Hi guys,

Just wondering how we go about enabling table switching on the new V3 firmware. From what I can find in the Tables Switching menu, VE doesn’t have a flex fuel option. Is there a new way to set this up? Or is it a feature still being developed? Below is a screenshot.

Thanks all!

For what ? The VE table (volume of air sucked in by the engine) does not need to be changed based on fuel type or injector size. This is useful for switching tables if you have a VTEC system for example.

Injection times are calculated automatically based on ethanol content

I’m talking about blending for flex fuel, depending on the ethanol content of the fuel, for the ECU to blend between the maps. Is that not done through table switching?

Also you can alter the ethanol correction table as the fuel composition can differ in different countries.

Don’t know how I missed that, thank you very much 🙂
