resurrecting this thread. I got a LBO ls1. so far I am collecting parts to be able to run e85. I'm currently running a walbro 255 fuel pump and hptuners software with AFX powerdex wideband. the following parts I have sitting are l67 gtp injectors that flow 42.5#. am I missing anything else to be able to run e85 such as flex fuel components?

I'm currently running open-loop MAF (OLMAF) and a few members on ls1tech said that I wouldn't have to worry about the closed loop stoich or anything related to the closed-loop so whatever the wideband is showing for air/fuel ratio just tune as if I'm already running 93 oct. that correct?

lastly aside from adjusting IFR and cranking fueling at start-up, what else should I adjust/change?

TIA
