2019 civic SI. My state only requires monitors working and does not sniff the exhaust for emissions. I am designing an o2 simulator for the downstream sensor so that I can run my downpipe and pass emissions. Since I am modified already and can not get the proper readings, can someone provide me a graph of the AFR voltage, secondary o2 voltage, rpm, and throttle position? need a warm up, cruising at steady rpm, blip of the throttle and coasting. With this info, I can design the circuit required. I am close. designed 1 circuit, with my only engine code left is slow response. Can any of you help? I will be sharing all my progress.
