Brand New G70 owner - 1400kms done, put my plugs (probably a must) JB4 and CAIs on after 1000km and I've done rest on MAP 2 running 94 RON gas. Hopefully I'm not jinxing anything. Smooth and amazing so far. BMS have looked at small log which was fine.

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?
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.

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.

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 12PSI

Hope that made sense

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.

Why would you expect warranty if the JB4 causes engine damage?

Interested in a tune and some ideas for tuning the exhaust notes for a bit more aggressiveness... I live in Toronto, Ontario.. Any ideas on availability of parts and anyone here know of reputable shops that could install?

Thanks in advance.

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.
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!
