Basics of Tuning
- Discuss Ways to Tune and Pros/Cons (eg. Dyno vs Road Tune)
- Brief Overview of Types of Engine Management (eg. Stock ECU w/ Flash, Perf. Chips, Piggybacks, Standalone)
- Basic Tools Needed to Tune via RomRaider (eg. Wideband AFR, Boost Gauge, Software & Interface Cable)
- Advanced Tuning Tools (eg. PLX Loggers, Pre/Post intercooler temp sensors, Performance Meters, etc)
- Basic Tuning Practice Overview (Log, Adjust this & that, Log more, etc)
- Rescaling for Load, How Subaru ECU Interpolates between cells
Relationship Between Boost, Fuel, Timing, EGTs
- Timing and Detonation
- Boost Pressure and Charge Temp, Turbo Inefficiency
- Higher RPM = More Timing Advance
- Tuning for Fast Turbo Spoolup
- Timing Advance vs AFR vs EGTs
- Flame Front & Burn time vs AFR vs RPM
Tuning with RomRaider
# Opening a ROM in RomRaider
Simply click the Open icon or flick ‘File’, then ‘Open Image’.
Then select the file you wish to open.
- or Getting a ROM from your ECU via EcuFlash
# How to Edit Tables/Cells
Select multiple cells by clicking and dragging. Once the desired cells are selected, you can use the increment or
decrement buttons to increase or decrease the selected cells. I find the multiply (‘Mul’ button) feature to be the
most useful of the editing features. It is also possible to set the values of all selected cells the same by using the ‘Set’ function.
# Saving ROMS
Click the ‘Save’ icon (hard drive looking thing) or click ‘File’, then ‘Save ****.hex’.
