OK, I uploaded a new tune today based on lean cruse/increased ignition timing. Results are very positive. 24.2 MPG before and 26.3 now. Indicated by onboard AVG fuel over a 100 mile city/hwy course. I will gather more data during the week and then post the ROM for referance.
Car runs just as before during accel, during lean cruse conditions the new map pulls fuel and adds timing.
Other changed made are
Removed top speed limit, I have no idea why but I did
Disabled codes to aft O2 sensors
Raised Redline to 7800 and the fuel cut restore points as well
