Thumbs up

I just tried software 119 stock in my car.. holy C***!!!
It makes my 13.5 sound like my 4.5, only much more controllable
and the brakes are MUCH better too. Well done guys

The instruction reccommendations are pretty much bang on with the setup.
Heres what I ran:

Lrp X-11 13.5
FDR:6.75

4. DRRS 7
9. boost timing 40
10. turbo slope 18
12. turbo timing 24
13. start rpm 3000
14. turbo delay 0.2
15. timing acc 300

I will make a few tweaks, it needs a bit more low-mid range grunt.
I think I'll try this next and see how it goes:

4. DRRS 8-9
13. start rpm 2000

9+12 added together = 64deg... isnt esc limited to 60?

Yip. Just means it'll only use 20 deg turbo. I just left it at 24(default)

BUT ... start of blabbing ...
A silver can turns at about 15000rpm at max efficiency, what ever that is, but thereabouts. ???

So are the calculations correct?

The timing acc (#15 on the setup list) of 200rpm/°timing does not determine the rpm I think. It is only an acceleration figure, that the motor will increase the timing of 1°, at each incremental motor speed of 200rpm, but each timing increase will also increase the rpm of the motor, does it not??? and so the acceleration will not be linear.

We are ignoring friction and drag as well ...

If I am blabbing cr@p, please correct me ...

Hi, Chinaman. are you a real chinese? If that, I want to use chinese to talk with you, it's much easier.

In this example, RPM 13000 is the end RPM when total 55degree boost timing applied on the motor, but at that time the car's speed is only about 20KM/H.
The car will continue to accelerate with all boost timing on the motor. So just before the turbo open, we can not know the actual RPM of the motor, maybe 25000,maybe 30000, it's depended on the throttle control and full throttle delay time. But since turbo is designed to help the straight top speed, we can decide the open point by our experience , for example on a 60m straight, if I want to open the turbo at the half point, I can estimate the delay time the car needed to reach the 30m half point after full throttle.

Another thing we must care is to control the turbo not open at some other area on the track, which may cause difficult to control the car into a corner.
That's probably occured if you set the delay time a small value such as 0.1s.
So in such cases, what i will do is to keep the throttle not fully pressed than 0.1s.

In our test, we found too much boost timing will highly consume the battery power(voltage drop) and make your laptimes slower after several laps. You may feel it's fast at the beginning, but you lose your overall result. So we prefer to use TURBO timing which will not bring lots of current and hot and can be controlled by our hands. Applying the timing when the car has a higher speed is always better if you don't want your motor too hot.

sizheng,

i had some misconception of turbo timing before i read your post... thanc...
(silly loughing at myself)

somehow i need to know your estimation of length (m) of a car travelling before boost start rpm, let say 3000-6000rpm...

The acceleration may or may not be fairly linear; without the increasing boost effect the acceleration would drop off and be very non-linear. With the boost, it will be closer to linear than without it.

Drag and weight do not affect the calculations, although they will of course affect how quickly the car accelerates on track.

He knows the car setups very well so whatever he tells you guys take his advice as he knows the turbo function very well .As for me im a hardware engineer so any hardware issues please let me know as well as software.

Mr dong will be able to assist others as well when we are in bangkok for the titc in feb 2011 so please approach any of us for help .

4. DRRS 7

10. turbo slope 18
12. turbo timing 24
13. start rpm 3000
14. turbo delay 0.2
15. timing acc 300

I will make a few tweaks, it needs a bit more low-mid range grunt.
I think I'll try this next and see how it goes:

4. DRRS 8-9
13. start rpm 2000
Just loaded and set parameters for the new 119 software in a T3 with a SP21.5. Torque is up and ramp up to turbo kick in is smoooooth and when it reaches its peak, well thanks for belted touring tyres and good tyre glue!
Temps seem to be very stable with fans attached. Try out this weekend Saturday PM at our local track and results posted after with setups used.

Cheers

Agree
Before and after Boost and Turbo (supercharge)
we cant define rpm value,
and only during after start and simply just a calculation,

and at the edge of speed, the rpm is unknown, and also the timing,
as timing also increase on every defined rpm increment.

so we do need, the RPM Log in the firmware.

Sorry, i must say this again.

Irgo, you are so cute!

I can tell you when we test hobbywing 11.5T motors with FDR 5.7, the log shows the highest RPM about 43000. But the log is provided by another equipment. :-)
Don't ask me why and what, just want you know, we do log, but just for test and find the solution to improve.

Angelo,

See you in Bangkok. Thanks for your hard work to provide we drivers such a good communicating platform.

Can i ask you a simple question with the cap have you activated 100% reverse in use with full brakes as someone has advised on this forum ?If you have it's no the right way of doing it and i dont recommened it because when going to full brakes but as well as the reverse function your causing a massive spike in reverse polarity which in turn would cause the the cap to burn .please send me an email at [email protected] and we can work together on the issue to solve it .

regards Angelo
The issue seems to have been with the cap. I don't use the brakes, just rely on the drag brakes, and had the brakes set at 75% and 25% reverse. I think the issue may have been one of 2 things, either it some how spiked or the wire to the cap board became detatched.
I have fitted a replacement cap as advised by Angelo. The good thing is the esc is still working. I have set reverse to 0%, and set the brakes to Drag Brake, hopefully this has sorted it.
