ECU tuning ???

TurboGC8 · 03-30-2007, 02:49 PM

so what is out there as far as vtec controlling goes?
what is the best way to control the vtec for a decent price?

NIGHTHAWKSI · 03-30-2007, 02:53 PM

a hondata REFLASH...but there is no tuning for specific mods

iVTECpower · 03-30-2007, 03:43 PM

I am fully aware of the limited tuning options we FG2 owners have out there...but

...is it not possible to use a V-AFC II to control the VTEC engagement point? I called Apex'i and they confirmed that the use of their new NEO model does not work with i-VTEC but that their older model will. Any opinions on this?

NIGHTHAWKSI · 03-30-2007, 03:45 PM

i dont know much about that....but i am sure some one would have found about about it already if it was possible.

k20beast · 03-30-2007, 03:49 PM

go with the reflash...bc its already a good tune, vtec lowered to 4500, rev limiter raised 8600... etc

Jorg.Miekul · 03-30-2007, 04:18 PM

I have a pure stock Si-dan. Is it possible to get a reflash without any mods?

It's possible to get the reflash. But without at least an intake you will lose power.

the vafc II will adjust the vtec ebgagment point but that only controls the vtec solenoid and not the cam phasing or the fuel values. the vtec system is not just a set rpm point. the cam can change to the larger lobe but the fuel will not match accordingly

Really?

I'm dying for a way to get the lowered engagement point but I don't want to do any other mods. It's a dream that will never come true.

k20beast · 03-31-2007, 01:05 PM

u can not have a reflash on a stock car....the reflash changes the air/fuel so its expecting better flow coming in/out. thats where u need atleast intake/header

Why bother if you don't want to do any other mods? If you reflash without mods you will end up with the performance of a Geo Metro and you don't want that do you? So why not just be happy with the stock set up?
Besides just because the IVTEC engages at an earlier stage wont necessarily make it better. Actually, I have heard from people that have the Hondadata reflash that the sudden punch/switchover from regular to IVTEC is pretty much gone and it's just a smooth and unnoticable transition. So you will be disapointed all they way to the bank because you paid 600 bucks for a mod you wont get anything out of.

The reflash does make it better. After the flash you get more power 4500-6000. I would say the stock car is power starved in this range in order to make the cross-over dramatic. I no longer feel like I need to redline every shift when driving aggressively to stay in VTEC. It has much better driveablility. If the kick is what excites you then I suppose it would not be a good idea.

I am sure it does help and no the kick doesn't excite me that much. I was just trying to explain to the guy that doesn't want to mod his car that it would be a waste of time to invest in a Hondadate reflash if he isn't willing to mod his car.
I am still hoping that they will eventually release a tuner that will allow some adjustments on your part. Like timing or fuel air mix depending on which gas you are using or if you go to the track or maybe if you want to run Nitrous,
etc. The Hondadata reflash is the only thing that is out there right now which doesn't give us much of a choice. And it is really expensive.
If it were $250-300 bucks I would probably invest in it but for now I am waiting for something better to come along.

I would stay away from the vtec controllers on the Kseries motors, they do more harm than good with the new i-vtec motors

enter801 · 04-03-2007, 10:30 PM

Where do you get that from?

Anyway - yes there are TWO i-vtech and air/fuel controllers. The first is the Camcon by Power Enterprise USA, and the second is the Greddy V-Mange which is also a vtech and air/fuel controller. Both are fairly new released.

yep, thats what the hondata web site says... BUT you will still have the higher rev limit.

broda1115 · 10-11-2007, 09:48 AM

Is there any update on when or even if a reflash will be coming out for the r18?
