No, Joe, I haven't done this for my ECU nor any other because it made no sense to me to do it. It was much more straightforward to build a Megasquirt, which provides me with all the tools to tune the engine properly. I had to do some engineering to stuff it into the box and to make the stock sensors work properly, but I was lucky that my car already had everything I needed (some cars would be more of a challenge). Add a wideband O2 sensor and a PalmPilot, and test days double as tuning days. [/b]
So the answer to my question was yes then you have a megasquirt stuffed in the stock box? So you are arguing from the stand point of someone that has already exploited the rule as written. I am sure there maybe a way to turn the airbypass on in a stock ECU but I am also sure nobody has done it with the software available currently to burn and prog these chips. I am also certain that none of the current factory ECU's have the hardware to handle TC of any kind internally. The current 350z uses a completely external ECU to handle is VDC and TC functions. All of this has been stated before so I will wait and get the letters written against open ECU's and Open harnesses when the time comes. I believe tuning the factory stuff is well with in the philosophy of IT and I will stick to that.
