I was just wondering what some of your autotune settings were and what wideband you guys are using with what delay. I still have a problem with my afr jumping around like crazy and because of it autotune will take some fuel away but then add it right back and doesn't work for me. I also ask your wideband and delay setting because MLV doens't work for shit for me right now and was just wondering if I had the wrong setting in it or something?
Here is my latest MSQ. Please take a look at it and let me know if you guys see anything out of wack in the settings or in the inni files. Remeber to open with MegaTune! Thanks!
Here is a shot from a log where you can see what I am talking about. Yellow is AFR, Teal is TPS, Pink is RPM, Green is Battery Voltage, Red is MAP, White is Pulse Width, Blue is Coolant Temp, and Green on bottom is Duty Cycle.

From looking at your MSQ, your target AF map is all wrong, and that's what AutoTune seeks to. Your step ize and adjustment amounts are probably too high as well. You want AutoTune to make small adjustments.

Well I made the adjustments that you and I talked about Dino and its to no avail It did slow down how fast the GEGO was changing but it can be very lean then blip to a rich spot then it goes back to taking even more fuel out even though its already really lean making bad, worse. I moved the step to 32, I tried it at 64 but it was too slow. I really don't know why its doing it. I tried Vexme tonight after a log on the way home after I figuerd out autotune still wasn't working right, and it just mad a part of the table I don't even use rich as hell and didnt change where I normally tune at(cruising areas). I don't know I am open to more suggestions!

Wideband is about six in. from the cat. I was doing some manual tuning today and got it pretty good and decided to turn ego on and I'll be damned if it didnt start going crazy, afr started jumping around and acting crazy like it did before! What would cause EGO Correction to go so crazy like that?

located at same spot here.
16 msec per step controller step size 2% authority 0% active above 180F active above 9000RPM
Not sure whats up w/ mine. Whats the difference between msec and ign pulse? And why would mine be set at active above 9000RPM? I havent changed anything. Do I need to change some settings?

rundown on EGO: ignpulse vs. msec - rate of change for ego compensation. milliseconds (fixed throughout RPM), or ignition pulses (RPM, basically). controller step size is how much it'll adjust injection pulse per change, authority is how much it will allow it to change TOTAL. Active above: pretty self-explanitory. around 140/160 degrees is fine, and RPM is when you want it to kick in. I have mine at 500, between crank RPM and idle, that way it'll control idle mixture as well. Sometimes this is a pain, and many people have it around 1000/1200.
