He pretty much ran a low boost map, plus 1 psi from the jb4 due to shitty meth flow. JB4 won't add timing, meth wont do shit.

The way I see it, he ran 119-120 on pump gas and low boost.

THANK YOU THANK YOU THANK YOU!




THANK YOU lol

Dzenno, I don't have much to say about this thread other then congrats and keep it up... but a bit off topic... I want to thank you for making this thread because after seeing all the posts by people who are truly clueless as to what these results represent it makes me feel like a tunning mastermind I actually feel pretty damn smart right now LOL

You are explaining things in technical terms and it's going right over peoples heads so let me try and explain this in a Dumbed down version.

Basically everyone has been running 11's on Jb3 map "X" lets say, which is the race map... dzenno basically went to the track on Jb3 map "y" which is the low boost daily driving map meant for the longevity of your turbo's... but still hit 11.9. Now sit back close your eyes.... and picture dzenno putting his car onto map "X" at the track and think about what will happen??

With more boost up top (where the majority of a drag race takes place) and even a slight improvement in 60 foot times I don't see why you won't be breaking into the 10's. Keep it up man, bring the 10's home to Canada


OH and also, for those who think my dumbed down explanation was too dumb, just think about it this way to keep things simple... although it seems like he was running 17-18 psi boost for this run which would have resulted in better times if he had a flatter curve, you have to consider the boost dropoff in the higher rpm range... and if you've ever gone WOT you can see what RPM range your car mainly stays in. If the meth was flowing and the jb4 integration/safety mechanisms were working as planned... this would have been fun to watch.

pretty good working on it man, always working on it

did you run the wot box?

no left it at home...but i used my AR line lock every single run and man does that thing just make the burnouts piece of fucking cake seriously...go through the water box slow, stop, hit the switch, burn out get a cloud going, turn it off, line up, 4k rpm and GO

thing about wotbox and NLS specifically that I noticed during some testing is that after the shift it'll make both banks run leaner than target for some reason...so instead of holding 11.5 it'll hold like 12.5-13 AFR for some reason, flat, and then pick up again...some say the DME, due to the ignition cut, will run open loop for a bit right after and then pick up closed loop again, not sure what to think there exactly just yet...I'm not running NLS until I can dial it in properly and as far as 2-step, I probably won't even need it as much given almost consistent 1.8 60' I can pull of on melting DRs and a 4k launch

AR line lock was a total win though!

Your using MT's so your answer probably won't apply to me, but did you notice your car dead hooking with the AR line lock kit? Were you not dead hooking prior to the kit?

Not on my personal car, but on the "drag monster" a buddy and I are working on, we're having trouble dead hooking launches on NT555R's sometimes (6at 135i FBO+meth+n20), if a line lock kit can improve launches significantly it would be the next mod.

[Alpina_B3_Lux]

It's quite amusing (for a while) to see how many people posting here have absolutely no idea whatsoever about how the N54 engine works and, as a consequence, a good tune should be set up. It probably also has to do with this slightly anal fixation on 1/4 mile times, if you allow me to say that from a European perspective.

The only thing that surprises me even more is how so few engines have gone bust so far, with people like that putting user-configurable tunes in their cars about which they don't know anything at all.

Anyway, BTT: Quite interesting what you're doing here, Dzenno. I'm reading this with interest as I'd also be potentially interested in a good flash tune for upgraded turbos. Good to see that such results are possible without even beginning to exploit the RB's potential. But then again, I know that a friend of mine with the TD stage 2 on 16 psi (without meth, race gas or nitrous) is crazy fast as well.

BTW, the tedious process of programming the load tables is also what took GIAC so much time with their stage 2 tune. Good to see that COBB is going through with this.

Great info dzenno and thanks for sharing. A few bastards shows their origin and current status and are not capable to receive the info you provided in OP.

[Overboost]

I understand how the JB doesn't affect timing due to lack of CPS offset, but how does it not affect the preset COBB AFRs?

OMG what happened to this thread in the last few hours..

Just an attempt to clarify your statement. Good run Dzenno

Missed this one somehow in all this nonsense thanks man and yes the misfire diagnostic had to be turned off until there's more time to spend on things that don't matter as much as hitting 10s lol

I've set map6 fuel settings to zero meaning that it won't offset DME's fuel control..

totally expected man, took me a long time before I finally pulled the trigger to post it...

[Alan l.]

Congrats man.

Some of you guys make it out like every piggy car here is running 11's lol I thought the same too when i first joined with a few individuals posting unbelievable times but if you dig further...not many others are doing the same.

LOL @ folks that only look at the time slip as the whole picture. Was expected though considering most on here pick up the cheapest tune possible without factoring in anything else.

Great thread Dzenno, keep it up and dont mind the haters. Its people like you that take the N54 to the next level.

[themyst]

Don't feel bad dzenno, lostmarine did the exact same time last year on a jb4 auto plus meth and upgraded turbos at atco in near freezing temperatures.

At least you're trying something different!

On a brighter note, I ran a 12.8@114 misfiring into 4th that same day

Yeah, with all the potential for more power laying on the table for him I'm pretty sure he's not feeling too bad rather yet he's probably pretty excited haha... car's running good, all his technicals look good... it's just a matter of time now.

I will try to show up to the track the next time you head out Dzenno, would like to see everything go down in person.

[Irishace]

Nice work bro, I know its been a long haul. Cobb has a ways to go but I like your innovation. It really is pretty damn impressive that you ran 120mph on basically a pump gas map.

[Clap135]

LostMarine ran 117ish at atco on pump and meth on full weight. He then put race gas in it and hit 122. Like I said before, race gas and meth wont do you any good when your timing/boost curve is set up for pump gas. If anything it will slow you down.

When I tried spraying at the track on stage 1, I lost 1mph, turn it off, gained 1mph, I did this for 4 passes and got the same exact results trap speed wise.

[GeorgiaTech335coupe]

I don't think you can say the meth did nothing. It allowed the map to run its best possible timing the map allows on all runs and provided colder intake temps that he would've seen w/o the meth.

It's not your typical meth bump in power, but almost the same as racing in extremely great weather conditions.

[Joshboody]

GOOD RUN Dz!!! Looks like most aren't getting it, but any flash won't reach meth, race gas potential unless it's a custom/race map (like Mr. 5) or some outside the box thinking... which you had, but unfortunately meth flow wasn't there. You do really need the timing advance to take full advantage of race gas and/or meth. I'm sure it will be awhile for Cobb, or they'll just let ATR peeps mess with it.

EDIT: actually just noticed that Cobb is working on race/meth maps.

I just ordered prodeede and devils own meth kit for my car from a great vendor on this forum that's why i joined.

i was thinking of getting a cobb

but after reading this i think im better off with the proceede , i dont want to buy a tune then buy another one to go with it to control my meth and raise my boost . seems like more work for the same results.

and enrita aren't you the same person who i was just told blew your motor with the jb3 ??

what do you think about him using jb4 to control his meth???

thanks for this thread and info guys... just saved me some money and time!!!!

Problem is that the procede wont control your meth kit....You need the vishnu kit or you can piece it together yourself and then break the failsafes every couple of weeks. good luck with that.
