Hopefully will be locally getting a more consistent E85 supply soon. The problem is that it is about 10 miles from where I get good 93 fuel. I think the e85 station only has 91 and I dont think the quality is great. I have all of the bolt-ons other than the LPFP and sensor which comparatively speaking are inexpensive so would like to add the last 50 hp with e30 I can get out of the car. Questions; 1. When running a E30 tune can you first get the gas and then drive 10 mi to get E85 to complete the mixing process? My understanding is I have to reflash when going back to gas but will a short drive matter? Will the car even run with the e30 tune on gas? If not would it be better to just use 91 at the e85 station? 2. Does first filling with E85 change the above answer? 3. How much mixing wiggle room is there regarding the percentage? I plan on using a Bluetooth sensor so I hope to not have to keep testing the e85 content in a testing device etc. 4. Winter temperatures here vary anywhere from 30 to 50. Are there any starting issues at freezing temps? 5. I get the sense a lot of you guys use the SHO as a weekend car. I use my minw for business periodically having to meet clients outside the range of any E85 stations. Seems to be a hassle having to flash to a gas tune in these circumstances. Is it actually practical for a daily driver to be on E30? Thank you for the help.
