So after talking with LHT Performance the other day about getting my reflash down I found there is a guy in tampa rollin around with over 450hp to the wheels ON THE STOCK ENGINE... Seems he used an AEM stand alone, LHT made hima custom turbo manifold for a swap, and intercooler piping set up for a relocate. but the iswsue is he lost all of the features to his RDX, had to install custom gauges and everything. The problem is I am anal about my cars, they have to look like a finished product, and remain their stock creature comforts. Even the E46M3 I race is wiretucked, and clean as hell... so not even for a 450hp soccer mom SUV would i trade my interior features. So the guy at LHT says, well is hondata made a K-Pro or Flash Pro, we could do anything and keep all the things we love about the RDX, and also it seems bigger companies are waiting for a tunable piggyback system before they do anything i.e. Spoon... Talked to hondata today. "We have no plans on making anything else for the RDX"... "No matter how many people on the forum show interest or place pre orders" WTF? what kind of company is that... Can someone out there just make a tuneable ECU so I can have my cake and devour it too...

sadly, unless a company wants to devout their time and money into a sinking ship, you probably wont find what you're looking for.

ya its a real bummer that such a potential vehicle is a basic flop from acura.. problem is its the only engine they offer for the specific vehicle.. if they put the engine in other vehicles then there would be more light on the subject but for now and possibly forever it will remain a reflash only type of ecu. maybe you should ask COBB to make a flashport for it.. they like to work on turbo vehicles. or maybe try Haltech over AEM i know alot of TSX people have better luck keeping more features with it over the AEM

xrvman

uhg im just gonna pay out the ass, and have a one off RDX, built motor, 600whp, down tuneable to 300whp so when the woman takes it she doesnt kill people... all the features in place... sleeper soccer mom

or are you speaking out of your ass!?


DO IT!!!!!


Speak to J&R performance.
Rodney just recently built a NEW ECU for the 3.2 v6 TL's.
totally tunable, where as we've had trouble tuning the TL's before because the stock ECU would always re-write over the flash.

this new ECU cost $1400 for us v-sixers.

if you lend rodney your vehicle, I'm sure he can come up with something. but it wont be cheap


Check this thread out and get in contact with Rodney!

nah man I want to walk on them srt and subie boys in my SUV lol... Im tired of seeing all this potential under my hood and not having anything to do with it... Yeah I was VERY close to the JR thread followed it from day one, back when I had my 08TL... actually talked about turboing it before Rodney ever even was in the picture... Everyone on the TL side of the forum saidf it Couldnt be done because of the tune... well rodney showed them... problem is, IDK if there is enough interest in the product for anyone to play... especialluy with the non turbo and hybrid redesign that is going into effect on next years RDX

so what you're saying is you're all talk.

bluecarbonfiber

Thats nice to know Justnspace.. is it for the TL-S also? and what years is it good for?? didnt really notice the answers to those (just skimmed over)

justnspace

iTrader: (1)

yes, its for the 3rd gen TL, which includes the TL-S. 04-08.
it can be ported to the 2nd gen TL and the 4th Gen TL.
a fully bolted on TL can extract 25-30hp extra with this new ECU.
you do have to get it dyno tuned, as there are no "base maps" per se.

this new ECU has the abilities to change lots of parameters, but again at $1400, its pricey.

bluecarbonfiber

ya.. its no reflash so the price is decent specially if someone wanted to have a turbo for the car.. that is a great thing for TL owners.. they finally graduated to tuneable options like the TSX too bad hondata couldnt of stepped up and did it..

justnspace

iTrader: (1)

^yes, exactly. It's geared towards the turbo crowd!!!

Hondata didnt want to spend the money and time.

Joe Las Vegas

Hondata is the only ecu tuner for the rdx, so we should give them credit for doing something, it's a good tune and the only one available.
This 4 banger dishes out 240hp stock, 260 w/hondata tune, best 0-60 time for any crossover out there, pretty dam good overall IMO.
If a ton of hp and a sub 4 sec 0-60 time is what you want, then get a 2008 GCSRT8 and slap a Vortech S/C on it, you'll get hp but run 10 mpg, and 2 open diffs vs. SH-awd.

JCRDX11

Yes we do give them credit for hooking up the RDX owners.
But it would be good if they can team up with AEM or any other aftermarket piggyback system and hook us up even more.

If money is a factor that there is no more reflash orders would be placed.
I would suggest to work out a deal with the other vendor to come up with a profit split on each order.

This way both vendors are happy and also us RDX guys.

bluecarbonfiber

^ agreed

sure you can go buy a cherokee srt and have redonkeylous HP but what fun is it when the HP is already there?? rather have something that takes some brain power to make some hp and have people think twice about when pulling up to a line next time they see one just IMO

SinCity

I wouldn't mind having a GC SRT8. Modded, those things haul serious ass!

windowlickingood

im still waiting on a open source or cobb solution.

Kaze66218

Last week, I called around since I'm going AEM ems on the car, why not check into AEMs solution

There are piggy backs that really piss off our ecus and there are devices that actually remove the routine from the ecu altogether. Air is constant, Fuel is what we tune anyway, ecu can keep ignition. Only problem is hacking the ecu harness, well until a patch harness is made.

Those devices are mislabeled IMO. On that note WSPY should get credit for this, AEM FIC according to Henry@AEM tech, their model 1910 should "be the right one." they haven't tried it yet.

(shibby) Until this is verified any one looking for more than bolt on performance 220 plus hp should hold off on reflashing.

wspy

And no probs with hacking the harness either

Then plug this into what? I want to tune boost... without the ecu going into limp mode... or the possibility of a turbo swap

windowlickingood

if you are going to tune boost, you would need to tune your fuel and timing also. you just cant add boost and call it good.

Kaze66218

Lol this turbo would rock it, if it didn't vary the flow at higher rpm: boost looks kinda like this 15-19-15-10-6 psi (hondata, per my dyno) and boost is controlled via solenoid anyhow. Boost is almost non existent in the upper rpm band. I've seen 2.2L Honda engines with 9#s boost with more power 300 range, than our RDX mine is 210-220 (dynajet, depends on fuel and temp.)

WSPY, a while back i was messing with the vac lines. That little tweak I played with was the variable flow control vac line, I was under full boost, full time, and stupid lean. But its not safe so i quit writing about it.

WLgood is right increasing boost increases the volume of air that is mixed and a:f needs tweaking.

godfather2

lht is the only tuner i let touch my cars. i'd listen closely to what john and paul advise

wspy

So Kraze, what was the full boost psi you were getting with the 'tweak'? If it was higher than 17-19psi did you not get a check light or anything? I'm curious because of what Church was saying about the 'finnickyness' of the ECU ect.

xrvman

No I get this... but what standalone are you going to use with that harness...

Kaze66218

Yeah I got a CEL, but after returning it to normal, and 5 days later it went away. I was wondering if Mr Church knew what was going on. He knows alot about the k series ecu. If it were up to him there'd be a tunable solution for everything.

windowlickingood

what is the max efficency of the turbo anyways? like what psi would it start choking it self off at? a better way to get boost controled in the top end would to maybe add a manual boost controler set to stock boost. and or changing out the wastegate actuator for one that has a lil stronger spring tension. sometimes you can jerry rig it with a spring that will add tension to the wastegate arm so that the boost isnt tapering off so much at the top.

also maybe look into these people for a stand alone/piggy option http://www.hydraems.com/ the 2.7 looks pretty promising

Kaze66218

The wastegate is internal, aka variable flow valve, it is controlled via solenoid. It can't keep up with the air while adding fuel.

windowlickingood

Im aware that its internal but there is still a wastegate diaphragm outside the turbo

windowlickingood

but also what im trying to explain is that you wouldnt be really adding more boost, its just able to keep a better boost curve and not hit a brick wall at high rpm

Kaze66218

Yeah, 6 or halfdozen the other, the waste gate/ vary-blow flow. Exhaust stays internal the diaphram/actuator that looks like a waste gate is the vf device and acts the same imo. Wastegate/vf gases are fed into the dp allowing the direct bypass of the compressor into dp. Since it operates on a solenoid within ecu parameters the marketing engineer can call it variable flow. The Acura wastegate is impressive in design IMO but it's all eye of the beholder.

The variable flow gate is open from 0 to 2500 rpm then shuts to build pressure inside the snail, and around 4.5-6g opens slowly again. It'd be nice to have that power hang around till redline. Hence my neutered comments on the turbo.

windowlickingood

just thought of this, but what is hondata using to tune the ecu? i mean why cant they just release that?

H22A_CD5

iTrader: (3)

Thats probably proprietary based on an agreement with Honda. I remember hearing that Honda and Hondata share information to a point. Hondata making what they use to develop ECUs available would probably be in violation of said agreement if there is one at all. And from a purely business standpoint (especially in the aftermarket vehicle parts industry) if someone can copy it they will. Giving their secrets away would be like giving their profits/customer base away IMO.

windowlickingood

dunno about that.. just assuming that they would be using something like kpro, i mean if they can obviously tune it, then it should be a standard tuning program. if all it took was just the 500$ com device that would let you in to program, im sure there would be a few programs that i can think of off the top of my head that would be able to tune the car.

H22A_CD5

iTrader: (3)

But therein lies the second part of my post. They would be giving away what makes their product unique.

Kaze66218

Yeah it may, but I highly doubt a K-pro or Flash-pro will give away trade secrets. Look at this how much is lost if say the "kids" get their hands on a 07- present RDX. Young and dumb... Sure it's gonna happen, and the only solution is to go elsewhere for more than reflash performance. Hondata's gonna need to look at it, Damn'd if they do, Damn'd if they don't because some other company is gonna figure it out and carve a niche, simply by listening to consumers. If you take a seat and watch, you'll miss-out.

I wonder if Cobb would step up to the plate for us RDXer's.

windowlickingood

thats why im saying go to the forums and mob up and let them know that there are people that want it. most of the work is already done. they just need to write the definitions for the accessport and we would be able to break the ball and chain from hondata.

JCRDX11

Any update from Cobb? I just email them myself also.

windowlickingood

No but it will be better to have people to join their forum to express interest. Seriously if that thread blows up they would more than likely consider. People need to stop settling for just good enough
