Timing Map Explanation?

Modifying timing does slightly affect the AFR, but not by much. If you dial in the AFR then tune the timing, you will only need to make minor tweaks to the AFR to get it back in line ... if any.
My suggestion for tuning a boosted lancer is to first apply the modified MAF Scaling settings so that you don't run out of fuel up top. Then, rescale the fuel and timing maps to 110 load. Next, pull about 8º of timing from 80 to 110 load before you do a single pull. That should keep you from seeing knock. Pull more if needed. Set the boost, dial in the fuel and then the timing and that's it.

Beautifully stated, TB!

That old school crap that"make her knock then pull it back" is that just crap. Example. let say that At peak torque you have 6deg of timing. then you give it some more to see what happens, then nothing, so you keep giving it more untill she knock like around 12deg. now you pull her back a notch....ok! thats fine, but she stop making power at 8deg of timing..... so why would you wanna give her all that if she dont need it. you want that cushion. THE ONLY WAY YOU CAN SEE THIS ON A DYNO...
And as fragile as our motors can be, that cushion is MORE than welcomed!

Lets keep going with tuning info tips and tricks. I like where this is going. A lot of good info in just three pages. BTW, is there a good writeup yet on how to use evoscan by chance? How to take full advantage of all its features?

You will most likely not ever reach MBT (Minimum Best Torque ... where more timing yields no more power) on pump gas, so it is perfectly logical to add timing until you encounter knock and then pull back a couple of degrees.
If you are on C16, E85 or similar then you do need a way to monitor torque output as you may reach MBT. You don't need a dyno for this. You can use a software application such as Data Log Lab for this assuming your pulls are consistently in the same place on the street.

From what I understand, same concept, little less work. Am I right? I was asking senate questions about tuning awhile back, and basically, from gathering info from him, this thread, and others ive read, first thing you want to do before even messing with your fuel maps is eliminate knock using your timing maps. Then you use your fuel maps to achieve your desired A/F ratio, while keeping an eye on your vitals of course, then you go back into your timing again and advance your timing till you see knock, then back it off 2-3 degrees for cushion. I dunno if that makes sense, and you guys can correct me if Im wrong about anything (which I hope you do as im always up for knowledge), but thats kinda how I am understanding the "basics" of tuning.

Also you already have your base map from the factory for na tune. Dont have to worry about rescaling anything either I would imagine

Sounds right to me lancerman, its the same concept reduce knock, lean out afr's. Except with n/a you can lean the fuel out even more since you dont have a crapload of air being forced into the combustion chambers. Also what I have heard is in general the higher loads you hit the more power you are putting out??

Just remember this. AFR will not make you any "Significant" power. Timing will make your "real" power. Your AFR are nothing but "Thermal Management" Use your fuel to keep things cool...... later~!

Step one. make sure you retard the crap out of her when you start this prosses. specially when youre taking away fuel
U folow?

I definitely follow. Im glad to see that no one has corrected anything Ive said yet so maybe Ive got a good understanding of the basics. Still watching those vids 03 posted. Any other tips for tuning?
