The vw motor has direct injection that's reasone number 1 why it makes so much more power. Also if you look on say APRs web site their numbers are crank numbers usually.

I'm on my phone I'll post more comparisons later. Your better off comparing the new type R motor to the 2.0t

RDX10

Oh, I wasn't aware that DI had an effect. Thank you for mentioning that to me, I really appreciate that! I also was not aware that they were crank numbers so I also appreciate that too.

I honestly feel that the RDX is plenty powerful enough from the factory but it is always nice to have more power! I will be doing Hondata though for sure. I suppose $300 for the gains that Hondata does provide is pretty sweet.

i think the vw motors were sand bagging a bit more and that's the reason for such a big jump in the STAGE 1 tune as far as needing bolt-ons the Acura has a bit of a handy cap in that the direct injection is more flexible in how it delivers fuel and its effect on emissions. and Honda went for Ultra low emissions and screwed us with that primary cat! as far as what the stock turbo can do I think if someone wants to max it out they can hit a mid to hi 13 in the 1/4 mile and probably 280+ whp.?. the injectors are a must change if you get a turbo or all available bolt-ons. the other bottle neck is the stock maf sensor and I'm working on that.

RDX10

Yes makes sense! I also read that VW and Audi are notorious for under-rating their engines power figures and it is possible that they were making closer to 220-230hp/230-240tq to begin with.

Is there no way to remove that primary cat? I am sure if it was that simple it would have been done, but just wondering.

Hondata adds something like +20hp and +30tq IIRC, adding a downpipe, injectors, and a better exhaust would probably help a lot. I really doubt that you could get 280whp easily though, the SHAWD sucks the power right out of it, along with the rest of the drivelines parasitic drag. But I would love to have 280whp! I kind of wish they just stuck in the 3.5 or 3.2 DOHC VTEC V6. That would have been sweet! Then again the RDX wouldn't be nearly as agile I would think.

with 800cc DW, ETS topmount, CP-e intake, RV-6 downpipe, and Flashpro I made 269whp 279wtq and im not a "tuner" but tuned the car myself.

csargemg

I didn't post good numbers (only 200whp lol) but there were odd things going on in my tune right at this stage as it was the only time I could get dyno control, and it was super rich as part of the knock control tuning process.


Going to be able to post numbers when all is done for what I feel is my 'modest' mod list: RV-6 dp, ETS intercooler, 800cc injectors, flashpro. Ideally with the dead spot ironed out and everything finalized I'll be able to at least match the previous numbers. If not, I'll attempt a dyno tune and see how it goes. Then we'll have a great grounds for comparison for everyone, I think, as I imagine that my mod set will likely be a common starting point as it provides a great 'base'

GSJake

That will be.

Did you get get a CEL with the RV-6 DP and the 02 fouler?

RDX10

I thought you meant originally that you could get 280whp with stock hardware and just tunning via the software, that is why I meant that it would not be easy. But with those add ons, I think it would be very doable.

Those numbers are very impressive! I imagine at the crank it must be making well over 300hp/tq. I hope to be able to get your numbers with mine if I get one.

hypnotini

also....stages is a loose term cant really compare stages amongst cars.....like compare a stage 3 subaru to a stage 2 tiguan to a stage 4 evo to a stage 2 dsm.....you see where im going with it. i could say my base tune was stage 1 i could say my current tune is stage 3 the good thing about hondata fp is you are able to constantly tweak....no set stage crap. i tow "stage 2 " subarus all the time in colorado because the stage preset tune is shit and screws there stuff up. :-)

GSJake

Are you just getting the ECU flashed or are you going with a Flash Pro as the price indicated just the re-flash?

RDX10

Excellent point! I totally agree, I wasn't comparing different stages, but just that I liked that there were different stages. I am not familiar with turbo's so I don't think I would even know how to use the flash pro - hence me looking to get tunes by VIT.

I am still not sure if I want to get the whole flashpro or just go for the re-flash. I was originally indicating just reflash with that price, but I want to try and get more power out of it and may get tunes from VIT, but obviously that would mean I would have to purchase the flash pro as well.

TheWrench116

the "canned" tune from the hondata reflash leaves a lot on the table. but if your just looking for a few more HP then it might be right for you. but if you get a taste you will most likely want more. it would be a shame to spend it twice. trust me on that one I've bought 2 intakes and 2 intercoolers and 2 sets of injectors...

RDX10

I completely agree, I want to have access to a bigger bite and "canned" is an excellent way of describing it. I think I may hold off on both the Hondata and the Flash-pro until I decide what I really need. I really want to decrease turbo lag, much more than going faster or getting more power, so on one hand I think Hondata is enough, on the other hand, I know myself and I like POWER!!!!!

kingkong222

I'm considering getting a flashpro should I be concerned if I just run the basic map from hondata? I'm not interested in special tuning at the moment. Kinda confused with all the threads about problems with flashpro.

uh

hues10

KingKong, I bought the Flashpro about a month ago and it was super easy to install. My impressions from a novice (right now) and from what I have read, is that the turbo spools faster at lower speeds, so when I punch it even a little at slow speeds, the boost pressure gets to full boost quicker, and the acceleration is smoother. I don't know why, and I am sure someone else can explain it much better and in technical terms. Now I am looking forward to putting on a couple more mods and getting a tune just to see what it can do. Can't let everyone else have all the fun on this forum. Call it my mid-life crisis.

hondata base maps are VERY safe but close the gap some on what is possible with all the stock hardware (turbo, injectors, intake, intercooler, down pipe, ect.) once you start replacing the stock components then its mandatory to have it.

a vit tune will get you the most power and reliability also better MPG

the flash pro is a 10/10ths tuning solution. you will have the best possible drivability and power potential IF you know how to tune OR you have a good tuner ( VIT VIPER ) and what's more is Doug (hondata) and Vitaliy (vit viper) are constantly working on furthering the "cause". I think they really want to see what this platform can do regardless of weather its a stock vehicle or its going to be a weekend warrior.

RDX10

Haha!

kingkong222

thanks for the comment. I had the reflash before and it was wiped out by the dealership when I brought the car in for service. Now I'm back to stock and was wondering how is the reflash power compared to Flash pro from your experience. Any difference? I've seen the numbers from Hondata and as I recalled correctly they should be the same. But I want to know your personally experience from someone who went from Reflash to Flash pro. Thanks for your inputs.

Major difference
Smoother driving it's actually calibrated for where you live and drive you'll get better mileage it's Tailored to your vehicle it's not a cand tune

Tomtwtwtw

You make some good points. In my previous car, you could get a warranty-backed reflash good for 30 hp / 60 tq, and the aftermarket tuners were capable of much more with simple software. The potential gains in this car, at least so far, are not nearly as much. There could be a number of factors, but primarily (at least so far), the biggest barriers seem to be fuel (stock injectors can't support much more than stock power), and issue with overboost (appear to have been fixed with most recent Hondata release).

Software solutions will definitely take some time with the RDX, as the enthusiast population is not high compared to other cars, and this engine is not available anywhere else. With the relatively small size of the aftermarket, that's just par for the course. The things guys like KenB and Wrench are doing though - that could open some doors for some the more "casual enthusiasts" like myself.

GSJake

What car was that Tom?

Tomtwtwtw

'08 Cobalt SS. In my (likely biased) opinion, a diamond in the rough. It was as quick around a track as the Camaro SS of the same year, yet easily topped 30 mpg on the highway and rode only slightly stiffer than the first gen RDX. Aside from the cheap-feeling interior (albeit functional and well organized), it was a fantastic all around car.

TheWrench116

another cheap Runner dodge neon (hi) SRT-4 {c ya later}. those things were stupid quick and with bolt ons and simple shit were even more ridiculous! albeit the shift knobs came off when you snatched second gear but man were they fast for the money.

Tomtwtwtw

SRT-4 got a lot of hate, but when it came out you had a 4-cylinder econobox that could run neck and neck with Nissan's brand new 350Z. For the Chevy, 300 whp / 350 wtq was achievable for less than $1k into the car. I spent almost that much on an intercooler for this RDX! Never lost my shift knob, but I did lose the little plastic cap of the shift knob that had the gear diagram on it. And, ironically, that was the only thing that ever went wrong with it in my 85k miles of ownership. Really was a great little car, I was just ready for a change.

Sometimes I think I should have kept it along with the RDX, but if/when I have a real dedicated "fun" car, it'll be something that spins the rear wheels.

Furio8685

What kind of mpg should I expect fully bolted tuned by vit? Curious to see what kinda mileage are you guys getting.

Tomtwtwtw

That will depend more on your driving style than the tuning. Some of the bolt-ons can potentially give a slight increase in mpg, but if you are the heavy-footed type it could also go the other way.

Let's put it this way...if you're tuning your car to get better mpg, you're wasting your money.

TheWrench116

iTrader: (1)

tune for power and drive gently you'll get good results.

hues10

Have to agree with Wrench and Tom, best way to get maximum MPG is drive with a soft pedal (as in don't engage the turbo much). But on the other hand, why buy a turbo without using it. The Hondata Flashpro seems to give the car more low end pickup is what I noticed with a slight bump in MPG (only one tank though so don't quote me). Tomtw know the specifics about leaning out the mixture. On the other hand, the Sammy Hagar song applies when the road opens up (can't drive 55!!!!!)

well he could elaborate some on it that's all I'm saying... he tuned it so it would be nice to see the mod list and numbers listed someplace. but not everyone is about helping the cause so if the individual wants to remain obscure I guess we are free to guess and wonder.

thoughts for the day.

KenB350z

Yup

GSJake

Is he\she a member on here? What mods to get to the 300hp number?
Ken,
You are going to Vit and have him personally tune your car?

KenB350z

No need to guess or wonder, we all know it's rdxchris710. 300hp club, must be nice!!! In my New York accent "get tha fuk oouutta here".....

KenB350z

Yes, I will be over in the west coast to visit him soon. I emailed him and after a few emails he asked "what car?" I was hesitant, but told him and he knew I was about to ask about the RDX. We went over the mods that I have and future mods and decided that this particular build could not be properly tuned via etune.

AlLtHiNgSaCuRa

If he tunes his own car why did he make a VitTuned threat?

KenB350z

KenB350z

My numbers should have been higher, but I did come across something that was holding me back. The number 2 injector didn't have an O ring on the manifold side..



But, I do know Miyagi Motorsports Acura RDX broke 300hp though..
