Super AFC N/A percentage corrections
#1
N/A percentage corrections
S5 N/A
Mazdatrix Light weight steel flywheel
Corksport Header to 3" single, no cat, single muffler.
AFC Neo
Innovate Wide Band located at the collector, no O2 sensor
Cold Air box, Cone filter, Cold Air Duct, and Heat Shielded Intake Track
155,xxx miles
100psi compression front and rear rotor
60% Hi
50% Lo
My corrections from 2000rpm to 8000rpm WOT start from -11% and progress to -23% correction (slightly different around where the ACV opens and secondaries), in the pro setting. My AFR's are low to mid 13:1 . Before the major corrections i took -10% at the most before i had a wideband, after install it was reading low to mid 10:1. The After Burn was insane, still is. Just not as earth shattering.
My question is, Is this common to take this this much fuel away on a N/A?
Side Note: it runs great i tend to dial it in a little more but im just curious about the other afc tuners out there.
Thanks, Vic

Bring out your dead! No one ever answered and I had the same question, so almost a year later i am adding my $0.02. I'm pulling 20% out on the high map and still in the high 11:1 AFR range. I didn't want to go any further than that until I got confirmation that others are adjusting as much as I am. Cant always just trust your wideband.

Does anyone use a SAFC anymore? I am jacking this thread as it interests me. I also may be able to offer some help. I just installed SAFC 1 and have no intention of going wideband. I have been trimming the fuel and basing removal on sound, smell and feel. Car is S5 N/A with S/4 keg. Port matched, Cheapie cone filter, custom downpipe and mid pipe, and cherybombs. Anyways, I have added fuel at 1000 and trimmed fuel progressively as rpm rises. I took no more than 9%. I will inspect plugs ion and adjust as necessary. I have a narrow band coming to assist in tuning. I have noticed an improvement already.

Why not get a wideband? Not interested in keeping healthy a/f ratios????
Small price to pay for a reliable tune. Also be careful will drastic changes and the ecu with adjust timing based on how you adjust your fuel because of how this type of piggyback works. These are only really meant for smoothing things out after simple bolt ons. Not really safe once beyond basic upgrades.
