Change gear and RPM ?
 

Anyone that have tested an accelerometer to get information when to
change gear on right rpm on our engine, like Gtech or another g-force meter ?

There are several plugins for Torque Pro (android) that can provide a graphical output. See Plugins - Torque OBD2 Wiki


Since I bought Torque, I have not used my G-Tech Pro. The cell phone is more accurate.


HMMMM $20 vs $180. Tough choice.


Now what I want is a 2.7 axle.

2,7 axle ?
If you mean the differential in the end of the car, i want 3,73. And you find it in a
ML320 2001. That next step.I fits our car. The Problem is the TCU

No I meant about a 2.70:1 axle ratio. Right now I start in 2nd and am turning 2600 rpm at 70 where it should be under 2k. Thought the point of having a 6 speed was to have a looong overdrive for cruising and not a super granny 1st.


3.73 would only be useful with an automatic and slicks.
