yeah i heard the xi is a pita to install..as if the regular ones arent hard enough lol on jackstands

I'm going to try setting Start Boost in % to 25% with autotune off. That should be the 12.5psi like I originally wanted. Once I see those logs, I will continue to lower it bit by bit....ughh....need meth injection now! haha

Yeah....luckily my dad is getting a four post lift that he is going to let me use whenever....but still doesn't help lowering the subframe.

[chrisw335i]

yeah u can always try it however you want..but if you do that make sure you raise your max boost to 13..remember..max boost always must be slightly higher than start boost..but your previous logs indicate to me that 12 psi is still too high

Yeah I understand that now...I just didn't quite understand how the lower value was calculated and used. All good now! And yes, I too think that 12psi is unfortunately too high still...but just for comparison and better control.

[chrisw335i]

youll most likely benefit most from lowering start boost to 11 and max to 12..it will give you better timing advance and should stop dropping out... which feels much better than adding boost...also safer on the engine as well..timing drops are bad..something you dont want to see

Ok, so I've been trying to look through some of the logs that Shiv has posted to compare them to mine. What exactly am I supposed to be looking for in the "Actual ign advance" graph? (that is the right one right?) I'm just trying to gain a better understanding of what a proper ignition timing graph should look like.

[chrisw335i]

yeah "can actual ignition advance"...not only is yours quite low and has drop outs..under wot and full boost most of us are reaching 10-11 degrees of advance and yours is staying relatively lower..between 7-9 degrees..if you look at the line of the graph for this..look closely at the dropouts..it small dips in the line..some were small and there was a few large one..this is the dme reacting to knock in the combustion chamber..too much boost with your setup is causing knock events aka timing drops

[chrisw335i]

that line should be solid and steady..flat across the rpm range..as you see in your logs that the higher your boost..the more drops you have

Perfect explanation...I see it now and know what to look for. I'm almost certain I can slightly feels those during the pull too.

[chrisw335i]

cool...glad to be of help..once you learn how to read the logs you can really figure out lots of issues in the future..you will get to the point where u can see a log and notice the problem.. it sticks out like a sore thumb..and make the proper adjustments..once you get that timing higher..you will notice it for sure..the engine will feel so much more solid and pull harder

I like the sound of that! haha....and I thought it already pulled hard?! wow...cant even imagine meth


Edit: ...yeahh...timing drops definitely stand out now. Thanks!

[chrisw335i]

once you put meth on..it will be like adding another procede..youll be able to run 15-16 psi and max timing safely..will be absolutely amazing

Mix e85 w/91 to yield e30, you'll notice tremendous results. Ignore speculation about mixtures under 40%. Night and day difference.

IF I decide to run ethanol, we have pumps that offer E30 premixed. South Dakota

I just filled up with e30 premix at a station in central MN, but I wonder what the base is? 87 or 89?
