    My Cobb datalog

    Here is a datalog of the car on stage 1+ fmic. I feel like I might have a boost leak, I did a datalog but I can't figure out how to graph it using the template. Can someone do it for me?(uploaded csv as a zip)

    Here ya go.

    Looks like you are a little short on hitting your requested boost up top, but you're not too far off. Your timing is getting yanked post shift pretty bad. I suggest throwing in a can of octane booster or E85 and relogging to see if those timing corrections improve. Which map are you running? (Agg, sport?)

    Thank you! 91oct on the sport map.. Could it be boost leak related??

    Maybe a slight boost leak, but I doubt it. How many miles on your turbos? Looks more look like loose wastegates to me.

    Add MAF requested (WGDC) to your logs and boost set point factor and take some new logs. I can help you dial things in to hit targets, but another thing to consider is that based on the timing pull post shift, it might be too aggressive of a map. Is your ROM type I8AOS or IJEOS?

    Also, did you ever put the downpipes back on?

    ROM is I8AOS.. I will take a new log later today or tomorrow on less aggressive drive map. Sold the dp's and got a fmic instead (emissions/warranty work would be a hassle) My SA does not care about the fmic but If I ever had to get the turbos replaced dp's would void my 100k mile warranty so I'll have to wait but once this things goes over 100k I want to go all out.

    Log was kinda short and I had to shift a bit early. It looks like my timing still being pulled post shift?

    You had a few timing drop outs during the pull but it appears fairly normal. Timing post shift looks fine, granted you didn't stay in it for very long. Overall it looks healthy imo, and you are hitting your boost targets just fine. Click here to enlarge
