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).

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.

thanks for the warning.

i messed around with the settings a little(2-3% difference) and didnt make too much of a difference.

i tried having the low throttle curve set all to -20% and after cruising around for a while i pulled over and checked out the engine, mad sure it wasnt running too hot and that nothing broke.

i noticed the best improvement when the corection was at -15% on the high throttle curve. it definately pulled harder but for some reason the roads were populated tonight. i didnt get to do too much.

if i wasnt going turbo, i would keep the settings i had before. i drove with those settings for most of summer and havent had problems, but where i live, its hot all the time. it might have something to do with why i havent noticed problems with my settings

btw, i plan on using my dad's EGT tool to see what my egt's are when i have the downpipe made.

that should also help with tunning before i get some dyno time

just checked my plugs and they look normal by my chiltons manual and several on line pics. no signs of any problems
