Hi again

Nissan anounces VVEL range is up to 288 Deg 12mm lift.

But from our inspection, VVEL cannot reach 288 Deg.
Less than 450 Rear Wheel HP, 288 Deg is enough.

Around 400 RWHP, VVEL mapping was not effective.

Ignition timing map modification is much more effective.

We make the remapping devices and software from scratch.

From our experience, even 500 RWHP doesn't require any other additional piggy bags.
I will post the idling movie soon.

Almost the same as the stock one.

Any question appreciated.

Regards

modifiying VVEL camshaft is not easy.
As far as I know, none of the EMS have the ability to map VVEL, we can log it however but no mapping.

So in order to get less than 450 WHP, you can do that using Nissan ECU VVEL mappings? would you mind elaborating what Engine management system you use for that?

All my exhaust components are non-stock, so I am assuming that going with Exhaust camshaft should get me more HP.

Is the IDLE rpm affected with exhaust camshaft?
