Fg Xr6 Turbo After Tuning Problem, Zf Auto Refuse To Kick Down 6Th Gea

[mike0819]

mine is an 2010 fg xr6 turbo zf 6 speed down 44k now, it had tune and injector making about 286rkw, I notice 2 major problem, one is that it keep stall below 500rpm and turn it self off, which a member state I should get an sct tune instead of just load the program, the other problem I notice is that the 6 speed zf sometime refuse to kick down on highway, say I'm doing 100km , it just stay in 6th gear with no kick down or boost, could that be also to do with tuning computer? or is it simple my transmition problem? mine zf shift very smooth most time, really confusing, anyway going to take the car back to my tuner next week for a retuning, any advice I should let him know about the zf refuse to kcck down 6th gear?

Yup I'm hearing you,every time I get a tune the tranny shifts different and my tuner swears he didn't touch the tranny,I do have a sct tune.

when the car is flashed any learnt data will be lost so it is not uncommon for a trans to feel different
