RD doesn't have figures at wheels??
10.8% increase in power and 11% increase in torque in P2 mode. This is sad as the advertised gains are 30% for the dualchannel. I would like this to be clarified by RD.

Was the run made after locking it in 4th?

This clarification maybe inappropriate for this thread, mods please feel free to move if needed.

The calibrations on the device are vehicle spec and many of them exceed the claimed figures, but when we take in safety, smoke, noise, harshness, torque limit to autobox, etc. it has to be set to level that you currently have, however there is a lot of scope for improvement on the crysta with a custom tune, as you can see from the attached graphs below for the same vehicle -

Torque
4000 RPM - 300Nm to 402 Nm -> gain of 34%
4500 RPM - 242Nm to 333Nm -> 37.6%

Power
4000 RPM - 168 HP to 224 HP -> gain 33%
4500 RPM - 152 HP to 208 HP -> gain 36.8%

Do note the sharp rise at 3200 RPM, thats the OEM ECU safety limits clamping gains pre 3200RPM.

Thanks a lot! Though these are only numbers it feels good to see it though i was impressed with power delivery already. The real world performance of the vehicle when i drive it closely matches the graph you posted rather than the one i did earlier. I can relate to the graph the much improved midrange with the box. Next time when in Bangalore i hope i can visit you.

Not sure if the Vitara has curves.

XUV has plenty. :LOL:

On a serious note I guess we should wait for the 180 BHP version of the XUV before we put it on the dyno.

Hi RD - of late Iím following the RD dual channel box thread, Iím inclined towards having the same installed on my Brezza. Can you tell me the real time bump in power and torque figures the modes offer? Also, I do want to keep the smoke and noise levels in check. I stay close by to your outlet near Sarjapur Road. If you can give me a first hand experience of this box, I can pay a visit so that to drive and experience it real-time
