Hi, can someone help me with optimising the Transmission of my 2017 Charger? Attached is the original data. Looking forward to your reply. Thanks! Karoly

Hello!

Definitely I can support you! But, first:
- Which issues are you having?
- Which improvements are you expecting to have?
- What is the use of the vehicle?
- Do you have a log?

Thanks.

Hi DodgeBoy,
i dont have specific issues i just would like to optimise and imporve it (e.g. higher rpm). I dont know about the options, therefore i asked for help.
Iam using the car in normal workdays, no extra specification.
I have a log, attached, if you mean that under "log". if not, i dont have any others.

thanks for your support in advance.

Hello!

It is possible to, on transmission side:
- Increase RPM (shift point)
- Decrease slip on torque converter
- Shift pressure (quicker shift)
- Torque management

It is possible to, on engine side (in case you are planning on tune engine as well)
- Torque management
- Airflow
- timing
- Drivers demand
- DFCO

Thanks.

Why do you want the car to shift at higher RPMs on a stock cam?

Why do you want the car to shift at higher RPMs on a stock cam?

fun factor and due to the fact that the stock 5.7 cam max shift rpm is just under 5500. I would stay around 5800, torque starts to drop off after that.
Additionally, raising the shift rpm just isn't about that max rpm it also about landing the next gear in a more optimal rpm range if available.

I am working on a stock 5.7L.
Just adjusting the point I mentioned above, it was possible to increase torque, horse power and shift timing. So, only via software/tune it is possible to have a better powertrain behavior.
