due to a knee injury i wont be working that weekend now and is a very good chance i will be down there for the dyno day. i pmed ron already but does anyone here know anything about speed density and how to tune with it.
Tuning is not a whole lot different than a MAF based system. You are referencing manifold pressure instead of a mass flow rate. Air temperature is it's own map. Why are you concerned with speed density?
because my tuner and myself are loading a map that was taken from a group n rally car and it no longer looks at the maf its all based off of speed density. he loaded the map and without really doing much leaning out or anything put up 30 more whp and 20more wht
This discussion does not belong in the event thread. I created a new thread for you. Regarding your question, here's some links with some reading. Enjoy. http://www.romraider.com/forum/topic5327.html http://forums.nasioc.com/forums/showthread.php?t=1865156
I've been playing with speed density. If you know how to play with the MAF scaling, then the speed density should be no different. Switching from MAF to MAP.
sorry was ment 2 be a quick question related to the dyno day not a really a thread but will keep that in mind for the future thanks.
It is related (in theory) because you are talking about a tune... but you can do that with most things Subaru .... but it is not related because that thread is an Event thread.... which is just related to going to that event.... see the relation.
The groupn rally ecu doesn't really have much knock control. FYI .... I am runnng it and it is much much more responsive.... If you just downloaded the map and reflased it without tuning I am sure your a/f ratio had changed btw... The whole fuel map pretty much asks for 12's ect.... There is a cell that won't go away also if you run this map....
been running it for a day now love how smooth everything feels. will continue to work with the tune hope to put up some good numbers come saturday for the dyno day.
