Help with log max out wastegate and fuelpump
Little background:
mods that matter: 02 wrx cobb stg2 ported/coated - header, up pipe(erz), turbo, throttle body, downpipe(erz) turbo inlet hose so since i got all of my porting and coating done that i wanted to do on my car i decided i should take some logs of stuff because i am much free'r flowing. Well did it today and found some interesting numbers. Boost definitely coming on alot sooner like i had thought, however my wastegate duty cyle gets max'd out and so does my fuel pump. I have tightend my wastegate arm a few times so i could reach target boost. Any input would be great. 4th gear log Code:

First of all, your fuel pump is not maxed out. The "Duty Cycle" on the FuelPump column is SUPPOSED to go to 100% when you hit WOT. It's just how it operates. That doesn't mean it is flowing its maximum flow.
Secondly, you are logging a few things that you don't need to. Obviously, there's no point in logging the FuelPump as it will always go to 100% at WOT and you'd only ever need to log it if you suspect the controller for it is broken. The AFR is not at all accurate (not even close) so you shouldn't bother to log it. It just slows the logger down. Same with EGT - that won't tell you anything useful as it's way too far downstream to be meaningful. Also, MPH won't really tell you anything unless you're trying to put this data into some kind of road-dyno spreadsheet that uses vehicle speed to approximate wind drag. And finally, in regards to the WGDC being maxed out for that short period of time, it's because the mapping actually calls for 17-16.5 psi of boost starting as low as 2300rpm and it also gives it a starting point of 96% to help achieve it. You will never get the turbo to hit 17psi at 2300rpm so the "correction" table will also come into play, adding another 5-10% to the already high WGDC. The result is maxed out WGDC. Don't bother tightening your arm any more - you'll just overstress the diaphragm and cause it to fail. Your log looks healthy. It's giving the full mapped Dynamic advance all the way through your log so that would suggest that you're not getting any knock there. If anything, I'd check that you don't have any leaks before the turbo. |
