I have a stock b16 and I am planning on putting ITR/CTR valve springs and ITR/CTR cams in sometime this summer. I was told I could swap out my P2T for either the PCT or P73 with no problem (granted they are obd2b).

My question will I see any difference between these two ECU's?

The more info the better. Thanks

 

fuel and timing maps are different. pct has a higher redline and later vtec activation ( I can't remember the specs)

Both ecu's
