WRteXan Posted November 28, 2011 Share Posted November 28, 2011 I know, this is probably the noobiest question ever. The LGT is my first auto subaru, so I'm not sure how to make a good clean pull like I do with a MT. If I want to make a dyno pull, or a WOT boost tuning pull, or even rescale my MAF (I have a Cobb CAI just screaming 'install me.') On my WRX, I make all pulls from 4th or 5th gear, so I just put it in that gear, slow down to 2000-2500RPM and go WOT to redline. How is this accomplished with the auto?

bmx045 Posted November 28, 2011 Share Posted November 28, 2011 switch the shifter in manual mode, get into 3rd gear to about 2k rpms, floor it till redline. done. you'll see a torque converter spike in the plot up until about 3800rpm(not real power reading), in which the tc then locks up and power gets directly transfered to the drivetrain. The plot after the tc spike is real time. There are some dynos that can factor this spike out, but road tuning and logging, it will be there.

bmx045 Posted November 28, 2011 Share Posted November 28, 2011 A way around this is, in romraider dyno tool, I chose to start reading the pull at about 3800 rpm - redline when flooring it from 2k rpm. It filters out the spike and seems to be realistic. Link to comment Share on other sites More sharing options...
WRteXan Posted November 28, 2011 Author Share Posted November 28, 2011 Thanks. I thought the TCU would kick down even in manual mode, but I'll give it a try tonight. Doesn't the dyno tool recommend using speed instead of RPM for the autos? I use the airboy spreadsheet and his has an auto selection. It was originally only for a 4EAT, but a few quick changes and voila! Link to comment Share on other sites More sharing options...
bmx045 Posted November 28, 2011 Share Posted November 28, 2011 use virtual dyno, they have our car in there with the correct ratios. Link to comment Share on other sites More sharing options...
