SCP-01 on ninco digital

Well the ninco powerbase only issues 11 pwm steps so that's its limit right there..The std throttle only uses 9 of those steps in the pro mode..So if you think its worth it..go ahead and knock yourself out..
If the thing even works at all then I will be happy for the people who buy it..
Im sure it wont be able to do anything about the brick wall 100% ninco brakes..If you want better throttle response for N digital..Fit a 50 cent 3.3 volt zener diode in the + wire between the chip and the motor..then fit a $1.50 mini multi turn 5k trim pot in place of the first resistor on the throttle board and tune it so it utilizes the non used throttle segment that is the next one after brakes..better yet replace all the resistors on the board as per Razaman's guide so as to achieve an even better result..
In short..I dont think there is much that can be done by a fancy expensive throttle..Ninco doesnt have enough PWM steps to achieve a linear feeling throttle curve and the brakes are set in stone and can only be altered by altering the setup in the car..ie magnets and diodes..

This may be very close to the diode mod which, I think, basically eliminates the brake, especially with strong magnet racing.

The diode mod doesnt totaly eliminate braking..it is still there I said in another thread that i was using a 3.7volt zener...I was incorrect it is actually a 3.3... Different feel (more brakes) can be had by using a 3 volt and more again by using a 2.7 volt.
My problem with those was that the only ones I could find,werent able to cope with the bigger NSR motors..The diodes would heat up and fail.
Finding that the 3.3 I use is bulletproof and works well with the NSR's which have heavy braking effect.

Have had a look back at my notes from when I tested the Digital Module last April. In the Ninco tests in Pro Mode I was able to select all the steps including the "hidden" ones.

This increases the number of available steps from 10 to 14, the top step is however still limited to 7/8 PWM the same as the standard controller, as this is a fault that cannot be fixed by the controller.

I did however find that becuse of the small number of steps available there are a number of setting of the Min & Max pots that give very little control. Also as is known, variable brakes do not function in Ninco mode.

To be honest trying to have variable profiles with only 14 steps is very difficult and of limited value. The SCP-1 with digital module works well with Scalextric which has 64 steps, throttle profiling, Power Trim and all the other controls work in the same way as they do in Analogue. With all the other digital systems which only support 16 or less steps, the other controls are of much less value, and in some cases useless.

Note. These comments are made on what I think was a final pre-production prototype, however it is possible that changes have been made since then.

I did not buy the SCP-01 and won't: I made tries by changing the resistors in a Ninco original throttle (following 'Matraman' advice) and bought an expensive modified Parma, also with a potentiometer and modified resistor values.

Honestly, I felt that the changes using these different controllers were more psychological than factual! Sure it's a little bit better but the improvements do not justify the time or money I spent.

Then I realized, as Rich wrote, that the car's chip reads from the track just 10 or 14 different values (steps), and without any regard for the motor's type (or the controller's cost!): buying a 'better' controller can't change the number of available steps in a significant way since it's the Ninco protocol on the tracks that enforces the number of steps.

So I guess it's better to spare the money for something else... (I plan to test Scorpius: 256 steps should be a different story!)
