around what rpm would you start to hear/feel your vtec. i just got my tsx about two weeks ago and i only pushed it once but didnt hear the vtec or felt a difference. Is there something wrong or is it just like that?

04 tsx 6spd w/ navi

Approximately 6000 rpm or 6500 rpm the vtec will kick in..... be ware it is not like a turbo engine and you will not have the back pulling kindda feeling as strong as a car w/ a turbo engine.

...also, don't expect it to be there on startup either. You're engine has to be warmed up since this system works on oil pressure.

Yea what they said.... I love it when it does kick in and I hear it.

mrgold35

Since your TSX is used, is there a chance there are some mods on your car that have increased HP and smooth out the iVTEC kick you would feel on a stock TSX (intake, header, cat, exhaust, pulley, Hondata)?

Hondata would be the big one that would affect the i-VTEC at 6,000 rpm; but in a very good way.

davidspalding

I know there have been previous discussion of this ... try the SEARCH, though with patience, you can only submit every 60 secs. For my part, it feels like a "second wind" when accelerating in-gear up to redline. Not something I do more than once or twice a month.

I have owned an 05 and now a 07....., and i have definetly noticed that the 06's through 08' show more of a pronounced kick into vtec......, I could barely notice it on my 05'..... It is like night and day (for me at least)

jwood_06TSX

^^ what he said. I owned a 04 and then upgraded to an 06 due to an accident and the vtec kick at 6100 RPM's was MUCH more profound in the 06. Its like a mini little turbo boost especially on the highway when you hit it in third gear and go past some one....its a nice little boost.

If your doesn't kick a little bit at 6100 RPM's, then you might have gotten lucky with hondata already being in your car which means you'll feel more pull around 4850 PRM's but it won't be significant, just smooth!

csun2004

^ I agree in 06+ the iVTEC kicks at lower RPMs. it is a great feeling the car sounds more agressive and you see yourself flying by other cars.
u had the car for 2 weeks and you only pushed it once! go ahead and put your TSX to the test it wont disapoint you.

I don’t' think anyone is stupid enough to "leave" the Hondata unit in the car when they could sell it on the boards to interested car freaks. People will sell used brake pads and here we have some guy that left the Hondata in the car ???? Yeah right

I think CL9alltheway doesn't know what to expect or hear when VTEC is about to kick in . I can barely tell in my AT 05 TSX even in Manual mode, infact I'd almost think it's not kicking in, compared to my H22A from the Prelude.

It's a little ridiculous to have it kick in so high up in the RPM band, because just as it kicks in BAM you have to shift gears.

Just make sure your oil is topped up and the car is warm before you go for some WOT runs, you'll get use to "almost" hearing and "almost" feeling VTEC kick in.

hondata is definitely where it's at. i feel on a stock tsx the vtech doesn't come in to play soon enough. there's so little time to be in vtech before redline that it's almost useless.

especially with the auto, in SS mode, you've got to shift up right as you hit vtech or else you bounce off the rev limiter.

i've got the cash for hondata, but i need a car and haven't turned 25 yet (and therefore can't rent for the few days my car would be ECU-less)

jwood_06TSX

Enterprise will rent you a car as long as your 21 but they will only give you the lowest model and maybe charge you slightly higher rate, i think it was like $10 a day more when i did it (i was 22), which is all you need. Check them out though.

I agree with you though about being in SS mode as soon as it hits if your not ready to shift quickly, you'll bounce it. I have done it twice....OOPS! If you shift just about immediately when it hits 7k rpms, it will shift right at and around the 7200-7300 area it suppose to

ruffellprefley

thanks for the heads-up. i'll look into it

CL9alltheway

ummm i guess thats answer my question im not going to hear or really feel too much. that sucks tho cause i use to drive a civic w/ vtec and even with a single cam i would hear and feel the difference. So i guess i have to work on getting bolt ons and reflash to feel some power. neways tho if i get comptech headers do yall think ill need to change out the exhaust system? whats stock piping on a tsx 2? inch??

moda_way

The point is iVTEC took that jump away by advancing/retarding the cam up to the VTEC point so there is a smooth transition. Remember, you're driving a luxury sport sedan, not a Civic (no offense to the previous owned Civic).

With all my performance mods, I can tell its there.

dlee74

Do you guys warm up your i-vtech engines in the cold mornings before you drive off? Is it required?

dj Dozhe

I've always heard it's good policy to warm up an engine before you put more stress than necessary on it. So I usually follow the policy of trying not to go higher than 4-5K before the engine is warmed up, and certainly not in vtec range.

(06 non-hondatified 6MT)

Superb0o

I have the ETD, when my VTEC kicks in I feel/hear the all around me now

TommySalami

It's REAL noticable with my Injen intake

EuRTSX

Like others said, warm up your engine first.

6k+ in 06's

Roffles

If this is some sort of a joke, just ignore me....but Hondata is an ECU tune. You can't bring Hondata with you and sell it on ebay when you ditch your car. The only way to un-hondata a TSX is to get the ecu reflashed at the dealership or to replace the ECU. The first option is pointless and the second option costs more than a Hondata tune.

I read a random thread a while back that may indicate Vtec doesn't function correctly in some cars because of a busted sensor or mechanical unit (can't remember exactly) that tells VTEC the oil pressure is at the correct level to engage.

I've bounced almost enought times to where I can't count. . The high rpm's creep up so fast..

TommySalami

Yeah, but they could swap their hondatafied ecu for a non-reflashed one, and some money in return.

dlee74

What is ETD? Is that a part you add to your engine? That is cool to hear more of the Vtec sound when this part is added.

CL9alltheway

okay i know this has nothing to do w/ vtec but since i have everyones attention...what kind of bulbs come stock on the tsx? i heard it was 6k bulbs..dont know too much about hid, so i wanted to know if i wanted to cause i buy 8k bulbs would they work?

Mokos23

i-vtec i feel for me kicks in around 6rpms, but of course not a speed demon by any means. also, of course when the vtec kicks in i see it start to consume more gas, oh well, common sense.

TommySalami

Do a search. It's on here.

davidspalding

Since you already know it's off-topic, I'm sure you won't mind if nobody answers you. Nyeah! Post NEW THREAD with NEW QUESTION, lazy bones.

Tumby

I guess it should... but you will be loosing the brightness as it will becoming too much blue in the light..

davidspalding

Please, no encouragement. New questions belong in new threads.

edit: who hijacks their own thread?

ILoveMyHonda

I would definately say that even adding just an intake makes the iVTEC sound more evident. I can feel it kick in at around 6k. (6MT)

Since your car is pre-owned try removing the resonator (if the prev. owner hasn't already), it helps in the "sound" dept. too.

The OP apparently does.

CL9alltheway

i know that CAI is more popular here? but would i hear it is i just went w/ short ram?

davidspalding

RE: hijack --> Well, it hurts people searching for information and answers when discussions are hidden in threads on other topics. Like an ongoing discussion of Jedi ethics in a thread titled "Star Fleet officer behavior." Someone searching for "HID bulbs" will not think a thread titled "vtec" will have any useful information.

CL9alltheway, you might want to browse/post in the Performance Mods and Parts forum for previous discussions of air cleaner mods and such. I know I've read a LOT about the Hondata reflash and K&N Typhoon intake there.

I also really think you ought drive the car around for several weeks before deciding that you absolutely, positively have GOT to modify the powerplant. It's a pretty good car, stock. That's why a lot of us bought it.

Waitaminute ... who died and made me a mod?
