hjtrbo Posted May 14, 2022 Share Posted May 14, 2022 (edited) Hey team, just wondering if I could get a sanity check on the included log? The log is from the file "91_In Car_Closed Loop Boost 2.tec" This is my first time switching on closed loop boost control. I followed the guides etc. The control looks okish overall. There are 2 spots that I have since adjusted. The first spot is the initial transition from underboost to closed loop. I have softened up the target boost and dropped the duty cycle a bit to try and get a ramp in as opposed to the light switch like action that I have in that log. Hoping that will avoid the initial boost spike I get. The 2nd spot is the large correction around 5000rpm. I added a bit more to the duty cycle in that area. Started raining so will check again next time I go out for a run. The file labelled "92_Ready to load.tec" is the adjustments I made to address the 2 spots noted here. Interesting to get 100% duty cycle up top. I did not expect that. Have bought some plumbing fittings to do a boost leak test on the pipe work. Turbo is also starting to blow a bit of smoke so time for a new cartridge. 98 fuel, wideband matching nicely, FG Mk1 XR6T, F6 turbo. Turbosmart actuator with 12psi spring. Boost target is 17.5psi. Butt dyno got 370rwkw (no correction) not bad considering the air wasn't the greatest today. Still need to get those knock ears on.... 92_Ready to Load.tec 91_In Car_Closed Loop Boost 2.tec 91b.teclog Master List.tlo Edited May 14, 2022 by hjtrbo added screen shot to save opening log 1 Quote Link to comment Share on other sites More sharing options...
