I'm pretty sure it's the same for all years. It's very hard to tell since you're going so fast but u can definitely feel it go neutral if u watch closely

Default CO Dyno

Hi guys, I went with MileHIFCar to dyno this last weekend and here are the results... He put down the same numbers as last time he went with Rohi123 (Rohi's dyno is shown below mine, he has - IHE no tune)
Yes, it is hard to compare dynos on different days, especially since the weather in CO is so variable, but looks like we have the same peak power, with me having 10 more lb-ft peak. It would be nice to overlay the graphs and see the difference under the torque curves...

Keep in mind we are dynoing in Denver, elevation 1 mile, also the correction is SAE.
Mine IHE, RR tune

Rohi123 - IHE

Mine has the problem but isn't that noticeable since I shift right after the beep.

The 10 Ft Lbs of torque that you put down more than Rohi123 (in my estimation) has to do with the tune I'm guessing?? My guess would be that a few more runs on the dyno might have shown better gains

But as always I think those are pretty good numbers at the elevation here, and after talking to one of the dyno operators, he said that it was not corrected for sea level numbers?? So if that's true that's what our/your numbers are at mile high in elevation which is pretty good I think!?

so now that there is a few tunes on the road, has anyone noticed any decrease in fuel mileage ( when driving normal ) and has anyone requested a higher idle speed with AC off...I would like mine to be a little bit higher and seems too low , but maybe I'm the only one, don't hear much about it

I haven't seen this mentioned on this thread but for those of you datalogging your tunes and would like to see what your Knock Correction Learning Value (KCLV) and Knock Feedback Value are without the use of Techstream, you can do so by downloading the phone app "OBD Fusion" as well as the Toyota Enhanced Diagnostic PIDs.
​​​​​​
I recently picked up this tidbit from Rafi and Simon @ RRRacing and was able to easily read my KCLV (24 @ WOT) and to see if the car is pulling back any timing (-3 degrees at idle and WOT).
