Thanks for the heads up on the e85 stuff. I learned some stuff there. As for waiving the rights. I have no issue with that as well. I've been dying to run e85 for a while now, and I have a station literally around the corner from me.
As for the abilities that are to be added. It always seemed that Jack has stated anything COULD be added to the system. Question is if the unichips we have are capable of doing what it needs to do.
Cross is there a way you could come up with a unichip tune for e85? I have access to a dyno at my school (Im a physics teacher), but I have no idea how to tune. I'd be willing to help any way you want.

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 seem 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.
