A quick and easy way to street tune your CSL conversion for drivability.

[Bry5on]

Ran through the karter16 updated VE tuning method on my car today. Car is running Bry5on's latest mullet (v28) and I disabled MAP and adaptations during the data logging sessions.

Here's the final change compared to the baseline after three iterations:



There was a little bit of weirdness left down low (<1500 rpm and <~1.5 relative opening) before the tuning. It was mostly noticeable when pulling away from a stop and when feathering the throttle right before fully disengaging the clutch on upshifts. Was extra noticeable with the stock comfort throttle mapping.

But all that is practically undetectable post-tuning! I'm super happy with the results. Drivability is very, very, very close to stock now.

Super wild how different the results are between the two cars after running the same optimization! I wonder if you have a looser ICV than I do? That’s the only thing I can think of that would need that much extra fuel down low.

Yeah I don't get it either. Injectors are the only other thing I can think of. Although our cars are dead on in the upper RPM/load ranges, not sure what to make of it.

I have a set of TT injectors in the garage, but haven't swapped them cause I haven't been ready to go down that rabbit hole.
