I've been hesitant of flashes since the day I got my Evo and started looking at tuning options. I finally got to log a mod'ed Evo with a flash/custom tune.
The owner recently installed an AFC for additional tuning and asked me to log a couple of runs. I'm not sure what they loaded in that car, but the timing sucked between 3000-5000 RPM's. It was stuck flat on 5 degrees and refused to budge despite any adjustments to the AFC, richer or leaner. As soon as 5000 hit, bam, timing goes to 8 degrees and starts climbing normally. I adjusted 5000-7000 RPM's on the AFC fine, but could only get the timing to peak to 15-16 degrees.
It's weird. How is this thing holding timing for so long? If someone with a flash and a logger could log a couple of runs and post them, it would be appreciated. Is this a common thing with flashes? I know they have to keep things safe, but...
