Haha thanks!I actually filled up with 87 by accident, and that gave me the reason to make this video!There are 3 modes of communication all built into the ECU from the factory and software selectable - a two way request/receive mode, a one way 66 byte stream and a one way 16 byte stream. The 66 byte stream is what comes out of the ECU in its stock form and its a bit slow for updates (about 1 per second). In the video above I am using the 16 byte stream which runs pretty quickly as you can see! There is a list of memory addresses for the stream within the ROM chip and I have the memory addresses custom modified to suit my needs above. The Tunerpro definition file correlates directly to this list of memory addresses.I would say the ECU in its current form is cracked enough to do some serious tuning. I am heading down to Englishtown this weekend for the National Acura Legend Meet and will hopefully be on the dyno to do some preliminary tuning. Time has been my major limiting factor. My shop has been unusually busy for the summer months.The two major things left would be to find the fuel multiplier values to compensate for larger injectors - and some custom coding to support boost (I need a turbo on my car first ). I honestly don't even know where to start with modifying the code to support boost, I know the main thing is to hold the ECU in open loop once boost is being produced. There are other things I'd like to find such as coil pack dwell time, etc.-Matt
