Default LRP Sphere Comp Timing

Some of us at the track today were discussing the differences between hardware and software timing of brushless motors. We were wondering if anyone has any idea how much software timing was being advanced in the different settings on the Mode 2 (ADPC) function on the LRP Sphere Competition?

There are 8 possible settings, but it is unclear how much the motor is being advanced or retarded in each of the settings? Has anyone done some research on this topic that might have an idea. I would call LRP, but my German sucks!


It is clear that timing is being advanced based on the LRP Note that says: Do not advance the mechanical timing on settings 3-6...blah blah blah. I am just not sure how much!

Hey artwork,


Im not sure if Im right but I think the LRPs have what they call a automatic timing. I think its 30* but I could be wrong. I would call up Assocaited and ask about it.

I know its not much info but I hope this helps.

I personally would like to know how software timing differs from hardware timing because I was having this debate with a friend the other day.

We really need an LRP specific thread on here like other companies have with a rep to answer all our questions. "burito" works for LRP, maybe we should all start bugging him? hehe :P

The "timing question" for our speedos is not something which we are willing to explain at this stage and therefore I can not answer the question. Sorry!
But as far as I know our system is still superior then the others...

As for an "Ask LRP" thread, I do unfortunately have only very limited time on these forums and I'm worried I'd be too slow with my replies (especially when I'm away at races) which could result in frustrated customers.

I do understand that this is something that might be proprietary to LRP, but in the quest to find the right setting on my LRP in conjunction with the motors I am running this type of information could be very helpful. Through some research I have found someone claiming that on setting 8 there is 20deg of timing, but I am just not sure that is true.

Thanks for responding!

ya know i'm going to take a stab at this and guess whats going on with "timing" (still not sure thats the right word to use)

here's facts I have at hand and can remember..

LRP motors are labelled with a range from 0 to 8, increments of 1
LRP motors are set by default at a "timing" of 2 on the motor can according to the label
LRP 3.5T manual says not to change the default timing from 2 for that motor (this bit i had always wondered why, but never changed it)
LRP "stock spec" motors appear to be locked at 2 degrees timing on the motor itself

here's what i'm concluding..

the default of 2 on the motor timing could correspond with the ESC base timing figure
it is possible that the base timing figure could be 22, which with the motors base timing of 2 would give 24 degrees of "timing" (a figure we all know and love!)
the 3.5T motor may draw too much current when set at a timing higher than this theoretical 24 degree timing, other motors not so much.
and lastly, the range of timing available with an LRP motor and LRP ESC could be 22+0 to 22+8 or 22-30 degrees.

what a theory!

-Mark

So for LRP Speedo's we're not supposed to adjust the timing mechanically? What is the setting we should use on or motors? 0* or what?

I wouldn't say that. It depends on what works best for you. I invariably run program 3 on my LRP TC speedo and use the timing on the motor to fine tune. But then that is me running mod. For stock and possibly super stock I would probably use program 8.

As to the programs on the LRP speedo's, I can understand Reto not willing to divulge details. I am quite certain the difference between the programs is not solely timing. I can imagine variable timing settings at different throttle levels, different frequencies (also at different throttle levels) and several other parameters that may differ from program to program. Meaning with the timing on the motor you solely change that while changing program changes more than just the timing.

I took my LRP 13.5 apart the other day and can't get the 'end bell' part or the internal piece to move. (Screws are all removed.) How do I remove the interal piece and how does one go about setting the timing?

Would that LRP 13.5 be a stock spec with the orange timing ring?
If so, timing appears to be locked at 2 degrees on the motor without the ability to alter them.

I have an original "Sphere Brushed/Brushless" ESC, and there are only 3 throttle profiles.. Sportsman, Low Traction, and Modified..

What are their equivalents to the newer Spheres with 8 modes? I have a 13.5 and 17.5.
