How long of a time duration would be needed for a cool down timer. I thought maybe 1.5, 3 & 5 minutes would fill most needs. Any thoughts or comments?

In most situations 1.5 minutes is long enough for a cool down timer. The main thing is making sure your exhaust gas temp are below 400 at shutdown. I watch my temps and usually only takes about 15-20 secs to reach that with highway and city driving. Mainly use my timer if I am going to run in store real quick anymore.
