Shifting gears while datalogging lambda??
Posted: Thu Apr 27, 2006 6:59 am
A couple quick questions:
1.) Do you only datalog while increasing throttle (i.e. never let off the throttle while datalogging)?
I would think so as suddenly letting off the throttle would average in misleading lean numbers.
2.) Do you stop datalogging when switching between gears?
This is what I do now and it is a pain while doing street-tuning:
Let clutch out with gear in 1st > Start datalogging > Gradually increase throttle and load (as best I can) > Stop datalogging at relatively high load and rpm > Stop datalogging > clutch in, shift to second, let out clutch > Start Datalogging again, averaging in values for 2nd gear > etc for 3rd, 4th, and 5th.
Am I going way too in depth on this? Does Hondata "know" I am shifting between gears? Thanks for the help.
