Anyone running two fuels/tunes?
nodrok, thank you for your input, it really does help.
aside from the injector tables in the tune, what would be the proper way for changing fuel? I plan on keeping the stock tank (plastic), and I'd imagine I can't just pour in x gas and switch go x tune while y fuel is present, correct?

You would want the tank to be as empty as possible. A little E-85 in your gas will make it run leaner, and gas in your E-85 richer. If it's less than 2 gals and you fill up I wouldn't worry about it. The key would be to make the gas tune extra safe, that way if there is some E-85 left it won't lean you out too much. You'll be running the car on E-85 almost all of the time with the ability to use gas if you can't find E-85 if I'm understanding you right. So the gas tune can be really conservative.

Good luck
This is the simple yet very involved solution. 2 separate fuel systems separate tanks. Run a stock and run a cell. 2 tune ecu 8 injectors for gas 8 for e85 flip the witch for tune/fuel cell run for 5 minutes while switching fuels. This can work, but who wants to put an additional fuel system? No one. Maybe th ID2000's can do it. I dont know. I would consult a credible tuner. They will know for sure. Make sure you get a second opinion because some tuners may not want to open that can of worms. I am interested because I will sell my 96 pounders and buy the ID200'2 get some new pumps fuel lines (teflon instead of rubber) and do what you are doing. I was going to do this originally but was talked out of it. I may see 800-900 AWHP out of my silverado ss after all.
Good luck

ID2000's have been made to idle in a stock DSM I believe. They are the end-all be-all of high impedance injectors right now. They are one of the few high impedance capable of making big power on E-85. Your twin fuel system setup would be more precise when switching fuels and tunes though.

Verdad Gallardo good info folks:
FMX05, other way around; 91 most of the time (very conservative) and E85 race duty (aggressive)
Nodrok, as I stated earlier, very helpful thank you.
So now it looks like it can happen, what would the fuel system be? will twin intake 225s, aftermarket rail and ID2000 suffice ( i know that just scratching the surface, I want to keep it general because it looks like other folks are interested as well)

Well if that is the case just make sure to run it down pretty low before your fuel up with E-85. What is your power goal? Dual Walbro's doesn't go very far on E-85. If Dual Walbro's will get you where you want you might be able to get by with less injector.

What power level? I have dual walbros. If you want big power you need trips. If i do my fuel system over again i may have gone A1000 just to make things easier.
I saw that last night, I'd spend that on AFR heads befors injectors, but the are the injector to end all injectors, but I know there has to be a cheaper solution.
I'd like to trap 150 mph and get kicked off the track (10pt + T Tops = UGLY), I believe Mighty Mouse is running trips..
So you saying test the batch befor using/tuning for it? I understand E85 and Samuel Adams both have seasonal blends lol.
I think I may post this topic in the Tuning and Fuel forums as well

Has anyone tried using dual bosch 044s?
