Stalling on e85

[Cruzin50]

So I've been running 100% e85 for about two months. Everytime I've tested it the fuel came back around 75-80% e85. I'm also tuned with lund and actually already emailed them but still waiting on a response I'm sure they're going to want logs.

But I've noticed at low rams, especially when cold starting the car stalls out very easily when trying to go into first gear. The idle is fine. But when I try going into first or reverse the rpms start to bounce pretty bad. So I usually have to throw it back into neutral to steady the rpms again, then go back to first. It doesn't really happen much when the car is warned up. But if I'm feathering the clutch and trying to roll forward slowly the rpms start to bounce again.

This is my first time with 100% e85 so I'm not sure if it's just a normal occurrence or could this be a tuning issue?

Thanks in advance.

Are you manual or A10? When I ran e85 I noticed if you feather the clutch on e85 when rolling slow, fords anti stall crap tried to adjust for you and revs the engine. I almost never had it completely stall but it would come close. If your manual that might have something to do with it.

Yes I am manual. Thats exactly what happens. Before E85 I would usually get into first with barely any gas. Now if I try that, my rpms start going crazy.

Yup. Mine never went away but I noticed if my E content was low and there was more pump gas in the tank it was better. The higher my E content went the worse it was and with just 91 it disappeared. I've always pulled out slow or backed up with very little gas, feathering the clutch but I had to switch it up on E. Little more gas and more clutch and those situations go away. I always worried I'd burn my clutch up prematurely but I'm at 56k miles and boosted now and it's still holding strong.
