You'll get more power by ditching those 18s of yours Nick! Seriously :p:p:p
So you actually have a gain today :D

The 18s on Nicks car prob weigh 12kg each compared to 8kg for the stockies!

Nick where did that 102 kw figure come from - the first dyno stock run for Euro77s car? Perhaps the gain is 102 to 113.5?

If I remember correctly, the first run is 102 (VAFC not tuned), then the tuner did a couple more run (still with VAFC not tuned), and it sorts of fall at around the 106 mark, with one run getting 109. 106.9kw is considered the stock run as most figure falls in that area.

I see. The ECU on the Euro must be really complex -the difference, for example - between 102 and 109 is significant. The temperature was roughly the same so it is rather odd. There is not really much consistency with the Euro - eg my old post based on my butt dyno was right. The car has a personality disorder.

The guys at Technik were saying that the ECU on the Euro reads lots of sensors including barometric pressure!

I think if you took your car to be tuned on a day where there is different conditions in the workshop - you might get a totally different tune, results etc.

I know Euroaccord13 has got roughly the same figures consistently - my butt dyno, however - tells me this thing is far more temperamental. And it is not just temperature - it is more complex than that.

the euro is alive, more alive than the lexus gs LOL

Hey Euro77,

can VAFC2 change the Vtec cut in point? like VTEC cuts in earlier like say at 5000rpm?

So, what other mods have u got on the car?

yes, you can set the VTEC point, but according to my tuner, he found that the factory set one is the best.

Hey Jimmy, visit my vbGarage :D

Ahh...so the only mods that can affect your dyno readings are the condenser and the VAFCii.

Impressive work by your tuner then Ig.

Good on ya! :)

good to see the euro making good power with min mods..well done...
but just a question............a few people have told me that there is no gain in going aftermarket exhaust as honda does a good job standard ...(just like vtec cut in point) but air fuel ratios and timing are the way to go only....like vafc2

All Honda ECU’s for the past 15 yrs have had Barometric sensors (apart from some aust car’s where Honda aust wanted to save money !)
Tuning the k24 engine like the k20 engine responds very well, it a lot more technically challenging those than fuel and ignition, there cam angle which is where all the power is gained, the Honda ECU k24 has over 9600 tune-able points, in a 3D mapping axis and once you can harness the power of tuning that correct say hello to 25% more power ;-) like we already do on the k20 engine.
As for Dyno Variance between run’s .. yes the Honda ECU learns and corrects adjusts and changes all the time, unless you can control this directly you can’t stop it.

Thanks for your post James. We look forward to hearing good news about Hondata for the K24 in Australia!
