Zipperno Posted July 3, 2009 Report Share Posted July 3, 2009 I have installed two electric fans, they are wired so that aux 4 grounds the relay. Aux 4 is set up so that the fans starts at 98 degrees, but when the fans starts also my idle goes full rich Why??? Its like this idles with AFR 14 approx, then it reaches 98 degrees fans starts, then idle AFR goes to 10..... I even tried to disconnect the fans....but didnt help, when aux 4 grounds the realay it goes rich. Should I use a different aux maybe?? //Tom Quote Link to comment Share on other sites More sharing options...

Guest Dave Posted July 4, 2009 Report Share Posted July 4, 2009 What was the problem Dave [email protected] Quote Link to comment Share on other sites More sharing options...
Zipperno Posted July 4, 2009 Author Report Share Posted July 4, 2009 For some reason DI was active, and it shares the same pin as aux 4.... Hasnt started the car yet, but I think that was the problem, Quote Link to comment Share on other sites More sharing options...
Zipperno Posted July 6, 2009 Author Report Share Posted July 6, 2009 I didnt work even with DI turned off.... But when I changed function of AUX 4 from engine fan to engine fan(high speed) it worked!!! Now it idles fine... Quote Link to comment Share on other sites More sharing options...
Guest Dave Posted July 6, 2009 Report Share Posted July 6, 2009 send through a copy of your pcl file i have a feeling there is something setup incorrect with a fuel trim Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...

Guest Dave Posted July 9, 2009 Report Share Posted July 9, 2009 I think you will find that the main problem you have is that there is a trim of 1ms been applied when the engine fan comes on you can adjust this under idle load trims this will not be active when you select fan high speed. also you have the engine fan setup a bit odd this might be because you where testing? engine on temp should be the temperature you want the fan to come on at E.G. 92 deg off hystresis is the temp difference for the fan to turn off at if you put 2 deg here then the fan will turn off when the engine temp is 2 degrees less than the on temp so with an on of 92 deg and a hystesis of 2 deg then the fan will turn off at 90 degrees this prevents the fan coming on and of to much also have a look at your warm up table as it is a little bit back wards you normally have more correction at low throttle opening and less as the throttle reaches 100% Regards Dave [email protected] Quote Link to comment Share on other sites More sharing options...
