I am running a roots blown E85 set up (injection above the blower only, no port). Originally, Peter Florence (very talented tuner) set up my system using the standard AFR for gasoline and just tuned accordingly. My engine seemed to be happy around 11-12 AFR. Anyway Im thinking of switching my Innovate ...

Im new to tuning so spoon feed me. I have a roots-blown, e85, MS-II application currently has a basic tune for 6 PSI at WOT that was done on a chassis dyno by a professional tuner. The MS-II is being used for fuel only! I want to change the pulley and start getting the boost up for the track. The ...

logical pv=nRT....

So now I am suffering from cold sink! Due to adiabatic cooling above the blower (especially with the E85), the IAT is seeing colder temperatures that what would be representative of the charge going into the cylinders. So, should I reduce the IAT correction? Will it accept a ...

Matt,

reviving this thread. I am running a blown application, e85, injecting above the blower only. I was running the IAT below the blower but getting terrible heatsoak so I moved it above the blower. Under normal conditions, does the IAT signal with increasing temp adjust the fuel curve rich or lean ...

Yea, something like that.. Just expect to have to re-tune fuel to start up. I think I did it with req_fuel in general... That was enough for me to put-put away from the pump.
It took a surprising amount of fuel.

Turbos love E85 though..

my shop sells e85 and I still haven't tried it because I want to run a flex sensor to tune in correction i.e. ill know whats in my tank while i tune so i can compensate for future mixtures

if i was gonna just dump e85 into my empty tank, i'd probaly add at least 20% to req fuel and maybe an ...

I haven't tried going leaner. Just be aware that AFR targets are not going to allow you to start up.. You're going to be 20-30% lean across your fuel map and depending on AFR targets, even with high EGO correction probably won't work very well - might limp you home, but probably not. It'll be dying ...

... more fuel, maybe I didn't take req fuel into consideration...

with that said does anyone know what an ideal table would look like for example 12.5:1 for gasoline and I've heard you can go several points leaner on e85 without issue, does anybody agree? keeping a close eye on knock and egt that is :)

... Practically speaking from someone who has made this change at the pump.. The first time I tried it, I nearly pooped myself. I added a tank of E85, increased my req_fuel value about 25% and restarted.. It immediately died.... And I thought I was stuck.

I found that I had to do two things:
1 ...

to avoid starting another thread I'm replying to this one.

I have been thinking about switching to e85 for a while since i sell it at my station :)

I was told I could switch fuels without making any setting changes (using gas values) and all i need to do is re-tune VE to get back to target AFR table ...

... first denatured with approximately 41/2 percent gasoline, before being mixed with anything else. When an ethanol gasoline mixture is advertised as E85, the 85 percent ethanol was denatured before being blended with gasoline, meaning an advertised E85 fuel contains only about 81 percent ethanol. The ...

Matt,

No worries. After talking with Peter, we felt it would be easier to just use the standard gasoline calibration numbers in the LM programmer and the LC1 defaults in the MS. O2 readings are currently showing about 10.0-10.3.

OK.........such as? A tad more detail would be appreciated Matt.

For E85, use a custom calibration.

1. I know I go to the calibrate ...

Right now my Jeep uses a distributor to manage the timing and ignition and I have read that switching it over to a distributorless ignition will ...

Why do you have AFR set to 9.8 (normally set to 14.7 for gasoline) in your ReqFuel calculation? That will cause a profound difference in the pw calculation!
Just to clarify my question..... 9.8 would probably be close enough for E85..... your earlier post didn't specify which you are using....

They also demand a TUV test if there is no data from the manufacturer on the emission data for a engine that is converted to flexifuel/E85.
