    There's no need for a lot of things tuning up to an OEM map sensor lol. Different approaches for different folks. I've personally never used cobb for the gauge functionality, I'd just datalog whatever I wanted to see with it and that was fine, so I have little perspective on what it feels like to lose that. Naked is probably right, that's how I felt losing 6cyl timing back in the day, but I knew what my car liked from countless cobb logs so it wasn't much loss. Honestly I could care less if this ends up tracking on the dme only at 30psi as jerry rigged as the WGDC tables would have to be, I'm just interested in the performance as this is the first kit I've been enticed by (I also like the stage 3) that happens to be priced closer to obtainable. I think Terry's comment about the 30psi thing was just to emphasize that the way you have to tune for 30psi flash only, you could accidentally hit 50psi by some fluke (unlikely for you, but likely for the customer in Austria that runs the same flash) and the computer would do nothing to correct the boost situation, and if it spiked lean durring that time would just chive on pulling timing as it starts to knock to try and save the motor, maybe limp mode if you're lucky enough to get a few misfires. Would it blow? Psh this is a N54! Probably not. But it's rude to do that to the poor car when the tools to combat it are available. Just be patient. And it's ok Dz you don't gotta lie to kick it. Everyone's got opinions some just take them more seriously than others, you're at least willing to compromise at some point, that point being tmap limits. Beats many rolling around here and makes you a better tuner in my mind by keeping your options open. Added complexity to a system is acceptable when redundancy, safety and control are increased. That's my view on most things cars or otherwise. I'm sure this thing is going to impress however you knock it out and give rob a nice lofty target to try and aim at.

    Wayne and Harrison are gr8 receivers but not on the same lvl as Rice. Harrison isn't a first ballot HOFer. My point about the backups was more about the team around the QBs. I think Peyton and Montana had better supporting casts. I do see your point about choking cause if you look at Peyton's stats he has thrown INTs in all 3 Super Bowls he's been in (including 2 pick-6s) but his teams have all been inferior to Brady's IMHO

    Hmm, I've gotta agree with Sticky on this one. If you look at my pick for greatest QB, (Montana) he had a HOF receiver for 1/2 his career and one or two HOF defenders on those 4 SB teams. He was the best player after Jerry Rice (arguably) on the team. Peyton is by far the best player on all of his teams except maybe his first year when he had Marshall Faulk as his RB. Peyton carried his team to the playoffs and then they come up short because the rest of the squad isn't that good. My example is when Peyton missed the entire yr and the team tanked. Worst team in the league. When Brady was lost for the yr the patriots still went 11-5. I say this as someone who doesn't like Peyton, Brady or Montana. I think the choking label is a little unfair but as Parcell says' "you are what your record says you are"

    Believe me I feel you. In the end though it's just work. I want the functionality included for our JB4 customers and working with Tony is the best way to get it for his turbos. It's amazing how much easier it is (for me) to work with RB though. I just show him the data, he provides feedback, I provide feedback, and we figure out what needs to be done. With Tony it's always so dramatic for some reason. Just like with the N55 turbo we tuned. In the end we got the result we wanted with it and hopefully we can get the result we want with these too.

    There are a few things I like in your flash compared to the free stuff. One is that DME boost set point is set to 20psi across the board. I presume 30FF has also been disabled? With the free software we can only go up around 12psi at redline which means less overall resolution in the high boost range. It's a bit annoying. The only issues I see with the 20psi set point is there isn't much room to go over that to control throttle. The JB4 monitors boost vs. target and as boost passes target the JB4 raises ECU PSI over DME PSI to start to close the throttle. The mapping of that is user adjustable in terms of aggression. It's also important for DTC so we can quickly knock down torque when DTC kicks in. But with the set point at 20psi going to say 21psi will trigger a map sensor over limit code. Also the throttle stuff has been effectively disabled. I think a good solution would be to lower DME PSI to say 18psi and restore the OEM throttle behavior. We'd still have plenty of resolution for higher RPM tuning but retain that critical throttle safety. Another interesting thing that I also mentioned to Tony via email was the JB4's on the fly PWM trace as compared to the duty cycle mapping you came up with. The JB4 logs the DME duty cycle even though its not used as part of the tuning just so we know when the DME is trying to go limp. What was interesting is they are almost identical. So the duty cycle mapping you came up with looks pretty close for single gear pulls. The issue is of course you need to run it through a PID with boost as the set point so it can react to dynamic changes as you row through gears, EGT builds up, weather changes, etc. I noticed the DME is going 80% duty cycle for spool mode instead of 100% on the JB4. Not sure if it makes a performance difference. We'll have to put a vacuum gauge on the gate to compare them some day to see if it matters. If the 100% is giving more vacuum it may help spool up a bit. It looks to me like the JB4 PWM is holding a higher value longer in to the spool than the flash only duty cycle you programmed. Yet Tony swears it was spooling faster flash only. So that is something that still needs to be looked at. I think we can hold PWM a little deeper still in to the spool but I really need to see longer runs with various boost curves to map the turbo performance out first. The last firmware I sent him I actually increased D to drop PWM more aggressively during late spool as he noticed over boosting on the physical gauge when he wasn't logging. Yet another mystery to sort out.

    I think the JB mobile will be perfect for you. There is no setup or anything. You just plug it in like the AP and start logging, stop logging, and email the log. You can also view the gauges, etc, on the fly in there. With your setup what you should be looking at since you have a mechanical boost gauge is ignition advance on say fuel and air/fuel ratio on oil temp, with stealth mode set so they only come up at full throttle. The timing gauge shows the lowest advance of 1-6 and AFR shows the leanest reading of either bank. Very useful stuff on the fly. On the flash only stuff, one big problem from my perspective is the logging. There is no single simple log showing all the critical factors in one spot. Boost comes from one system, DME from another, and they are not connected. I presume it's a big production to get everything logging simultaneously. But among the issues with duty cycle tuning without a PID is boost creep as EGT goes up. Once you can get some longer logs we need to evaluate that and then if necessary adjust the EGT factors in the JB4 specifically for these turbos.

    Im sure it could be detuned at lower revs to match what you are looking for.

    Even after it "drops of a cliff" it still has more torque than the S63! Lol!

    It's probably better to have 2x the torque than have a better curve on paper.

    Sorry but, zero bias has ever been put into anyone. Once again, no need for a JB tuning up to the oem tmap limit. Running past that with just the dme can be done but its not the right thing to do and not recommended. Given JB logs timing corrections now across all cylinders we will happily tune anyone with it that needs to use it, i.e. go past the oem tmap limit with boost. Customers need an AP to load our custom backend flashes that's all.

    No bias has been sold to me, nor does any exist, we have chosen to use what works up this point, lets not forget we made 725WHP 2 years ago, with literally thousands of pulls over thousands of miles, MANY 3-4-5 shifts to redline with 30 psi to redline at those levels, that car, same motor is still used a daily driver / commuter without a problem, so when someone says a flash only car will not last a single run at the drag strip or 1/2 races you can see why we take that with a grain of salt. Back then using a JB without 1-6 monitoring would not even be considered, but now that it does, its exactly what you say another tool, and can be a powerful one. The main thing for me is, I find it hard to swallow losing my Canbus as I used my AP daily for a very accurate monitoring tool of any 6 parameters I chose, maybe the JB mobile will help ease that loss as I feel naked now when doing pulls. I will do my best to find a longer test road and see if we can get some 4th gear pulls in. I refuse to get involved in this Jb / flash battle, so if people want to, go ahead, but leave us out of it.

    Im surprised your wasting your time on this guy Terry. Get the JB back as he's clearly not worthy. He says he doesn't have time for forum BS but he's the instigator 99% of the time.

    I think Dzenno is a cobb magician but you gotta let go of whatever bias he's put in your head to get this working properly stacked imo. It's not all doom and gloom or dirty or unnecessary or anything that might have been reinforced repeatedly. It's just another tool to get where you want to be, one that once set is much easier to adjust. Then again I really have no idea what's really going on but the forum stuff is cray. Broncos and Texans won ya'll be happy! Oh wait you are all in Cali, that explains the aggression.

    vasillalov replied to a thread O2 Codes in N54
    UPDATE: The logging did not reveal anything out of the ordinary. So I took my car to the track, aka "The Proving Ground" :) and after two solid sessions of 20 minutes each I was finally able to break something. On the third session the car misfired, thew a bunch of CELs and I brought her into the pits. Quick scan revealed that I had a misfire on cylinder #5 . This is what I've been waiting on for a long time. The fuel injector on #5 cylinder was the last one that I was waiting to fail before I replace it with the updated gen 2 injectors (261-11). The injector was leaking so badly, that my car threw an "O2 muddled" error code. Yet, there was no misfire till yesterday. Long story short: I put in a brand new injector, coded it in and the car runs smooth as butter right now. No more idle misfires during cold start, no more O2 CEL, nothing. So I guess this could serve as a good example of a case where a bad injector was causing O2-related CEL but yet no misfires. I have not followed up with the recent developments in the piggy back tunes, but I suspect this sort of thing would have been unnoticed for a long long time if CAN-clear functionality is ON in a piggy.
