the car continues to work. Thank you Log 2021-05-25 7;45;37 pm.llg javisupra.pclr Quote Link to comment Share on other sites More sharing options...
