Adamw Posted July 20, 2022 Report Share Posted July 20, 2022 There is a multi-fuel tuning guide in the help file page: G4+ ECU Tuning Functions > Fuel > Multi Fuel > Multi Fuel Setup and Tuning Guide. You need to use modelled fuel equation for flex fuel so the existing fuel tune is no use - you will have to start fresh and tune both fuels from scratch. I have heard of many users having trouble with accel enrichment when using a roots blower with some injectors on top. Im not really sure why. However I would first try changing your Accel enrichment mode to TPS instead of MAP, you will probably find MAP is not a good representation of transient air flow because you have a positive displacement pump always trying to keep MAP constant.
