Default Re: 92 Toyota

Can't believe I missed this.

Can you tell me which version of HFS3 do you have? Only the V3 has three flow maps programmed in.

You can increase the jet size by one step. Assuming you are running M50/W50 mix. If you are in the US, you can send the controller to Jeff Howerton to be reflashed.

WL and WH will not allow a full width failsafe because the full "min and max" is set internally to ensure there is always some protection.

By reflashing the controller, you will have a wider working range across the failsafe window.
