Problems with dedicated E85 tune

[K44]

What else besides ECM2300 controls AFR?

I flashed with this at 9.8 I have tested good E85 in the lines, flashed after the flex tune matured. The car's dash showed 9.8 before I started the engine. When I started it it obviously was using 14.08 as lambda 1. Ran very rough and when the wide bands came on line the dash went to 20 to 1. It slowly fell to 9.8.

I went for a drive and the LT's locked in around 15%

I was assuming ECM2300 would lock in whatever number I put there as lambda 1

No one has any ideas?

Tune was solid before switching to E85?

Yes, the car is not accepting any changes in the stoich table. ECM2300 or FUEL>GENERAL>STOICH AFR

2300 table is the only one I changed for my e85 tune. Sounds like you got something else going on, air leak, low fuel pressure, something

For some reason once I flip on the flex fuel switch it will not accept a stoich change even with the switch turned off. I created a new tune using my original base tune and it works fine
