TOV 2006 TSX review

[yfin]

Honda Jap web site now shows both k24 wagon and saloon with 147kw. Maybe there has been a change.

The 06 JDM Accord did not receive the TSX power increase - so it isn't always the case of keeping the best for Japan and it might suggest JDM is a different engine (ie k24a3). Much of the specs for the JDM accord are the same as the Euro - eg 4.4 final drive vs TSX 4.7.

I need convincing the JDM accord is K24a2 - I think it was a special project for the US market in the form of the TSX.

You mention the US being in the same boat as us re not getting the best models - I think we are in a worse position. There are some really nice Acura models here - as well as the incredibly beautiful Civic Si (see this) with 197hp, LSD, etc. Looking at one on the roads recently in the US and I was impressed!

Checked Honda japan's site. Seems that they have changed it. Now the specification data for the wagons is all in 1 table. It used to be in 2 tables, FWD and 4WD being separate. Guess they ended the 140kW model. I'll go home later and take out HyperRev Accord to get the info on hp and torque numbers.

The Civic Si coupe only started selling this year. Back in 2003, there was no 197kW Civic Si coupe. All they had was the weak Civic Si hatch.

for all of those with teh hard starting problem - get the dealer to reset the ECU's starting program... This fixed my problem but as was said in the article 10.5:1 compression is high for a road car so i suppose you can think of it as a trait of the car and not and issue

Was a good article - I still dont understand how the US versions make ~20 more hp and they only run 91 octane fuel ???

Bendix Ultimates are great pads - used them on my old car and a mates 180 and recomend them highly - just got to get them up to temperature

My car's slight starting hesitation has practically gone. It was never that bad for me, it just didn't like to start when I had a 5 min break in between. Anyway now that its completely normal I think it might have to do with needing to run in engine? I mean, I rev it like hell.


In the Auto - where the Sports Shift Mode gets much better times than the normal Auto mode, it is kind of weird. Don't think that difference is so pronounced on the Aust Euro in Auto. In fact, not much difference between the TSX's Sports Shift mode in the Auto and the 6 speed Manual not being flat shifted at all.


Regarding flat shifting - I don't really think there is so much 'shock' that it will completely damage the drivetrain with the clutch or the transmission. There isn't that much torque in the engine. I wonder if people in Aust have driven their Euro down the 400m strip while flat shifting?

US has different fuel rating standards to Australia -- their 91 is more like our 95+

Totally not true. It wears your clutch plenty, and since you are releasing the clutch so fast, the drive line shock is much higher. And it's not only your clutch and transmission. The driveline includes the driveshafts, CV joints, hub bearings too. Those undergo more wear from flat shifting.

Well obviously I said it in the context of the Euro Accord only. In other cars with a lot of torque you wouldn't want to do this.

You are speaking on relative terms, comparing flat shifting to normal shifting.

I'm speaking on the effect of flat shifting on a very linear but not that torquey engined vehicle.

Of course, what you said is true about more wear, it is common knowledge

Well, flat shifting on a Corolla Sportivo that had only 180 Nm did cause some damage to the driveline. The owner said that it was "loose" and gritty after that. That engine has less torque than the Accord Euro.

It's not because of the torque being linear. It's because of the speed of the clutch being released while the revs is about 2000 RPM above the next gear. Imagine when you shift from 1st to 2nd flatshifting. When you release the clutch at 7000rpm, your transmission speed is only about 4500-5000rpm in 2nd gear. That's 2000-2500rpm different and at the speed you're releasing your clutch, everything after the clutch (transmission, driveshaft, bearings, CV joints) is going to have to speed up. While the car is moving at about 60km/h, 2nd gear at 7000rpm is 100km/h. So everything is going to try to speed up to 100km/h, which is not possible. So your driveline will take a shock and if the tyres don't lose grip, the engine is also forced to jump back down from 7000rpm to 4500rpm. Even when not flatshifting, releasing the clutch fast during a 1-2 shift and applying throttle quickly after that will cause a very loud bang sound. That's the shock through the driveline.

At this stage the euro is best in class for the power it makes.....when some other car brand even tries to come close, honda australia will bring out the big guns and up the ante with the 147kw donk.

Withthe 140kw engine they run at the moment leaves the window of opportunity to upgrade at a later date.

makes good business sense if you ask me.

[EuroDude]

Or maybe bump the K24A up to 180kw I mean the K20A can make 164kw, whats stopping the K24A from reaching 180kw+ ?

interesting read.

i was sure that the Jdm and european accords had the k24a3's perhaps the a2 relates mostly to the 4.7 final drive? I'm pretty sure that the euroR final drive is 4.4... wonder why it didnt get the 4.7.

ALSO, this has raised a very interesting point. The peak gains found in the hondata reflash... In the US there were little to no peak gains from their reflash but over here with the prelimary results we've seen some very signifcant increases. I have a strong feeling that the engines are nearly identical for the 03-05 euro's and tsx's jsut differences in the tune
obvioulsly this isn't true for the 06 models as their have been some big changes.

Euro R has a 4.764 final drive, same as the DC5R and EP3.
