Yes, program itself is easy to read and understand. You can download it from http://www.evvette.com/EVVette.com/RTD_Explorer.html
and try running it on your computer. It won't display any graphs or values but you'll get the idea. See Command list under Help-menu for list of possible commands.
I used serial to usb adapter. It was some cheap one found from local computer store. Works fine, though my eeePC doesn't seem to like it. Sometimes it just refuses to work or hangs if I leave it on for a drive (to get some data). Any other laptop works completely fine without hang ups.
Regarding RTD explorer: note default values before editing them. All the programmed parameters will show up when you type config
and hit enter. There is no button to revert back to "factory" defaults. You must also save all the changes you've made. Otherwise they will revert back to what they were upon controller restart. Command save
will do the trick. Before adjusting any throttle endpoint values set current limit to 5 amps (bat-amps-lim 5
) or something like that. This prevents complete motor runaway in case you misconfigure your throttle values. 5 battery amps shouldn't spin motor too fast. Ask me how I know, heheh. Command bat-amps-lim 0
will remove battery amp limit
You'll see your raw throttle values on top right corner. Note the number when foot is off the pedal and when flooring the pedal. Set max throttle value few points off the actual reading so you'll always get full throttle when needed. Same goes for low throttle value. Leave a little play there.
You'll want to make test drive after these adjustments. If it doesn't make any difference you can set t-pos-gain 8
and t-pwm-gain 0
for linear throttle response. After this try experimenting with ki
should default to zero. ki 150
is what I use. The more the quicker controller tries to match output with pedal position. Too much and it will feel jerky. More info on these can be found at http://ecomodder.com/forum/showthrea...ers-15909.html
