My E85 Results

[MSP6]

E85 seems to be working well for me. Not going to post anything in the timing database as this is all VD tuning but I'm pretty happy with it. I'm sure there's room for some improvement but I'm content with the values for a street tuned map. Going to leave things the way they are for awhile.

*Some Notes*

Stock tune map was in January-February (i.e 20ish degrees) sometime so that number is inflated a bit. Mods were intake, TP, TIP and BPV.

"Best 93 octane map" was just that, the best I saw on that tune. Was typically around 280-285whp.

Both "Best 93" and "E85" map are with intake, TIP, BPV, catless ebay DP, EBCS and internals.


Timing as follows, from 2500rpm -1.55 3.00 5.00 8.50 10.50 13.00 16.00 18.00 18.55 18.50

I know E85 is temp resistant but I wonder if an intercooler upgrade can give you a few horses.

[Enki]

It won't. The limiting factor is turbo airflow.

Actually picking up a used TMIC today. Not expecting gains just want to reduce the stress on the turbo a little bit. Map has had about 60-70 miles to settle though and temps are down from the 80's yesterday so I'm expecting some better results from pulls today (still with stock tmic though)

[MSP6]

So like I said above, about 70 miles into the map and here two more logs. Temps were about 10 degrees cooler than yesterday right about 70. Still dynojet correction factor as thats what I started with months ago so I want comparable numbers. But still pretty good. TMIC will go on today and probably some more logs to make sure my WGDC values are still good then sitting back and enjoying the ride for awhile.

That's a nice increase for just a retune with a 50/50 mix.

[MSP6]

I know, it's a little funny and also a little depressing. You spend months dialing in and tweaking a 93oct map to perfection and think its great....Than your first tune on 50/50 puts it to shame lol.

Edit* That makes it sound like this was my first tune iteration which it wasn't. This is 10 or 12 tweaks down te line. But still, first map with same boost and wgdc levels with bumped timing, big difference.

Others may disagree, but back in July when it was like 100 degrees around here I did a run and it showed about 300 at the wheels according to VD. About a week later it dropped to the 70's and VD showed 325 at the wheels. Same road, same gear, so I think temperature still has a little to do with it.

That's a very true point, it's just that an upgraded top mount isn't going to give you any appreciable difference in BAT's. So while a 30-40 degree drop in ambients will definitely allow for a power increase, it just won't happen with an upgraded top mount in similar conditions. I do feel that there's an additional few hp to be had if I were to go fmic, though its not worth the time/expense for gains that wont even be noticeable.

I saw absolutely 0 performance gain by switching out the stock TMIC with an ETS TMIC.

E85 is a honey badger.

It don't give a fuck???

[dead-zone]

When I installed FMIC on my genwon I did not see gain at all too. Bats are just a little better but nothing special. I want to try e85 cause I tweaked 93 as much as I can, make 305whp. I really want to try e85 but kind of scared of getting black death. I might try 25% mix.

@MSP6, let us know how your pump is on the 50/50 mix.

Hope you don't have to deal with all that black death.

Clean your pump every x about of miles. Death avoided.

the general consensus is that you're aight on 50/50 and less mixes of e85. no signs of problems here, and I've been running e29 (9 to 3) for a couple months. one you start though, youre gonna wanna keep upping the mix lulz. wait til you see how your car runs in the heat of summer, you will be very impressed.

[dead-zone]

I am totally for upping timing I was thinking to try what you said 9 to 3 mix. I wonder if it is worth it cause winter is on the way.

[MSP6]

Yep general results so far are 50/50 is fine. I've been on it for maybe 2-3k miles so far, about 2 months. However, I have run a couple of tanks of 93 through as well so my results aren't definitive.
