OK, success, I used Zombies software and connected sk2 to tx as in gwhy!'s picture http://www.endless-sphere.com/forums/download/file.php?id=103777 and it works. Thanks a lot

OK, I have connected the yellow wire and the white wire. now, when I press apply on the xpd it says "Upload failed: invalid reply byte XX, XX is changing every time I do this.

reading your thread it seems I too am using the wrong pin for the yellow wire.

Thanks for answering so fast, I don't think I have the new version of the controller, its actually an old one: I will try your suggestion when I am back home. here are some pics:

Hi, I have an ecrazyman 12 FET controller. the board is EB312-AS-2. I tried programming it with a LYEN programmer and XPD, but it just sits at "waiting for controller ready". The chip is GPM8F3108A-QL011. Did anyone program those?

It could be one of the following: 1. Battery voltage is dropping when you accelerate - you are using 12S? what is the cutoff V of your controller? if its a 48V controller you may have a problem here... 2. Try playing with the black connector (7 pin) from the motor to the controller - if the...

Are you using the original cyclone throttle? if so, what do the leds show when the controller cuts?

Do you have a sensorless controller? this can give you a lot of extra knowledge on the problem. I had the same problem - my controller is a e-citypower sensored + sensorless controller, I disconnected the hall sensors and found out (as other members mentioned) it was going the wrong way...

Thanks for the warning Flathill, I may be naive, I still believe Wang is OK, but I Don't really know. I guess one can call the factory and authenticate Wang.... Anyway I guess its good to be a little paranoid :D

I mean the hub diameter between spoke holes ("d" in the picture)

I don't have its specs, just what's written on it: 24V200 and what I was told when I bought it. It weights 3Kg, I guess these motors are rated just to pass regulations. The motor spoke holes diameter is 130mm is that your size?

The power @ 50km/h is arround 1000W (I am not pedaling), I weight 87Kg and I am taking my son with me in the mornings - he weights about 15Kg, it does not affect much, but I am not going 50 with him on. I bought the motor from a local importer in Israel, so I can'y say which brand it is - see...

I am going 50 km/h on a 200W rear geared hub, 12S Lipo, folding bike with rear suspension, the motor does'nt get hot, only slightlly worm, I tried putting the controller inside the battery bag, but it got really hot after a hard ride (a 450W 9 FET controller from bmsbattery, 22A limited), so I...

I have to disagree, The reason I posted this post is because I experienced better performance (less voltage sag) with these cells than with other LiFePo4 cells (Headway, PSI). I have just finished discharging @ 20A (2C) and here are the numbers: Ah out Total V 0Ah...

Test results @~0.75C made a 4S pack and discharged till lowest cell had 2.5V - exactlly 10Ah I got 125.2Wh and 10.000Ah, this means the avg voltage @~7.5A is 12.52V (3.13V per cell). pictures attached:
