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

I am sure that they have either been working on a solution diligently (or just sitting on it). The thing that has me wondering is...........why did Cobb jump ship like they did? Is the solution that difficult? Is it not cost effective?

damn good question. I also heard AP support for the 370z was no longer. I don't understand that, as trey cobb owns and drives a 370z doesn't he? weird..

is it a waste of money to uprev a stock 370z? What would I get about a 5-10hp gain, for how much?

yes, a waste of money.

so this leaves everyone to wonder what type of HP can be made by cracking the vvel safe... lol

Time will tell! :P
