anyone with the smc+, what do you think ?
 

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.

Re:anyone with the smc+, what do you think ?
 

takes time to adjsut, no high/low throttle settings, and the voltage clamp on my smc500 stopped working

Re:anyone with the smc+, what do you think ?
 

..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%?)

Re:anyone with the smc+, what do you think ?
 

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?

Re:anyone with the smc+, what do you think ?
 

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

Re:anyone with the smc+, what do you think ?
 

voltage clamp limits the map sensor voltage, and the hi/low throttle settings would be nice to have, cine this just uses the same amount of correction the whole time

Re:anyone with the smc+, what do you think ?
 

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

Re:anyone with the smc+, what do you think ?
 

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?

Re:anyone with the smc+, what do you think ?
 

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

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