Re: 880s, maft translator, and e85 = workable
I got you covered.
Of course you can run it on e85. Back in the day I ran 950s with just a translator, datalogger, scm61, 272s, pump gas. The problem is not the maft. It is timing maps you get when with taking out airflow to compensate for bigger injectors. With the way the system works you will fall under a more aggressive timing curve since the ecu is seeing less airflow. The only counter you have to this (without dsmlink, or a chip burner) is to lower the base timing (1g). There will be a side effect to this, but it is minimal. The car will be a bit sluggish until boost hits, but you will however have the high wot timing advance under control. At around 17+psi with the 950s (I ran 25+psi) I was hitting 25-29 degree of timing advance at wot (as seen with my datalogger). I wanted to peak around 17-19 degrees so I set my base timing to 5 after tdc. The factory spec is of course 5 degrees before tdc. With 10 degrees of base retard, I was able to hit 15-19 degrees during wot instead of the 25-29 degrees the ecu was giving me (the datalogger will still show 25-29 degree of advance, but you will be at 15-19 degrees and all your knock problems will most likely dissapear.
My car at the time went 12.0 @ 120mph with no knock probs. Drove it for the entire summer until I got dsmlink. You probably will not have to retard base timing that much since your injector size won't be as high as what mine were (ecu will see more airflow, closer to stock, giving you a less agressive timing curve). I'd start at 0-2 degrees base and go from there.
