As long as you run the proper fuel, and proper plug with the correct gap issues seem to be few and far between. Im still waiting on flash tuning, which may never happen at this point.I just got a 2021 g70 3.3t Sport and i want to slap a tune on it but I don't know how reliable this JB4 piggyback is, if something happens to my engine I'm sure the dealer will find out I ran higher boost if they look hard enough. Has anyone had any issues with the JB4?

Yep. And if it were me and I was tackling this thread for the first time, I wouldn't tackle it without a cup of coffee and a comfortable chair.Start here.

Since the JB4 is a piggyback it sits between the engine and the ECU. This means the signal the JB4 sends back to the ECU has the OE calibrations. So if the ECU is expecting 12PSI the JB4 will send 12PSI back to the ECU but the engine will actually be running 16PSI. The JB4 intercepts the signals before it goes to the ECU so when the dealer runs a scan on the ECU they do not see the 16PSI they will only see the 12PSII just got a 2021 g70 3.3t Sport and i want to slap a tune on it but I don't know how reliable this JB4 piggyback is, if something happens to my engine I'm sure the dealer will find out I ran higher boost if they look hard enough.

Wow that solves all my worries! because now if the JB4 for any reason does cause damage to my engine the dealer won’t know about the Jb4 if I remove it physically and my warranty won’t be revoked.Since the JB4 is a piggyback it sits between the engine and the ECU.

Hope that made sense

Terry I loved the product on Q60 but it seems even better on this platform. Thanks for your responsiveness in the forum and for making our cars even more heart racing!The JB4 is a fully programmable tuning system. We can set it for whatever power profile we want and with the extra inputs and CANbus makes the RC look like a toy.We provide free firmware updates with new maps, features, and performance levels as we test and develop them.
That said different strokes for different folks. Just remember our customers post ACTUAL dyno charts and detailed tuning data logs to go with them while many other companies just post theoretical numbers with little to support them.

I have just wanted to underline his statement here for anyone with any doubtsHe rarely comes here...you are better off pinging him on the BMS forum.

any guesses on what happened? Im thinking he ran out of meth.Most of you probably already saw this thread on the Stinger forums, but here it is just in case. FYI he was running WMI as well.

Also lol on him not wanting to share how he got it fixed because it wouldnt apply to people here. Yea dude, people in North America are rich/have rich parents too![]()
but how did the exhaust valve break? Something had to be the root cause of that.He shows it pulled ignition timing in that cylinder that had the broken exhaust valve. My guess is the valve broke off and took out the anode of the spark plug. The ECU saw loss of spark path (increased resistance) and pulled timing.
Gap resistance increases with boost/cylinder pressure, which is why you have to reduce gap with boost mods. ECU saw a huge gap when the anode was damaged and decided something horrible was going on in that cylinder so it pulled timing.
I wonder what the exhaust valves are made of, there quite a few alloys, and various philosophies/tradeoffs in turbo engine design. Light/cheap is ideal for OEM, but not so good for mods.

Seems like JB4 safety wasnt fast enough to help.
