I have to disagree with the above statement.

The reason being that most euro buyers realise they are purchasing a "medium sized (and weight)family sedan" and do not expect sports car performance.

That having been said, personally I believe, as many other Euro owners would agree, it is a great car to mod due to the potential of the technology that is built into it.

The lack of power/torque for a car with the euro's potential handling etc is a disapointment for many owners as the car, with similar power to the jtune xtreme package, (from the factory) would make it very competitive in the "sports sedan category" against turbo 4's.

My main gripes with the lack of power/torque in after 1 yr of owning a euro
is the constant downchanging gears around town due to the lack of torque.

Also, with highway driving, using cruise control in 6th gear I manage to get about 6.5L/100k's, however having to change back to 4th or 5th to pass (as 6th gear is useless for this) I find it a nuisance to have to constantly reset the cruise control. Now I've got some mumbo in 6th gear!

Speaking of a 5.0L SS 179kw Commodore VT, I sold mine in January, to be honest I was glad to get rid of it, piece of crap...IMHO
I had traded in a V6 VTi 147kw 98 Accord, great car, crap gearbox.
Anyway, that got me hooked on Honda cars.(Always owned Honda bikes)

The funny thing is Euro, VT SS V8 and 98 Accord VTi all have about the same power to weight ratio.
So, my last 3 cars would all do theoretically approximately the same 400m times.
If I really wanted to get to 100kph as quick as possible I would get a 1000cc road bike and do it in under 3 sec.

Having been used to 6's And V8's, what I was missing was torque.
By upgrading the power on my euro, I am now getting the torque I was after, but also have a damn quick car down the 400m.(for a family car)

Interesting to do a power to weight comparison.
(close enough anyway )


Euro Lux 1440kg - 140kw =10.28kg/kw
Accord VTi V6 1480kg -147kw =10.06kg/kw
VT SS 5.0LV8 1800kg -179kw =10.05kg/kw
07CivicTypeR 1345kg- 148kw =9.08kg/kw
06 Accord V6 1480kg -177kw =8.53kg/kw
Integra TypeR 1160kg -147kw =7.89kg/kw
VZ SS 6L 1660kg -260kw =6.38kg/kw

Euro Lux 1450kg -196kw =7.39kg/kw
(with jtune
xtreme if 40%gain)


Euro Lux 1450kg -182kw =7.96kg/kw
(with jtune
xtreme if 30%gain)

But, personally I was not after a car that would blow off Rexys at the lights, but a car that was tractable at low revs, and not have to be contantly changing gears. Love driving a manual, but lots of traffic and my busted hip and pelvis gives me hell! (note-Honda motorbikes don't have air bags!)

Having ridden large capacity road bikes, I liken it to riding a 1000cc road bike, compared to a 600cc sports bike on which the gearbox gets twice the use to to the revs required.

Anyway, having had the opportunity to do a lot of driving in different conditions this week with the xtreme package, I can honestly say it has exceeded my expectations performance wise.
It has turned my euro into a beast....lol.....almost

Okay, now who's gonna shoot me down?...............

Does anyone know what kind/figures of fuel consumption we're looking at with the Jtune extreme?

[Merlin086]

Haven't done a tankful yet but I've been testing with frequent redlining and my consumption is showing ....10.5L/100k's after half a tank.
I was going to report back after a tankful to do a proper check from full to full.
I live close to many 100k,110k and derestricted zones, hence many full throttle tests to.....ummmm...100kph......well, maybe 110, so I am surprised at the low reading on the odometer.

[cupnoodle]

Damn so much more power and not much more fuel consumption. Soso tempting...........just gotta convince the misses -_-

[Merlin086]

I'm gonna stick my neck out here and reckon on my next trip I can still achieve 6.5L/100k's

I generally get around the 9.2 so leadfooting it reading 10.5 is, well, friggin' unbelievable IMHO, but a tankful will tell.

[BiLL|z0r]

+ since it's a new "toy" consumption is gonna go up anyway as your "testing" it. After a few weeks and you're used to the new power band it should go back to normal or maybe even drop as you press the accelerator less to generate the same amount of power.

[BiLL|z0r]

Well I went for a ride for a few hours with Merlin today in his Extreme JTune Euro so thought I'd give my feedback. First let me just say he had a box trailer on the whole time as he was picking up his old exhaust so he couldn't really give it heaps, esp around corners. Also let me point out the parts are not final production on this car yet so it could differ slightly but it's pretty damn close.

Pro's:
Much better low end torque and usable power band. You rearly need any thing above 6k rpm. You don't feel vtec anymore though since it's almost always on if you give it a lil bit of stick.

Con's:
Exhaust is waaaayyyy too loud IMHO. Unless you're in 6th and literally cruising with little to no gas you can here it. It is a nice sound, don't get me wrong, but I did have to raise my voice and repeat the odd sentence because of the exhaust noise. It's especially loud with the windows down.
James marketted it as a quiet exhaust so I'd hate to hear loud. The sound does resonate a fair bit through the cabin. I believe different manifold bushings are

Comments, not good or bad:
You can't hear the CAI over the exhaust. I do personally like an intake sound over an exhaust sound.
The exhaust tips are big but not overly huge. You certainly see other cars with cannon's that are bigger. It's a personal preference. It would be nice to have a different shape. I quite like the stock shape of the oem tips.

Would I buy it?
Unsure but it wasn't final parts and not a true test since we had a trailer on the back. I'd really like to try a mild tune to see the difference with similiar mods. The amount of exhaust noise did put me off a little as it's much larger than expected.

I'll give it a go....

Sorry got to query those numbers.

If the Jtune hub dyno shows 125kw at peak stock and around 158kw with extreme that is 26.4% increase so around 177kw at the engine.

I am only speaking theoretically, hence the "if", so until the dyno is done after my ECU is back etc, I can only speculate.

But, is it reasonable to quote a 30-40% gain at the flywheel as the comparison I am doing is using manufactured quoted flywheel KW?

Besides, Yfin, u r still the quickest here...by far...

No, yfin's method of calculation is correct. You have to compare before and after readings on the same Jtune dyno to get the percentage gain, and then apply that percentage to the manufacturer quoted flywheel kW. So it's 177kW.

Sorry, but I can't do that as a comparison unless I put all the other cars on the same dyno...der...

Or would you like me to put them all down the 400m for u..............

[johnprocter]

so with the mild flash how much extra KW at the wheel would you get compared to stock?
