I know you can tune with it, I have talked to Jack about doing just that and I am still considering it as an option to pursue. (I currently tune using HP Tuners and Megasquirt Systems using Tuner Studio)
However the Unichip is a little different in the way it accomplishes this from my talks with Jack. I really like what they offer but there are some things I would like to see added to its abilities from my talks with Jack as well.
At this point there are a few reasons E85 could cause an issue (I have done quite a bit of E85 Conversion Tuning myself to pull this from, My Vette runs E85 normally unless making a long cruise) and thats going beyond the ability of the Factory ECU to handle say fueling demand or signal level, or that the person who attempted to make an E85 tune did not have access to a dyno and realized you can pump up the timing rather far and still not knock yet pass Means Based timing and start loosing power.
This is where one of my concerns with the Unichip comes in, the tuning software it includes does not log Knock, your relying on an OBDII reader to do that so you can't get a map of exactly where it happens in each cell without possibly being on a Dyno holding it in each as it happens which if anyone has tuned is very hard to accomplish. (I can provide pictures for reference if this is confusing, some many not be familiar with this)
Either way while it can be accomplished and it seems those selling kits are not mentioning changing the fuel pump or injectors with N/A applications to meet the extra 30% or so more fuel that E85 requires then the hold up, as Jack has mentioned sounds more like something else.
He said it was a legality issue, so again if we can release them from any responsibility to gain access to such files how many would be interested in doing so and truly know the way E85 works and what can happen? I know I would be willing too.
