Way to go Matt, 14 PIDs is plenty if you split your tuning into section fuel then timing. What happens if you slow some down some of the PIDs like the fuel table selected, engine coolant temp or really any of the status monitors, could you increase the number of total PIDs, or just gain resolution on the others.

It looks like the two fuel maps are for Open loop and closed loop. Is there a PID for open/close that you can monitor or is that the same thing as your fuel table status. The switch between the two tables is based off of load or change in throttle percentage? I assume you have two timing tables as well that follow the fuel table switch. I think that the NSX ECU may have at least two more fuel and timing tables to deal with Vtec. Is there a fuel or timing modifier for VIS in the Legend?

Sorry for so many questions but the OEM ECU tuning strategy is very interesting to me.

Very cool to see your project progress, I would love to see this setup make it to market.

Have you come up with a solution for boost yet? The holy grail!
