Hi

Have a Syvecs S7+ on a Honda k24 when cold it idles perfectly but once the fans comes on 2 or 3 times the idle starts hunting till it stalls. I can start car fine straight away it will idle sweet until fans come off/ on. Any idea what could be doing this. Thanks

Any number of things

From bad idle control setup, bad voltage swings due to the load, wrong injector data for battery voltages and the list could go further.

Datalog all relevant parameters and see what is going on
