pinging results in lean a/f ratio...retard the timing or adjust the Fuel pressure. 310 is suffiecient for a b20/vtec...any higher any youll just waste gas...But in a tuning aspect your big injectors will inable finer tuning of the fuelnb12 said:how's the 370 working out for you? MPG? Mine's still pinging a lil bit...
Yes you can...a wideband o2 sensor is needed as you know as well Tuning should be on a dynoH22AllMotor said:Jayman 320......you should still be able to tune you're a/f ratio with a V-afc....do you agree?
If you got the money look into a HOndata EMS, its way better and it seems tuning is your current project and youre building a monster.nb12 said:thanx Jayman....I guess I should have adjusted the cam gears when I switched over to the new compression (works great at +3 for intake/ +2 exhuast for the stock pistons)...didn't think much of it since I'm still babying the engine during the brake in period(haven't gone over 4.5K RPM yet). Was going to do everything on the dyno...but it's eery feeling when I'm accelerating. As for the fuel regulator...I've set it to 40...and it's pushing ~42 half OT...should I set it higher considering RC spec the injector to be 310 CC at 43#'s?...kinda new at this...thanx for your help bro!
PS...I'm almost broke but tempted to get the VFAC....do you think I should get it considering I'll be looking at 200-300 for the dyno time???...if only there's a couple more digits in my bank account...hmmmmm
