I'm sure glad all of these questions are being asked and answered. I don't fully understand what alot of this stuff does and only being able to 'race' 2x a month with no practice in-between, I have to hit the track running. So I appreciate all of you guys for sharing your knowledge and Tekin set-ups

Didn't know a Novak SS could put out so much power until this past Saturday, thanks Tekin

No, you spend 4000 RPM at full boost. The amount of boost you specify is added linearly (think slope) between the start and end RPM, based solely on RPM. Then, the specified turbo is added in at the ramp specified after the turbo delay time (time spent at full throttle), independent of boost or RPM.

For example, if you specified 40 degrees of timing, 10 degrees of timing would be added every 1000 RPM between 4000 and 8000 RPM. So, by 8000 RPM, you'd have 40 degrees of timing added until the RPM dropped below 8000 RPM. Conversely, you lose 10 degrees of timing each 1000 RPM drop below 8000 RPM, until no timing is being added once you drop below 4000 RPM.

Try widening the start and end rpms...Try 5442 start and 20,000 end

I got that part... im asking about the RPM *AFTER* the end RPM setting.

Start RPM: 4000
End RPM: 8000
Actual motor RPM at end of the straight: 12,000

In this scenario, boost (not turbo) ends at 8000 rpm. If so, then you WOULD have 4000 non-boosted RPM. Correct?

12,000-8,000=4,000.

No.

10 degrees boost at 5000 RPM
20 degrees boost at 6000 RPM
30 degrees boost at 7000 RPM
40 degrees boost at 8000 RPM
40 degrees boost at 9000 RPM
.
.
.
40 degrees boost at 12000 RPM

I think what Davew is asking, Say you put the end rpm at 10000. The motor actually goes to 20000, what happens with the Boost for the 10000 after the end rpm has been reached?

Stays at the specified amount, which is reached at end RPM. See my previous comment. All you're specifying by the start and end RPM is the end points of the line that is used to determine slope. The closer the start and end RPM, the more "violent" the boost hits. The farther they are apart, the "smoother" the boost comes in.

AHHH ok. So the end RPM stops the boost 'ramp', BUT continues to hold selected boost value through to the end of the actual motor RPM range.

So setting boost end RPM to 30,000 for my 8.5 would be totally unneccessary. All i would be doing is softening the midrange feel by setting end RPM that high.

That explains (i think) why i have been able to get away with ramp 2 for turbo with .02 delay. With my boost end RPM set so high, i wasnt at full boost value... so i wasnt overtiming the motor.

Basically, i was full turbo halfway down the straight, waiting on my boost value to max out with FDR at the end.

(?) <--- LOL

Boost and turbo don't disappear once they've reached their max value. If you had a mile long straight away at your track and your motor hit 50,000 RPM you'd still have your full boost (lets say 50) and full turbo (lets say 10) long after your end RPM or the turbo delay was reached.

Surprisingly, no. A Novak Sentry data logger showed that my 17.5 Duo1 was hitting between 29,000 - 32,500 RPM on a track with a 90 foot straight. That was with a FDR of 6.56 and an end RPM of 18,000. Sounds like a 10.5 down the straight.

Depending on gearing, you could hit that RPM.

I'm having problem calibrating my M11 DSS 2.4 GHZ to my tekin I just switch to the new software 212 and I'm not able to calibrate mt radio. The ESC only recognized the radio and neutral positon.
