Program card with progressive punch control

A current limiter would be nice for wet/very low grip tracks like the Tekin system has. Something that doesn't mess with the throttle like punch control does.

Does the Tekin actually limit current, or is it really like punch control, just with a different name? To limit current spikes, I would think you'd have to slow down the throttle rate of change to give the motor rpm time to "catch up" to the applied voltage (basically integration), and this is what punch control is.

I don't own a Teken system myself, but a mate does and he uses the current limiter when he's running on wet tracks. I should figure it out some time.

I'm now running a Castle 2200kv combo in my 8ight and I have too much power when acceleration on lose dirt.
We're racing under a brige and it never rains there, so the ground is very lose.
Would it be better to set my timing at 0 and increase a teeth on my pinion to loose some torque? Cause there's just way too much wheelspin.
Punch control is a nice feature, but I don't like when there are jumps. It's harder to control the car over jumps/in the air with punch control :(

EDIT: This is a quote that I found on Rctech, so yes, it seems like a real current limiter. I think that would be a very nice feature on the Mamba Monsters!

I had the same issue with punch control. Worked great for controlling wheel spin but took away all the ability to control the car in the air. I could never bring the front end back up if I was too far nose down! I had to move it back to zero.

With that said, Tekin does have a current limiter on their rx8 that works very well especially if you have overly punch lipos. For instance, my car works well with a pair of 5s 3300 rated at 30c. However, I have a 5s 4000 rated at 40c that I use for mains. The 40c pack is significantly more punchy than my 30c packs and screws up my timing on the track. The Tekin current limiter will make the 40c pack feel exactly like my 30c packs

MMM XL suggestion - I'd like a mode or a way to reset the logging memory when the ESC is armed. Perhaps an ad-hoc mode i.e. hold reverse on plug-in.

And / Or perhaps there could be an ESC mode when the ESC memory is cleared every time the ESC is armed.

I'm never going to have my PC with me at the start and end of every run.

This is something that has been discussed but probably won't be included with the initial release, but could be easily be added with a firmware update. It is already a feature on the ICE controllers, so the software is capable of doing it, we would just need to figure out what throttle sequence would clear the data.

Turning it on at full reverse is one option, but if someone has their throttle signal reversed it could get confusing if they're doing throttle calibration; the chiming the controller makes when it's clearing the data could be confused with the full throttle calibration chimes. But I think this would be a very rare occurrence and easily troubleshot.

This may be something that Richard has already added, I'll double check at the tech support/engineering meeting on Thursday. Thanks!

When we getting logging in the other controllers, i.e. MMP or MM? Or is that even possible without hardware updates?

BrianG · 12.07.2010, 02:35 PM

Not possible with the current hardware. You need the HE sensor, some memory, and extra code to utilize both.

Just an idea for "non Castle cans"

Would it be possible to allow more than 20 degree of timing on Sensorless Motors ?

like up to 25 degrees ?

Sorry, no... Sensorless is limited to about 20 degrees of maximum timing. Nothing we can do about that.

thx

was just an idea

Patrick the switch on the MMM kills the power to the microprocessor or only puts it on stand by ??

It takes down all the power supplies (including the microprocessor power supply.)

However, there are still some parts that draw a small amount of power when the switch is off -- so you can't just turn it off and leave it connected for days. It will eventually flatten your batteries.

I am running the Conversion in my Baja 5sc and I can't seem to keep the truck under control. I tried the punch control but that just feel's to me like throttle expo. It works fine but it seems like as soon as you hit half throttle the truck takes off into full wheel spin. I have had the rear tires come off the rims twice now. I am going to try torque limit next but I am not sure what setting to try first. Any suggestions would be great.

You will like the torque limiter -- it does exactly that -- limits torque.

Try starting at "4.0" and if too much torque, dial it down. If not enough torque, dial it up.
