I'm probably going to run the smc+ on my setup
d15b7, 14b, dsm 450cc, 7-9psi

I'd just like to hear what some people who have used
the smc on a similar setup think of it?

I only really need the features the smc has,
and I have no interest in the safc's "blingin" looks.

so lemme hear it.

..I also heard it doesn't give you the wide range of tunability that the V/SAFCs give you. (+/- 30% vs A'pexi's +/-50%?)

Tad

actually it allows fuel cut of up to -59%
neither let you add fuel, so theres no + its only -

whats a voltage clamp?
would you say high/low throttle settings are really important?

TurboEF9

Uhm, V/S-AFC let you add fuel..

Tad

alrighty,
but then, what's limiting the map sensor voltage do?
is that what they do so you dont need checkvalves?

Tad

ah, you right.. did some lookin up

but that makes me wonder, if you can add fuel with the v/safc, then why do people buy bigger injectors?
why not just crank the stock ones up another 45% or so?

TurboEF9

Because of the method at which the AFC "adds" fuel.

I wrote this information into the Engine Management FAQ, section 2.
