But look! The commanded AF still goes down to 9 wit 100% ethanol
Is that normal?

I believe so. E85 has a different stoichiometric level than gasoline. I don’t understand all the Lambda air/fuel business. It also requires more E85 flow so your injectors should be bigger than most guys who aren’t flex fuel. Maybe 38 pounders, not sure off the top of my head. Your Flex Fuel pump is also a bad ***, I’ve seen it support up to 700rwhp with no voltage booster or in-line pump.

Lol, I understand 100%

So did you get 5.3 FF injectors with the swap?

I'm curious how the truck ran on that tune. Did you load it up yet?

kr1s

Do you know what truck the power pkg came from? If you could get the VIN a dealer might be able to tell you what OS was loaded in it from the factory. I know the electronic traction control or the rear gear being wrong in the tune can throw it into REP and the TB can if the voltage is off.
You are running the PCM from the older model truck? Is it a 0411 PCM?

It was off of a avalanche
Here's the vin
