Just watched the following video from PRI and it looks like Hondata will be releasing Flashpro for the 2019 RDX soon?

I would not expect much more power from Hondata on this.
The Accord adds 25, but it is going from 87 octane to 91. The RDX is already at 91 and it has the same TD03 turbo. They just have to dial the boost back at higher RPM's because of detination
and a small turbo cavitates at these RPM levels. Also, I would not completely buy into their massive midrange torque gains. When you floor the car it down shits and spends all of its time above 4500 where the flashpro gives you minimal gains. TD03 must blow very little air. Im sure there will be hybrid turbos shortly or you can put the TD04 in from the type r

They said stage 1 only at first and it will be 25 hp and 25 torque.

That's pretty decent. Any word on the drivability? As Jeff mentioned in another thread, it seems like torque is being limited in the lower gears for the SH-AWD model. Does the stage 1 tune "fix" this or it's something else that controls this?

Asked Hondata directly and confirmed the 2007 RDX Flashpro would work on the 2019 one...for those who are wondering!

Hondata uploaded the RDX site now:
https://www.hondata.com/flashpro?product_id=215

This dyno is of a stock RDX with Stage 1 and Stage 2 performance tunes.

Stage 1 operates in all 4 dynamic modes and delivers a 10 hp increase everywhere.

Stage 2 is configured for Stage 1 performance in snow and comfort and Stage 2 performance in Sport and Sport + modes. Stage 2 delivers 36 lb-ft of mid range torque and 28 hp mid-range power for a much more exciting drive.

I don't know much about engine tuning but that torque plot is lumpier than I would expect, seems they should've been able to correct some of that instead of amplify it.

I think there is some torque management going on, along with the transmission/AWD system doing some weird stuff. A FWD test vehicle would probably exhibit a cleaner pass.

The mystery is solved why the RDX is so dissapointing 0-60 and acceleration in general. I spoke with Hondata and the above dyno is for a SHAWD RDX. As you can see it puts out 220 HP in stock from. The Accord with no tune put out 260 HP. The RDX should be 20 more HP not 40 less. They told me the SHAWD was reason for the power loss. All this complexity and clutches etc sure kills power. It is pathetic that Honda cannot design and awd system that does not kill so much power. Another example of a compromised transverse engine layout that has to use this complex system to try to make it handle like a proper real wheel drive car. To bad, Honda has so much potential but chooses not to use it.

I think you'll find the transverse layout of the engine has NOTHING to do with needing to limit torque to the SH-AWD unit, after all the engine orientation is the same as on the Accord. The rear axle/diff is the reason for the torque control.........

I was not saying the transverse layout was the reason for the power loss. It has always been SHAWD. My point was because Honda uses a transverse layouts they have to use complex torque killing systems like SHAWD to make car handle properly.

I'm not sure if sh awd is the culprit.

The TLX sh awd is faster than the fwd one for 0 - 60 and 1/4 mile ET, and loses 2mph in the trap speed as expected when there's a bit more drive train losses and extra weight.

Likewise, the MDX sh awd pulls some pretty decent performance figures based in its output and weight.

It seems like there's more than just the awd system that is making the Rdx slower than expected.

Granted the latest motor trend test shows 14.8@95mph for the Rdx awd. That trap speed matches the q5 2.0t.

^ it's even more curious to me because I thought the version of SH-AWD in the RDX had the best torque capacity of any iteration so far (hence it's ability to use the rear more)?

Yea...though IIRC, it's always been challenging to dyno SH-AWD cars. We also know that dynoing the 2.0T 10AT accord was not straight forward. So now with 2.0T, 10AT, and SH-AWD, I'm not sure what the dyno numbers really mean lol.

All I know is that the RDX AWD didn't do really well in initial performance tests by Car and Driver and Motor Trend. But the latest Motor Trend test shows significant improvement and more in line with what I'd expect.

For comparison, Motor Trend got the following figures for the Accord 2.0T 10AT (tend to be a bit slower than what C/D would get):

0-60mph: 5.8s
1/4 mile: 14.4@98mph
https://www.motortrend.com/cars/audi/a4/2018/2018-audi-a4-ultra-premium-vs-2018-honda-accord-20t-touring-comparison-review/

And for RDX SH-AWD:

0-60mph: 6.4s
1/4 mile: 14.8@95mph
https://www.motortrend.com/cars/acura/rdx/2019/2019-acura-rdx-a-spec-long-term-update-review/

Being 550lb heavier along with AWD losses, I thought those figures make sense.

2019 RDX's acceleration appears a bit underwhelming when you compare it to the V6 RDX (Motor Trend sets it at 6.2 sec: https://www.motortrend.com/cars/acura/rdx/2018/)

The 2.0T has more torque and and the 10 AT has many more gears, but the 2019 model doesn't get to 60 mph any faster. It is not really more fuel efficient either, so they didn't really tune it to save fuel at the expense of acceleration.

So the 2019 RDX has more torque, comparable HP, more gears, a more aggressive AWD system, comparable fuel economy, and still a bit slower than the previous generation. That is unexpected.

Gladly give up 0.2 seconds for way less weight over the nose. The previous generation RDX was a comparable pig with respect to handling and steering feel (of course the AWD system was marginal).

Isn't the k20c rdx heavier than the J35 version? While I'm sure the K20 engine is lighter I'm not sure it's a huge diff. The J series is incredibly light for a big v6, doesn't have the weight of a turbo or intercooler, is SOHC, etc.

The weight balance got better by...I think 2 percent?

Yeah AWD went from 59/41 to 57/43 F/R.

The package overall is about 100 lbs heavier though.

That mostly works out to the front end weighing the same and the rear gaining the weight.

Did some digging.
https://jalopnik.com/this-madman-is-stuffing-a-new-honda-civic-type-r-motor-1820092729
"...the engine weighs 176 pounds more than that factory motor..."

According to SS, a D-series weighs 309lbs.
http://www.superstreetonline.com/how-to/transmission-drivetrain/1306-honda-engine-drivetrain-weights/

So if the info is accurate, the K20C weight is close to a H-series motor at 485lbs.

While the 2016 RDX tested by Motor Trend was quicker for 0-60mph, in the 1/4 mile it posted the same ET as 14.8s. And it loses out to the 2019 RDX for the trap speed as it managed 94mph, whereas the new one did 95mph.

Overall, I'd say they are as fast as each other. The 2G RDX has a bit more power, a bit less torque, and is a bit lighter. It also has an average joe AWD system that behaves like a 2WD system most of the time. The 2G RDX was also pretty quick in its class.
