Wow,

Video of that controller software looks great!

I feel so behind the times, as I seem to know NOTHING about programming!
Still, I will have to find a geeky friend to give me a hand tweaking my controller!

Guys, what a fastpaced progress, especially the firmware uploads, thanks!
Btw. you apparently didn't lie about your Ford 500 digital gas pedal as seen in your previous "nightly golfkart" video

HEHE, I wasn't kidding, I have connections at a ford dealership. I bought it new. lol. Along with the wiring harness. It was almost as much as the peddle.

There a little expensive, and obviously no documentation, but after taking it apart and doing some measuring and some simulating I was able to figure out what needed to be changed on the control board to make it work without any firmware changes.

I have already made some improvements to the program, and will keep working on it through the day. There should be an update either tonight or tomorrow. It will address some of the little annoyances.

Just to reexamine a question i asked before about my throttle body with the 1.3k to 4.3k range. If i'm understanding the code correctly it should be a matter of just adjusting the zero throttle and full throttle values in order to use this as my potbox?

MPaulHolmes · 10-13-2009, 04:38 PM

Um, yes. hehe. That would work, Jack!

O O O, I can answer that. If you are using the new firmware, with no output. Set rtd-period to 100 to 500. Then leave the peddle all that way up( foot off peddle) that's your max value. Now push it all the way down to the floor. That's your min value. Now do t-max-rc ### and enter the max value you got in the first step. Then repete with min. Type save and your all set!!

Good luck.

Ya know without you guys i'd be just using a contactor to drop 96v across a stalled forklift motor. Digital throttle

What was the plastic you used for an earlier case and what was wrong with it, it looked so good.

Adam,

Thank you to you and your friend Kyle for your excellent work on the RTD Explore program, It looks great !!! and will simplify setting up the ReVolt controller.

I just checked out your website www.evvette.com your new controller looks good. When are you going to share info, or have available some of your ReVolt products ??? the HS Power PCB, SMT Controller PCB with extra mods, Driver PCB, Digital gas pedal ????

I still can not believe this group and all the accomplishments that it has made for Open Source EV’ers. Thanks again to Paul and everyone involved on this project !!!!

Keep up the good work !!!

-Mark
