Many thanks. In hindsight, my interpretation of OL has probably been wrong all along. I'll look for the thread on cold starting E38s>

On the E38 LTFT's will Richen and LEAN OUT the mixture in "PE" mode.
Same with the E67, it will richen or enlean in PE depending on LTFT's. I have logged with the fuel trims going both ways, depends on where the LTFT's are when the ECM enters PE mode.
