ok so i have my rsm in now and i saw this think its a s-afc II it allows you to tune your car for the mods you add. does any one have one of these and are they worth it? i plan on doing some little things to my tc nothing internal just bolt on's and a port and polished head. would this help alot??

also if any one has directions for the new style rsm in english please send them to me the only ones i can find are for the old ___ one thanks

I've had one before and I don't think it's worth the money. If you end up going forced induction or doing serious modifications, you're probably going to chuck it.

moved to power hungry tC...

u can use safc-2 on scions?? i thought they only work for hondas. i have it on my rsx with i/rh/e. after dyno tuning, i gained 10whp/12tq. i'd say its worth it if u can find it for under 200.

that is what i thought that they were only for hondas but i saw one of the sentra guys that is hanging out on our forum has one so i guess there universal this is the honda one http://apexi.com/product_electronics_detail.asp?id=201&pageNum=1

my question is how do you tune the thing? do you have to have tuning experience in it.

i guess a dyno would be good and also some thing to let you know the air fuel ratio (i think this thing is supposed to let you know it but im not 100% sure )

I've got the directions for the new RSM-GP, however, I can't find a pinout for the ecu to wire it in. I can e-mail you whatever directions you need if you can tell me how you wired yours up.

No, it's not a Honda specific application. An S-AFCII is an air flow controller that lets you lie to your ECU. While it is possible to gain 10hp by properly tuning your air/fuel ratio, you should also consider future modifications before spending $300 on this. If you know you're going to turbocharge your car, you'll probably going to want to be able to adjust the timing and you'll need something more powerful. I sold my old one for $200, so if you look around online, you can probably find one around that price range.

would it be pointless to get one if your going to supercharger the car?

^maybe. depends if the s/c comes with a ECU reflash or not. if it does, u gota take the safc-2 off. if no, then u can dyno tune with the s/c and gain more power with better gas mpg.

so the safc-2 DOES work for the tC? if it does, i'm gona get it. before anyone tunes the thing, they should be sure they are NOT going to add anymore bolt-ons b/c it would mess up the a/f settings u have already tuned for. so be sure u have the big 3, i/rh/s-pipe/e, then tune it and u'l be set. u have to take ur car to a dyno w/ a/f readout and the professional there will tune it for u.

safc-2 however cannot tune cam angles or advance timing.

if you pm this kid joe@dezod he has one in his tc and im sure he wouldnt mind helping you oout with any questions....and i ordered one for my tc aswell....

i thought he had an rsm

i thought he had an afc but maybe he has a rsm...but pretty sure its a afc...

yeah he has an rsm he used it to do a nice little suspension test http://www.scionlife.com/forums/viewtopic.php?t=48028&highlight=

EVERYONE...

S-AFC-II should not be used to fully tune your car... It only adjust every 600 rpms... so in between that you can be going lean... This is for the added fuel for cars that have reprogramed ecus or standalones that just to on the spot adding of fuel, for test purpose... That or to look cool in the show... I had one on my xB... theres no instructions in it yet for tC so if you do it your doing it on the fly

the new s-afc-II does it in 200 rpm incremints doesnt it?

the black on black... is 600 it use to be 500

I put an SAFC (blue screen), AVC-R, and TurboTimer on my Escort. Took me about 3 days to figure out how to make it wire up but wasnt hard. I ended up just adding a 2BAR MAP sensor off of an 88' Turbo Sunbird and spoofed the throttle position signal to the AFC (and AVC-R)

safc-2 is increments of 200rpm. the old safc is 500rpm.

then they changed it cuz when the new black on black came out that I have its 600

You can adjust the rpm points, but it won't usually go lean/rich between point becaus it extrapalates (makes up) the rest of the curve between the adjustment points, that's why you have the ability to change where your adjustment points are.

At this point you may want to hold on the SAFC II if you plan to supercharge your car. For those who say that it's useless I disagree. I have an SAFC II on my 99 Solara running 14psi on a supercharger. The car was running extremely rich with the larger fuel pump and injectors. The SAFC II allowed me to safely lean out my motor to squeeze out huge amount of power.

Check out the latest issue of Modified Magazine. I was reading an article about a new VVti / Vtec controller. I may end up getting this for my fiance's tC.

anyone have one in their box and actually taken it to dyno? i would like some help fine tuning so i don't waste $ on dyno
