How much did you pay?
Whered you get?
How do you like ect ect...

well it has *its* moments

 

Unless you already have I/H/E/FPR done then you won't have any need for the V-AFC. Your fuel mixtures won't need correction from increased pressure and engaging the VTEC earlier won't be utilized as well from the stock setup.

 

um no, the x-over on the f22b1 is too high not enough rev range, trust me i know

 

Doesn't Hondata say lowering the VTEC engagement point with the VAFC and stock ECU a BAD thing?

 

not that im aware of

 

Here it is man... from http://www.hondata.com...
"The Hondata method of setting the VTEC point is better than any other piggyback computer. Why? Hondas have two fuel and two ignition maps (***see the tech section****). With add on VTEC controllers, the camshaft is forced to switch while running on the wrong fueling and ignition tables. This can cause fuel to be as far as 10% out and ignition to be retarded up to 6 degrees. Some VTEC controllers allow a coarse correction for fuelling, none allow correction for ignition advance. The best method is to switch the maps at the same time the camshaft is changed. This is how Hondata modified ecus function."

 

true, but my distributor is pretty well advanced, that was going to be my next course of action i wonder how much their stage 4 is ?

 

Hmm can you really even feel the vtec? Isn't it like EX vtec in a civic. If you get an H22 the vtec controller might be worth considering. 22a

 

If I got the Hodata ECU (Stage 2) piggyback that would allow myself to remove the rev limiter and engage the VTEC sooner which from what I understand will give me a larger rev range with VTEC engaged. Has anyone used this unit on an Accord? I'm almost ready to get a used V-AFC from a friend from work. Let me know what you think guys!!

 

yes you can feel the vtec earlier, u certainly cant feel crap at the stock point

 

You deffinately don't want to consistanly rev/shift any higher than the stock fuel cut with stock internals.
What's up with your H22 VTEC Girl?

 

Ive got I/H/E all on the way there in ups hands on there way to the door
actually the intake i already got i have ordered a

DC 4-2-1 Stainless
Greddy Ex

Im working on getting some kamikaze headers but for right now i sided with the dc's cuase i got a killer deal on the brand new.
from a reliable friend so its better than the stock ive also order a msd6al from work and it should come in tonite or tommorow.
what did you mean by FPR?

 

FPR = fuel pressure riser.
The logic is it adds more fuel to the combustion mix to compensate for the lean mixture caused by the extra air I/H/E gives.

does lowering the VTEC threshold yield more power on F22s?

the answer is Hell YES.

i have all the proof from dyno graphs of my car when it was tuned... i've had the VTEC point lowered from 4500 to 3500 for over 2 years, with no problems. there was speculation that upon VTEC engagement, there would be too much stress on the oil pump to produce enough oil pressure, but this has proved to not by the case. between 3500-4500rpm, i gained 15-20hp at the wheels.

Hey Dunreit. Can you post the dyno charts and mods done at the time please. I would love to see the end result of your work on the F22 motor. Or at least just post the max HP produced with mods and point of VTEC engagement. Thanks bunches!!
