I have read this in another thread, I realise I should have replied here.
Below is the answer I gave in the other thread:
That explanation doesn't clarify two points.
1. Are timing boost and Turbo applied as set timing values or ramped up progressively?
2. If timing does not (or should not) exceeed 30deg, how can Turbo apply more timing if your overall timing is already 30?
One other question here that seems to be indirectly clarified but not clearly stated is whether or not there is another parameter monitored by the speedo apart from RPM. From the explanation above it seems there isn't.

Turbo does ramp up over the course of say a second or so.
If the say you had 15 motor timing, 15 of timing boost vs. 20 on the motor and 10 on timing boost the answer is that they're the same but different.
They're the same once the car is under speed, but are different from the start to first few feet of car travel. This alone will create the need for slightly different gearing between the two.
Most onroad guys prefer less motor timing and more timing boost hence the 0 motor timing 30 timing boost setups.
Where as the offroad guys such as myself prefer more motor timing over timing boost. I usually run anywhere from 15-20 on the motor and make up the difference with timing boost depending on traction condtions.

Timing boost is not a full "dump" but it's is VERY agressive in it's ramp rate.

This is very helpful for old dogs like me.
I guess then this means the total timing on the motor (fixed, boost and turbo) can go over 30?
I do indeed find that 0 motor timing plus high boost and turbo adjusted to track/gearing worked best for me (racing on road carpet 21.5).
The Tekin system is indeed very good, and it is obvious at the track. Using the motor/ESC combo in the 21.5 class we are approaching 17.5 (stock) lapcounts and lap times. The 21.5 class record laptime is under assault already. I have managed to come within .2 of a second on several occasions and lately I am within range constantly over several laps in a row in the same race, so it can fall at any time now. If my skill was up to it, I am sure it would be gone already. For the moment though, my gear is way better than I am.
Just hope the system is going to be as long life as my brushed systems which is no small ask, but crucial to justify the expense.

Is it possible to have the boost/turbo reduce and then ramp back up with a increase, then decrease in the load? I am using a couple of RS pro's in oval and it is full throttle for 5 min. turbo is of no use since its time based. Would like it to be load based. ie if the amps go up after turbo is engaged, then reset the time. That way when the motor does slow in the corners the timing/boost would reduce slightly then pick back up as the rpms pick up for the straight.

Slot, I understand what you're getting at. I can't and won't comment on what and how we're making the next bit of changes, sorry. We've already educated the public and the competition enough at this point. I'm sure you'll understand.

Because both parameters have the term "boost" after them I prefer to use turbo and timing to clarify. He shared that turbo obviously has a gradual ramping increase after the delay has been reached, and timing has a ramp as well, only it is a very aggressive increase. Clear as mud?

I will be wiring my 12th and I was wondering how close can the sensor wire be to the motor wires?
Thanks for you time

Does the amount of turbo affect the top speed or just how fast it gets to top speed? Also is there a limit to the amount of timing and turbo? I know motor and speedo timing should be kept around 30, but is there a relationship between timing and turbo as well? Thanks.

Wasnt expecting a this is how we are going to do it. Am just hoping you are doing something for the oval guys as I hear rumors of new controllers that are using variable timing and are faster than the Tekins. Just looking forward to the next update for my RS Pro's. The ability to update to new software as it becomes available was my number one choice in picking tekin controllers for my cars (4). thanks for the great products.

have not had a chance play with a motor with negative timing!
are we expecting the most torque, and least rpm with the negative timing? and possibly more torque than a motor with 0 timing?
hence the reason for a relatively high timing/turbo boost combination?
does that mean the overall timing is -15, +20, +20 = 25?

regarding the motor timing on this setup up, it says -15, meaning timing on the negative 15?
