For those of you new to reading programming 101, please run an
archive search for this, and read all related subject matter before
using any of this information.
Previouly we talked about WOT timing, and fuel. Included in these
must be meet parameters are, a min rpm (bypass), and a sometimes used time
delay.
In use they function like this. Say you have a rpm bypass of 2500.
This means you have to be at 2501 rpm for WOT to be enabled if
there is a time delay entry, and you have meet all other enables.
If you have a time delay of say 5 secs., If you meet all the other enables,
but are at 1500 rpm, and it takes you more than 5 secs.
to get to 2501 rpm you will execute WOT after the timer expires,
even thou you haven't reached 2501 rpm..
The bypass rpm address is 02CC, and the time is 02CE.
Now, why in the world would you even want such things. Believe it
or not they do help under certain conditions. While in a very light
high HP, high stall converter application, you would turn the delay to
0.0, and rpm to 800. But, for rock crawling in a 4wd heavy vehicle,
you don't want to light the tires, as you ease into the gas. So for
that you might use 2500, and 5 secs. Also, it makes life easier on
the transmission. The tranny can't react as fast as the engine can,
so you can have too much HP, before the line/govenor pressures
have built to handle the load, and under those conditions the tranny
life is quite short.
Again, this is how I interupt things to be. I am not a EE, ME, or
software person. If you see any errors in the above please e-mail
me, and let me reveiw, you statements, rather than risk generating
lots of confusion. Also, just use a short clip in your response please.
