Hi guys,
does someone konw how to completely disable decel fuel cutoff on this rom?
Decel fuel cut resume only goes to 1992rpm so it is not a viable option.
Thanks

 

Noone?

 

Disabling decel fuel cutoff entirely on your Evo 8's ROM can be a delicate task. Please keep in mind that modifying fuel cutoff settings can have consequences for engine performance and drivability. It's recommended to have a good understanding of the implications before making such changes.

To disable decel fuel cutoff, you would typically need to locate the fuel cutoff maps in your ROM and adjust the values accordingly. These maps control the conditions under which fuel cutoff occurs during deceleration. However, the exact location and structure of these maps can vary between different ROMs and tuning software.

It's crucial to work with a suitable tuning software like ECUFlash and have a thorough understanding of fuel maps and related parameters. This will allow you to modify the appropriate tables in the ROM. If you're not confident in your tuning skills, it's advisable to consult with experienced tuners who have specific knowledge about the Evo 8 and its ROM structure.

Additionally, keep in mind that disabling decel fuel cutoff may affect emissions and could lead to higher fuel consumption during deceleration. Therefore, it's important to consider the implications and potential trade-offs before making such modifications.

Remember to always keep a backup of your original ROM before making any changes, as it allows you to revert back to the original settings if necessary.
