Cipher can adjust the idle +/- 250RPM. I'm sure other can as well.ThePainClinic wrote:I have a 2010 PF LE 4.0 and when I'm at a stop light and the A/C is on I have noticed that when the compressor kicks on it drags the idle down to around 500rpm. It can shake the car a little and creates a sound when doing so. It goes right back up but then drops again, making it a distraction. Ive called several different service dealers who have all said that's normal for Nissans, especially the PF/ Frontiers (I assume the V6 engines only)
My question is can a tuner (Nissan Cortex 4950) bump the idle up a 25-50 rpm's. The dealer said they couldn't play with the idle against Nissans rules. And that everything was normal. But its so annoying is there anything I can do?
Same here. Might be the V8 ECU might differ.DanJetta wrote:I feel like your idle should adjust automatically to compensate, no? My past cars' idle would dip for a second and then recover. On my Pathfinder, the compressor actually has zero impact on idle. Possible vacuum leak?
I agree, it really shouldn't be an issue. Also, it almost seems like a band aid for a different problem by adjusting the idle speed.eieio wrote:if a tuner is used to bump up the idle speed, wouldn't it have to be readjusted back down every time the A/C is not being used?
it seems to me that if it weren't, it would be a pretty hard & klunky shift from park into the forward gears or reverse
BTW: the A/C kicking on has barely any effect on the idle speed of both of my R51s
