2 questions on VTCS-->VICS
#25
With the timing wheel, I am not sure at what rpms/load the ecu retards the timing how but considering the idea of only adding intake side modifications, would it be 'sufficient.'
Let me clarify ya'll.. I'm not looking for huge power but if I could spend lets say $50 on DIY intake, $250 for VICS, then 2 or 3 hundred to tweak fuel and timing to run decent(IF possible), it sounds like I can potentially see 10whp.. But maybe I'm wrong, but that's what I am trying to learn.

Yes, AFR at different rpm points is important, I do understand this. I guess I am trying to ask if a AFPR or bigger injectors can support a modest boost in flow from say a intake/VICS.

Yes.
But for the MILLIONTH TIME, that is all irrelevant if you're too stupid to understand that this FLOW needs CONTROL, and your OEM ECU, does NOT PROVIDE this CONTROL.
If you're gonna be dumb, you gotta spend more money trying to avoid what we're telling you and still end up with dog crap.

You're ready to spend $600 on mods that really aren't going to do much.
Buy a MS used on here, tune it once with everything stock, enjoy a very mild power bump.
But judging by the fact that you won't modify the exhaust, and are concerned modding the intake will be too loud, you won't be doing much of anything at all.

I am unaware of how AFPR and or injectors change the amount of fuel injected. Scenturion made it sound like being at WOT changes something.
I realize that a X amount of increase fuel across the whole rpm band will mean that some areas will be more rich than others.
I understand that the NB2 runs pretty rich up top.
What I still don't know is if the AFPR or injectors run differently at open/closed loop and or if the amount of fuel is static rather than adjusted by whatever other condition.

Let me convince you to help me Let me google that for you
The answer is in the thread, you just need to convince yourself to do it.

2) AFRs tend to get much richer vs closed loop. In closed loop the ECU will run you at/close to stoich. In open loop its some AFR value that is much richer than that. a stock miata might run below 12. if you run enough mods, it might run at 13? You could put a turbo on there, add no extra fuel and run at 17 if you like. I also heard that moving the injectors to the exhaust side has some cooling benefits.
3 & 4) I will look out for your for sale thread.
New rule. if you have more negative props than posts...BANNED!
