when is speed passion LCD Professional
to allow Torque Limit Custom Value, DMTS 2.0, etc.
even Graphics adjustment software allowed us to have multi curved.

this our mandate.

Just after a bit of comfidence really with the different firmware upgrades for the speedo just ordered my LCD PROGRAMMER and after reading some positive things people have said that there is quite an improvment to be had from the software that comes on the speedo from the factory whats peoples poinions on this from testing? and has anyone found one thats really good with 10.5 brushless? I know there are some on this thread but its so long now id need to hire someone to read through it for me ! lol

Cheers guys....SP all the way!

When I first got an SP ESC (GT2.0 LPF), and Ultrasportsman 13.5, I also ordered an SP sensor cable -- everything worked great...

When I bought the second GT2.0 LPF, I used it with a Novak motor -- everything worked great...

However, when I did some motor swapping and changed from the Ultrasportsman 13.5 to a v3 13.5, I needed another sensor cable, and all the hobby shop had were LRP cables. I figured "No Problem" -- they are "compatible", right?

The original LPF worked fine at first, then during the second heat race, the car started to run rough and lost speed..???? After the race, I found that the sensor cable had worked loose at the ESC... Plugged it back in - made SURE it was fully seated, ran fine in the third heat... Then in the main, same thing -- cogging at low speed, lost top end -- sensor cable loose again...

At home, I realized that the LRP cable plug seems to be a hair smaller, and doesn't "lock into the ESC"... ????? (even fully seated, it pulls out easily with just a small tug on the cable..)

OH -- PS: at the track I tried to change to a Novak cable, but no-go -- it would NOT fully seat in the ESC.. As noted earlier, I've run Novak motors/cables with the other LPF, so I know it SHOULD work, but...?

I now suspect that "compatible" really isn't, and that the quality control on these little cables isn't what I thought it was...?

Any advice on sensor cables? Are the SpeedPassion cables that much better? (I NEVER had a problem with this ESC using the SP cable with the previous motor...)

Thanks in advance for any help...

WRONG! -- In the first heat, the motor/ESC again reverted to sensorless mode, cogging at low speeds, and losing 10-15% of top end speed... I changed to the SP sensor cable for the second heat -- motor/ESC ran great, so I figured "problem solved"... WRONG! In the third heat, the motor/ESC again reverted to sensorless operation, cogging, etc... I gave up and installed the old Ultrasportsman 13.5R for the A-main (with SP Sensor cable) -- ran perfect...

I now assume the problem is with the motor -- most likely a bad sensor assembly, as the motor runs fine otherwise...

QUESTION: What is the part number for the v3 sensor assembly? Where can I order one...?

You may be able to shim (remove shim/s and move to the pinnion end of rotor) the rotor closer to the sensor board.

We were dynoing motors and found on the version 2 this would stop cogging as the motor warmed up( also increased power by 5 watts)

From the video of how to disassemble the v3's, it looks like the sensor is held in place by being sandwiched between two soft vinyl pads, which might (?) allow for movement of the sensor unit...? On the other hand, from the external view, this motor has zero endplay of the rotor in the can, so I don't know how much there is to "shim" unless I can move a shim from one end to the other, but the video doesn't make it clear how the rotor is shimmed, so...?

From what I can see SP came out with a new ESC for a reason. I know that the 2.0 is a great speedo. I ran one myself for quite a while and really liked it. Once I figured out that all the settings have a certain purpose. I am pretty sure the timing settings on the esc work best for specific motors. I just dont understand why some are so demanding from a company..(not to make it sound like they are not listening to us) and should be listening to everything you say at all . They have there own R&D with people who know what they are talking about because unlike us are actually on top of there ISh

I know they have great customer support but I kinda feel sorry for them at times when I read this thread

Remove a shim at a time and see how the gap closes up,put that shim at the other end so as to not increase the total end play and give it a try.

Cannot wait to test the 2.1 stock software
