I can't wait LOL!

Anyways, me, yfin and Euro77 were down at the workshop where Euro77 had his VAFCii installed and dyno tuned.. while it was being installed, I nudged my tuner to let me do two power runs on my car LOL.. Power came up the same as last time.. Dammmm :(

Back to Euro77...
His figures which I shall not reveal but let him have the honour... is preeeetty impressive with just the VAFCii installed...:D

Thanks to Technik Tuning and Nick who organised it, I finally got my VAFCii installed. I was very happy with the power gain. I got 113.5kw running at 4th gear, over the stock 106.9kw (also on 4th gear). This is a significant increased compared to my lousy dyno run the other day at beninca, where I only get 101.1kw (running on 3rd gear!).

First impressions - the car is a lot more responsive, even with air con on! Hit the VTEC a couple of times and damn the car was on adrenalin rush. One thing I really want to see is how it affects my fuel consumption, since my car was running rich from factory (confirmed by the tuner).

A few pics of my dyno tune today:

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?

euro77
23-04-2005, 06:00 PM
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.

http://www.ozhonda.com/forum/showthread.php?t=14475&highlight=personality

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.

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

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

BLKCRX

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.

I hardly rev up that high. Maybe I should let my Vtec exercise a bit more often, otherwise it's muscle will get wasted and become rusty. Tomorrow will be a good opportunity.

Ermmm Euro77, we set your final stage VTEC is set at 5500RPM :) as this is found to be effective on your car... And the car has had the fuel cut so you should see your consumption get better... :)




i thought v-tec cuts in around 35oorpm?? or am i gettin it wrong with turbo...

The i-VTEC has a three stage system where different RPM kicks in different stage...

From memory it's 2500RPM, 4000RPM and RPM for the Euro, except in Euro77's case, it's now at 5500RPM :)




James, we really look forward to more updates on the Hondata for the K24A :)

cool to see such good gains with the vafcc (or however you spell it). this is making hondata look all the more promising :D and 25% gain!? That'd be what... 35kw somewhere in the rev range? make sure you keep us filled in on the progress

EURO77 & Nick,

How about the mid range improvement from tunning the car using VaFC2?
Would be interesting to see if this has similar result with comparison to Hondata reflash

EURO77 & Nick,

Would be interesting to see if this has similar result with comparison to Hondata reflash

When I spoke to the tuner he said almost all gains would be above 5000rpm. The tuner also said the reflash gives Hondata far more points of tuning than a piggyback VAFC - eg rev limit and cam angles, etc.

baboo
26-04-2005, 08:59 AM
yeah that's what I thought.

I don't think VAFC can adjust the cam angle.

K-series engine response extremely well to the cam angle adjustments.

26-04-2005, 09:35 AM
I thought stock Euros had the high lift cam (3rd stage) engage at 6000rpm?

euro77
26-04-2005, 07:40 PM
I'm pretty sure the VTEC kicks in at 5400 rpm.. I read it somewhere.... :confused:

yfin
26-04-2005, 07:54 PM
I'm pretty sure the VTEC kicks in at 5400 rpm.. I read it somewhere.... :confused:

High lift is at 6000rpm - from the TSX technical manual

The TSX uses a variation of this technology that is very similar to that of the NSX. With three rockers operating each pair of intake and exhaust valves in each cylinder, the TSX powerplant varies the opening lift and duration of the intake and exhaust valves. At low rpm, the valves follow low-lift, short duration camshaft profiles to help boost low-end torque. Above 6000 rpm, the intake and exhaust valves are operated by high-lift, long-duration cam profiles, for maximum high rpm horsepower.

euro77
26-04-2005, 07:55 PM
hmm.. ok.. I stand corrected. It must be something else I read.

albii
26-04-2005, 08:01 PM
yeah 6000rpm 90 kmh in second hey yfin?

yfin
26-04-2005, 08:14 PM
yeah 6000rpm 90 kmh in second hey yfin?

Yep - 88 or 90 sounds spot on.

yfin
26-04-2005, 09:55 PM
so... its not possible to have both hondata and VAFCii?

Yeah it is possible to make them both work as the Hondata is a reflash and the VAFC is piggyback. Theoretically you could get a tune of the VAFC after getting Hondata - query whether the gains will be there though. You could probably lean some more fuel out, etc. Most people will be happy with just the reflash.

BLKCRX
26-04-2005, 11:49 PM
Hondata will not work with a VAFC, or VAFCII or any piggy back device. Hondata is tuned and must read the correct values given from the sensors in real time, not an interoperated signal from a VAFC device. Yes it would work, but doing so could and would do massive amounts of damage to your engine as the ECU would then providing incorrect fuel ignition and cam angle at 9600 different points for the wrong MAP RPM and TPS value, this is a big no no especially when your car is already tuned, not 2 mention the obd2 self learning long term and short term memory, and the complex ignition regulation system the k24 engine has.

FINALLY got my Apex'i SAFC NEO install + tuned by IS Motor Racing :D
mods i got installed on my euro are HKS exhaust + comptech intake. other than that all dead stock.
also keep in mind this is only a AUTO so should be much weaker than a manual i guess :P

Hey bustersonic- do you have a base line graph you can post up?

what vtec point is that?

power curve seems interesting but i don't know what a standard auto graph should look like

So the people at IS Motor Racing confirmed to you that they managed to get the NEO tuned for the K series engine?


Good output BTW for an Auto!! :D :D

112kW at the wheels on a dyno dynamics is good, especially for an auto with only I/E.

ya i guess works with k series :thumbsup:
sorry don't think a basic line graph, but to what i remember is that just before the oem setting vtec there's a major drop in kw. the vtec point now is 5400, so the drop's gone. u can see there's one pixel at the 5400 which is down a bit, that's the drop, it has been minimize to the max LOL

EuroAccord13: when's your vtec point? and how much kw now?

Doesn't work like that if you want an accurate indication of improvement.. Just ring up IS Motor tomorrow and ask them to send you the base line graph.

Mine is currently set at 5500RPM with close-out at 5200RPM... 126Kws at this point of time....


Everycar is different and the same car with the same mods may utilise different engagement points in the controller, your one may be 5400 and another guy with the same car and mods as yours may be engaging it at 5700rpm...

The main thing is how does your car go now with the controller?Much dif?Where do you notice the dif.low,mid,high?

mainly the mid area, but i believe i could of got more kw shown if i used v power 98... lol cos yesterday ran out of fuel and used vpower racing 100 for the first time... reckon can get more from 98

why get more from 98??????

V power racing has some ethanol in it. Ethanol produces less energy per volume. But you can take advantage of the higher octane rating to increase the compression or advance ignition timing to gain more power there. But for an engine with stock timing and just a fuel controller, 98 with zero ethanol should produce more power than 100 with 5% ethanol.

shit... 128.8kw.. omg. that's crazy, and only a ebay header.
makin' me wanna get a aftermarket header now + the pulleys. but does pulleys actually affect your kw output, because i thought it's good because it is light.

Are the dynos even the same brand?. He has pulleys and his is a manual as well. Bustersonic's is an auto. More drivetrain loss there.

MUGEN88 got basically almost the same mods as me but he has pulleys as well, the NEO is not even fully tuned...

Just wondering, how much was spent to get that 8kw increase? (or 5~6kw increase thru out the rev?

Aint the air temp going to effect the powerout put? thats like 6-7deg diff between the base and final?

Any torque curves?

sorry to revive the thread.. and i did a search but didnt really find what i was after...
Vafc/vafc2 is there a didfference and which would be better for my euro?

which comes to my main question... i have an 03 man euro with cai only, if i install a vafc/2, would it be worth it? and how much more fuel efficient will it be? and if its ok if i adjust the vtec cut in point earlier say 5000-5500rpm and still runn if safe without blowing my motor??

some feedback/info be great thanks guys!! =D

NOT WORTH YOUR MONEY PLUS TIME with just an intake... mayb come back to this topic after u get some decent exhaust n header n intake.

Don't flame me, but how come no ones actually getting the advertised 140kw @ 6xxx rpm or whatever? false advertising? or is it something to the effect of "advertised 140kw, ~100kw effective"?

that's KW at the fly. the dyno we have are showing the KW @ the wheel, so the power u putting into the rubber onto the ground

I'd suggest not to get VAFC/VAFC2 as the ECU will re-learn and override your VAFC/VAFC2 settings.

Oh ok, is there other vtec controllers out there that wont overide by the stock ecu? or is it always gonna relearn untill i get an after market ecu? how about a piggyback? or is that the same as a vafc/2??

I would not lower the vtec point with just an intake. Honda tuned vtec to kick in at the optimal moment, with just an intake i dont think there is much reason to change it unless you decide to do more extreme tuning.

lowering vtec wont make you loose power... you just may not gain anything and you will loose fuel economy...

vafcII is basically a piggy back unit, all piggy back ecu's and controllers interupt the signal from an engine sensor and then send a slightly different signal to the stock ecu, this will make the car run differently :D its basically the same princible as those resistors u put inline on ur commobore intake temp sensor so the engine runs as if its cold and you get more power, except it goes a lil bit more complex than that...

as others have said (i can confirm from personnel experience) the honda ecu is very quick learner... only took 2days from my rbc swap for the ecu to completely re-map its idle and running setings... not sure how the whole vafc re-learning goes, but the settings probably wouldnt stay all to long :(

Your best bet is doing a reflash. If you want, read up on the J-Tune reflash, and decide if you want it or not.
