So with the N54 its as easy as Mixing E95 and 95Pump gas,,,,Select Map 3(if you have water/meth) or 5 on the JB4 with G5 board. That`s it finish and klaar.

Does the E95 not have its own natural cooling effect on the engine?

Correct on both accounts. And monitor LPFP activity (in the oil gauge hi-jack) if you choose a high ethanol concentration.

How long did it take to overcome the cold start issues, and will each car have to be set up/tuned individually to run ethanol?

Cold start issues were resolved by adding more pump fuel or diluting the ethanol content. In other words just lesson the ethanol percentage and the cold start will be gone in a day or two.

Or you can opt for the BMS flash tune combined with the JB4 and this will prevent the cold starts all together when using a higher ethanol content.

Twinz, you should've have been a motoring journalist, your approach to the way you write your articles is incredible. I have yet to see someone on this forum take this much time to write such well thought out and articulated articles in laymans terms that everyone can understand .

Thanks for the nice compliment...my head just swelled twice its size...:=):

It's recommended to do the ISO mod to the G5 JB4 board for ethanol.

ISO is not required for running ethanol. G5 integrated will do. If you have an N55 with flex sensor DONT go the ISO route... wait till the ISO tuning has stabilised...perhaps by mid 2013.
N55 guys you have been warned. There are still too many bugs to "isolate"...excuse the pun.

I assume you have the N54 motor? If yes, then start with a 40% ethanol mix. In other words: 7 Liters ethanol & 13 Liters pump. Then work your way up from there...the car will get stronger as you increase the mix. But just take it easy, allowing the car to adapt to the new mix.
