Hi,
I am french, sorry for my english...
http://www.the370z.com/engine-drivet...ar-review.html
The 7 automatic 370z gearbox have "downshift rev matching" - DRM , it permit synchro between engine and gear box during downshift.
you change the final drive (9,97% --> 47/14 to 48/13).
your pumpkin is from a 2009 370z manual transmission.
on the pumpkin, there are 2 sensors for ABS and speed.
on 350z there are 46 teeth for ABS.
on 370z there are 48 teeth for ABS.
from i understand, you have the thoots number needed, and respect needed for 370z ABS.
the only problem can come from final drive (9,97% --> 47/14 to 48/13).
Does "downshift rev matching" function change or run or not?
any problem, impact or not ?
all is ok to 7500 rpm for change gear?
do you make ecu reflash for solve "downshift rev matching" problem ?
at how many prm, what RPM value it not run?
what happen?
Else, all is ok..
Thanks
Best regards
Xavier
