Power steering pressure switch effectiveness


Recommended Posts

I'm working on tuning the idle control on my engine, which is an AMG 3.6L M104 engine, using an 80mm Hemi dbw throttle body.  The idle is very stable now, but does dip when turning the steering wheel.  This doesn't seem to be a huge issue, but I'm wondering how effective a power steering pressure switch is in regards to stabilizing idle speed.  Fan step and a/c step are able to make a throttle position correction before either are engaged, as opposed to the power steering step which is reacting to the switch changing state.  Is it worth adding a power steering switch to provide even better idle stability?  How well do they actually perform in operation?

Attach your map, although a PS switch would give more options, there may be an opportunity to improve the situation without a PS switch.  As Ducie mentions idle ign should be able to take care of a lot of this if it is set up right.

I have attached my current map.  I am using Idle ignition, but maybe the values could be better.  The idle dip isn't a huge issue, but if there's an opportunity for improvement, I'd like to get the idle as stable as possible.  Also, please take a look at my anti stall settings.  The engine seems to want to stall unless I give a good amount of throttle input when pulling away from a stop.

Try the attached file.  I have dropped ignition timing down to 10deg around normal idle so there is a little more opportunity to add as much torque as possible with extra timing when needed. 

You may have to increase idle base position numbers a little if it tends to dip too low when coming to a stop now.
