Hello, I can post the tune when I get home from work. Thank you
Here is my numbers for stoich, do I need to change them to 9.85? my numbers across the board are 14.10840 under alcohol composition? I cant find a way to post the entire tune on website. Thank you for any help I can get. also spark smoothing says disabled is this correct?
A stoich table that is using E85 will be sloped. It's going to start at 14.68 at 0% and go down to 8.9 at 100%.
So find a stock flex fuel stoich table and paste that in there.
Copy the stoich table from my trucks tune and it will work.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
I have a 2017 SS and all the e85 tables are populated. I turned everything on just waiting for my sensor kit. Are the prefilled tables close or way off? Would i just adjust the afr table to make it linear or is there more that needs adjusting? Stock car but want to run e85
