so fairly new to the tuning scene and was wondering about the timing tables and basicallly if theres any improvements that can be done to pick up power?

All depends on the how high of an octane you are willing to run. Attached is a stock tune and 93 octane canned tuned for a 5.7 for you to compare.
2015 challenger RT M6 stock (converted-original).hpt
diablo 93.hpt
so with more octane i could run less negative timing?
Negative timing is a result of your base spark minimums and tq reduction tables.. i would do lots of research before making any adjustments
Also your part throttle spark table... but theres so much math and science to tuning. Shouldn't just make changes if you don't understand it as a whole.
So are you saying pro tuners are using math to calculate max timing?Originally Posted by luciddeath
Im just saying that this guy says he is new to tuning and might want to be sure he knows what he is doing before he goes playing with the vehicle boss, lol
I don't do this for a living and your comment had me thinking pros might now be using some type of software to help set-up initial timing maps along with rules of thumb and experience?
OP if you are new to tuning then books from Greg Banish are a great start but the fundamentals are only half the battle. Using HP tuners and knowing what table to modify for desired changes is the other half. There are a lot of great threads here posted by knowledgeable tuners well versed in tuning Dodge vehicles that are very helpful as well. Here are some I found useful.

If you are a total noob and have the budget for it, taking a beginners course (hands on classes seems to be more beneficial) in Dodge tuning offered by the Tuning School can help bring you up to speed quickly.

Also comparing tunes from various threads and/or the tuning repository is another great source of learning. For example the tune files I attached earlier were from the same vehicle with one tune being stock tune and the other a tune modified by a Diablo Sport to run 93 octane.
As for the comment about running less negative timing...if you look at a stock tune you will see most base timing is positive and in general running high octane means more timing advance can potentially be applied as the flame speed is slower. Here is a nice article about ignition timing from Engine Builder Mag that gives some background.

Good luck!

i know that one wrong change can be dangerous thats why im trying to get info i can to try and understand what all the numbers mean and how it changes the way the car runs. Thank you for looking out guys.

This should get you started into understanding how the platform and hp tuners works. Hang around and read everything you can on this and you be surprised how much information is already available.
