Boost by Ethanol Table

Post by Semin1907 »

Hello Dears ,

I want to use boost by ethanol table but when i change the values it disables Flex Fuel Support on Mods Section and car goes with main boost airc table.

I want to use with ethanol 0 for lower the boost and over e20 i want to icrease airc.

For example i want to use 0 ethanol airc as 225 and for e20 i want to use 240 airc.

Notes from the modification "Full flex fuel support for existing calibrations. Default air charge limit tables."

If you change the air charge tables then the modification is no longer shown as selected. This does not mean that flex fuel support is disabled.

It gets there. The ECU Air Charge control is not perfect and it your case it lags about 1000 rpm behind the table.
