Timing Off??? well some of you guys know i'm boosted for about 6months now, but i thought i'd ask...
now boosting I know I need to get a piggyback ECU to compensate with fuel and timing... which I don't have, I only have VAFC2... my first question is
(NORMAL DRIVING) when i'm on first gear i nomally rev up to 5k rpm before I change gear... but my car hinders like it's choking out of air??? is my timing way off? this only happens on 1st gear NORMAL DRIVING, it doesn't happen when I floor it up to redline... VTEC set at 4500 <<<is this the reason why it kinda buggs down?
second question, if my timing is off, I already set up an appointment to get my ride dynoed, will my VAFC2 be able to change the timing? or I need a piggy back for this?
and yes, i read the basic boost guidlines... and I will read it again... like now! thanks for the input guys!

I wouldn't change the vtec settings at all. Leave them at the stock setting.
Normal driving isn't shifting from 1-2 at 5k.....i usually shift around 3 - 3.5k
You will not be able to change timing with the vafc....only the e-manage. Also, the vafc increases timing as is goes from vac to boost.

ow wow i didn't even know vafc increases timing... is that good? or bad? anyway, yeah i'll try to keep it below 4k RPM... thanks... i was just worried if i'm throwing a piston off or not...

Rep Power: 812 the vafc does not increase any kind of timing, only a/f and vtec. If you have the vtec set that high, you are gonna have a flat spot between 2500rpms and 4500 (where yours is set). That's already been proven on a dyno. Leave the vtec stock and I bet your problem is solved, especially with turbo.

of course when you retard timing you will lose power

Rep Power: 812 If you have the vafcII I promise you it does. That's the only way to get it stock. We're not sure on the engagement point, and it may actually vary depending on throttle position. Just play around with it and press different directions until the numbers become stars.

Rep Power: 323 The **** is stock setting you can get there by turning it backwards. As gearbox said this will solve your problem and improve lower end power.

Rep Power: 812 No there is a way to make the numbers disappear and turn into stars. Try pressing the little control thing to the right or something. There is a way, you just have to try different things in that menu.
