Looking to improve our 1/2 speeds this season with the 2016 Hellcat on E85 and 17psi of boost. We're going to eliminate the cats to avoid cat temp fueling and swap to a 3.09 gear.
For the cat delete, I've eliminated COT/EOT Enrichment (0.0), set a minimum FA Limit (FA Max), bumped the Converter Overtemp and Exhaust Overtemps up to 1850F (along with the targets), and gone through the Engine Diagnostics and unchecked everything to do with Sensor 2 errors. Sound right? Do I need to catch anything under the Close Loop Enable Rear?
We're also dropping a 3.09:1 differential in it. There's nowhere that I see to make a gear correction so I'm assuming its buried in the Trans controller somewhere. Anything that can be done to correct the speedo, shift points, etc?
