I never suffered from throttle closures like you did, but these latest 6 maps are very smooth.

Dude, I am not being a troll. If anything I am posting this GIAC log so that we can compare apples to apples. Obviously Cobb is making more power and more torque than GIAC with meth. How is this a trolling post?

That's very encouraging! 6 maps? Wow! That's even more interesting...

thanks for sharing clap

Im not sure what I am allowed to say, but all the map names are changing. You are going to have 3 maps for each stage based on mods and driving style.

Sounds very intriguing!

So theoretically speaking... since you are already running 18 pounds on pump gas; will running meth make that much more power? I imagine a dyno tune with ATR will add 20 or so WHP but that's about it... unless I am completely wrong?

Keeping boost constant, spraying meth will allow more much more aggressive timing. I can see another 20-30 gain.

So it looks like it will output similar numbers to piggybacks available...what are the upsides? Smoother, more linear power curve?

[vasillalov]

Clap,

Do you know if they put any boost caps? Today I hit 17.6 psi true manifold pressure on Stage 1 and that was at part throttle.

Proper timing control, proper fuel control, proper load targetting, I guess "proper" just sums it up.

this might derail the thread.

are you on the firmware that shows vac and boost?

No. I am on the latest stable firmware and 2.03 maps. However, I watch the actual manifold pressure on my P3 gauge which has an independent pressure sensor and it is hooked up to the DV lines.

EDIT: the p3 gauge also has a recall functionality which records max stored value for last 15 seconds. So I am sure it was not my eyes playing a trick on me...

Sorry, just trying to learn. Not start a debate. That's why I left specifics out hoping not to start a ruccus.

It is interesting you are sustaining close to 350whp on 8 psi boost at redline. I topped out at around 380whp on meth at 18.5 psi peak, tapering to around 16.5.

I want to know if Cobb will release a stage 2 + meth map with an aggressive timing curve and more boost up top.

I suspect the steep boost drop past 5500 RPM is related to the load target limit, which Cobb will have to address with a rewrite Correct me if i'm wrong.

Yea, theres a reason why its still in beta. I wouldn't focus to hard on boost levels 5k and up lol

You saw the vid, you saw the dyno, think logically

Like I said I dont have any throttle closure or boost spikes. So I dunno what to tell you. If I can get my car to do it, I would figure out, but I have nothing to work off.

Maaan, I really really hope this one works well.

No worries. Its just a topic discussed a lot with it generally boiling down to fanboys going at. Both have their str and weaknesses. Just search the n54 section for cobb/procede/jb4/giac and you will find a lot of threads to read various opinions.

[Q4P]

Lol, if I had the knowledge both from a tuning, technical and software engineering standpoint, I would create my own software and tune this mofo to my specs... but given everything available this seems closest to that.

[Brey335i]

Man... 18 psi? That's a lot of boost. And you say that taper is gonna be improved, right?
