End user OBD tool/reflash

Planning on buying a M6 GC soon and wonder if it would be possible to get a flashing tool (end user) trough OBD port? If yes, who makes one and pricing. Please share names and links.

I plan on adding catless downpipes, drop in filter and stock exhaust. Wonder if it's worth doing Downpipes?


Thanks a lot!

Nothing? None available? All have to get the ECU removed?

I personally run JB on mine, its plug and play kit. Never had any issues with it at all.

I would recommend catless downpipes, possibly pair it up with nice exhaust. The spool sound is simply amazing. But you will get that catless smell at idle.

Does the STG 1 JB4 work with catless downpipes? No CEL?

BMS is actually working on that since the last time I spoke with them. As of now, CEL will come on even with the JB on the car.

Nobody can currently flash via ODBII. It's either a piggy back box (BMS) or have your ECUs removed/flashed/reinstalled.

The piggy back works well especially from a "bang for your buck" standpoint. The BMS will also control methanol if you go that route.

The safer and more efficient way would be to change fuel, timing, boost, all within the ECU of course.
