Plenty of you have helped already but I have more questions to make sure I am doing the right thing.

I went into my High octane spark table. I highlighted all of them and added 2. In my most recent log I didn't see any knock retard under excell. I realize there is a chance that 2 degrees could be too much but if it doesn't cause any KR that will add 2 degrese of timing under normal driving and full throttle runs correct.

Not sure if it will show up correctly but if you can tell what is my "max" advance? Thanks again I know this is time consuming for my self and you guys helping me out especialy.

Also I have a Wideband. I know hooking it up will help in the tuning. But once I get it hooked up. Will I turn the inject timing down a tiny bit at a time to lean it out? Are the timing and fuel curves as simple as I am starting to think? Or are there supporting changes that are critical to timing and adjusting AF ratios?

Well looking through my log again it looks like it was pulling timing at full throttle. So seems like no need to add timing. Should I pull a degree or two or should I just start running mid grade? This was in fairly cool air, 50* or so.

When Justin did the tune for me I told him economy was the biggest issue. I have seen plenty of guys claim to get an extra MPG from running there mid grade fuel tune. Justin's answer for the tune he gave me, was run a few tanks of regular and run a few tanks of mid grade and see what is best. I honestly have only ran one tank of mid grade since the tune. Looking at that log I should pull a some timing or start running mid grade and see how the log looks then.

There is no way to know your max advance from looking at that table, 1st off there are many tables that come into play to determine total advance, 2nd your post just showed up as a bunch of numbers. As it has already been pointed out, you need to do more reading. Don't get carried away, you shouldn't get crazy until you understand how the table works and what other tables come into play as well. You are not going to learn to tune in a half dozen threads and 2 wks of reading.

I have done some reading occationaly over the past 6-8 months. Reading and having an idea becomes scary when you are considering adjusting stuff!

Post a screenshot of the tables if you can. As mentioned it doesn't show up the same the way its posted.

Without a log of the changes, it is hard to see what is going.

You mentioned having an Economy tune. Is that Why it's pulling timing, is it leaning out??? Does it need more fuel or possibly a higher grade of fuel???

To the Other Person, Custm2500 is using EFI Live software.

How do I take a screen shot? I can't find volume down and power button on this computer like my phone.

I know I have to make changes, go log then re adjust.


I had him tune more for ecconemy. Like i said I had seen plenty of people claim betted ecconemy with an 91 tune vs. there 89 tune. So I had him tune what he felt was best. his answer on what fuel to run was try both and see what works better. Turns out is is pulling timing when going 100% throttle once it is warm, at almost anything below 100% it never pulls timing.

So maybe I don't need to adjust timing but when I plan to drag race I should make sure to atleast run 91? Then obviously data log.
