john Venables-kyrke Posted September 30, 2013 Report Share Posted September 30, 2013 Hi there, I'm having a bit of trouble with the boost control on my V7 WRX. Its fine in fourth gear, holds well and is smooth. but in third gear, it fluxuates badly. I've tried adjusting wastegate duty, and and adjusting the turbo dynamics, but I'm a bit lost. I've attached a log in fourth and one in third. cheers  fourthgear.llgthirdgear.llg Quote Link to comment Share on other sites More sharing options...

Kelly Gordon Posted October 6, 2013 Report Share Posted October 6, 2013 Are you getting a lot of P,I, or D closed loop boost correction in third? If so you should probably start you gear boost trim so you only effect the WGDC for 3 gear if all others are fine.

john Venables-kyrke Posted October 7, 2013 Author Report Share Posted October 7, 2013 Ok, I'll give it a try. I've just calibrated all the gears yesterday, as it happens. So I'll try that. Quote Link to comment Share on other sites More sharing options...
