4850 rpm VTEC point decreased from 6000 rpm
7600 rpm Rev limit
Maximum torque gain 28 ft/lbs torque at 6000 rpm
Maximum power gain 32 hp at 6000 rpm
Peak torque increases from 165ft/lbs at 4700 rpm to 168 ft pounds at 4700 rpm
Peak power increases from 201 hp at 7100 rpm to 204 at 6800 rpm
Very wide flat smooth torque curve. 90% of peak torque available from 2000-7000 rpm.
Passes Californian smog testing (no measurable difference from stock)
Fully dealer compatible - works with all Honda scan tools and equipment

i suggest you research about swapping for an aftermarket ECU on a bone stock car. increasing the rpm, lower vtec, etc. will obviously put more stress on the engine.

join honda-tech.com if you're thinking about tuning your car. they have a forum just for TSX models. you should do some research before you change your ECU. now, i don't know a lot about tuning cars, but researching before you tune your car is common sense.

Meh, the only thing that's going to add more stress per se is upping the rev limited. VTEC crossover has no effect on longevity. Hell, even upping the rev limiter won't do a whole lot since you don't sping 7500rpm on a consistent and extended basis.

i meant it puts even more stress when you have the pedal to the metal.

by the way, upping the rev limit doesn't necessarily net you more power. you need to tune the car after an ECU upgrade. buttdyno FTL.

Hondata is PROVEN to work well, many people has it, its not the 2 dollar junk ebay ecu crap.

If you think that is stress, you should talk to comptech about their S/C upgrade for TSX. That must melt the engine if it's that stressful.

i know it's not ebay junk. in fact, many people recommend getting it. the point is, the OP should research before he does any aftermarket upgrades. end of discussion.

He already did, he's on acurazine.com

Thats a nice ride

Doesn't necessarily up the power...but, at least in my experience with high-revving 4 bangers (H22 in the last car), it'll keep you more in the meat of the powerband when you upshift.

Please excuse my ignorance on the subject, I think the TSX is a great vehicle, but why on earth would a 2.4l 4 cylinder engine require premium gas? I see that it has a bit higher compression ratio (10.5:1) compared to other 2.4l engines (Chrysler's 2.4l @ 180hp/210tq is 8.1:1 using regular gas; Toyota's 2.4l @ 155hp/158tq is 9.8:1 using regular gas, etc, etc) but I'm still a bit

My Mazda3 S is a lot faster (also better handling and braking) and cost $17K

It allows for more agressive timing to get that 200 hp. Wait, what Chrysler 2.4 are you talking about? I see the Sebring is 150hp from the NA 2.4...., the PT Cruiser's 180 horse 2.4 is turbocharged (which means Premium is probably "recommended")

You can run 87 in these engines but the ECU will just retard the timing to compensate and there will be a noticeable power drop.

higher compression cars usually use higher octane gas, not sure why on the technical side. the integra gsr/type-r had even a smaller engine (1.8L) which required premium gas also.

was that necessary? you're paying for luxury in a TSX, not so much on performance.

8.5 with a slushbox I'm sure. This engine is simply a TERRIBLE match for an automatic trans.

Oh, what happen to your Saab 9-3? Or do you go around and trash everyone's car purchase?

Oh yes, definitely forgot to say GJ on getting the MT

The dealer I originally orderded the car at screwed up and delivered an auto TSX, same color, nav, etc.
I flat out said no and threw a fit at them for making such a big mistake.
I ended up switching dealerships and waiting another 4 months to get a 6MT TSX.

I test drove the auto TSX and it was somewhat adequate, but the sportshift (tiptronic) had such a huge delay, it was an immediate turn off.
For this car, it's stick or nothing at all IMO. The clutch/shifter combo is just a joy to row through.

That's nice. I was briefly considering the Mazda3/6 because I hear they handle extremely well for FF cars, but I needed a little more luxury and I think the TSX is just sexier looking.

Glad you enjoy your car :thumbsup:

BTW, stick or auto? S is the 2.3L right?

They say you can run regular in the TSX but you won't be saving money at the pump because gas mileage suffers, and you risk knock and ping.

It is the dynamic compression ratio that matter. For detail you can check Michael Delaney's Compression Ratio Explained

Basically, it is the dynamic compression ratio and ignition advance that determine what octane your gas requirement is. Or in reverse, the dynamic compression ratio and the gas octane that determine what ignition timing you should use.

Dynamic compression is based on your static compression (i.e. 10.5 in your case), your vacuum (how much you step on the gas), your temperature, your intake/exhause profile (your cam profile). OEM add safety margin in the design so if you put in 87, stomp on the gas from idle (advanced timing profile in high vacuum), it will retard the heck out of ignition for self protection.

Uberdata's guile to ECU fuel map/ignition tuning, very informative on how engine works


To make power, many engines are designed with high compression and very advanced timing and require high octane. To get efficiency, many other engines are designed with retarded timing. The same compression of 10 in corolla get 10BTDC (before top dead center), while Honda VTEC like Integra get 16-18 BTDC, one take 87, the other take 92.

New cars push it even further to match up the throttle and timing electronically (drive by wire) to make sure the situation where wide open throttle and very advanced timing didn't occur, and remove the reserved safety margin for more efficiency or performance. In older design timing is only changed after lean burn is detected by the O2 sensor. When that happen, it is reactive and already late (hopefully not too late). Drive by wire design detect your gas pedal position and control both throttle and ignition together, thus eliminate the chance of lean burn related knocking. The result? more power and fuel economy for you.

I have both (saab and mazda). The Mazda3 is the GT version with leather, heated seats, xenon, 17" wheels, auto climate, bose, sunroof, etc......

And according to Edmunds.com the TSX 0-60 is 8.5 seconds with the MANUAL transmission (Mazda3 S w/MT is 7.5 sec)

Those numbers stink. A 6MT TSX should be running mid/high 15's.

So do you have the MT or AT?

 

[NutBucket]

C & D TSX test: 7.2 & 15.6 1/4 mile

That sounds right to me.

The TSX actually has a better power to weight ratio than the 3 GT.
