for a while i was set on getting a chipped p28 to tune my car. however i decided to not mod my car much more than what i have now. so all i want now is just a decent tune of what i have - just minor bolt-ons (mainly i/e/h/p). so should i just try to pick up a used vafc for about 150? they seem like they are much easier to tune. for the chipped p28, it will take 175 for the ecu and basemap, and then another 1-300 to tune it. the reason why i changed my mind is because i have a very mild n/a setup (no internals or anything).

so who supports this idea?

 

your gonna spend around the same amount of money to get tuned on a vafc as you will with Crome/p28

vafc - 150, tuning - 125

p28 - 175 , tuning - 150, Crome - free


50 bux difference to get a tune 10x better.

 

tru, but also the object is to save as much as possible. how much would the difference be? like 2-5whp? i wouldnt really kno. also i dont really kno anyone who is already familiar with crome on the island.

the closest tuners from my house (who i have heard are pretty good tuners) are not familiar with crome. i asked them about it, and they said that they would have to take some time to get familiar with the program, but would not charge for that time that they take to get familiar with crome. so if i wanted to tune through them, i would probably have to get crome pro along with a datalogging cable, which would be another 150+30 right?

 

vafc
crome P28

I'm using a chipped P28 ecu with crome on my H22...much much better....a good rule of thumb is not to be cheap with any kind of tuning...wether it be boosted or N/A

check out this website
http://www.intecracing.com/ they tuned my car with crome and have lotsa experiance with it..ask them some questions! good luck mang!!!

 

what are your mods? and how much more did u make on the p28 than the vafc?

it may not be much of a power difference, but the car will "react" much better, your throttle response will be better, gas mileage will more than likely be better, your torque graph will be better, do i need to keep going.......?

 

wow excellent numbers for what u have. what kind of dyno was it and what gear was it in?

i guess ill stay with the p28

one more thing - is it safe to drive on the basemap for a while that i get from phearable?

 

i drove around for a few weeks on it before i was tuned. You will prolly get less mileage out of your gas so you will want to get tuned asap.

 

yeah.. you'll probably run hella rich.. (like i am)

 

good choice It was on a Dyno Jet....3rd gear pulls 17 of em

 

Why do people always give the vafc a bad rap when almost every guy I know with a 240 has one on their car makin' insane HP?

 

240's have vafc's?

 

some of em...you use em to controll the 2ndary injectors I belive??? and this is "HONDA-Tech" not 240-tech, most people don't have the money for a full stand alone EM system. A VAFC or a SAFC is a cheap way to adjust your A/F ratios..but it lacks the capabilitys to adjust timing if im correct....I listen and learn from people who have been doing this alot longer than my 4 years and crome is by far better than a FMU and a VAFC/SAFC.....Crome pro is better than crome..but for a NA car you really don't need it imo

of course you "need" Crome Pro with NA. It makes tuning time go down drastically with map tracing and additional plugins that you can get.


a VTEC afc would have no use on a 240...........a Super afc...yes.

your right wasnt thinking.......

oh and a side note(off topic )

98vtec you tune with crome?? well using just the basic crome program we got those numbers(on my car) with 17 pulls and 1 hour of dyno tuning..how would "PRO" make it more tiem efficient??????

(not to thread jack )

 

no its no problem, i would like to kno the answer as well. also, whats the biggest difference between the 2?

 

yea i tune with Crome

Crome pro allows you to map trace. It incorporates the wideband into the Crome program. You go into "live tuning" and you get a blank table. When you start the live tuning and start driving, the cel's start filling up with your a/f in each cel you enter.

say you do a WOT pull, basically the last 2 columns on the table. In live tuning, it will show what your a/f is per cel and you can make changes as needed. Thats why it makes it simplier and faster. There is NO guessing as to where you need to make changes. It helps alot with part throttle tuning.

theres just alot more things you can use with pro which make tuning much more friendly and time efficient, map tracing is just one of them.

 

hmmm food for thought!
guess my tuner is a wiz.....I am planning on running a stand alone Aoexi PFC when I start my gt35 turbo build so no more crome but as for now NA what can i say? I love the results and love the price! lol
