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.
