- read your calibration file (aka bin file) from your existing chip using the burn2 or whatever chip programmer you buy. alternatively, download a copy of your original factory bin file from the internets.
- load your definition file (xdf) into tunerpro, so tunerpro understands how your calibration (bin) is layed out
- load your calibration file (aka bin file) into tunerpro
- make changes to the bin with tunerpro, in your case, something like minimum rpm to enable egr = 7000 or something so the egr is never actually used would make sense.... and save. the changes you can make and how easy they are to manage depend on how good your xdf (definition file) is
- erase the chip and write the updated bin back to it, throw it in your car, and away you go
That clarifies it all for me, thanks a bunch!
