Esc turbo

[Welshy40]

Guys,

I have never since the day brushless came out used the turbo function but am perplexed on this, so what exactly does the turbo function and timing function do?

Am i right in thinking with turbo it just gets to top end quicker than the standard settings or does this make full speed much more?

was speaking to someone knowledgable the other day, and he said,
use timing if you want the motor to be faster overall, but if you want it the same speed on the infield, and need more on the straight, use turbo which will kick in after a preset (by you) amount of time or revs.

at a guess, turbo increases the timing - making it faster - when the throttle is at max for a certain amount of time or revs.

More motor timing will give you a quicker top end,less torque bottom end and more heat in the motor,

Turbo will give you that bottom end back if you need it,if your motor gets to hot,decrease the timing on the motor and add some boost and turn the turbo down a bit........................I think 😄

Interesting, so easier to do via the esc rather than adjusting the motor end bell.

You can usually set timing in the esc in the same way as on the end bell and the timing will stay the same throughout the rev range.

You can then also set turbo or boost (I can never remember which is which) so that for a particular number of revs that are increased the timing is also advanced so the faster the motor spins the more timing you get allowing the motor to go even faster.

Then you can set the other one of turbo or boost so that you get a further increase in timing after a set time delay at full throttle.

Boost Timing and Turbo Timing both add timing advance, they just apply it in a different way.

The way I adjust it is if I want more revs (speed) everywhere, I increase the boost timing. So, first of all I set this and get it right for the infield, as that's where I want the throttle to feel nice and controllable.

Then, if I want more speed on the straight(s) I add turbo timing. On my esc (Absima CTS10) it only gets introduced after a set amount of time holding full throttle . The great thing with this is that it adds revs where you want the speed, but doesn't make the car way to aggressive on the more intricate parts of the track.

On slippy tracks its best to run little or no boost and then add turbo with a long delay if you need more speed on the straight.

On high grip I normally run both turbo and boost and have turbo kick in after a very short amount of time on full throttle.

Warning - don't turn up both to full as you are likely to damage your motor and/or esc. Do things gradually and keep an eye on temperature.

Hope this helps.

Boost timing is applied across the whole of the throttle range,
Turbo timing is applied at full throttle or a set rpm (dependent how you have set it in the ESC)

Although boost timing is applied across the whole of the throttle movement it can be set to come in aggressively or smoothly.
in Simple terms for an aggressive setting the start rpm and end rpm are close together this adds the timing in quicker, it can be fined tuned by the slope (degrees or secs of timing added higher degrees or lower secs will add timing quicker)
This type of setting will also increase the heat in the motor quicker.
for a smoother introduction of the timing have a greater distance between start and finish rpm. to fine tune do the opposite of above.

Start rpm depends on car ,track ,gearing.

If you start running boost & turbo lower your gear ratio (higher number i.e. go from 4.5 to 6.6 ratio)
ALWAYS Temp your motor after 2, 4 mins to ensure you do not burn out the motor see the instructions that came with your motor for the max temp they advise!


Best explanation of all the settings and how they work is probably in the Hobywing manual
