2017 ZL1 E85
What's the secret recipe to run E85 in the 2017 ZL1? We installed the flex fuel sensor from DSX Tuning, tuned the car on 93, switched it over, and ran into some problems with the fuel pump. Is this common, I was under the impression it was pretty straight forward, install the sensor, add E85, tune.

Bump. What did you end up doing?

It's not straightforward. I know some of the best late model GM tuners in the country and they won't switch the LT4s to e85.

We do them but you have to do an upgraded cam.

We ended up being able to get it to run on E50 with only Flex Fuel sensor. We can get it to full E85 by adding a low side pump.
