How should AFR curve look with RS2 setup~350hp?

[Jonas_R]

Getting my new Zeitronix wideband sensor kit.

And I got some testing todo, but I was wondering how the AFR curve should look from 1000-7000 rpm?

I have been trying to find some information about this on the net, but I cant seem to find anything really specific.

So perhaps somebody has an AFR curve from there RS2'ed s2?

Or someone could point me in the right direction of some reading material?

Cheers

Very helpfull would also be an ignition on RS2 with 350 HP VS RPM VS Boost.

[Jonas_R]

You want me to do that or what?

Well I think the only thing worry about is that AFR is in the region of 10:1 - 12:1 at WOT - there is no specifically correct curve to be concerned with.

I would say that 12:1 is about as lean as you should go.

agreed with paul. maye 12.5:1 but thats on the hot side.

look for 14.7-15;2:1 for cruise and 12:1 for boost.

timing is more complex. timing cools egt so too little will melt stuff. look for around 650 on boost and 700 or so on cruise as a guidline. i have around 40 deg in crusie and bout 22 or so on boost.

hope that helps. remember more timing is more power but also closer to the det line so use the best fuel you can with an agressive map.

Thanks guys I will do a log to when I get my wideband sensor and then post it here. But thanks for the indications, then I have something to look after

The question about the timing was for the user knowing about it but if youre familiar share with us. These logs would also be very good.

I dont know anything about timing But will post some graphs of the AFR when I get the sensor
