how does this look?

 

Can someone explain the datalog shown. It'll be of use to those of us trying to learn. Thanks.

 

I take it the rpm are varying because this is a multiple gear pull. Try doing just a 3rd gear pull from low rpm all the way to redline. Looks like it still needs some work in the timing and the fuel. What are you tuning with?
You need a wideband

 

with a pocketlogger.. I'm kinda new at the tuning thing and just trying to figure it all out right now.. so i should do a 3rd gear pull from low rpm to redline right?

 

yeah do a 3rd gear pull and log that. usually i go from 2000-7300. just to let u know on ur log that u have right now, ur running pretty dam rich with ur o2 at .94-.96 throughout. u want to bring it down to around .91-.93 dependining on how safe/aggresive the tune is and on ur driving conditions. and it looks like ur timming is all messed up. u want the timing to climb and peak without dropping at certain RPMs. im still kinda new to this stuff so if im wrong in anything a guru can correct me!

 

i expected to be rich.. since i just put in a 255 fuel pump to go with the 272 cams that recently went in.. basically i'm just trying to figure out the pocketlogger and how to read all the data then i plan on getting a safcII and having a friend help me tune alittle...

 

what kind of ecu upgrade you guys think i should get for my 03 evo8

 

ok I went out today and did 3rd gear... looks like engine isn't as rich as before but what about the timing....

 

^^^^^

 

what mods do you have, I have a pocketlogger too and am learning to read the parameters. I will do a 3rd gear pull today too and we can compare numbers...

 

your log looks pretty good. the only spots i would try to improve on is from 3400-4400 rpm. you should try coming into peak tourqe at around .96v and see if that keeps your timing above 5. i would add +2 at 3445rpm and +1 all the way to 4434rpm. repost the log so we can check it out after you change it .

 

I agree with adding fuel so you can up the timing.You want the most timing possible without knock.
