not in Beta anymore and any Pro Tuner cable has access to it , I cant say for the Tuner version.

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.

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).

There are max limit tables that prevent taking things too far, so no worries of damage so long as you leave that alone.

Based on evidence from other folks with the PPE headers that suggested adding a mechanical restriction to the PPE headers (e.g., a cat) minimized the small dip in torque down low (around 3.8-4.5K), we decreased cam overlap in that region, and made nice gains, with the exception of a very narrow band (about 4 - 4.2K -- seemingly a resonance issue) where it just didn't budge.

Experimenting with increasing overlap there reduced power, and confirmed that we were making changes in the right direction. I suppose we might play with it all more another time -- I'll keep everyone posted.

Anyway, in the mid range to up top, we increased overlap and made nice gains from about 5K to redline. A small touch up of fueling to help maintain target AFR's and we were done.

Generally speaking, the goal is to set cam overlap, duration, and lift to optimize cylinder filling and exhaust pulses at a given RPM so you achieve an optimal mixture for making peak torque -- it can take some trial and error, although we had a few clear ideas of what to change and where.

However, this is a protuner feature only -- email Martin at rsenthalpy@gmail.com for more specific details on the tune or to arrange for a tune yourself.

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.

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.

So Enthalpy tunes vvel? That's a nice graph

Does JTran do etunes?

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!

and yes, he can also do etunes, but you will have to supply certain data, he will adjust and send back. Just let me know when your interested or contact the shop directly!

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

I can 2marrow when im at the shop. Kinda hard to fit it all in. Screens a 48 inch flat panel. Once agn remember this is an AWD mustang dyno. Pure tuning tool!

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....

Yep. Shoot him an email at rsenthalpy@gmail.com for more info :tup:

A good friend of mine uses him for tuning sr20det's and ka24de turbo applications

wow really? I used to run an enthalpy tune on my sr20 back in 2003 lol

lol me too. but his customer service was horrible back then so i went with the hks fcon vpro instead because I knew a local tuner. I hear nothing but good things about enthalpy now =)

yeah i actually destroyed my first SR running one of his off the shelf tunes lol. my fault for not knowing what the hell i was doing at that age and not checking the AFR, for some reason his tunes never worked well for my car and then I switched to nistune. oh how I wish we could run nistune on the Z

I recognize your sn from zilvia I'm usdm180sx on there lol

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

No chiiiiit, he's tuning ben afflecks car? I expected craaaaazy numbers!

Lol we nick name all our customers

And yes, ben affleck lives in Houston and owns a Z. :p

wow this looks really great, i wonder which parameters reflect to what change in the vvel timing :O

any update on VVEL tuning, and how the car is running...
