The FS2 HHO Chip reads the O2 sensors along with about 5 other sensors.
So, you would not use both (can't).
Yes, we sell the complete kits, for your vehicle, it is the S-7 Hydrogen Car Kit.
If you wan the FS2 HHO Chip then get the "Bundle" if you only want the EFIE (instead of the FS2 HHO Chip) it is the same price as the S-7 Kit "bundle".
Please email hho@hydrogen-generators-usa.com for if you have further questions. You may also get a quicker response.

ML 320 by: martin oviedo
Hello
Yes, it's a ML320 2002, with a 3.2L v6 engine(gasoline). I been reading about the efies. First, in the case of the FS2 I read you already program them with the car specification, what abaout the Quadband? whats are the differences between them? besides the price. Do you sell the complete kit?
Thanks

Hello,
Yes it will work, the only vehicles we have not seen success with are hybrid vehicles.
You don't say what year your Mercedes Benz ML320 is but if it was built after 2000 it is a wideband.
So, your Mercedes Benz ML 320 would need the Quad Wideband EFIE, or a FS2 HHO Chip.
