Shark Injector Review -- E46 BMW 330 ZHP

[danewilson77]

The full-page ad copy shouted, “I will boost your horsepower & torque.” Whoa! With claims like that, I felt personally challenged to test the Shark Injector. It’s an OBD-II connector that overwrites a part of the BMWs DME (BMW speak for electronic control unit or ECU) with its own internal Conforti software to deliver claimed results. So I installed the Shark Injector on a BMW 325i, one of the many six-cylinder BMWs supported by the Shark (includes all sixes in the 3, 5 and Z series BMWs through 2005, plus the M3 and X5 3.0). Or should I say I set about installing the Shark injector…

I've been interested in trying this...but with remarks like, "Assuming all goes well, the programming takes about forty minutes." What if something goes wrong and I have a damaged ECU?

There is a "what if" associated with everything. Take ALL of the precautions the Shark Injector software paperwork tells you and you'll be fine. I attempted to do it with a deteriorated battery and a not-very-powerful battery charger and it wouldn't let me do it. It does have a check involved and checks multiple times for correct battery voltage to prevent an "issue" from occurring.

Got a new battery and all was well with the world.

The only time I see customers with issues with the injector is when the DME has been reflashed by BMW. This is on my list of mods.
