Hi, have you experienced any problems with cork as spacers/gaskets? At a local hardware shop at Margate they thought that the cork might break down in a caustic (KOH) solution. I'd appreciate it if you could mail me @

My engineer knows what chip it is I can ask him. It connect to a terminal strip on the top of the case. You have to run the wires from your o2's to it. Later I will design one that you plug into your obd2 port. The cost is $250 for a 2 o2 unit and $300 for a 4 o2 unit.

Sorry, only you can see it? well I`m not good on pc, and this is the result, by the way I also designed one (effie) I call it as oxigen sensor controler,what I did
by using a chip,I pinch 0.2 volts from the sensor and it works from top ().9 v down to 0.2v, later I will send a pic.

You should put that in the Break the Ice forum. Only I would see that message. Good to have you on board.
