that is good to know. I always thought I was leave something on the track with not being able to get close to the max no load rpm. i just figure there is a lot more time in the turns then on the straight so i figure I did not need to be the fastest down the straight.

Why BL-DL and not BL-FW?
May you use it in the races?
Set your Turbo on 0 and higher your Boost. st it to 45 to start with and find a good infield speed.
You can raise it as the motor stays cool.
As you than come top speed to short you can ad some motor timing.
But for a good setup give some more information about the motor.
Hi,

RS Pro + 17.5 Duo 2 in 2S LiPo WGT CRC GenX 10 (as previous post title say :-) )
BL-DL is for practice.
Thank you.

Jim (and Yang),

How about an All Tekin Test Weekend? Or, a seminar for devotees. I'm willing to travel for that.

Just a thought...

Ok didn't read the title sorry.

Than you have a very low Boost for a 17,5T.
This can cause that you don't really feel the Turbo.

Set you Boost to 50
You get more top speed and you don't need the Turbo.
As you still have not enough top speed, than ad some motor timing.
You can always ad some Turbo. This will give you extra top speed.
The more Boost you set the more you feel the Turbo.

Thank you Mikky32. It is just that my previous configuration was with SP V3 17.5 motor and that system was a little bit quicker, cooler and felt better than I have now with Duo 2. Ok. I will check what you have suggested and will try to find setup which works with Duo 2... Last (but not nice) option is to change motor...

The DUO 2 is a fast motor.
For more speed as the Boost alone is not enough, try some motor timing.
Watch the motor temp.

Thank you.
i drove wgt with 2s lipo and 13.5t duo 2 on a small indoor track with 20-30 meter straight and had the following setups:
Boost 50
end rpm 9000
start rpm ~1500-1600
no turbo
rollout ~ 33mm
dragbrake 0
nw 12
bs 100 (turned to 40 on the radio)

other one i used last time was:
boost 54
end rpm 10.500
start rpm ~1700 or something
rollout ~33mm
dragbrake 0
nw 12

great speed out of corners and motor temp was only 45-50 degrees C after 7 minute race.

The first setup had a motor temp of 35-40 after 10 minutes but had more acceleration except on just over half of the straight it topped off. The second had a little more top end it seems. No motor fading whatsoever. Had standard motor timing.

For a 17.5t you should get a slight higher rollout then 33mm. Just look at the speed and motortemp and gear accordingly.

Our default rpms are stupid The high rpm value needs to be 8k to 12k at least to be really getting any sliding action on the boost. Even 8k may barely reduce the boost timing at all even at the slowest part of the corner.

Thank you for the insight, it gives me a much better idea now of how the boost works

I will try using a value of 6000 start rpm and see if it suits a small track...

to give you an idea. without turbo or timing, my baseline was a low of 2968 and a high of 12,875 on the back straight and on the infield 8,042

I am not sure how much value these numbers are because imho tekin setups now need to take into account too many variable to make a setup work everywhere. I can tell you that this setup really is setup for our track the day I ran it. this was after 3 round of looking at sentry data and adjusting start rpm, end rpm, turbo delay and gear ratio. this setup was basically optimized as much as I could for the track. I was able to put a full lap on my best times. I rarely find any change that I can do that with.

for that one setting in hotwire that deals with concave throttle profile or whatever its called, what is a value to use to give it a linear feel? I see it goes from 1 to CST, but not sure what that means in relation to the setting. Does going higher mean more curve? Lower more linear? etc.

Also heard you guys are working on a more simple interface that isn't as busy as the current one and hopefully with bigger font, any timeframe on this?

So what does going higher than 3 mean, and what does going lower than 3 mean? Also, what does CST mean?

Higher is till 5.
It gets more aggressive.

The CST is custom settings but they are not there so on this moment 5 is the max.
1 the mildest reaction.

With what turn motor?

I find this hard to believe simply from the fact that during my testing, I noticed a significant delay in the boost coming in when I switched from a 2,500 RPM start to a 4,000 RPM start. This tells me I am going below 4,000 RPM on some of our corners.

Our track is by no means small, even in our 180 hairpins you can carry some speed because it's a large outdoor asphalt track.
