K-Tuner available for 2019 RDX
#321
Ktuner 1.0.9.8 is available. see Version History
Looks like the V1.2 firmware update is the most interesting.

Okay, I caved in and bought the K-Tuner today. I hope to get stats before I install the tune so I can compare my results. I know most of you have the A-Spec AWD vs my 2020 Advance FWD, so I'm looking forward to see the differences between the two.

That's what I plan to do as well. I have a spare smartphone, so I plant to mount it and run the Tuner View App via Bluetooth from the KTuner 1.2. I want to monitor first before actually flashing. Plus I'm in California so....emissions concern me...passing smog and all. Plus, I'm still not quite sure how my Acura warranty will be effected with KTuner. I cannot find a straight answer.

So the quick adjustments feature has been out for a few weeks now, be interested to hear from those using it what they think? What settings are you using and what's the response to those settings? Also, what is the hit, because I now there is, to MPG?

The MPG is very subjective. Keep your heavy foot off and you will get better MPG. I just don't get enough time on the road these days to do comparisons. Once we get control of this 'bug', I will have the reason and opportunity to get more subjective results. As mentioned earlier, these settings don't increase torque or hp, it adjusts how the torque comes on. I need to play more.

I run Sport+ most of the time and am getting 21.6 average in city/freeway driving. Im heading across the Phoenix Valley this afternoon and back and expect to get 24 or so. That is cruising close to 80mph most of the time, as that is our “go with the flow” speed around here. Obviously if I stayed around 65mph I would get closer to 28 mpg. The latest adjustments are not that noticable to me, from the last update.

So, its been about a week since the Ktuner install. I'm loving it. I'm using stage 2, haven't tried stage 1 and I do not have a desire to. I'm very happy with stage 2. My quick adjustments are factory throttle response. I'm happy with the way Acura has them setup. The turbo response is set to 3 the highest and the boost target is at aggressive ramp 1. Both the wife and I are VERY happy the way the car performs now. Like others have stated, the RDX should have been this way from the factory. Hesitation is just about gone. Before, just trying to pass or merge into traffic used to be somewhat un-nerving, not anymore, both on highway and around town.
Yeah, we spent a lot of money on our cars and we didn't quite get the driveability some of us wanted but, for $449.00 to buy a KTuner to address these issue is well worth it to me and I'm sure most would agree.
As far as MPG I might be taking a little hit, maybe .5 - 1 MPG if that, it's nothing in my book. I enjoy driving the car now more then ever, so whatever MPG hit I take is well worth it.
Hey, I'm now burning rubber up to 3rd gear. Damn, I need some drag radials!!!

What kind of experience would Stage 2 bring to the Advanced model with SH-AWD and the Damper system?

I have a 2019 Advance SH-AWD and just flashed to Stage 2 with quick adj maxed except turbo ramp up which I have at Improved 2. Long story short, I love it! Sport is great; plenty of oomph and just all-around fun to drive. Sport+ is quite a kick in the pants, especially when you lay into the gas in a turn and the power rolls on. Really makes the RDX suspension shine. This is really what the RDX needed to be from day 1.
I recommend it to anyone who wants their RDX to be more fun to drive. Just remember to do the throttle reset procedure after you flash. Thanks to all on here who shared their knowledge of the K-Tuner system.

1. When ignition/accessory are off, depress the throttle pedal all the way in, . Then, turn on the car to ignition mode.
2. Keep WOT until the check engine light disappears. It took about 15-20 seconds.
3. Power down the car to off state.
4. Press brake pedal and start the car normally by pressing the engine-on button.
5. Procedure is completed

I've never had to do a throttle reset on ours. What led you to do so?

I have never seen a 'recommendation' from anywhere.
I do recall a fellow tuner suggest before to ensure the ECU had any inputs fixed before burn. I don't think it matters cuz the burn is just a burn, it is not learning.

I've read almost the entire thread, but I haven't seen any comments specifically on the impact to ACC behavior. So how does the tune affect the smoothness of Adaptive Cruise Control system?
I sometimes drive long stretches in stop and go traffic during rush hour on the highway and find the RDX's Adaptive Cruise Control too aggressive with both acceleration and braking. I would imagine that the ACC system is calibrated to the factory throttle response. But if the throttle response is greatly improved, the ACC would accelerate (even more) aggressively in stop and go / low speed follow situations, no?
Would appreciate any feedback on this.

Ok, so after you install the tune, how do the Comfort, Sport, and Sport+ modes behave relative to the pre-tune modes?
I think that what I'd like, is a Comfort mode that remains unchanged for the wife and family to use, but improved Sport and Sport+ modes.
Also, does the tuned Sport+ mode not use the last couple of gears in the transmission? I'm thinking that if the speed limiter is removed with a tune, then I would want the extra gears to be used when cruising at higher than "normal" speeds.

Interesting. Would you be able to elaborate on why that is the case, given that the throttle response and turbo spooling parameters have changed significantly, and one would assume that ACC would calibrated to the factory parameters.
Not saying I don't believe you. I'm just really curious as to how it all works.
Maybe something to do with the ACC being a closed loop feedback system where the throttle inputs are adjusted to a target acceleration rate and not throttle position?

My solution is to manually intervene the speed limit to smooth things out in Sport, or to switch to comfort mode. (Hondata uses stage 1 map for comfort mode)

no reason to 'cruise' in sport+. Sport+ has great reaction time at lower to mid speeds, ramps, autocross, etc. Comfort/Sport does just fine at cruising speeds. you also get to use all 10 gears, and paddle down whenever you feel the urge.

I'm perfectly happy with the acceleration of the RDX, but would like more customization of the drive modes. Does either K-tuner or Hondata allow one to select the suspension (I have Advance) and steering settings of "Sport+" mode, yet leave throttle, transmission and turbo settings in "Comfort" mode? I know. silly question.

no suspension, steering changes that I am aware of. The ECU only affects engine performance.

I put about 500 miles on the highway yesterday and have stage 2 with the quick adjustments set to max except turbo ramp which is set to improved. ACC worked as normal, didn't really notice anything different when it would kick in. Got about 26-27 mpg withe it set to 70-75 most of the time.
