hey guys, just thought i would make a post about my SAFC2 settings and the effect they have had.

well my settings go from -6% to -16% as the RPM increases. the settings for the mid range RPM's made a noticable difference. upper rpm's still lag though.

and while keeping an eye on the AFR gauge, it still reads rich even when the corection is at -15% in third going 80mph.

i didnt have time to lean out the top end more. i have two tests tomorrow plus the turbo goes in so i will have to undo all the settings anyways.

the car definately gets to 80mph a lot faster but then the fuel curve gets too rich and the engine starts to bog down.

of all the mods that i have done to my car, the SAFC2, with minimal tuning made the most difference(not including the turbo, when thats in, it will blow away everything).

let us know something more from your next tests.
Also...can you post your settings accurately to do some tests!! >> >> >>
Thanks

i would do that but like i said, in 3 hours the turbo goes back on to have the down pipe made and after that my settign will be way different than for most ST's

i'm guessing that about -20% corection on the top end would make the car run in stoich conditions.

when i get a chance i will copy down my settings and post them.

Ok, thanks. by the way, I'm going to turbo setup soon so also when you do some tests, post them so we'll can compare results!!! >> >>

settings would be appreciate. I'm currently running to -12% max at 4800 rpm and I've had the same results. midrange power is increased and it pulls pretty well once off the line.

those settings look good bro. imma try them out tomorrow. >>

So will I, once I get my flaiming AFC I ordered a month ago...

Jon

well guys,

i guess your in luck. my mom broke her ignition so she had to drive my car around.

s0o0o0, i didnt get to put the turbo stuff on and missed the appointment to have a DP made.

tonight imm gonna mess around with the tuning of the SAFC for one last NA session and post the results for you guys.

Yah, I had similar settings until I started having a misfire and I pulled the plugs. I was running a max of -15% and reading the plugs, the car was WAAAAY lean. Don't trust the O2 sensor!!! Its not an accurate way to tune the car at all! The misfire turned out to be unrelated to the safc settings, but just a warning, be careful. I zeroed mine again until I decide what I'm doing with my motor or until I get on the dyno with the wideband.

oh, i also forgot to mention that since i have OBD2, i cant really mess with the timing, so that is set to stock.

and for these runs i was running 91 octane

That sucks about the timing....I was running about 13 deg base. Sounds like you're being careful and know what you're talking about, but be really careful!! Seat of the pants tuning is never all that close. Please please please spend the $100 or so and dyno with a wideband once you get your mods done. You will find significatly more power, guaranteed.

Haha, I always tune my RC cars by sound and by spitting on the head >>. That sounds kind of expensive for the dyno, you should be able to get on one for about half that. Where are you located? I might know somebody. Theres an AWD dyno about 5 miles from my house that I can get on for $75 an hour (also does 2WD obviously).

I'll do some checking and get back to you.
