[QUOTE="65fastback2+2, post: 12730013, member: 58051"] bingo. if you get tuned on summer e85 or even e98, come winter, your tune only goes slightly richer (usually less than 1/2 point AFR though it could be as much as 1 point AFR). This is less important on ethanol because of all the protection factors. My lightning was tuned to 11.6 AFR. Furthermore, because of oxygenation, ethanol doesnt mind being slightly richer. A YEAR after having my lightning tuned on e85...the entire time not checking ethanol content and driving the thing how it was meant to be, my datalogs showed 21* of timing crossing the line at the drag strip....exactly how it was supposed to. Im not 100% a mechanical genius...but I know how I asked my tuner to set my lightning, I know how I drove it and I know what the datalogs showed and I know how it performed vs. a 93 octane truck with same mods [youtube_browser]vfcUdZbVHa0[/youtube_browser] [youtube_browser]kX0CzoGL15w[/youtube_browser] [/QUOTE]
