Hondata RDX Reflash - End User Reports!!!

2008 RDX too old for mods
My 08 RDX has over 100k miles and not sure if it's worth getting the hondata. I'll want intake and exhaust after my first mod. But I guess my RDX can still be reliable with over 250k miles. The first 3 years I was averaging close to 30k miles a year driving back and forth from NY to DC, but no longer to that trip. so Now i shouldn't put more than 15k miles on my RDX a year. When will the original factory exhaust and manifolds need to be replaced anyways?

Can't imagine you needing to replace the cast log exhaust manny, lol. I know a great guy in that dept, pm when you can. I am guessing that's not what you meant, further clarification needed.

So after reading the reviews and it seem to be a great mod for the RDX but I am still concerned with the gas quality that we have here in WA state. The best I have found is 91 octane + 10% Ethanol. From my research, people have been adding octane booster or do a mixture of race gas with 91 octane; to prevent knocks....
I have the reflash on order but if I have to put in race gas or add octane booster every time I fill up, this may not be so beneficial. OR be on a constant worry that using 91 + 10% ethanol will be more harmful for my rdx than good.
Thanks for the feedbacks

Lol I hope you were kidding about driving all the way down to OR for some gas... And classifying "driving hard" is it on a track event or sometimes doing a sprint here and there? I'll just add octane booster all the time then because I don't know when I'll get on it or not, just to be safe...

91 Octane + ethanol is our winter blend here in New Mexico. My RDX with the reflash runs the same with the winter blend and with the 100% gas in the summer. The only downside with ethanol is my overall mpgs usually go down in winter because of the ethanol (about 1 to 1.5 mpg less on combined driving).
When I visit my in-laws in the eastern part of the state, they only have 90 octane at the pump. The RDX runs fine with 90 octane until I can get back to ABQ to use 91 again.
I think it would be a waste of $$$ for race gas or octane boosters.
#207
I think octane booster should help with the problem, race gas wise would be expensive. I'll just wait and see once I install the ecu back in. Wonder if the MIL would blink like a kpro if it knocks.

As for engine, you could do a compression test, that will give a good idea of condition your engine is. Blue smoke on startup, coasting and after long idle could indicate age/problem with the engine or turbo as well. If compression checks out and there is no blue smoke and no abnormal valve train/bearing noises, then engine is in good condition, and should last for a long time.

I decided not to go with the Hondata reflash. After a seven word e-mail reply regarding the TL ECU and this unwarranted arrogance (last quote):
So, this^ is what cost Hondata my business.
Gave my $300 to cp-e instead.
I wish Hondata would release the RDX reflash program to their authorized dealers and just charge them a royalty fee when ever they perform a reflash on a customers' vehicle. From a business point of view I think they would earn more $$ and incur less FEDEX/UPS expense and the dealers would be able to sell additional services as well.
How can we get Hondata to buy off on that idea?
Just a thought

I was refering to Hondata not getting any money from me period. However, that is good to know because my local dealer never replied to my email inquary. I think the car gods are trying to tell me something.:shakehead

You can sugar coat a turd... it's still a turd.
#216
any recent updates on this? I will have my 08 RDX AWD this week and really want to get this done! I'm more concerned about the MPG's, gain in performance and if in fact it does void any warranties? I did purchase the honda care and was curious if anything were to happen to the RDX that the dealer would just void the warranty or what...
#218
Yahoo found a Hondata retailer about 1h30 from my town, I might go there directly instead of waiting for the ECU to be shipped.
Does anybody knows how long it take to actually do the reflash? An hour?

confirm that retailer can do it in shop.. most will just send your ECU to hondata then they send it back to you.. only time i see them do it in shop is if they have that flashpro with multi keys..

Nevermind I just spoke with them!
If I drive there, they will reflash my ECU by simply hooking up to my OBDII port, and it takes around 6minutes... lol!
But since I am in Canada, it's 350$ instead of 295$... Grrr!!

#222
I'm looking at the Hondata website, does *Kpro Installer* mean they will flash the ECU in house? And not have to send out the ECU to Hondata in CA? I found a few dealers locally but only one Kpro Installer in the NYC area.
#223
Forget it, I see on the Hondata dealer map it identifies if the dealer does on site reflash.

Just got my reflash done by Trackmasters in Huntsville Alabama Friday. They were super nice and did the flash onsite in a matter of about 10 minutes. The car does feel a bit quicker and more responsive, however I thought I'd try one redline pull in 2nd gear in sport shift mode and it redlined at 6800 just as before. I'm not too concerned because I would probably never go to 7100 but it just makes me wonder...
#226
Got my Hondata reflashed ECU back today, and well... I'm getting check VSA and check emissions lights when accelerating on to the highway. Anyone else experience this issue? Just filled up the car with 93 octane, so I don't believe fuel quality is an issue. Any suggestions are greatly appreciated. My RDX is 2011, all stock except the ECU.
#228
Understood:
- P0556: Brake booster pressure sensor circuit range/performance problem
- P2646: rocker arm oil pressure switch circuit low voltage
- Also, ignition now starts at 2 position instead of 3

shame you cant send a datalog ... seems like you got an rdx that wasn't maintained well. there are screens in the head, they prevent particulate material from getting into sensitive areas. they are subject to sludge if a high quality oil isn't used and frequent oil changes aren't don they get blocked. as far as the booster code goes ...?... theres a check valve in the vacuum line that goes to it. check it to make sure it works correctly.

That's not right. I have flashed twice and never had that...(2010 AaWD).
#232
Not to pile on, but I did the Hondata Flashpro base map on my 2011 RDX, and didn't experience any codes or problems. Sorry you are having such problems, but the potential solution is have the company put the ECU back to factory settings and see if any codes come back up. Only way to tell if the reflash is causing the problem. One reason I bought the Flashpro so that I could always reset it if needed.
#233
Thanks everyone for your insights. I contacted Hondata describing my issues and they had it shipped back overnight. As it turns out:
They put the older reflash for the 07-10 model years instead of the 11-12. They quickly identified the issue, put the proper program on and paid for all shipping costs FedEx priority overnight (FedEx however was less impressive in the customer service department). So they made a mistake, we all do, but I'm glad they owned it and I got some "free" Hondata swag out of the deal.
Not much to say about the performance that hasn't already been said here: good low-end gains and boost builds up much quicker. I am very pleased with the reflash.

Hi I just finished Flashing my 09' and adding K&N SRI on sunday afternoon. Spent Friday/Saturday testing just the base map reflash: felt the low-end gains and boost in D or Sport mode, then added the SRI. Trying to figure out if it feels any different but sure sounds different.
Question: I noticed after a couple of hours driving around a return to a bit of lag...would IAT be an issue with or without the SRI?

#235
SRI aka Hot Air Intake will give you bog/lag from a stop or very low speeds; until you get up to speeds w/ enough cooler air flowing through the engine bay, it's unavoidable. This is especially noticeable in warmer seasons.
#236

Totally makes sense, I noticed it after stop and go traffic on a hot day. I finally got back on highway/freeway and felt bog/lag for a bit.
I'm sure its been discussed but are any nominal gains with the SRI worth it (I assume Hondata calibrated to cover the K&N SRI IAT's).

RDX Reflash
I have a Hondata Pro flash installed in my RDX. Yes I do love it. Would be nice to see a Dyno test of Hondata and K tuner to see how they compare. We can all talk about numbers but let’s see what the Dyno numbers say.
#238

Running the base map for K&N SRI. More fun to drive. When I get the chance, I'll plug in my Bluedriver or Flashpro and get the IATs with the K&N SRI. Sadly, I don't have IATs with the stock airbox.
#239
Can you tune the Hondata tunes for the 2007-2009 on a 2011? Flashpro contains basemaps with the K&N SRI, and another for the 600CC injectors for the 2007-2009. 2011 only has the "regular" remap listed.
I'd like to get the SRI and flaspro and use the 07' tune on a 11' - if it is safe.
Also does leaning out the A/F mixture actually make noticeable difference on highway driving (steady state).
