Rep Power: 325 I had the VAFC2 on my 02 EX with stock injectors and a t04B turbo. I never dyno tuned it but I added some fuel from 5000rpms on... Mainly guess work, I would rather have it rich than lean...
Anyway, I didn't have a dyno, but with those little adjustments after 5000rpms I was able to start spinning second at 6.5psi. Now im at 6 with the new HG and no VACF2. You can tell that that thing worked. I am waiting for my emanage with all of the harnesses, that thing has quite a bit of potentional so I figured why not...

Rep Power: 0 03 and 04 are having some slight improvemnet over 01 and 02. And the ECU just don't let you do whatever you want to do. I had installed VAFC-II too, and not work. The owner is my friend, he called and the result came back as it worked only if it is 01 and 02. 03+ just have too much compensation, just like, you can change the timing of valve opening, but it will also advance the ignition timing from the computer. Not good....

Rep Power: 318 The '03 models increase the timing too? I have an '03 and am think of getting this APEXi thing, but haven't heard of this different ECU thing. Why can't I just swap an 01 or 02 ECU into my car then?

Rep Power: 318 That's what I thought... but I'll call APEX in a day or two and if I have too I'll call up Honda to find out. This is the first I've heard of this idfferent ECU stuff.

Rep Power: 0 What strut are you talking about?
The 03+ ECU thing....You can plug in a OBD-II reader and look at the timing...Increasing and decreasing fuel will make the timing advance or retard(I forgot which way)....If you increase or decrease fuel, the only thing that will happen when you run the dyno is.....Less power than stock.....This is not what you want to get...The 03+ ECU is just too smart to work with.....
If you have F/A with 03+ dyno, then you will notice that the engine is running very rich already(5000rpm is already 12.8).....

Rep Power: 318 the struts thing... in '01 and half of '02 Honda had a strut problem with our cars as in they where blowing out, so they bumped up the size 3mm or something like that. If you buy struts for our cars, you'll notice Koni has two different sizes depending on the year, the number are barried though, but you can find it in the suspension section all over the place. Just look for a set of struts for sale, soem one will or has asked what size they are.

Rep Power: 318 It would make sences that the ECU would start to retard the timing if the A/F started going down, retardeding the timing is a way to prevent pinging associated with lean burn conditions. So then the only adavntage is with the vtec control and engine monitoring

Rep Power: 318 never mind... I looked at ur profile... I'm ot sure about that though, we have the bigger strut, but even the Koni's have to have a donor strut to cut up, which is why I still have my stock struts 
But I've not looked into type-S struts. I'd be happy with Si struts though, or naything thing that could directly bolt on.

Rep Power: 0 I installed VAFC-II and guess what?
Complete stock run, 4th gear......105.8....(When I tried to make VAFC-I to work)
VAFC-II, 4000rpm, I/H, pulleys, 2 deg advance, flat A/F curve correction, 4th gear.....108.5
VAFC-II, 3500rpm, I/H, pulleys, 2 deg advance, A/F corrected to 13.2-almost flat from 3k on, 4th gear....110.0.....
That's the end of the story....

Rep Power: 811 Usually tuning gives 5-10 whp on lightly modded cars. I'm gonna try and get mine tuned sometime. Every car is different. The main goal is to get the correct air/fuel mixture.
