Yeah, after reading up a bit more, I'm going to order the hotwire kit to be on the safe side. It's worth the $80 to me not to have to worry about it.

 

I just made a simple hotwire kit on my setup. Ran fused wire from the alternator to the pump, and used a relay off of the factory wiring to kick it on. Worked without a hitch for probably the last 1000 miles.

 

nice! I'll have to look into that or the Hotwire kit,

filled up with 15 gallons of e85 today and drove until it was showing 15.5 on the wideband. stopped and changed stoich to 12.0 and drove until that was showing 14.7 by then my laptop needed charging. I'll do some more driving tonight and tomorrow to get the 93 out of the tank.

 

i plan on ordering an e85 tester just to see where it's at. I will probably play conservative on the tune and keep the stoich at 9.75 and let it go a little rich when it's not true e85. who knows I may make a winter and summer tune

 

nothing real important to update. i have stoich AFR set to 11.0 and the wideband is reading 13.5 its hard to use a lot of fuel when you live 1 mile from work. This weekend i'll take the truck on a nice long cruise. im guessing the mixture to be 60/40 right now. it might even take a few fill ups to rid all the 93 out.

 

everything seems to be settling in,

Stoich is set to 11.3 in the tune VE is + - 2% in the out of boost cells

once i hit boost its rich, wideband showing 10 AFR

hit 165 kpa and injector duty cycle was 103% i should be able to get more out of them by leaning it back out to .77 lambda

i tried make a second WOT pull in 2nd gear converter locked and i could only build 1 psi of boost. i blew one of my charge pipe boots off. drove it home and got it fixed

 

I was going to run twin 450's with an 80lb injectors, but Im wondering if I can get away with a single 450? Do you happen to know the boost potential of the single pump? I know there are a few variables, but a ballpark might get me to sell the other 450

 

A single 450 is good for around 600 rwhp on true E85.

 

So any updates on this? How are you liking it? Got a boat load of timing in it yet?

 

this is def the fuel pump I'll be going with
