    I don't want this to be a "let's everyone piss on Shiv" thread. I know that isn't what you are doing but I just want to point out unlike the other threads I want to maintain this one as being constructive since Shiv is taking a civil tone (for now).

    Cheers,
    This is true, 500 whp through the entire powerband and no misfires.

    My belief and that of some other tuners is that this is all CPS related. Terry has induced misfires by messing with the CPS. I believe the connection is clear due to how what offsetting does the ECU.

    Ask Ultimateracing335 about his top end misfire when he was running the jb4. No CPS offsetting there. And a bit shy of 500whp. On the dyno and on the road.

    so was his 511 and other 5xx runs with v5 or with jb4? because i have plenty of questions about those runs..

    v5. I don't believe he ever broke 500whp with the jb.

    so, after i just uploaded them to the dyno thread, i noticed that it looks like he was having some major issues with those runs.. couldnt rap it out past 6200 rpm, and the ones that did.. uh.. looked like something was going on.. care to elaborate?

    Damn 500whp throughout the ENTIRE powerband thats pretty crazy, Ive never seen a dyno graph like that. Sticky do you have any proof that the misfires are definitively CPS related? I imagine you have pretty overwhelming evidence to create this thread and promote it to the front page and all. No way thats only based off your belief and other tuners who haven't commented on here right? I'm pretty sure you can induce misfires by messing with anything enough as Terry pointed out in this thread.

    Yes, above 500whp, he was getting ignition break-up. Up to 470-480whp, no issue. With either tune.

    Didn't you have a 504whp run or something? One that tripped the overboost limit before the run finished? Could you post this?

    ignition breakup? is that a more technical term for something else Click here to enlarge

    yea, 502 when it tipped 21 psi, the boost failsafe limit. it is posted in my original Rb dyno tuning thread here, but that wasnt ignition. you can see in the LOG that I attached with the pic, that boost jumped right then and there with that 502 bump. nothing to hide Click here to enlarge

    This was the last run we did remotely before giving up to address the fuel situation. I believe this was on pump gas, single nozzle, 70/30 mix, etc. No real effort was made to optimize power or power delivery as the focus was purely on fueling. I also put a couple runs from around 17psi on there as well for comparison. The first I heard of any misfires with it was when Shiv was doing the pulls and it seemed more of an aberration than anything. But at those power levels there are clearly many things to address. Fueling and ignition system strength being among the the top of the list.

    As I said before misfiring is a symptom that can come from many sources. None of this explains why 15-17psi stock turbo cars are misfiring.

    I think you are correct that if pushing the factory systems to the limit you could run into misfires although I have not spoken him. Would not mind his perspective. It's not like every misfire ever recorded in the history of the N54 can be attributed to the Procede, just the majority.

    Well, the evidence is rather overwhelming in my opinion. We have BMW tuners all saying the same thing. We have knowledge of what delaying the signal to offset can do. We have evidence of CPS offset cars running the Procede misfiring. We have evidence of BMS inducing a misfire due to CPS offset. How much more is really needed? Come to your own conclusion.

    Look at all the factors that can cause a misfire and you will know what can induce a misfire. Shiv himself has mentioned some of those. Let's not make it seem like the only way to cause a misfire is to run a Procede as that is ridiculous. However, there is a constant of CPS offset cars having misfires.

    The last time I announced a trip to NJ, you publicly threatened me with your guns and got banned from e90post for publicly implying that you would shoot me upon sight. So forgive me for not wanting to come face to face with your sociopathic nutty self. So you want to run a v5, purchase one, install it, and run it on the dyno. You will likely make more power than what you are making now. That's pretty ballsy asking me for a custom tune. You really are crazy, aren't you? Click here to enlarge

    This is why I was asking. "WE BMW tuners"? Honestly I only see you saying that on here and I remember reading you post a few weeks back if it was hard to be a tuner. That is why I bring up the question, because although you have hinted that some unnamed BMW tuners have told you what they think they have not posted on here or shown the slightest bit of evidence. If you had some runs from the same procede tuned CPS offset car misfiring and then disabled CPS and ran it with no misfires I would be far more swayed.

    I agree that Procede obviously has/had a problem with misfires as I found a few threads about it within the first few pages of that bimmerpost website. I just dont see any evidence. X car runs CPS offsets and misfires therefore CPS offsets cause misfires as "overwhelming" evidence doesn't pass the common sense test for me. For example I also saw two threads about JB cars that blew their engines, by your standard of evidence I could reasonably conclude that JB tunes cause blown engine(I dont as that is absurd) Just saying lets seem some factual evidence other than the opinions of faceless tuners before we jump the gun for headlines no?

    That was actually a typo, we "have" BMW tuners is what it should have been, corrected.

    You weren't here for the last time the topic of misfires was brought up and it just about caused World War III. Trying to get this information is dificult as yes, you would be swayed if a car had CPS and misfired and then disabled it and then it no longer misfired. Pretty clear cut right? And who is going to agree to this? If that is the case (which I believe it is) then all it does it hurt Vishnu's market perception. Now who will participate in that? Just showing a video of the misfires taking place caused chaos: http://www.bimmerboost.com/showthrea...light=misfires

    You know they are taking place, as stated and shown with evidence. There are also hints that disabling it has been tried. Well, if no one thought it was a culprit why even bother with disabling it? Well?

    I would say keep reading but unfortunately you may be reading in the wrong place.

    No, that is by your standard of evidence. To be honest, those are all old topics and although I realize you are catching up on this you should know those issues were heavily documented on several forums.

    I don't think there is any jumping of the gun here, this issue has been allowed to play out for some time while information and feedback was gathered. There has been plenty of time from when the correlation between CPS offset and misfires was first hinted at until now and I believe we have done our proper research. This thread was also forwarded to two tuners with an additional two reading it now and none of them except for Shiv have had any issues with it so I stand by it. If I was not prepared to, I would not have put it up.

    I believe a more accurate description would be to say this is being brought to attention way too late not way too soon.

    This response above was posted by you 24 hours ago. You had never even heard of the CPS being disabled and didn't even know it could be done!




    You'll have to ask Shiv that. But I heard they've been bypassing it a lot lately. Click here to enlarge

    This response was by Terry from BMS. This is procede's DIRECT competition stating more admitted hearsay. I wonder if they have anything to gain by "hinting" at the danger and uselessness of a feature offered by the competition and not by them, a feature that they have "spent several late nights" in their words trying to emulate. HMMM this is why I'm doubtful about the extent of your "RESEARCH" into CPS, your basically repeating and even worse expanding on what a competitor/vendor hinted at and labeling it fact. It does a disservice to the BMW community to dismiss possible improvements for the wrong reasons. I have stated on here I am not a supporter of CPS or any EMS(except HALTECH) but if we rush to vague conclusions we may miss out on improving the offerings for these cars. Honestly if Shiv came on here and said "Yes CPS causes misfires, I tried it because currently BMW piggybacks have no timing control and for anyone familiar with tuning this is not acceptable" he would get my business because I prefer that to someone who is content with the status quo. Its the same as with my BMW, there have been many issues with my model of car(HPFP,ARS failure,Fuel Level Sensor) and the damn things just came out. I accept this and chose to buy these cars because BMW is on the cutting edge and thats where problems occur I support that and we are not even sure that is whats happening here.

    Ya... in response to Terry's post that the CPS had been disabled, right? Hence my comment that there are hints of it being disabled.

    And take it as such. That is why I said there were hints, not actual proof. However, Shiv also did state in this thread trying no CPS offset which would lend strong support to the bypass being tried as stated, wouldn't it?

    BMS is going to be offering this feature. They aren't even the ones who have suggested all these issues actually it is users and tuners who aren't eve in the N54 market but who are familiar with BMW dme's.

    Of course, but that is the problem he hasn't done that. Instead of doing the right thing and coming clean so to speak he continues to propagate this safey myth which has been used to discount competitors. Terry on the other hand offers users the choice. Which approach do you prefer?

    This is beyond Vishnu vs. BMS and any of that nonsense and well into what CPS offsetting really does to the DME.

    And what exactly is CPS offsetting really doing to the DME??
    Terry is only in the very early stages of grasping on how to properly implement CPS offsetting against a piggyback that has been using it from day one.
    It's only natural to have a learning curve on a new engine/DME platform and as far as implementation goes, it gets better with more testing and development.
    To discount it's usefullness as a tuning tool so quickly in the infancy of some tuners' testing is very nieve at best.

    It's only natural to have a learning curve on a new engine/DME platform and as far as implementation goes, it gets better with more testing and development.
    To discount it's usefullness as a tuning tool so quickly in the infancy of some tuners' testing is very nieve at best.
    Terry and BMS can do whatever he and BMS want to do. Not my business, not my concern. My concern is to inform users to the best of my ability of the complete picture of CPS offsetting. If that negatively impacts Vishnu, BMS, or whomever else, that is fine if it spares you any potential issues as well as helps you make a more informed decision.

    To consider CPS a proper tuning tool is naive at best. It has been way too long where people equate offsetting to pulling timing. They are not the same thing.
