hey guys i jus wanted to know you guys input on the vafc2.
currently i have
skunk2 megapower header
skunk2 megapower exhaust
skunk2 megapower test pipe
custom 3.5 intake
skunk2 alpha 70mm TB
and bc stg2 cams

i do have a emange ultimate but am probably going to sell and get the vafc2
some good info would help

b.r.i.a.n.

toss the vafc2 into your nearest trash bin and pick up a standalone ecu.

I took my f20C with Intake/header/exhaust from 185 to 205 RWHP with VAFC2 tuning alone. Is it perfect? No. Did it save me $800? Yes!

I made 204whp in my f20c with just a test pipe and exhaust with no tuning what so ever. Did I save $250+? YES!!

for NA all you really need is vtec control and injector adjustments. the difference between the 2 would be negligible

Is the vafc able go use injector adjustment? Or no. Or would I have to get fuel pressure regulator? Or is it possible I could install the rdx injectors and tune with the vafc?

b.r.i.a.n.

all the vafc does is target another part of the existing fuel table on the ecu to target the desired afr. that's it. the issue with that is that it also follows the ignition timing table. you have no control over ignition timing.

a fuel pressure regulator and larger injectors will do you no good since you have no way adjusting the injector rest time.

the vafc is an outdated hack. get rid of it. it's 2013. there are much better options out there.

If you must GEMU > VAFC2

VAFC2 as said above inadvertently advances timing when leaning out the AFR - do they work yes in a sense.
