RomRaider is used for editing. It is not required for flashing.

Defintions are prioritised from first to last.
Selecting any table in the list will compare the table from the first rom to that of the second.
Example - OTS Stg1 total timing compared to stock MY12-16 total timing:
All graphs from the same dyno, same day (2015-07-18), same 20C intake air temp.
These are very old roms with original injector ratios, however still indicative.
Each vendor has their own instructions, videos, etc.
On the RHD Moto East kit you can mount the sensor in such a way as to not bend any of the lines.
DO NOT attempt to mount the sensor over near the brake lines or strut tower, where you need to bend the fuel lines back on themselves.
With my files, you should attach the sensor to the DIRECT INJECTOR line as the car uses 100% DI at idle as per stock.
Cut a hole/slot in the firewall grommet above the engine loom for the sensor to ECA loom.
The most difficult part of the install is getting at the ECU, particularly for RHD where there is an extra control module in the way.
You can either remove the EVAP pin from the ECU plug and re-pin it, or Moto East sells a harness which goes between the ECU loom and the ECU.
Moto East provide a piggyback for the fuse box to provide power to the Ethanol Content Analyzer, mounted behind the dash in front of the drivers knees.
The gauge tells you if the ECA has power and is outputting a signal. It won't tell you if the signal is reaching the ECU, you need to log for that.
