dynoflash????
Reset everything to Zero, otherwise you'll be running mega-lean. Mail-in Flashes are usually pretty close to the ideal A/F ratio. Dynoflash sets it at 11.2 from 4000rpm-7000, which i leaned out further to 11.4.
I had a difficult time tuning an AFC on top of a flash. The timing would not budge between 3000-5000 RPMS despite any fuel adjustments. Only after 5000 RPMS would the timing start to advance and this was after numerous pulls with a logger. Even then it still would not even meet stock peak timing of 20 degrees.
I've asked here and in other forums for people with flashes to post logs, to see if it was a fluke, but I'm still waiting...
If you have an AFC already, just use that. You will have more adjustability and an easier time tuning it alone, then on top of a flash.

It was a flat 5 degrees from 3000-5000 RPMS. Despite any adjustments I made with the AFC at those RPM ranges it was stuck on 5 degrees. Depite stupid pig rich and "should be knocking" lean it would not budge. What ever timing map was loaded into that ECU sucked. After 5000 RPMS then it started to advance normally, but it's so late it would not even meet stock peak timing of 20 degrees.
Timing advance is crucial to tuning these cars. We can't directly see knock, but it can be interpreted from logging timing advance. Flat spots and pulled timing will indicate knock long before you hear it, before A/F ratios, and EGT's. A good steady timing advance through out the entire RPM range is what I look for.
How can you properly tune the car between those RPM ranges if it's stuck/preprogrammed to be flat?
So again maybe, this one was a fluke. If anyone can log a flashes timing advance, please do, and post it.

Try an enmanage.
Hundreds of guys have used a SAFC on top of my flash with great success.
It sounds like your individual car has some issues - 5 degrees of timing is way too low.
It seems very backwards thinking to be trying to adjust your timing advance with a fuel pissgy back. . . . anyway i am not suprized that the intended result was not achiveed with such crude methods.
I understand the concept of advancing timing with an SAFC and Dave Buschur has posted about this a number of times. Its most effective if you install larger injectors and then pull 20%+ fuel with the SAFC. This is the way my car was set up before I had a Dynoflash and it does work. The gain I got with the flash was down low mostly.
What doesn't make sense is trying to change timing after you've been flashed. That defeats the purpose of a flash.
As far as the timing numbers you saw with a Dynoflash, I think something must be up with your car or your scantool. I'll be logging some timing numbers on my car with a pocketlogger soon and I can post them if you like. I'm finally in the process of installing my FMIC and after I do I'll be fine tuning the SAFC and logging timing to make sure that I'm not getting any detectable knock.

My questions to you is this;
Can you, or one of your hundred guys using this crude method, please post a log?
Please prove to me that this was a fluke and that there is something wrong with the car.

I have a simple logger on a palm like so many others. I've been using it for almost a year on 2g's, Evo's, including my RS and another friends MR. I've never seen or heard of anything like this before.
Please post your logs when you can. Thanks.
