Lets talk tuning, piggy back vs ECU flash.

Only one diagnostic device can run at a time. If there are two devices with the same diagnostic ID on the CANbus the JB4 will shut down it's CANbus to avoid problems. It's not possible to run two OBDII devices simultaneously unless we were to make some special JB4 firmware that ran its sampling rate at a really slow speed which would then compromise the tuning.

How? and Why?

So you are saying that we cannot plug one of these in, and monitor on two devices at the same time?

I really had to hold back from passively insulting the guy as he's a customer after all. And probably just doesn't know better. But sometimes I wonder about these people though. I chalk it up to being within 100 miles of JohnB as he has that effect on everyone around him. :)

While I do appreciate you not passively insulting me because I didn't know the sampling rate of the JB4, I haven't been biased to either of you ever.

I'd love to get some actual value out of ANY of this, so I'm doing my best to offer that for people who want the same. Chill out on the blood war.
 

Right, that won't work, if you are transmitting on the same diagnostic ID which all devices have to use fro the ECU to answer. If the device is passive only (no transmission) then it would work. As soon as you went to transmit the JB4 would detect another device on the bus using the same ID and turn off. If you were to reassign your ID somehow and the ECU decided to answer, since we're soaking up data from the DME's diagnostic output literally as fast as it can give it to us, it would result in tuning issues on our end. For someone who designed a flash tune you should understand all this?

My suggestion: Provide the PID and formula for any parameter you want logged and I'll add it in to the JB4 firmware for logging.

So exactly how many forums have you been banned from John? And all of the bans were just because you were an a**hole as you stated? ....:) Wash
 
Data presented is always based on the credibility of the person sharing it. Whatever data he comes up with he will ensure is bad. And he won't be able to use his logging tools with the JB4 attached to the OBDII port. But more to the point in my eyes and in the eyes of many in this community, whatever credibility he may have once had, he's frittered away in the last few days with his half coherent and misleading anti-JB4 rants. While his posts often embarrass himself, and lower the IQ of those of us forced to reply, the real victims here are his two customers duped in to liking his posts, no doubt so their technical support from him will continue. :)

And we have more insults getting thrown our way, lol.

It sad that you have to resort to that method of advertising, to sell products.

Given time, people will start to report back on the issues with the piggy backs. The purpose of this thread was to compare the two, and share a little knowledge. It would appear that the community is already divided, and lines have been drawn.

We will keep doing what we do, you keep doing what you do. We will let the results speak for themselves.

I 100% agree that our testing ends in a blown engine, that is the purpose of a test/shop car. Do you think AMS, ETS, English Racing, or any other speed shop sets records without an engine failure?

So your good being known as the guy who makes stuff up, avoids questions when called on his BS and fails at reading comprehension on the posts he does respond to?

I have been removed from 3 forums as a vendor, and 2 or 3 more from not being a vendor. Two of them I can now post on, so... 5 total.

Not sure where you are going with this, but... I can tell you it has nothing to do with scamming or unethical business practices.

What question did I avoid? What BS was I called on? What stuff did I make up?

If you made I post and I missed, apologies.

Remember this comment the next time you go to post. It’s at least the 3rd time you’ve said that your done discussing this.

You posted that JB4 blows engines/turbos, I asked for proof. You said, I’ll let others share. Then posted someone commenting about cracked plugs.

Post proof that JB4s damage engines.

More bullshit. BMS has never been banned for unethical behavior. Our vendor account expired on that bimmerpost forum years ago and we did not renew it so could not reply to that other vendors claim in 2012 that we "stole" their photo for a $10 part in an eBay product listing. Ironically that guy didn't have a vendor account to be posting on that forum in the first place.

I think it was stole their product design, fit and, function, but the post is there just look up "burger unethical vendor" in Google or check out his BBB

The fundamental issue is two devices can't operate from the same diagnostic ID on the CANbus without interfering, and the ECU only replies to one ID. Even if you could rig it then the sampling would be an issue.

I offered a suggestion above that would benefit the community. John claims our tunes are knocking, adding timing correction and/or ignition timing logging on cylinders 2-6 to the JB4 data set would prove or disprove his point. He claims to have these IDs although I kinda doubt it, he's never shared a log showing them. If he had the data he's be putting it in his signature and shouting it from every roof top.

Why would I provide you with anything at this point? Not only that, you were the one boasting about 2 decades of experience... why would you even have to ask me to provide you with PID's and formula for logging?

Quite hard to PROVE anything since most will remove the jb4 and act like they have no idea why the issues they had occurred. Like I said so far there have people who have had issues and they have had the jb4 installed. Issues that can arise from over boosting, too much boost. Shitty plugs, lack of gap etc... how many people have had ANY engine issues with ECU tunes be it Tork or Pressertech????

BMS handles around 100 shipments per day and has been for over a decade. Compared to other companies our size we have an excellent reputation and rarely is there an unhappy customer. When unhappy customers turn up we do our best to make them happy.

Meanwhile search "John Bushbaum Scam" and you'll see the sort of business you're dealing with over there.

According to you every JB4 customer would look at their log and see nothing but continued engine knock on cylinder 2-6. What a great marketing opportunity? Surely the reason it's not there now is we're trying to hide things from our customers right?

Is that what you use to justify the no response from the BBB reviews? Too busy?

You could asked in a way that would been in line with your supposed motivation, not suggesting In a way that presumed you knew something and Terry didn't, when you clearly didn't know what you were talking about.

Just last weekend we had a post about a JB4 customer who then recanted everything he ever had on his car.
Terry just admitted to cracking a plug xx number of days after he started working on it, blamed it on the factory spark plugs, lol.

There has been a few posts made, but... there always seems to be a reason or excuse that get made about "more proof". I cannot make people come to the forums and say, "hey, this module is shit". Just the other day someone was complaining about a check engine light, took it off the car and went to the dealer. I had a customer drive from Saint Louis to get a tune and have his JB4 removed from his car, caused all sorts of problems for him. Its not my job to make this people come to the forums and share with you. They are out there, and they have made there posts on social media about the issues that they have had.

You don't have to believe me, and you don't have to believe what people say on social media about it... when someone posts a picture that says JB4 sucks, then has a picture of engine oil all over the driveway, that should be a good indication that something is wrong. But I can see it now, Terry will spin this, and make it sound as if I paid him to do it because he lives 1000 miles away from me.

You don't have to like it, but you have to at least acknowledge that there are some issues with the boxes that people have posted about.
