God I hate how this VVEL is a black box that we just have to live with

The ECU calculates the target valve lift based on driving conditions, and sends that info to the VVEL control module, which in turn controls the actuator motor. So, theoretically, UpRev should have the capability to precisely control VVEL.

Yeah, but it's probably determined by referencing a load x RPM table, so it would still be ideal to edit the actual values in the table directly.

Although, I suppose they could spoof it by sending altered MAF/load readings, and then just adjust AFR and ignition to compensate, but that might create all sorts of weird driveability quirks.

Calculate? Are you certain it's not just another values in a table like Jordo suggested
