I know. Besides, it is not confirmed that CT SC will fit 05 auto. It doesnt fit 06 auto eventho there is reflash available for 06 auto so I will keep my 04 ECU in closet in case I will have spare cents for a SC Or if I will decide to get KPRO and then abandon that Idea. No $$$ for those things yet

godfather2

if you have an 04 ecu, the s/c should work fine on your 05

valeratj

I know and thats 1 of the reasons why I bought it- option of SC . Do u know if anyone had any problems with running SC on AT models ?

godfather2

^ our auto tranny seems to hold up pretty well to the s/c. i wouldn't be too scared to go ahead and take the plunge.

now, if you plan on running a high boost pulley, water/meth injection, or nos simultaneously then i'd probably reconsider

as colts has pointed out, no etd on the market fits the auto/sc configuration. you could always get engine mounts instead

valeratj

Nah, 7 PSI will break tranny most likely. What do u mean by "etd" ? and why would I need engine mounts ?

MMsTSX

an ETD is an Engine Torque Damper.

and nobody has tried the FEEL'S one yet, so nobody can
say that it doesn't work.
it is designed different from all the rest and worth a try.

you would want new mounts because you would want stiffer ones.

and nobody knows what will break out tranny until they do it.
I've yet to read of it's threshold. so it's all just guessing on that account.

godfather2

etd helps put power to the ground by reducing wheel hop/spin. stiffer engine mounts do the same thing basically (only better), but they tend to create more in-cabin vibration than etd's

carmagnut

Does the ETD come with the CT SC kit or has to be a optional side purchase?

godfather2

it's totally optional, not necessary at all

back on topic:

how many of you out there waiting for the reflash are now considering kpro instead?

1slwTSX

So is it due to emission issues thats why we cant reflash the 05 auto and/or add the supercharger? Excuse my noobness, im new to the TSX scene. I know 05-06 RSX guys cant do a reflash also unless they get a 02-04 ecu and throttle body.

valeratj

I am really thinking. I have 04 ECU and I could get SC... and/or K-pro, but I am a poor college student and cant really afford those PRICY things at the moment. So I guess I will just stick with the reflash

Tsx536

Saw a post on the Hondata forum confirming the 05 AT reflash:
http://www.hondata.com/forum/viewtopic.php?t=6988

congrats guys!

FYI, the 04 and 05 Auto's are identical mechanical wise. So a SC kit for the 04 would fit on an 05. The only thing keeping Comptech from selling it in the past was that they couldn't put the SC reflash on the 05 ECU. It sounds like that is solved now though.

1slwTSX

That's good news. Been waiting for this to come out. Hopefully someone can get an ETA on this reflash.

godfather2

anybody checked on this lately?

or is every1 just going to opt for the kpro?

valeratj

I checked yesterday or 2 days ago. Nothing new, really. I am waiting for reflash bc K-pro would only be an option if I was going for some serious upgrades (turbo/cams) However, there is still a possibility that I will change my mind

CarbonGray Earl

I still want it. I'm only going bolt-ons, so this will be all I need.

valeratj

Same here...

xenonhid

^^ I'm a big fan of mods that retain OEM reliability and performance.

This reflash fits my needs for increased performance with OEM reliability.

valeratj

^ I am 101% with u.

godfather2

anyone with the 05 reflash yet?

CarbonGray Earl

Not me yet. Waiting til after tax season.

akio015

Is there actually a HONDATA reflash for the '05 AT??? Can anyone confirm this????

valeratj

Yes there is. Go to Hondata's webpage. They added in on Jan 9 this year.

Impulse05

So with an A/T '05 tsx and the A/T '05 reflash would u still need to buy a key and get the immobilizer synced? or is that only for an '04 ECU in an '05 tsx?

godfather2

if it's your original 05 ecu that you are sending to hondata, then no immobilizer and key are needed

Tsx536

As an 05 owner, you will not need to buy anything extra. Just ship them your ECU, immobolizer, and a key.

CarbonGray Earl

update: I paid my taxes.....and as of today, my TSX is Hondatafied.

Such an awesome mod.

northbridge

care to give it a review?
not that there arent enough impressions of the reflash floating around...

CarbonGray Earl

Sure, but I haven't gotten to really "test" it. Most of the driving I've done is in LA, in some light traffic, so the only time I've really gotten to hit it hard is in large gaps of traffic. Kept it under 80 most of the time.

My current mods for power are: CT-engineering I/H, 17 lbs wheels, TB spacer.

My first impression? There was no change in idle, and the engine note didn't change at all. No extra vibrations, no lumpy cam, no exhaust change, nothing. As far as I can tell, its was just like before. Great, because I don't need this car to feel like its changed its normal operation.

But I can tell, with a little bigger step on the gas, things have changed. Power comes on quick, there is no pre-vtec dip. I've been driving my TSX for a long time (80k miles) and that's the weirdest thing to get used to. You don't pay a price to get into the upper rev range (6k+). And crossing into vtec at 5k feel great, but those looking for a audible reward will be disappointed. There is a definite power increase (or it might be just me anticipating a drop) but its just not easily discernable because its a smooth increase. Some nice N/A style power - the power is not stepped like a vtec vehicle from the 90s or a turbo, etc.

Since my pre-reflash car is fresh in my mind, I can tell that the car is well ahead of where it once was. It gets into the powerband quicker than I currently anticipate, so I will have to relearn everything. I was pretty good about anticipating upshifts, but with the changed rev limiter, I'll have to have a couple of runs to get used to it again.

Overall, its a great mod. It not only fills in the power dips, but it opens up everything as well. I think its the best mod I have gotten. Definitely up there on the bang for the buck, especially if you already have I/H.

Oh, and before I forget, I got it for the GB price wong05tsx put together. Shawn was great too, did it quick and honored the GB price even though I wasn't with the large group. Great mod, great price.

I guess I am the only one with auto transmission who is saving up for K-pro....

I went through a tank of gas in 3 hours =X. I guess I was having a little too much fun haha...

But in regards to gas mileage, since Earl didn't cover it -
On my drive down to Socal to get the reflash, I averaged 29.6 on the Trip Computer -- going around 80-90 the whole way, with a few spirited spurts. On the drive back up north, I averaged 29.4, so I think it's safe to say there is no effect on the mpg. This was a ~400 mile trip each way by the way, so the numbers should be pretty accurate.

Thanks for everyone who participated in the GB and making it possible

Here's the dyno for those interested, only performance mods is I/E..... though I just bought Dayta's CT header since I'm itching for more power now

Before reflash:

After reflash:

valeratj

Tell me about it.... its sooooooooooooo addictive....

northbridge

nope, i am also. hopefully soon, my car will be very similar to the car hondata has right now. Hytech full exhaust, k-pro and supercharger. I just cant decide in which order i should get the last two...

great reviews of the reflash above also.

k-pro first, SC next imo.

DAYTA

Personally, I would go with the S/C first, then K-Pro down the road.

If you go K-Pro first, you'll have to get it tuned which runs ~$1k. Then, once you add the S/C, you'll have to get it tuned again, effectively doubling your tuning costs. The stock CT S/C kit will function just fine with your car as it is now, and IMO will most likely net better gains then going K-Pro only. Tsx536 has been running his S/C setup @ 5psi for 50k+ miles already.

However, once you add K-Pro and increase the boost, there's a strong possibility that you'll also have to reinforce your transmission to safely handle the additional power (upgraded torque converter, clutch pack, etc).

northbridge

i thought there was a k-pro basemap hondata did with the hytech exhaust and injen CAI? i didnt know i had to tune again.... if thats the case then ill def get the SC first.

For power i think i want to stay in the 270 range... More specifically i want to run the most power i can on the stock transmission.

valeratj

northbridge, if u want 270WHP, u dont even need SC. Hytech will get u there IMO. Also, I wouldnt risk putting more than 230-40 WHP on stock auto tranny. I will go bolt-ons for now, then swap tranny far down the road and then get FI. By that time there will HAVE TO be a turbo kit

DAYTA

I believe Doug's Hytech tune was also done with a machined VTC so you would have to modify that as well to use his map. I would confirm that with him, though.

Horsepower figures don't determine how much power a drivetrain/transmission can handle - torque figures do. At ~270whp, you should be around 200-210wtq. Since no one with an AT transmission has hit those output numbers yet, it's difficult to determine if upgrading components will be necessary. I can say that on my MT, I ran into some minor clutch slippage issues at 276whp/211wtq (only 28k miles on the car).

valeratj

Exactly. That is why I want cams instead of SC

northbridge

Noted.

more research to be done... thanks Dayta, very helpful post.
