H6 acceleration problem

Postby Worx774 » Mon Sep 30, 2013 2:33 pm

Hi guys

Have just upgraded from the 3.0 auto to a black b-spec manual and have noticed that both cars were sluggish between 1.5-3.5k rpm. But the manual in that range whilst slowly accelerating is jolting a bit.

Anyone have any ideas or had same problem?

as above,

98RON minimum

you'l;l notice that it settles after a bit of driving as teh ECU learns how much timing it has to pull.
my car is always a pig after an ECU reset.

Just waiting on a tune to arrive to cure that :D

The manual boxes in the H6 can be pretty rough down low. Its just the way they are. You'll get used to it- try keeping it around 3k and not dropping the clutch too quickly after changes with low RPM- it'll be a lot smoother
