Hi Randy,
thanks again
Why does it matter if a car is direct drive or have a reduction gearbox? I always thought TC's have higher end RPM because their motor turn more due to having 2S Lipo. With other words, I would use the 2k - 13k range with a 1:10 pan car if it is run with a 2S LiPo. Am I wrong?

Does running 1s or 2s lipo have anything to do with setting the RPM range? I gues it will? For instance i am driving a pancar with 10.5t on 2s on a track with a 330 feet straight. Would i still be in those rough guidelines of 1000 and 7000? Or would i have to open up a bigger window of 1500 and 10,000 for instance(just randomly chosen) so i can have a higher rollout for more speed down the straight without heating up the motor too much too soon?

Just curious.

I hope i will break the 58mph barier with this software and the 10.5t duo2 next summer season...too fast..don't think so

oze just beat me to the same question

I would set the RPM range bigger so you can gear like you did before.
I think it will go a lot faster after I field the power.
RPM range I have now on my car is ~ 3000 till ~ 1700 RPM.

Tonight to the club for 1:18. Maybe something to for in my M18

emiel,

are you sure about the 3.00 and 1.700? Wouldn't that have to be 3.000 and 17.000 rpm?

Yes forgot a 0
Sorry.


I listen everyday to the sound of the motor. I just give a bit of throttle to hear the motor and the speed. I stop in time so I don't blow up my tires

Cpt.
Without giving away the farm: Because we can now. With Vegas 1.0 and prior software that was always a reccomendation. There were too many motors that had various degrees of timing settings. Now that we have this much control the motor timing is less of an issue and we can push past the 30 mark. Yes the rpm schedule is VERY helpful and a big reason why we can do this. Before you were limited on when the timing boost actually occured. Now you can choose to fit YOUR needs.


1s vs. 2s will have "theoretically" double the rpm set points because it's twice the voltage and twice the rpm's.

TC's or gearbox cars have a reduction to them where as pan cars or direct drive do not. They rollout differently on the track. These are not "set in stone" and can very with drivers, tracks, layous. But it should help everyone understand. Setting your TC with say 1,000 start and 5,000 end will work but that will more than likely cause your timing boost to always be ON. You will likely never roll down to those rpm's on the track once the car is moving therefore defeating the purpose of ramping timing.

Had a chance to try out the new 203 update last night, it is FAST needless to say. Without getting flamed or being told to read through the last 50 posts, can someone give some guidelines for achieving the best LOW END TORQUE/ACCELERATION?

Our track is tiny, maybe 10 turns and 8 second lap times in 21.5 rubber class TC. If this has been answered before maybe someone could copy and paste a link to the specific post also.

Many thanks!!

What???

Are you saying that the RPM range is the Timing Ramping Range, and after maximum RPM's are reached, 5000 in this example, that the timing stays consistent from anything above 5000 RPM's?

In my head I was thinking the Timing Boost stopped adding any timing after the maximum RPM was reached. So what this software has really allowed is to get the car moving first before adding timing, which is why we are seeing reduced temps, and then maintain a linear timing from the Maximum RPM+ the ability to ramp in the Turbo Timing at an extremely fast rate.

Ok, I love the 203 version, but I just would like a little more explanation regarding the startnig rpm and end rpm.. I'm using the settings of a friend, but I would like to know what they do

How is it that it works exactly?

Any help please

At the track again today doing more testing. Got a 13.5 DUO1 in the middle hole in a rubber sedan, and with 50 boost and an RPM range from about 4500-10000, the motor seems too want to be geared around a 5.9 before it really starts to come to life. I tried a 7.0 and it was slower than a 17.5. This DUO was brand new.

If this ESC has the ability to log any data, I'd love to see a timeline showing RPM vs time, and then do an overlay of timing on top of it to see what's really going on when and where throughout the run.

there is a large document on the new software that expains everything quite nice.. some pages back...



but the short answer is, the start RPM is where the ESC starts timing the motor with what ever your Boost is set too in intervals, and the end RPM is where is stops adding more. turbo is solely full trigger time based, and is only usefull if you have a realy long strait..

would be nice if the moderators would sticky important info like base setups and the documents so we won't have a zillion questions being asked. Thought it would be a good idea because I see the same questions being asked page after page, but the answer is buried somewhere in the past.

Yup, that's how it would work...

When I was using DUO1 13.5 , my car was geared 6.25 with vegas 200 software. It was fast. Play with your start rpm and maybe your throttle profile? ~7.0 is my DUO2 sweets spot at the moment .

I would try 2500 with throttle profile 4 or 5.

Timing Boost: Acceleration

The ideal start/end rpm for boost will depend on the platform/chassis being used along with track size and motor wind. The size of the range will also affect how the car pulls. A narrow rpm range will effectively produce a faster rate of boost vs. a wide range will have a slower rate of boost:

1000rpm start / 6000 end with 50 timing boost will provide 10 degrees of boost per 1000 rpm vs.
1000rpm start / 11000 end with 50 timing boost will provide 5 degrees of boost per 1000 rpm.

Spec Motors:

So far pan cars are using between 1,000 and 7,000 on most tracks. This is due to not having a gearbox and being direct drive.

TC’s are showing a useable range of 2,000 to 13,000 on most tracks. This is due to having a reduction gear box.

Turbo Timing: Top speed

Turbo Delay: This is the time that must expire at wide open throttle to engage turbo. This is NOT dependant on RPM’s in any way. Ideally this should be NO lower than .2 and in all likelyhood will be set at .4 or more. Tracks that have straights less than 80ft will likely NOT need turbo.

Turbo Ramp Rate: This is the literal ramp rate of whatever your turbo timing is set. So:

A turbo setting of 20 will give you the following reaction:
1.0 Ramp rate = 20 degrees in 1 second applied
2.0 Ramp rate = 20 degrees in .5 seconds applied
3.0 Ramp rate = 20 degrees in .30 seconds applied

So if you run timing it will just change the total applied, not the speed at which it’s applied.
This one.
