I wonder what sort of tests MetroMPG will come up with using his new logger? Any plans yet?
  • - It'll let me look more closely at things like my hot air intake. I've never been satisfied that my HAI seemed to produce no favourable results, because the theory is sound. With this unit I'll be able to see immediate changes (if any) to timing advance, throttle position and fuel trim and maybe answer the question as to why it didn't appear to work on my car (and maybe make it work).
  • - Same thing with adding more EGR. I could theoretically idle the car in the driveway, run a hose from the tailpipe and introduce exhaust into the intake and watch the sensor results live.
  • - Last winter I was also talking a bit about spoofing the coolant temp sensor to achieve closed loop operation a little faster. This would let me view and log the results of that.
I'm sure I'll come up with more things to play with once I see what it can do...
