well I'm pretty lost on what slew is and how you can make it work to your advantage... like a "slew rate 101"
I asked about this on yb and pretty much got the same thing out of it.10secBu said:I haven't used one, but here's my understanding of the MSD digital 7 programmable.
It's got two potential "traction control" functions.
1. timing retard which is fully programmable to amount taken out, how long to bring in 100%, and the agressiveness of the curve.
2. Slew rate. RPM limiting just like the rev limiter only you set a curve which mirrors your engines excelleration rate that way if the tire spins and rpm wants to spike, the limiter will hold it's rate or excelleration.

If I'm correct what you'd do is get a data logger and you can see where you have tire spin. Then in that rpm range you can set a rpm limit and if the tires spin and the rpm's trigger the function it will retard timing to where you set it to and slowly ramp back in at the rate you set to bring traction back and apply power. What does the word "slew" come from or mean in the ignition world?
It sounds very confusing but I think if thats the way it works it's quite cool, but with n2o and your timing retards in that department of the box things will really get tricky. I'll try it.
Todd, you run a logger right? Which one and how expensive does it get just to be able to detect and read tire spin, and that same box can record a wideband also right?
