you can also set it from your transmitter if you have a good one (4pks, M11)

Default Throttle Curve

I have the software installed a field link card and the usb hook-up and have been through all the diff parameters,I have saved all my settings to the MMM and created e-files and printed.
I don't quite get the curve setting in relation to real time driving. Been to numerous forums and a bunch of searches. I would like a guide to making throttle curve adjustments

This is a great question. I would like to understand the throttle curve, how it relates to my SC10, and how to adjust it.

what a change in the throttle curve does is change the amount of throttle output in relation to the trigger position for a given moment in time. in other words, normally you have a straight line for your throttle curve. when you pull your trigger to 50%, your speed controller spins the motor at 50% power. you can alter this curve so that maybe you only want 35% throttle at the 50% trigger position because you find that you dont need as much speed for a given track. it allows you to change the throttle output to something other than a straight line curve in relation to the throttle trigger position.

im not sure if that makes sense or not.

makes sense to me...you can also adjust the brake curve as well

yes you can. maybe thinking about it in terms of an rc helicopter may make it easier to understand. if you use a straight line throttle curve you cant fly upside down or inverted because as you drop the collective you also drop the blade pitch. by altering the throttle curve into a 'v' shape as you go past 50% the throttle will start to go back to 100% so you can have high blade speed but be in negative collective range.

that may have made it worse, sorry

sorry. if i had some curves to put up i could explain it better. changing the throttle curve allows you to dictate how much throttle you have at each trigger point. nevermind, i suck at explaining stuff.

Ok, let me get this straight. You can set the MMP throttle curve in correlation to the throttle trigger throw? ie. if your car or truck was loose you could adjust the throttle curve to start out slower to avoid wheel spin? Is there anywhere this info could be found online?

Yes.

It is the same as using EXP (expo/exponential) on a decent radio.

It is usually used to smooth out the initial thr/brake throw on your trigger.

Is one better than the other or is it 6 of 1 and half dozen of another?

I am willing to bet they come out about the same. I have always used the one on the radio since i can fine tune while on the track and dont have to plug/unplug the esc every time to change something.

It may feel a tad different thru the ESC just like i have found with braking. It seems to be a little smoother/consistent on some ESCs if you program brake power directly.
