Default New fuel that I am playing with...we have a few stations here where I can pump E-30

fuel, it's 95 octane. I've tried it a little tonight with the 93 octane program, seems to run stronger than with the normal 93 I've been using...pulls strong. Anyways, what I want to know, is what can I log with vagcom to make sure everything is working right with the fuel, what should I be looking for? Seems to be a good option, so I want to know if it's going to work. I figured it should, as I have tried E-85 before and it worked fine, and this is only 30% ethanol, but still 95 octane. Thoughts?

Default A/F ratio is affected. Running closed loop (part throttle) your ECU adapts to maintain stoich

During open loop (WOT) your car will run "leaner". The same amount of fuel is delivered at WOT however stoich for E30 is lower than straight gas.
