fuel system status
intake air temperature
maf voltage
that way we can filter out all the crap data and plot something useful to look at. if you want to send me your maf scaling (if it isn't just stock) then i can send you back corrections to apply as well.
or you could just watch my screencast here and do it yourself.
you can ignore all the bits about process separation and port/di ratios. that doesn't apply to anyone who isn't either completely anal or having aftermarket injectors. if you wanted to dial in di and port independently you could however, though it's pretty difficult without custom maps. you'd have to create two logs, one with di only and the other with port only, and then log the injection mode param to filter on. the great @ mad_sb made a thread just recently on the topic for the OFT/open source guys. my method of doing the same requires features not available on those platforms, and as such wouldn't be of use. |
This is something I can definitely work on as soon as we get more logging parameters from the OFT. I currently don't have access to intake temp or fuel system status (is that just a 3 state parameter logging DI, PI, and DI/PI combo?).
