issues with e85 ?

[Hobert]

I have a 2019 suburban 5.3 engine that is E85 capable but they dropped the support and left off the e85 measuring system in productions. Others have added the capability back in. I looked at adding it back to mine, the link below will provide a full education.

Just ordered e85 sensor and DSX tuning fuel line coupler lol then run atleast 3 tanks worth of e85 and off to the dyno

Unless I'm mistaken you'll need injectors that can deliver more fuel for the e85 volume. I don't know what injectors you have.

@swathdiver can provide some perspectives on running e85.

The LT engine injectors have that reserve capacity to handle E85 in the L83 engine.

Dummy plug and extra fuel line extension removed from vehicle
E85 sensor and DSX tuning QC coupler installed
Easy peasy, had BBP send over a new tune with enabled e85 . Very simple
