Thought for the day.
When my ECU makes it back I've decided to stop being an idiot and get the cylinder O2 stuff working so I don't need to guess and touch pipes. The very worst case is I'll be able to narrow it to groups of 3, but I think I can pull cylinder data from those sensors without need to install sensors on each pipe...but the bungs are already on the pipes if I need to go there.
I know it's a PITA but if you can track each cyl... then do it. You've got a major prototype build on your hands with untold hrs of development and design. you'll only be kicking yourself and doing it later anyways.
Here's the question that'll make you think... so with the ability to tune each cylinder individually and get each one to burn efficiently are they all producing the same power within a narrow margin? the only way to answer that is to monitor the intake air mass accurately as possible otherwise it's an avg. How close is each to the next? hmm I guess pressure transducers and exhaust gas temp probes could answer that one.. boy talk about falling down the rabbit hole! Yeah I think you'll be fine with monitoring the burn for each cyl and avg the rest.
The real big question is this though... How are your going to keep your mitts off it once it's running? you know the "I can do it better if I did this" or the "I can improve that!"
Don't say it won't happen... look where you are now neck deep in a custom V12!!
Glad you're making progress again.
