I recently put a HDC 450 in and I am running lean. I also just got a D&M and need some help. What do most 450's run at as far as flowrate and do I also have to adjust the offset?
Ok to richen the flow rate you will need to go down in 50 increments. like if it is 2500 go to 2450. Now you should redo the I/O and TPS while you are at it. There really is no fixed # to just plug in.
When you start the program you should recieve settings first. Use that number for flowrate as that is your starting point. Do not repeat do not use 2500 as a base number unless that is what you recieve from your ecu.
