Depends on your radio system. As explained a dozen or more times throughout this thread by Randy and crew, running your NW too low, on some systems (like my 3pk) can cause some issues. Running it higher will NOT give you a non linear throttle response.

running it higher will shorten the throw of the trigger which in turn does take away from "linear"

i ran my NW at 15 and had issues with it feeling like it had drag brake even with it set to zero and my brakes didnt feel right when applied, after jumping it up to 30 all is better and throttle is as smooth as can be.

OK, coming at this from a different angle. A couple of weeks back I returned to my local track changed the FDR accordingly and went racing. I experienced a momentary delay on applying the throttle, then the boost came in hard. The car was fine everywhere apart from exiting slow corners. On the start line everyone was leaving me standing. Too much timing came the cry. No its not I have used this setup a million times here. I swapped out the engine to another make and put in the settings I had recorded for that engine - same problem. Hmn; I resynched the transmitter; same problem. Frustrated to the max, the following night I sat at the bench and tried to work out what an earth was going on.

In the end I reflashed the ESC with factory default settings and then applied my settings. Problem solved!!!

I can only assume that a variable in the firmware had got corrupted somehow and loading the factory settings cleared it. Of course the guys at Tekin will know whether I am talking garbage but I and others checked the settings in the Hotwire interface a hundred times ie it wasn't me.

Maybe worth a try.

I've set my NW all over the place between 56 and 5 and didn't really notice a difference(DX3R). Having said that, I did have a problem two summers ago when I had teh NW down low, 9 I think it was, and every time I hit the brakes the car would shut down for a couple seconds and then restart. I would have steering, just no throttle control. I went back to a higher NW and the problem went away. Never did figure that out, but I have just kept the NW at the factory setting from that point on.

Not a bad idea yellowshark, definitly worth giving a try anyway. i wonder though if it is some sort of corupt file why it only effected me and not the other two guys I set up that day? I watched them both and they had mad rip out of the corners. Granted they are driving different cars than me and with different gearing, but I would think as bad as the problem is for me I would see it in their cars also.

thinking about running T/A Class and i dont have a brushed esc. and i have no idea how to hook up my Tekin RS to a Can motor? any1 help me

Weird

I was using a DX3r before. NW was set to 15 before, and I was experiencing your issues. What fixed it was the NW. I had it on 15, and set it between 2-5. It fixed the lag/sluggishness.

I'm using KO Eurus now.

I would try Krio's suggestion. Add more motor timing.

FWIW, our 17.5 FDR here at our track is around ~5.6 - 6.2 . Of course gear accordingly to your track.

I have noticed this on my end too.

Hi twk-b,

(1) Mr Tekin states the following:
-- 1000rpm start / 6000 end (5K) with 50 timing boost will provide 10 degrees of boost per 1000 rpm vs.
-- 1000rpm start / 11000 end (10K) with 50 timing boost will provide 5 degrees of boost per 1000 rpm.

(2) Can you please expand on your statement:
---- "The boost/turbo is exponential...".

(3) Mr Tekin is stating a linear relationship, so when you say "exponential" are you talking more about a brushless motor's Torque vs RPM curve, or what?

Thanks in advance

Exponential is a non linear response. A higher value usually means response around zero is faster and a lower value means response is slower around neutral. Doesn't affect maximum travel, only reaction speed at the bottom and top end of travel.

It is not exactly an exponential function.

I know the definition of exponential - I'm an engineer.
And the rest of your response seems to be talking about something completely unrelated to the turbo/boost question I raised.

What he meant by exponential was not in how timing is added, but rather the effect of the added timing. Adding 10 degrees of timing doesn't change very much, 20 degrees has more than double the affect of 10, 30 degrees is more noticeable than 3 times 10 degrees, etc.

I completely understand what twk-b is saying.
I'm not doubting the non-linear relationship that twk-b stated.
What I don't understand is why?

As I asked, is it something to do with the Torque vs RPM curve of BL motors?
But I'm not convinced on that, based on the resultant curve (the black curve) from a few posts back, looked roughly linear (not exponential) - assuming the x & y axis is linear.

Mr Tekin applies a linear algorithm - so its not the source of non-linearity.

Has it something to do with the fact that the optimal timing boost map for a given motor is not currently applied, so we get something less than optimal which just happens to have an exponential look about it?

If none of the above, where does the non-linear relationship kick in?

Thanks
