soon...!? hope not too long...

cobra...
is that true more boost timing will decrease low-end torque...? meaning that if at very short technical track, we should reduce boost timing to gain torque at low-end, is that the way...?
i need to know where is your preference at boost start rpm, half of straight length or more...?
thanc for reply...

To be honest with you i do drive and do alot of testing but im not a good driver by far lol.But from what i do i get a better understanding how the whole concept works .

Now yes you will decrease low end torque with high boost settings but that all depends on alot of things gearing is one ,track length is another ,turbo delay they all come into play .

Boost start rpm and delay id start at 1/2 to 3/4 somewhere in between on back straight depending on the length of the track this will give you some needed to time to slow down at the end and regain the low end torque coming in and out of the corner .

Ive seen alot of racers leave the delay to late and the turbo cutting in towards the end of the straight and they cannot handle the power coming into the corner then they lack lwo end torque to boost the turbo again .Think about it like a full scale car usually your max boost is mid to 3/4 track and then you need to start slowing down before hitting the corner its the same in touring.

Believe me think basics and think in the sense of full scale and you will understand the turbo settings in these esc's better as the basics are the same no matter r/c or full scale ,more boost more heat on full scale same as r/c more boost more heat so the concept is 100% the same very basic just some need time to understand it .

anything else you need please email me teamcobraracing@gmail.com or ae@hobbywing .com

regards Angelo

Sorry to jump in on this point, esp after Angelo already answered.

Boost timing will only decrease your torque if you bring the timing in at to low of an rpm, or bring it in to fast. If you feel you dont have enough low end rip, then try raising your start RPM a notch and see if the car feels better to you. By keeping the timing lower, it will allow the motor to make the most amount of torque when exiting the corner. If the car feels flat during the corner exit, and then a huge surge of power (as Angelo explains) you can also try lowering your start RPM, but decrease the rate that the tming comes in (so increase #15). I find it flatens the throttle out abit, making the car more controllable in the infield.

Thanks shawn for your input its good to see guys likes yourself helping out and making my job a little easier .Thank you very much and it also good to see that there is no arguments in this thread but excellent tech work for all to learn .

I will reveal one part of the software and that is the brake force goes from 4 options to 8 options in this new software so more brakes for all .

thats all i can say for now but many more to come

Default here's a question

I have a question, Turbo effectively ramps the car up at high speed, so coming off turbo will has that kind of aggressive power drop.

Now, does advancing the speedo timing have the same effect, or is the coming off power characteristic smooth and linear?

I ask this with a view to switching off the turbo and advancing the timing

I have always thought it was smooth. It may depend on how much drag brake you use (and I use a lot for off road)

Taking away turbo and using more boost timing and lower FDR will make it alot smoother.

Even a low turbo set up will help, you dont have to throw it away completely...

I race 17.5 touring and only really notice it on sweepers... But if i mess around and lower the FDR and run less turbo (usually run max boost) and adjust the punch accordingly (higher value for lower FDR) its fine...

Hope this helps.

When the new software is available it actually really linear on the turbo getting on the turbo and getting off .so please be patient and you will see some major changes .

Turbos are always aggressive more than just normal timing .

Cheers m8

I am gonna be patient, but in the meantime I will try and reduce the turbo

I must say that I am always happy to give up a bit of top end oomph for more useable, modulated power
