[QUOTE="SpartanDieselTech, post: 1284496, member: 22311"] Your excessive regens are coming from the changes in lambda. You should try returning it to stock. Even though 1.01 should be perfect stoich, it isn't. Ford has the lambda tables lean at cruise to introduce excess oxygen into the aftertreament system. This excess oxygen helps keep the system in a constant state of mild passive regeneration, making intervals between regen longer. It also helps de-NOx the SCR media. Think of it this way - regeneration is burning off excess soot. In order to burn something, you need extra oxygen. At 1.01 air/fuel, there is none, so passive regeneration ceases to happen. Return all the injection duration and lambda back to stock. If you want an increase in fueling, use the torque-to-fuel quantity conversion table. At any points you change, change the desired MAP turbo controls and turbo feed forwards to a matching percentage increase. Then, play around with injection pressure. Once you have that where you want it, make minor increases in timing. Don't get crazy, too much will drink DEF like a fish, and more past that will throw errors for NOx thresholds high/SCR system performance. [/QUOTE]
