i dont have access to a dyno in the area but ive been going to the track alot lately. i have pretty consistant times. 13.6's @ 99 mph i had 4 consecutive runs like that.
I was wondering about adjusting the airflow how much is too much when adjusting it. i wanna increase the flowmore. i have Vtec activating at 5k and Fuel is increased 7% Lo>HI and is increased 2% Hi>lo. i was just asking for a few tips. and please no comments about taking it to a dyno and tuning it. i dont have access to one. i gotta drive 3 hours away which i really dont have by the time i get off work.

 

I think I threw a code 3 when I surpassed +17 on the HI throttle adjustment map. I think we're pretty close in elevation with similar engines that you can reasonably expect a simlar threshold as well.

Even if you can go that high, it may not do any good. There may not be an increasing fuel load column to look up must past atmospheric, so the pulse-width will probably just stay the same. After a certain point of continually adding fuel with the AFC while I was on the dyno, the AFR's wouldn't come down no matter how much MAP voltage I added (up to maximum MAP voltage threshold where it trips the code 3).

What engine, cams, and ECU are you using?

 

Thanks for the info any one else care to put in some input

 

You dont have access to a dyno but anyone has access to a personal wideband to see the changes in AFR being made due to the AFC.

 

very true but i dont got 400 bux for one right now so im just trying to make the best of what ive done so far. i dished out 700 for the AN-R header. and 350 for the VAFCII and another 340 for the Koyo Full core radiator. so funds are pretty much gone right now.

 

there is really no sense in trying to add fuel with the vafc, ur better off getting an FPR for that.

personally I wouldn't mess with it too much w/o a wideband, its like shooting darts,

 

i got a FPR i have it set to 42 PSI

Exactly my point. Why do guesswork on a motor you've put so much into already? Be patient.

 

yeah im about to order a wideband and a vafc II because there are not any tuners in delaware. I might make a trip if I save up some money later and go to inlinepro they are in virgina right?
