What would need to be changed to make this work? I understand EGR type would need to changed to 0 from 2. How would I go about getting it to add more EGR flow?
This is for a mileage experiment I'm trying. I am going to do a back to back comaprison to see what effect EGR has on mileage.
Thanks!!

I am assuming you are using a GUF* ecu here.
You need to set the 'EGR Type' (aka PFEHP) parameter to either 0 or 1 depending on your EGR system fitted as 2 disables the EGR. AFAIK all the GUF* use sonic EGR (setting 0).
The amount of EGR (during non MFA mode) is determined by the 'EGR Sea Level Table' (aka FN9098A) and 'EGR Altitude Table' (aka FN908B) tables together with their ECT and ACT modifiers. To increase the amount of EGR you need to increase the values in these tables.
