UpRev full tuning capabitliy??

Jordo!

Yeah, but not optimally, especially with FI...

That's a bummer... I'm surprised no one has at least figured out a piggyback method to spoof signals like the camcon does for VVTi and i-vtec

Can anyone even access the factory maps just for purposes of viewing?

FI and VVEL can play very well together at the current levels, now if you are wanting to jump up to the 700whp range then maybe not.
The thing so far with Uprev, as they have told me, is there are no components that would take full advantage of VVEL and there is a concern that using the stock components would be useless or maybe "dangerous" for the consumer.

It is a bit of a back and forth, but I understand them being cautious with it currently.

No components? You mean like a different set of cams? Stiffer valve springs? You don't necessarily need any of that to take advantage of VVEL tuning -- that's ********.

Valve timing overlap and lift play a huge role in power production and effeciency by affecting the rate and volume of air ingested, the duration of time it stays in the combustion chamber, and the rate that exahust is expelled. Too much overlap, and you'll blow the mixture out too soon, too little, and you'll have too much backpressure.

It may work fine and safely with boost, but I highly doubt it is optimal because once you start changing the intake and exhaust system, the valve timing should be adjusted too.

There's no more danger from a poor VVEL tune than any other improper setting on AFR or ignition timing.

But, whatever, if they can't do it, they can't do it. Obviously it works well enough without VVEL tuning...
