David E Posted May 14, 2017 Share Posted May 14, 2017 Looking to have an '09 OBXT dyno tuned and the tuner wants to hold the car in either 3rd or 4th gear, whichever is closest to 1:1 ratio. Anyone know a way to accomplish this? Tuner is used to manuals.. Thanks! Link to comment Share on other sites More sharing options...
njlabodin Posted May 14, 2017 Share Posted May 14, 2017 I would guess just put it in manual mode and stick it in 4th. Link to comment Share on other sites More sharing options...
grovlet Posted May 14, 2017 Share Posted May 14, 2017 Does OBXT have manual mode? In an LGT is actually that simple - manual mode does not have an auto up-shift feature - so it works fine. Not sure on gear ratios on OBXT - but in an LGT it's preferred to use 3rd. Link to comment Share on other sites More sharing options...
David E Posted May 14, 2017 Author Share Posted May 14, 2017 Thanks. He thought it would auto upshift, but will have to check. Link to comment Share on other sites More sharing options...
