At the IIC, the CRC guys were clearly faster on the straights by enough margin to make the others (including Hupo Honigl - no mean driver!) look slow on the straight, no matter what Tekin threw at their speedos.

If this were a timing issue, then the Tekin guys would have equalled the AE BD during the week. Since they couldn't, it seems to me that AE have come up with something else. I hope Tekin will close the gap, but I think eventually it will prove to be new hardware.

You tell that to previous IIC, Birds, Reedy champs, that they are .5 off pace because of thier car setup, or line, it's NOT the case this time, it's like having a 13.5 motor in a 17.5 class.

They should run in the same class so all the driving skills mentioned above come back into play. Same speed=same class.

Then hope you don't go up against a 17.5 car with an AE speedo, u'll think he has a 10.5. lol.

not true,i ran against one last week and we where going back and forth for the tq spot, it came down to driver error for tq

I have the same problem with the Speedpassion. The Tekin is by far the fastest motor that I have.
It has no braking problems.

One advice. set your Turbo delay higher. Set it around 0,8 to 0,9sec.
The 0,2 to 0,5 is much to low.
You will notes more infield power when you higher the Turbo delay.

Try to gear heavier and set your Boost on 12.
Turbo on max
Turbo delay 0,8sec
Brake with a lower Boost on the speedpassion is better.
Just try it.
Motor temp of the speedpassion of 70 a 75C is better. It has more power in the infield than.

My best lap times came with a lower Boost and a heavier gearing.
The brakes were also better with this setup.

As you get the Tekin motor, gear it light. Not light light but very light.
I had it geared 6,3FDR wile the LRP drivers were geared 5,2 to 5,7 with a SPX and 4,7 with a LRP TC.
Boost 15
Motor timing 8 to 10
Turbo max
Turbo delay 0,7sec
6.3FDR

i've tried this setup and the improvement was significant. i went from 20 to 10 boost... and geared up two teeth on the pinion from 27 to 29 (30 does not fit).. Temperature was still around 60C.... so I could push it harder... the turbo entering was noticeable.. so i guess i could make it a bit earlier... from 0.7 put it back to 0.5... i'd still like more breaks if possible :)

that's until the new tekin pod arrives :)

thanks for your tips mikky.

Yes, the performance is perfectly explained by optimized timing. Here's a good comparison:
The RS with v200 is like a 3 speed transmission. You have 3 timing sets that are each optimal at a given rpm (not including the ramp up time for turbo).
The AE BD could be considered a CVT (without the friction losses usually associated with an actual cvt). Proper programing will produce the maximum amount of torque at any rpm.

hey guys,i've been through the last 80 to 100 pages looking at info, i would really like some help on gearing my tc5 ..... i'm running a losi 17.5 b/l with a rs esc. the losi motor will not allow timing changes on the can so all my setting are in the esc i have 25 on boost and 20 on turbo . my track has a 120ft straight and is semi techinal infield. i need gearing recommendation
i run rubber tires in tc class indoor asphalt. :confused: thks 4 your support!

Not sure I understand your explanation. When I observed the AE BD speedo in the CRC cars in LV, the advantage was clearly down the straight. On the infield there was much less difference.

I understand that if the timing is applied all the way through the rev range, it would be like a CVT, and that would help in the infield. But, if the Tekin is applying (say) 45 deg timing at full speed, and the AE BD is doing the same, then why is the AE BD powered car faster in a straight line? Are you saying the AE BD applies more timing? If so, how do they overcome the heat issues with so much more timing? I don't think this is a timing issue alone.

Tekin say they will release new software that closes some of the gap. I think the reason they cannot close all of the gap is that the AE BD is doing something else, and that something else is related to the hardware. Can you explain your theory more, please?

As far as I know, the AE BD has only been comparatively observed in a closed course scenario. Because you are on a track with limited time to accelerate, the esc that more accurately applies the "correct" timing while under acceleration will accelerate harder and thus be faster on the straight. On the infield you are usually limited by your left/right traction as to how fast you can go and that comes down to car setup. Also, your speed is fairly constant and setting the correct boost timing in the tekin will provide a very close approximation to the optimum timing for most of the infield. $1000 says (not making any official bets:lol: ) that if you take a tekin and BD to a drag strip and set the tekin timing to the same timing the BD applies when at top speed you will have two cars hitting the same top speed. However, the BD will reach this top speed sooner than the tekin with the current v200 software.
