Hi there, I have tuned 8 of these cars so far, all fg models and 1 ba. Contrary to popular techniques I always tune in closed loop then back fill the wgdc table from the logged wgdc. This takes longer, but I have had good success with it so far. Until now lol. This is my personal car fg mk1 F6 525 pump id1050x pirotta flex fuel, GTX3582, 45mm external gate off housing. 3.5 xforce. I haven't done springs yet which is why I have the boost tapering off at high rpm. The issue I am having is I have a boost error of 1 to 1.5 psi. I am currently commanding 20psi. (boost by gear). This error was worse (2.5psi) I then upped the wgdc from 0.55 to 0.7 which is in the file now. This helped a lot but I noticed in the log that the closed loop is only commanding 0.4 wgdc roughly. I made the hysteresis smaller so it tryed harder to get to 20psi which didn't help. I have upped the gain 30 percent which didn't help so I put it back. I thought about putting 0.72 in the lower wgdc cells to see if it would get to 20psi but I would like to know why the logged dc is way below my initial DC in WGDC table. I made sure I did both petrol and E85 tables as well so it wasn't an interpolation issue. I can put this in Open Loop and do it that way but I thought id see what you guys think.

To disable LTFT when you have no O2 sensor or require it disabled due to large camshafts etc set the following 3 parameters. Set auF0165 LTFT Learning Max to 1.0 Set auF0166 LTFT Learning Min to 0.0 Set auF0170 LTFT Learning TPS Max to 0 counts Old method (does not work for all vehicles). auF0164 LTFT Enable should be all that is required to disable closed loop permanently. Set auF0163 to 4096 degrees. This will mean the O2 sensor is never "up to temp" and hence the O2 logic remains disabled. Or set the delay time to 1000000000 (this is actually clock ticks and not seconds) Or set auF0162 to 1000000000 for all temperatures. UPDATE: on FGs the best way is to just set the A/D Count to 0.0 on the Open Loop TPS Transition table auF0153 as the above tables have been reported to not work on FGs
