Robos F6 Donating Members 407 Member For: 16y 2m 7d Gender: Male Location: Vic Posted 14/08/09 04:38 AM Share Posted 14/08/09 04:38 AM I bought my BF F6 knowing the ZF is a great box, but after doing a few 0-100 tests, I am convinced mine doesnt shift as it should be under full throttle. It slurs between 1-2 change resulting on slow 6.0 0-100. This is in both normal and performance mode. As I have never been in another car with the ZF box, is this normal under full throttle???I have just discovered in manual mode, it shifts quite crisp, chirping the back tyres and a little sideways action. I havent tried 0-100 yet in this mode but im sure it would be quicker. Link to comment https://www.fordxr6turbo.com/forum/topic/60633-zf-shifting/ Share on other sites More sharing options...

Not many know how to get on top of it and if they do know the answer, they keep it to them self.Solution = Drive it in manual mode! More fun anyway.Ive heard this problem has something to do with torque settings in the ZF box. With mine making over 900rwNm, I dont think I want to play around with the torque settings and shorten the life of the box before it gets rebuilt.qik1 may be able to offer some advice as he's having / had his ZF rebuilt already.

Born and Bred in the RSA Posted 26/08/09 10:26 AM Share Posted 26/08/09 10:26 AM Hey question can a custom tune cause the ZF to play up?e.g cause irratic changes,harsh changes etc?

gregor Member 459 Member For: 16y 8m 18d Posted 26/08/09 10:22 PM Share Posted 26/08/09 10:22 PM pretty sure an edit can adjust line pressures and firm up the ZF if needed.
