Not *yet*. But I've been in communication about thatDo you know if COBB works with European cars?
Yep, it doesn't do much. Even the cooling effects taper off as well above 70%.Great work! Not surprised about the e90. Anything over pump e85 is a waste on my CTS-V (and that's with ID1300's). Ethanol at the pump measured anywhere from low 60% to 76% depending on the season (winter vs summer blend).
I think eventually I want to run e85 strait from the pump without mixing, other than the occasional 93 octane to flush it out every once in a while, just like I do the V.
