i use E50 since 4000mls in my 87SE L4 and in my 84 2m4 and no Problems so far with the injectionsystem
only on cold days it need little time until it accellerate normal.
Found a swedish list that say our Engines L4 and V6 can use up to 90% Ethanol mixes .
To make it run on E85 u will need to raise the Fuel pressure , and change the Ignition timing
Best is u use a Flextec ecm that uses the original ecm values to increase the amount and time of fuel injection .
Some ppl say that u have to change all rubberparts in fuel system , but the swedish ppl i spoke told me that only fuel filter has to be changed often in first month after u start using E85.
