VVEL control unlocked

I personally would never load a locked tune unless the tuning was being done for free by someone local who doesn't mind being bugged for tweaks.

Remote tuning is based upon the tuner's experience with tuning that particular car or, more specifically, engine and "what makes power".

Data logs can't log power output. Most e-tuning is just to keep AFR in the range that's wanted as well as any other indicators the tuner knows to look for based upon past experiences with that engine.

The only way to effectively tune specifically for power is to do it on a dyno, in real time, so that the tuner can see what does and doesn't work with a particular setup with a particular set of environmental parameters.

I've started arguments on this forum with statements like that, but it's true. You can't do science without proper data and you can't get the relevant data needed to be 100% accurate without collecting that data yourself with proper instrumentation. Everything else is best effort with known parameters.

(Which to be honest, is more than enough for most of us haha)
