C63 LTH stock tune
I've been running this setup catless ever since I saw the complications surrounding running a ECV7 map without a mygenius. I bought the car orginally with a v7 and it wouldnt pass inspection and they wanted to charge me some good $$ to tune then retune. So I unlocked the tuning software via HP tuners and as many may know it automatically gives you the oem tune and then i passed obd readiness with some trickery lol ( its always a hit or miss fml with 02 spacers). To my surprise the car was able to hit higher peak timing numbers and the tranny felt way smoother. I also couldnt tell the difference between the v7 and stock but the data can contribute to that feeling. I have been driving it on the factory tune till i get some things sorted but im curious to how my car would perform dyno wise and 1/4 trap speed wise. Im assuming oem is 340-360whp dynojet and 112-114mph stock non p31 car. this car gets driven 1 hour a week if that, strictly a weekend car.

Eurocharged tunes are notorious for being not very good. Rough shifting, and not very consistent. They only modify some of the maps and end up with incompatible data points and the car behaves weird because of this. You are better off having it tuned properly

yeah just wondering what the stock tune LTH numbers were
I didn’t wanna tune the car till it’s 100% ready, don’t want anything to effect the tuning process

yeah it's fine to drive without a tune I've been doing it a couple years kinda like you finalizing a few things. It runs a bit rich but not going to hurt anything, I'm hoping to get mine tuned this year usually do it myself but will probably go with Barry so I don't have to spend as much time learning these ecus ~~ laziness 😂

I really wanna run like e30-40 e85 too bc I saw that was the money spot. Plus I’m assuming since it’s a blend it won’t destroy the fuel lines if it sits
