Hi! I want to tune my sti on dyno I want to know what would be the best between afr and egt for each cylinder trim. Maybe if i start with afr and after that i install the egt sensor would be the best? And what would be the pro and cons of each?
I find individual EGT useful as a diagnostic tool. Got a misfire -- look at the EGT data and know exactly which cylinder is the problem. For tuning, you can dial in any cylinder-to-cylinder variances using EGT. I find the 02 sensor (one per bank) is generally all I need to get most engines fueling dialed in, but one per cylinder would give you some additional insight.
