Hello guys,

I tried searching around but couldn't find any real information about the effect of the Hondata reflash on our 0-60 times. A buddy of mine just got his A4 chipped (through APR for those that are familiar) and it has made a hell of a difference.

Now, I don't expect nearly the same gains (A4s come with turbos) but I was wondering where I would stand in the 0-60mph times off the line.

Thanks!

A couple tenths at best. You're only gaining power in the middle of the power band and not substantially affecting the top end horsepower.

Have you checked out Hondata website?

http://www.hondata.com/reflash_tsx_06.html

It shows little gains in the low RPM range and moderate gains (25 lbs of tq max) in the mid-high RPM range (4800-6000 RPMs). You would have faster acceleration from 40-80 mph range compared to a 5AT without the reflash.

But for everyday driving? Its very, very sweet.

I KNEW IT! AT's are faster.

Faster than what? A reflashed 5AT TSX is only faster than a non-reflashed 5AT TSX, if everything else is equal.

Hondata can reflash RBB-A61, the newest 2006 TSX ECUs.


It turns out that, at production years end for the 2006 TSXs, Honda was installing a newer generation of ECU’s.


I sent the ECU from my 2006 Acura TSX 5AT to Hondata on 15 Dec 2006.

I love my new TSX; but I was disappointed in the power drop between 5000 and 6000 RPM.

I had done a great deal of research, and the literature and user reports all pointed to Hondata’s reflash of the ECU as a great investment.


There was one slight glitch.

After removing and sending the ECU, immobilizer, and a key expedited by a dealer directly to Hondata, I noticed that, among all the myriad of numbers I had copied off the ECU, was the number “37820-RBB-A61”. My memory flashed on the statement from Hondata’s website that said:

“Who can use this upgrade? Any 06 TSX K24A2 TSX with the ECU part numbers (covers all current 06 ECU part numbers) :
RBB-A04 - 06 TSX
RBB-A59 - 06 TSX Auto”

Panic City!!! I e-mailed Hondata and asked if this number ECU would present a problem. Their response was “ It may be some time before we can reflash this ECU.” More panic!!!!

I called Hondata the next morning. I was initially disappointed to hear that it could be “days or weeks” before my ECU would be done (and thus days or weeks that I’d be without my wonderful new car). I was advised to call back in 2 hours, however, to talk to Doug MacMillan. I called back; and Mr. MacMillan reassured me with his wonderful New Zealander accent that, although they had been temporarily surprised by this new generation of ECU, they had been successful in working out the program, and that they would have it done and off to me in overnight express that evening.

The ECU arrived 21 Dec. I reinstalled it and found the performance just as advertised.

Now any of you 06 ( and possibly new 07) TSX owners with ECUs having this new generation model number can know that Hondata is ready to serve you.

I highly recommend these folks. Their customer service is efficient and pleasant, and the results of the reflash are super.

For those who are curious, there is no change in 0-60 ET in full auto in fact there may be a 0.1 or 0.2 sec reduction. With auto-stick however, shifting from 1st to 2nd at 7200 RPM there is a 0.1-0.2 sec reduction. This is as measured with a simple stop watch by the driver. I did 10 runs before and 10 runs after reflash. Before, average 8.3 sec in auto, 7.94 auto-stick. After average 8.5 sec auto, 7.79 auto-stick. So, if your hoping for a change in raw acceleration off the line, that’s not what this mod will provide.

The main difference is the smoothed torque and HP curve. This, combined with the change in the Vtec point to 5000RPM, makes the power much more usable at all RPMs. Thus, there are no disappointments when you stomp on it in AT to maneuver in traffic. The fun of driving in the back country in Auto-stick is greatly enhanced. The car feels and sounds like a smoothly running high RPM vehicle. It’s a joy to be going 70 in 5th at 2400rpm as one approaches a 30 mph curve, downshift to 3rd , jump to 6000RPM, let the engine slow you to 60, and accelerate back out of the curve from 5000rpm with full power. Also, the 40 mph-80mph pass-a-car take off is notably improved. Basically, the car is just a lot more fun to drive and performs like it should have in the first place.

+1 for Hondata. Possibly the best investment I made in my TSX. Its great to hear their service is still up there and there were no problems with the new ECUs.

Even the 04 ecu swap i would say is an investment. I ahve to say hitting vtec everyday is such a blast with hondata.

He speaks the truth though. We ARE faster..

When the hell are they going to have the reflash for the 2005 5AT TSX's, I've been waiting for a long time.

There isn't a reflash becasue the ecu fails the smog test when the vin number pops up. Something about the vin number is changed when hondata relfashed it. So they didn't release any 05 AT.

You can do an ecu swap with an 04AT.

mav3556

damn this sucks, how about an 06?

jlukja

The re-flash is available for both the 06AT and 06MT. In fact, its available for all the 04/05/06 models except for the 05AT. See here: https://acurazine.com/forums/showthr...hlight=hondata

mav3556

I called Hondata and e-mailed them but they won't give any kind of striaght answer to why they can't create a reflash for the 2005 TSX 5AT.

how's the mileage affected by the reflash?

Reach

Mileage is not effected by the reflash.

raheel616

man i would do hondata but i still have hopes of kpro, although my biggest problem is that i need my car everyday

khmy2nr

Reflash for 05 AT is not needed. The car is fast enough already

markm929

Just to clarify...mileage as in odometer reading, or MPG? I was just a little confused.

jwood_06TSX

your mileage will most likely go down cause you'll be in vtec ALL the time once you get hondata

jlukja

"mileage" as in fuel economy (MPG)

markm929

Is it a significant drop? or just like 2-3 mpg?

jlukja

There is NO drop in fuel economy due to the reflash. You may drive your car more aggressively (because of how it responds) and your mileage may drop due to this change in driving style. If you do not change the way you drive you will not notice any change in fuel economy.

I dont know why but your avatar picture got me to laugh. maybe its the way he is holding that thing?

will the reflash void ne type of warrenty? i would love to get it for my 06 mt.....but i dont want to void certin warrenties.

daicacharco

nope ..

waTSX

Flash away dude. Unless you tell someone, nobody is going to know.

jlukja

All your hondata reflash questions are answered somewhere in this thread:
https://acurazine.com/forums/showthread.php?t=21119
I think every reflash related question has been asked and answered in there somewhere. Does it void the warranty? It depends on what you break. The dealer has to prove that the reflash led directly to a failure. So, for example, if your A/C compressor goes out then the dealer has to fix it under warranty. If you bend a piston rod and the ECU recorded an rpm of 7550 then they will not fix it under warranty (reflash raises the redline from 7300 to 7600).
