hey i have a quick question about using the s-afcII in the tC...does anyone know what the sensor number should be when you have it installed? i tried a few different numbers but couldn't get the right one then i ended up throwing a CEL. anyways i was just wondering if anyone out there might know or have one installed on their car.

 

sensor number? u sure u hooked up the wires right....

It should be the same as the xb was search for it in the xb forum I posted it there I think or somone else did back in the day when we were first installing them in our xb's

 

I'm pretty sure I have the wires hooked up right. The sensor number I'm talking about is when you do the setup for the s-afcII. it says sensor type....hotwire/flap/pressure/karman.

 

you want karman

 

So I hook it up using the karman setup then right? i tried that before and the car ran really bad. it sputtered and ran really rich. maybe i'm cutting into the wrong a/f wire. do you know whcih one to be exact then?

 

I have the same problem as you. I checked my wiring 3 times and tuned the thing 3 times two. The same thing happens all the time. CEL,CEL,and CEL. My tC would not shift into 2nd gear and it would not go over 2000 rpm it would stall. So, if you have fixed your problem let me know.

 

I couldn't figure out what setting to use either so I ended up giving up on it. I tried pretty much every setting on it with no luck. someone told me to try hotwire 01-01 on toyotanation but i already pulled it out by then. maybe it mite work

 

I heard the SAFCII becomes overridden by the ECU after a while? I know the Celicas have this problem and is practically useless for them, also I heard you have to adjust it to 60/40 as Lo Bux Racer said.

 

Bump and so I can watch this.

I was considering getting one of these for some NA upgrades, so I'd be very interested in hearing from anyone that's got it working consistently.

 

was going to through it on my tc but at the last min. we decided a turbo grand prix gtp would be cool so its on that project car now


it realy seems like the unichip is what were going to have to do since the ecu wont be able to correct that but well see what Sound performance has to show when they finish there turbo tc im sure with the piles of 1k hp supras they have bulit they might have learned a thing or 2 about toyota ecu's or rahter wired up alot of stand alones lol


but im sure they will get our comunity some info

 

I will be going the camcon route. Dont think SAFC will hold settings/be over ridden...

 

same thing has happen with the camcon to there is no safe route except poslby the unichip since it modiffy out put of the ecu rather then the input

 

Sorry to have to correct you but ever since I tuned my car with the camcon I havent thrown a cell. I dont have any antifoulers or anything other than one high flow cat and one stock resonator everything else is just peachy I have a turbo and I havent thrown a cell in over 2 months now. CAMCON blows for turbo tc's it only helps on A/F settings for the record. CAmcon has really helped me in terms of controller my A/F other than that its worthles to me.

 

unvdistc had a comcon for a while on his tc and it ended up throwing a cel after like 2-3 months and was correcting for the fuel and timing adjustments

i know there were atleast 2 other reports of this but he is the only whos name i know

 

Would reseting your ecu bring its fuel maps back to square one? If so you'd just have to reset evey once and a while.

I have a camcon I will be installing and will be using it barring problems through next years rebuild with HC pistns and P+P, so you guys will get some in depth posts from me.

 

if u go p+p and go higher comp pistons and header and full exhaust and intake... I dont think camcon will surfice... your gonna need a piggyback or a standalone...

 

I would initially agree. I have the camcon for now, well see how it goes once I do the rebuild. i have no problem running an emanage or a unichip instead if needed.

 

I got my SAFC II to work today and man does it feel like another car. Once its at 4800 rpm under full throtle the car takes off. I did a whole write up at yoursciontc.com on how I got mine to work and how to install it.

Heres the link and enjoy..........

 

what size injectors were you using with the safcii???? were you tuning on a dyno to keep an eye on your a/f reading?? if you were using the stock injectors with the safc and trying to tune it you may have leaned it out way too much below 4k i know when i got my baseline dyno on my tc it has a perfect a/f ratio until 4k untill it gets kinda rich.

just my $.02

 

I only tuned the car above 4800 rpms. So, I would not have that problem.
