Take a good look at the modifications we made to the VTC mechanism. If you have a TSX you are going to need these changes. Although you could probably purchase and bolt on an RSX VTC mechanism for 50 degrees travel, there is less valve to piston clearance on the TSX pistons. Our measurements suggest 45 degrees maximum cam movement is much safer. Allowing the full 50 degrees movement leads to a greater risk of valve to piston contact should you accidentally mis-shift and over-rev"
I'd also say that you do sound a bit spoiled with your access to various modified cars and as a result probably had very high expectations.. You keep saying "don't flame me for comparing the M3 and M5 to the TSX" but it is in fact what you keep doing... Those engines are noticably different from the TSX engine and the reflashes are different as well. Most, if not all, of those reflashes (1.8T, M3, M5) add HP and as many have pointed out the Hondata does not... I know for a fact that the VW/Audi 1.8T is VERY crippled in the stock config and reflashing can open up a ton of HP in the curve.... (My last car was a 2001 Turbo Jetta with the 150HP 1.8T... in 2002 they bumped it to 180, but people can hit over 200 with a reflash and lite modding)....
Also, if you go out for a run in your boyfriends modified M3 and then hop into the TSX you may be "tainting" the experience a bit as well...

I am coming from a 1.8t Jetta and with just the ecu upgrade where there was a huge difference in power.
Now, I do not have the Hondata reflash because I have an 05. From what I have read it lowers the vtec and you will see some more performance from the vehicle.
You gotta realize our cars do not have a lot of torque so your not going to notice that "throw you back in your seat feeling." So if the reflash did lower the v-tech and did advance your torque and timing. So you got what was supposed to happen.
I guarantee that is you were to do a 0-60 or a 1/4 mile times and it will be faster. That would be the true test.

I'm all stock aside from Hondata and I noticed a nice increase in performance even below 5000rpm, not to mention its great when shifting at 7600 since you don't fall off the vtec cam and stay above 5k.

WAS HONDATAFIED IN
my 2 pennies....... i'm hondarafied, with no header, but cai......i also did notice an increase in power, not a surge, but an increase...... the only thing i am thinkng is that another member here got reflashed and had a loss of power after 5000 rpm, while it isn't a widespread problem, it might be that a few certain tsx's ecu's are not acceptong the reflashes, maybe ones with a really late build date??? i don't know, just giving my opinion, i think a dyno should be had to verify the gain/or losses, and then go from there

i don't have the power below 5000 i don't have an increase in anything unless i redline the shit out of it. thats where my concern lies. ill know tommorrow whats up and i know a great dyno place. i just really thought i would experience everything everyone was talking about. i pulled out of the lot in my car and immediately got on the phone with my boyfriend and was like wtf theres nothing. kept driving it and there still is nothing. its just very dissapointing and a waste of money as of right now

Wonder if the third party is willing to do a dyno on behalf of Hondata, just to prove that the reflash was not simply a shift in VTEC threshold and raised RPM limit.
I do think Ontilt brings up a very good point. I imagine it would be hard to be objective when you are comparing to an M3.
Regardless, buyer beware!!!

cant really compare though. the ecu reflash on the 1.8 turbo increases psi and can add like 30 hp. Things arent as easy on a NA motor

You're not taking full advantage of the Hondata reflash BECAUSE YOU DON'T HAVE A HEADER.
As long as you don't have the header on, you will not feel as much of a power increase as the others who do have this mod. This is because Hondata designed their program with a CAI and header included.
It is pretty simple in fact. The reflash will add a more agressive fuel map to take into account that the CAI and header allow the engine to breathe better. If you only have a CAI but not a header, the engine can suck it easily, but cannot push the exhaust any faster than stock. If you give it the fuel map it would need in order to work well with CAI and header, but don't have it on your car, the result is that your fuel mixture is not good. The O2 sensors will know this and order the ECU to lean back down. Your upgrade is then cancelled.
No need to blame hondata. Get the right complementary equipment and it will work well.

I would wait for the header install before the dyno though. Please let us know how it goes.

Same here, I took out my TSX today and did a power run. Hell yeah I felt a difference, and now that I installed the CAI a few days ago, the car is ridiculously quicker that stock. I wonder if something could have happened and the reflash was not completely installed???

my worry is something got messed up with the reflash-not enough to mess up the v-tec and rev limit but enough to compromise the power i was expecting. I keep romping on the car hard, now making it up to 12 "power runs" and there might be a slight difference. Slight or maybe im just hoping so much im imagining things. Found a dyno that was only $80 for 3 runs. Will dyno now and after headers, if i still don't get anything, im driving the car off a cliff

Don't be discouraged. For me, the Reflash was totally worth it.
Your dyno run should tell. I would contact Hondata and let them know what is going on with your car.
Good Luck!!!!

I did and so did Action Tire. Hondata said to dyno the car and see whats up. Im going to attempt to do it by Wednesday but im going to upstate Ny for some quading and might not have time to dyno it. Then i start school next week and won't have any time to do anything. i really hope it will settle in. My guy at action did tell me a funny story about the 300C-all these guys got it chipped and immediately called and bitched about the lack of power from it. One month later they all shut their mouths when the computer settled and programmed your driving methods.

Another thing - what grade and brand of gasoline are you using? Is it possible that the quality of gas or the octane of the gas you are using isn't high enough thereby tripping the knock sensor and causing the engine to retard the timing?
If it can't be traced back to any of these types of issues, I'd say your butt dyno is off.
I remember back when I installed a chip/intake/exhaust on my twin turbo Z which added 70 wheel hp, I wasn't too impressed by the how much faster the car felt b/c the upgrades fattened up the torque curve and decreased the turbo lag. The car lost the stock slingshot power delivery feel.
I'm thinking it's possible that the Hondata upgrade, which smooths out the VTEC engagement and increases all around torque may take away some of the sensation of speed which was present w/ the stock power curve which had a sharper spike in torque/hp at the VTEC engagement point.

93 octane-the car is feeling better and better, i think, however, blowing a tire today (thank god my rim is fine) and the a/c clogged and backed up all over, kindamakes it hard to tell anymore

I think it's totally a case of misplaced expectation on ZtotallynakedZ's part... that much is obvious to me. So I won't hesitate to get reflashed once it's out for '05
ZtotallynakedZ, are you sure it's not becoz of your decked out sound system that's draining all the power?!?

ztotallynaked> i just wasted ten minutes reading this garbage, can i have my time back
my friend just did the hondata reflash and let me tell u something..for the 600 you spend if your not satisfied, and /or you dont feel a power increase. then i think its safe to say u been sniffin glue or something

cuz it either works or it doesnt.
and if it works, ud have to be an airhead to not notice it.
