Is there any handheld device on the market that I can load my tunes onto so that I dont always have to carry my laptop?
I just started running pump E85 and would like to easily be able to switch tunes at the pump if it tests higher or lower than before.

Thanks!
Not that I know of.
Besides it really doesn't make much difference if it's E60 or E75 at the pump. I've seen it and watched others report the same thing, that over 50-55% it's going to work the same way.

If you don't post your tune and logs when you have questions you aren't helping yourself.
It absolutely makes a difference.
The stoich point of E60 11.28
the stoich of E75 is 10.45
Theres a pump here that pumps 83~86% every now and again.
If your tuned for 75% and pump 55% the car will be crazy rich and you will have too much timing in it.
Your car uses closed loop power enrichment, it will target correct lambda pretty consistantly with that small of a variation in fueling
also timing will really not be that different from 50-70%, i highly doubt there is more than 1* difference.
Leave that 1 degree out and ship it

I was assuming this was running a alcohol sensor. I use one on my truck so I don't have to do anything special because the computer does it for me.
My point I guess was that the timing and commanded fueling for wide open throttle doesn't really change at all between that 50-70%+ alcohol content.
