In Gear Target Table
This sets the target Line Pressure when the Transmission Control function is holding the transmission in gear.
If there is a base map available for your transmission, it is recommended to import the Target Pressure tables from there.
If the transmission you're using has been rebuilt with upgraded components, ask your transmission builder what changes you should make to your target line pressures.
If there isn't a base map available, the best thing to do is copy information from an already tuned vehicle using the same transmission. You may be able to find some information from OEM service manuals as to what pressures are used.
If you don't have access to any sources of information, you can use base maps for other transmissions as a starting point. This approach can cause problems, such as excessive wear and/or harsh shifts, but it's better than guessing.
If possible, start with the most relevant base map.
- Start with a higher line pressure and work backwards until the shifts feel less harsh.
- If you get slippage in the transmission while in gear, increase line pressure.
- More engine torque requires more line pressure.
