Cold weather has officially set in up here in the Great White North, which is giving my car fits on cold starts with E85 blends. Following off of SAE research presented in 2009-01-0620, approximately 3x the amount of fuel injected during a cold start is necessary when using E85 versus gasoline to compensate for the vapor pressure differential in cold weather.
Seeing as the Fuel Open Loop tables are not yet defined in ATR or any of the XDFs I've seen for TunerPro, it appears we're currently sitting at a dead end with respect to fixing this issue with a DME flash until Cobb or someone with major WinOLS skills can crack the table. I can't imagine I'm the only person driving a N54 in cold climates with an E85 blend so the question becomes, what other solutions have been brought to the table to fix this issue?
