Adamw Posted May 19, 2020 Report Share Posted May 19, 2020 Drop your idle proportional down to 1.0 and your anti stall gain down to about 2.5. Let us know if that settles it. Quote Link to comment Share on other sites More sharing options...
Christopher Kafkalias Posted May 21, 2020 Author Report Share Posted May 21, 2020 thank you Adam,done the changes and it seems to working ok now. other thing after upgrade is that when i store to ECU it says ''store failed'' but it actually stores-saves the changes made. any way i can fix this?

Adamw Posted May 21, 2020 Report Share Posted May 21, 2020 Are you maybe using an extension cable on the USB? Store issues usually mean you have a comms problem. Quote Link to comment Share on other sites More sharing options...
