Lap3 ECU tune

[Stingerbuilder89]

It doesn't, because even when removed the transmission computer, stability control modules, and others have recorded true higher than factory torque levels. Swapping the ECU also leaves a trace in the dash module as it re-syncs vehicle mileage between the two.

If you're buying another ECU in hopes it will help with warranty you're wasting your money. The spare ECU is just an easy way to change tuning maps as at home OBDII flash tools have not been released yet for the platform.

Personally the best thing about the ECU is timing

How does a spare ECU swap compare with something like JB4 as far as swapping it out for visits to the dealership and warranty?

I’m unsure what you mean by this builder 89 but Stratford it’s straight forward You just save your ecu put it in a cabinet or somthing and if you have a dealer visit coming up just put factory back in it’s simple as that no crazy wires or anything it looks like this View attachment 54422

This is absolutely true. I am a dealer master tech. I read the question as if jb4 had anything to off in this aspect. Which they don’t.

 

[Stingerbuilder89]

Nope. For better or worse, with a good piggyback in place, the ECU and other modules on the vehicle are never aware they are making more than the factory boost, torque, and load values. So nothing higher than factory is ever stored.How can you possibly say that your piggyback is not changing these recorded values ?? Yet put down”450”?? Sorry. The jb4 doesn’t even have the ability to properly provide the definition of the DTC. How many people have you gotten to fall for this backwards ass thinking?? You know if there is recorded data like you state,,,, then no item available can clear this data. Probably except those who actually can communicate with the vehicle properly as the the factory does have a better chance than bms

You're entitled to your own opinion but not your own facts. All automotive manufacturers use the same basic techniques to detect flash tuning because they all buy their electronics from the same automotive electronics manufacturers. Flash tunes are easily detected after the fact even if flashed to factory and EVEN if you swap the ECU. In this case not only can they detect the ECU itself has been swapped but you'd have to change the computers for the trans, stability control, dash, at a minimum, to try to escape detection. Good luck with that.

There are lots of great reasons to flash your car but doing so makes it impossible to avoid detection later if that is something you're trying to do.

As for the prices flash tuners are trying to get, IMHO, totally ridiculous. For BMWs we publish free unlocked maps for use with the JB4. The flashing tools (MHD for example) charge a $79-$249 fee per VIN for loading maps based on the value of the car. So to flash a $100k M5 is around $249 for the license then whatever you spend on the map. Even custom tuners only charge around $300 per map to make maps specifically for you. But everyone has to make a living and if people are willing to pay their price for disposable flash maps, more power to

where are you going with this a spare ecu is undetectable because the ecu is where the values are stored and recorded. When you unhook your battery, the ecu looses power and shuts down. Then after 12 months on the shelf when you bring to dealer for whatever reason you put your UNTOUCHED NOT TAMPERED WITH ECU back in the car it turns back on and your fine. Btw be carful how you respond because if your going to say readings are recorded Somehere elce you essentially are telling all your jb4 users they just got f&*%ed. Also go lookup and find the codes and code it into the jb4 software it’s kinda anoing having people ask what there codes mean.

I'm not sure I have the energy to correct all the misstatements above but I'll give it the college try.

1) The ECU is one of around 10+ computers (modules) running the vehicle, all of which are connected via the CANbus. Information generated by the ECU (for example, calculated torque) is sent via CANbus to all other modules for use in their operation.
2) The ECU, TCU, ABS, etc, and several other modules store peak values of critical information (such as calculated torque) in non-volatile memory for diagnostic purposes.
3) Disconnecting the battery does not reset non-volatile memory. Even for 12 months. If it did, you'd need to reprogram your vehicle every time you disconnected the battery.
4) Odometer mileage is cross stored on the dash module (KOMBI) and ECU. When they conflict there is a resolution process with the highest mileage getting written to whichever module had lower and both modules storing that a conflict occurred and was resolved. This is all federally mandated to prevent people from scamming odometer readings by replacing the KOMBI or ECU. The dealer can check this and then you'd have to explain why you swapped the ECU for a vehicle that is supposed to be under warranty.
5) With flash tuning ECU parameters being spread around such as calculated torque will be higher than factory levels and this easily spotted when checking peak values stored in various vehicle modules. With a piggyback by design only factory like calculated torque values are passed around.

As I've said all along I'm not against flash tuning. I do flash tuning daily for our JB4 customers. But people need to understand what they are getting in to in addition to whatever tuning benefits are being touted. Unlike a JB4 which keeps all factory safety systems in place, and expands upon them, there is an awful lot of stuff to screw up in flash tuning. Often changes are made that have unintended consequences the tuner has no idea of because he has not or can not test that climate, situation, etc.

Ooooooohhhhh so jb4 users are f&*%ed everyone is f&*%ed oh man gg alll ... to make a claim like this do you have proof?

 

[Utgt1]

So what is being said is that anything that changes values is stored and can be found so how is a piggy back not detectable it has to change values to change boost and afr and such isn’t that stored as well

 

[Terry@BMS]

Ooooooohhhhh so jb4 users are f&*%ed everyone is f&*%ed oh man gg alll ... to make a claim like this do you have proof?

With a JB4 for example there is no trace left behind. Clearly reading comprehension and technical discussion isn't your thing.

Not everything is stored, only key parameters. Like load, boost, calculated torque, vehicle speed, etc.

With a JB4 calculated torque, boost, AFR, trims, etc, etc, all appear within a factory plausible range. No need to take my word for it. Just plug in an OBDII scanning tool and confirm for yourself.

Proof we need proof that jb4 is not detectable please provide some

 

[G70 Owner]

LOL starts the fight by saying he has proof and what Terry says is fake news. Terry provides facts showing he is full of BS. Then he asks for more proof....that he already has but wont share? This is insane

@Terry@BMS dont waste your time. All of us can see these two have no clue what they are talking about

How so you have people running 450 whp so by saying this is detectable and yours is not how do you prove it I want proof my dude backup your claims with actual proof if you want proof of ours I’ll legit go and test it myself.

What did he prove to us. From our point of view we came here to give new information to the community on the lap3 ecu tune. He shows up and tried to answer people’s ? With false information and you expect us to just back down for real ? We are not attacking the jb4 we could if we wanted to but we are better then that. We have no desire to start a war because at the end of the day people get what they pay for.

I just want to see proof but if you want to be terry’s yes man go ahead I make my own decisions and I have not seen any proof a piggyback can’t be detected

False information? There you go again claiming you know something when you dont at all.

1. Even if you were right, the way you are coming off is unintelligent, unwilling to engage in actual discourse and downright rude. Provide me proof? How about do some for yourself or do you need handholding like a child? Grab an OBD2 tool and pull some scans. Look on the damn internet. BMS is not some unknown company doing their first piggybacks.
2. Ive been part of this forum and others for a long time. BMS and Terry has been too. Not a single time have I ever seen a thread where someone had their warranty called into question because they found a trace of the JB4 in the ECU. Terry has been helpful. You and your little troll friend have nothing to offer.

 

[Slip_Angle]

^^ That. Terry's done more for this community than probably anyone else. Debating is fine but the completely disrespectful and rude way you guys go about it, isn't.

Google can jb4 be detectable after uninstall

Now your getting angry again I will replete the same thing I just said terry is saying shit about our product. We have no desire to start a war with him he has his own customer and can stay with them. Friendly competition is fine but when he comes out saying downright lies about a product he has no idea about that’s when you cross the line . I’m done commenting on this post if anyone has any ?ns about the new lap3 ecu tune feel free to send me a message I can help the best I can thankyou and have a great day.

All I asked for is proof but you seem to think you need to answer for terry I don’t know why but okay google says different

lol that more or less sums it up. I don't have the energy to chime into every thread but the nice thing about the forum here is I can set the record straight, and then these posts are here for posterity should someone bring up the same points again or need the same information. These guys tend to repeat the same false stuff over and over again even once corrected.

Our Stinger JB4 has been out since 2018, with thousands sold, so there is a nice long track record people can reference. As I've said before we don't encourage warranty fraud. You should pay for any damage you cause operating your vehicle in excess of the factory specifications. But unlike flash tuning there is no footprint left behind once a JB4 is removed.

If you want to drop $1500 or $2500 or $4000 on a flash map don't feel like I'm trying to stop you. The better the flash tune the better your JB4 will work. And If you can afford these flash tunes you can afford the engine repairs that may end up going with them. But when you start to tell me swapping the factory ECU for a flashed one and back does not leave a footprint that is where it's pretty easy to call BS for the reasons I've articulated above.
