OK - did some searching for alternative systems to ProEFI, but not gettign anything solid on the ability of the systems to adjust maps/timing based on Ethanol content using flex fuel sensors. SO what other systems are there that I can use for E85 AND 93pump? The ProEFI is very nice, but also $2G

 

MS3 can do this:

lol - I kinda jumped over MS's capabilites. This is good to know, glad I didn't buy into the ProEFI thing last spring, some are catching up.

 

So can the latest MSPNP Gen 2 models.

 

The new Adaptronic 440 can do flex fuels. Just curious though why not just run tune for E85? Any standalone should be able to run E85. You can even run it with the normal gasoline wideband sensor.

 

Problem in the South is the availability of it - either I have to haul 50+ gallons to the track, or take what I can - when I run out use 93. I currently have 2 6gal fuel jugs, will proably get 4 in the future - no one likes buying fuel at the track, even for 93.

Thanks for the input guys - I'll discuss these other options with my tuner.

 

Well the other option is keeping your laptop in the car and switching as you fill up but thats a bit nasty for the first 10 miles until your fuel system gets cleared out.

 

Barber's price for 93 isn't much more than outside the track.. I was surprised.

 

Should not have read this. Off goes another e-mail to Dimitris

 

One of Sixshooter's associated friends melted his pistons in his GTR because he forgot to do this... went from E85 to 93 and destroyed the motor


I fill up at the pumps there, but the closest E85 station is 30 min away, sadly.

I'm starting to wonder if it's even worth it - really?

 

Afrs would be in the low 9ns at that point... An AFR gauge will tell you that.

 

well, my tuner wants to got AEM - any reason not too?
