VVEL control unlocked

Well the debate has always been, the system is smart and very efficient for the OEM engine/exhaust setup but does it adapt when upgrades are added (NA or FI). I think between O&G (FI) and now Jordo! (NA setup) we can see there is room for improvement via software tuning when you start to modify the car greatly, potentially not when you just add exhaust or intake but maxing out NA upgrades.

Jordo!

Yep, I don't know about just an intake and cat back, but if you start to get into different intake manifold or headers, there are definitely additional gains to be made over simply adjusting fueling and spark.

That said, it remains an empirical question -- I should think it's certainly worth exploring with intake, exhaust and anything other than the OEM CAT (i.e., HFC's or TP's).

Is this tuning capability generally available in UpRev or is it still beta? Reason I ask is my car will be getting tuned for FI in the near future.

Ill see if I can dig up a NA with full bolt ons dyno graph and show how much low end wtq can be added with VVEL tuning later. JTran did one 2 weeks ago, we were all very impressed.

Subscribed. Very interesting full mod NA results.

Thanks, Jordo! All my tuning experience comes from the "old school" days of claying motors for piston/valve clearance and manually adjusting cam gears to get the correct amount of overlap. Things are much easier now and I'm glad to hear there are some built-in safety parameters within the limit tables.

Double post.

O&G

Here is a dyno graph on an AWD mustang dyno (lowest reading in the land). Car has full bolt ons including long tubes. Car came in with a basic tune non VVEL adjustments. You can see the additional gains after a new tune with VVEL adjustments. JTran has been tuning VVEL for sometime now and has learned a lot.

Yes we actually remote tuned a few VQ's in Toronto and recently shipped a built block up there. We log into your computer and adjust the tunes via your computer, we can even do a live chat during the process. It's very kool!

Can you provide a better picture? Id like to actually see the numbers

O&G

Bigger pic as requested....add about 13% for a dynojet equivalent number.

Nice gain with the VVEL... with some basic bolton.

Ive seen some vvel head assembly that arent to expensive in a few scrap yard . I might end up trying getting the left head with another engine wiring harness to replace the one I modified for the HR heads.
That would only be a temporary untill FI this comming winter hehe....
