Hey everyone. Just installed a chimera intake, full yoshimura rs-9 exhaust, and PCV on my 2015 grom. After installing power commander with yoshimura tune it seems to run much smoother with better response but seems like I lost some mid range/low end torque? Read I should reset ecu before installing PCV and try two brothers map. Anyone have any experience with this? Can I reset ecu with power commander installed or do I have to unplug it? Any input is appreciated

Im relatively new, but I believe you can just reset the ecu with the PCV still plugged in. Thats how I have been doing it. I heard you should do the ecu reset any time you add anything that alters air or fuel.

Cool thanks for the reply. Wasnt sure if I could leave it plugged in or disconnect beforehand. Hoping ecu reset with two brothers map feels better
