Hondata Reflash

[elitee]

I remember reading somewhere that they were going to release one for the k24a3

Anyone heard anything about it..

[snYpz]

Nope. You might be talking about Jtune whom were planning to send our k24a3 ecu's to hondata to reflash. They are not very reliable, and some people havent had good experiences with them.
The other option is to buy a tsx ecu and get it reflashed. Take ecu to honda dealer to calibrate with immoboliser.

[Fredoops]

*revive*

Had anyone actually installed a reflashed CL9 USDM Acura TSX Ecu into their euro and have the immobilized re calibrated by Honda dealer?

I'm eager to tune mv Euro byt I'm not spending $1200 for a tune.

[MingZai]

^ fredoops I think great minds think alike lol cause I was reading about that the other day and I think it's possible but really depends on the Honda dealer and whether they will be willing to do it.

Look into a Haltech Interceptor.Approx.$1300 inc.dyno tune.

[Fredoops]

Lol I'm thinking under $500 lol

A TSX ecu can be brought for like $50-100 bucks, Hondata is 400 odd.

[MingZai]

Yeah so noones done it on OZHONDA?

See my post in this thread http://www.ozhonda.com/forum/showthread.php?150902-CL9-Jtune-Extreme-Package

I'm going to try to get the part number for my 2003 CL9, I have a hunch that the very early ECUs are the same... Then they branch out from 2005 onwards

[marquee]

at your request mate.... 2003 - 37820 RBB q01

[Fredoops]

Is that automatic or manual?

[marquee]

manual the auto is the same except q51 at the end instead of q01

[Fredoops]

Imma be the guinea pig and investigate this once and for all.

Ok, this is what I'm going to do:
1. Find out EUDM and AUDM ECU part numbers
2. Find out the Icelandic guy who was running K24A2 ECU (Acura tsx) on the K24A3 (European accord), how he went (he speaks english, theres a few russians who run TSX ECU on their accord, but communication may be a problem).
3. Find out any difference of ECU between EUDM/AUDM/USDM, both hardware and software wise (I suspect the EUDM and AUDM are exactly the same both hard and software)
4. Do an risk analysis on the differences between the 3 and the possible impact of running USDM TSX ECU on the CL9 Accord Euro
5. Get hold of a USDM TSX ECU for the 2003/04 model (37820-RBB-A54), plug it into my 2003 CL9 Auto, run a few days and see if there is any problems.
6. If Step 5 is succesful. Reflash the TSX ecu with Hondata.... PROFIT.

[marquee]

hmmm do it quick lol...just remember you need to go to the dealer to get immobiliser done.

if you have a good experiance i will be doing it. but just a question

shipping it hear testing it shipping it back to the states then shipping it back nearly cost of hondata.

should just get it flashed while its there wont be that much more expensive.

[Fredoops]

$1250 for a mild tune with Jtunes.

$299 USD for a Hondata Reflash in the states.
$250 USD for a 37820-RBB-A54 ECU from the States Shipped.
Allow $100 for Immobilizer re-programming (takes 15 min MAX)

The difference can buy me a high flow cat. And I have 2 ECUs at hand, I can return to stock if needed.

Besides, if it does work... Some of the Honda ECU (if not all of them) are Chinese made... There's nothing stopping me from getting 500 of them at $20 bucks each, have them all reflashed en-masse and flood the market just for lols.


Ps... Just spoke with a cousin... Ecu reflash tool is like $100 bucks (rffin thing is pretty much universal).. An immobilizer key calculator is like $50..

Fuuuuuu I should open a garage lol.

[MingZai]

haha fredoops I'll be following you :p

[y.vtech]

I just ordered a hondata reflash yesterday. Are you guys saying its not going to work with my ecu..

[Fredoops]

Hondata USA kept on saying they don't support AUDM ECU... So I dunno.

[y.vtech]

F**K. I'm going to try cancel and get headers

[Fredoops]

F**K. I'm going to try cancel and get headers
Ask them, given them the ecu part number and they tell you if it's supported (probably not)... However, it doesn't mean it can't be done...

[MingZai]

Just buy the USDM ecu y.vtech and then try what the iceland guy did or wherever his from :p

[Phorist]

watching eagerly.... keep us updated

[h1coupe]

I am the Icelandic guy that did this on my 06 Type-S.

I took my orginal ecu with me when I visited Sema back in 2006 and handed it to Doug@Hondata and had them check if he could flash it for me. The stock ecu took a crap and had to be replaced(can not confirm that it was cause of euro ecu cause some tsx ecu´s have done the same seems to be some percent just burns when trying to reflash) so Doug took a stock 2006 TSX ecu (RBB-A04 & A05 either one I have the number somewhere) and did the flash on it and I took it home with me at the end of the USA visit.
I installed it and got the immobiliser light(can be switched off by just unplugging the immobiliser, I did that for some time) then I had the Honda dealership flash the key to the ecu so that light went away.

On the other hand I had 3 check engine lights.
> po498 no definition found. (is for a purge valve according to Doug)
> po453 powertrain: fuel tank pressure sensor circuit high voltage.
> po128 powertrain: coolant thermostat.

I contacted Doug again and he told me to send him the ecu again, which I did and he switched off the codes.
I installed it again and everything went smooth and no lights at all.
Car felt awesome and I consider hondata to be 1 of 3 best mods for the euro, the other beeing a rear sway bar and changing gear ratios(either 1st gear and final drive from tsx or full type-R ratios set).

Dyno tuned the car with K&N CAI, ebay header and reflash and I got 212hp(183whp)can´t remember torque but it was something like 240+NM(170.5whp@6770rpm and 224.7NM max@4300rpm dynoed before with just intake and header), but max hp wasn´t the best thing about the flash but midrange around 5500rpm was up something like 30whp and the power curve was much more "user friendly" .

Why not invest in a Hondata Kpro and run a dual harness?

And what is 1250 for a mild tune? A tune is a tune, it should be tune correctly

[h1coupe]

a mild tune does not mean it´s tuned incorrectly, I believe a mild tune is for a car that is mildly tuned I/H/E something like that.

Kpro/dual harness = no VSA, no cruise.

[marquee]

Kpro/dual harness = no VSA, no cruise.

I was thinking today (it hurt my head) and i came to the conclusion all could not be lost.

KPRO uses the DC5R ecu right?

What if it was possible to use the DC5R cruise control unit and connect to the KPRO it may cost a bit but could be done I think

[Fredoops]

Likewise, I hate thinking logically. Dc5r don't have hill ascent control sensor thingy.

[marquee]

just been doing loads of research ecu is the same just immobiliser not working.... in this case im going to buy the ECU and supercharge my car. The CT supercharge comes with the a reflash so might buy a stock TSX ECU and ensure it works then save for the supercharge :).

No need to KPRO

[Fredoops]

Imma get a ECU reflasher... See if I can override any CEL's that come up

GHETTO Tune FTW

ahwell not to fused. just poped the ecu diff question on tsx club. and got.


K24a2 differs from k24a3 only EVAP system If you use K24a2 Ecu you get Check Engine - but ECU doesn't go in limp mode. It's only one issue - check engine light, all other works without problems.
I was using Hondata K24a2 reflashed ECU in mine EUDM Honda Accord Euro CL9, great gains Now time for K-tuned Dual K-Pro setup. Question if there is differencies between AUDM and EUDM ? I thinks that shouldn't be.

Is there any diff between EUDM and AUDM i think they maybe

[Fredoops]

Probably not. Since EVAP is pretty much the only main difference betwwe AUDM and USDM ECU (apart from 4 sensor VSA in the TSX compared to 2 sensor -front only VSA in the EURO).

This is looking better and better lol!

DAmn spare parts, still trying to get hold of a 2004 TSX ecu for auto.

[marquee]

man theres loads of them on car-part.com going for about 2-300 just might b a bit hard getting them to ship it to aus

not really a part u will find on forums no demand for them

[Fredoops]

There's loads of different part numbers, I need the RBBA51

[Fredoops]

*update* the plan hit a bit of a snag.

Did some more research, the EUDM accord is basically the same as the AUDM, except the interior. So whatever CELs the EUDM cars get when running the TSX Ecu we'll most likely get as well.

Now here's the bad news... You'll most likely get a CEL for the EVAP purge valve (OBD2: P0498). And one for the fuel tank pressure reader (OBD2: P0453).
Now, I believe they can obviously be turned off.... But then it raises a safety concern...

The moment I hear purge valve and oil vapor pressure... I think KABOOM! Lol

Or am I over worrying about the EVAP settings?

[MingZai]

Fredoops hows this going??? I really am looking to do this!!

[Fredoops]

Can't find a RBB-54 from a dealer in US that ships overseas.

Well I did find one last week buy it's hot a layer of rust on it, I ain't buying that...

[MingZai]

what's a RBB-54 ?? Maybe I can try help you.

[marquee]

It's the tsx ecu

[MingZai]

why can't he just buy one through Hondata?

EDIT: NVM reread the website and found out you can't.

[marquee]

Doubt they would have one as its the factory tsx ecu but the have a second hand one so hard to call though there timezone is wack I tried setting an alarm but it didn't work to well might do it this Tuesday morning I'm waking up early if I remember

[MingZai]

tell me how it goes? Your in Melbourne too so I think it would be good to get this sorted out once and for all. But I can tell you now I am in for this and planning to get this before anything else...

[Fredoops]

I'm too broke atm to mess with the ECU sorry..

What you might be able to do is get in touch with heeltoe, have the 2nd hand EcU sent to heeltoe and have Marcus send it to Hondata... Just tell him to have Hondata remove the CEL codes I found above....

[boleh]

Just a thought... if you're after performance why not sell the CL9 auto and buy a CL9 manual?

The 5-spd autobox is the CL9's achilles heels

[MingZai]

Me? Well if your talking to me I'm going to do all the non/engine mods first and see if I still wanna go ahead with modding the Euro. If I do... then I might do an engine swap with a K24a3/K20 Hybrid + the Manual Gearbox

[marquee]

worth just selling your euro then buying gearbox seperatly they are super expensive and only place you may find one is in the wreckers second hand hand. not much point pouring money in an automatic its not just the gearbox you need to buy but a shifter setup pedals ecu and probably more. its not easy to do a swap in our cars

[MingZai]

Yeah but I know my Euro hasn't been thrashed haha hmmm it's a luxury auto... gearbox is $1500 quoted mmmm shifter pedals won't be a problem and ecu i'll be getting it from hondata reflash :D

[boleh]

how much would be the labour charges to convert auto > manual?

[Fredoops]

Crap loads... Might as well sell your auto and get a manual...

Interiors different, different ecu, different engine torque damper etc.

[MingZai]

labour charge will be zero probably ... mate said he can do it so the both of us will be working on it lol

[marquee]

Don't doubt your mate can do it but why bother how many euros have been thrashed by it from an old person there cheap and don't thrash their cars

[MingZai]

CEL for the EVAP purge valve (OBD2: P0498). And one for the fuel tank pressure reader (OBD2: P0453) what do you mean by that fredoops??? is it only cause we are missing sensors?

[Fredoops]

Not sure if it's missing sensors or different sensor config. I don't think they are relevant to the safety of the vehicle.

Having said that, I wouldnt mind an expert like aarong to elaborate it further if he can.

Well as many people know we have been conducting testing, tuning and product design for an Australia Hondata Euro Flash update for the Australian Domestic Market for some time now.



What we know so far : -

...

The Australia Honda Accord Euro Does not have Rear wheel Traction Sensors for VSA system.


The Australia Honda Accord Euro Does not have a Vtec Oil pressure switch - circuit high voltage.


The Australia Honda Accord Euro has Australia specific EVAP FTP and EVAP CVS sensors settings.

....

Thats probably what.

More info on the TSX sensors.

http://www.obd-codes.com/p0453
info on the Code itself


Edit:
you know what, you can probably "TSX-ise" your car to get rid of those CELs without reflashing to remove the codes.
just replace the AUDM sensors with USDM sensors:

[Fredoops]

Before you ask... No, I haven't got a TSX Ecu to reflash. No$$ for it ATM.

What I did find is this post about price of jtune on the Hondata page.

http://www.hondata.com/forum/viewtopic.php?f=11&t=13004

[marquee]

There website has shown that price for a while now

[npcan2]

Look into a Haltech Interceptor.Approx.$1300 inc.dyno tune.

I agree with tony1234, I had the haltech interceptor on my car and it was fantastic!
Even when the car was stock, torque increases were great across the range. When I had intake, headers and exhaust, the car pulled 143.9kw atw. I got more power from the tune than I did from all the bolt-on's combined without a tune.

[MingZai]

still prefer hondata :p

[npcan2]

still prefer hondata :p

For any Forced induction or Built NA motor, hondata is the way to go! But for any 'light' build with bolt-ons, a piggyback is more than enough. Even when my car was completely stock with just my haltech I had heaps more torque and power. Just my 2c, only talking from what I know and have done. :)

[Fredoops]

Hondata is designed for light builds, Hondata themselves market it as designed for bolt-on and mild mods. comptech S/C kit gets a different hondata tune Iirc than the normal reflash

Advantage of Hondata is that it lowers VTEC engagement AND changes drive by wire settings, at all throttle levels, which makes it more comprehensive than a piggyback.

[npcan2]

Sorry, I meant Hondata k-pro, not the reflash for bigger builds.

I personally don't like how the reflash is preset and isn't really tuning. It's a one size fits all solution. Im not sure you can go back and 'fine tune' a reflash.

Good discussion btw. :)

[shmivic]

Wow this thread hurts my head to read.

[marquee]

Yer I agree with fred the flash is better but kpro is supreme in my opinion.

[marquee]

Mingzai did you get this yet

[MingZai]

in negotiation atm... anyone else interested?

What you mean negotiations

Meh im not interested anyway

haha lol keen on getting an ecu, thought this thread may have made it clear what to get, am even more confused now, have never seen so many meaningless numbers and letters.. i guess ill just put it off and do other stuff haha

Jist of the thread. Can do hondata flash but will get check enging light. Or can pay 1200+ for jtune flash.

But flashpro is coming out and so is heeltoes thing so no need to worry about reflash

You can get rid of hondata engung light by replacing a purge and fuel tank sensor with USDM parts.

Else wait for FlashPro or Heeltoe

[adis]

which one do i go for? :S

Approx cost of each unit+tune? Where do i get it? Whos able to tune it?

Sooo many questions :)

so you're saying just to wait it off a little bit and there will be a tune/reflash that is compatible with an 03 cl9 in australia?

[marquee]

Wait untill jan should now more

[ajphillips92]

too easy, looks like ill buy myself headers for christmas then get a tune early next year yay
