Hi everyone,
I installed a Yoshimura full exhaust system, a Dynojet PowerCommander and a Dynojet AutoTune on my Honda 2019 CRF450L.
This is the international model which has an O2 sensor. When installing the AutoTune, I removed the original sensor, disconnected it from the harness and installed the new one that goes into the AutoTune module.
The problem is, I now have a check engine light. A quick fix would be to plug in an O2 eliminator in the harness and let the PCV + AutoTune do the magic, but I can't find an eliminator kit for the CRF450L and Dynojet now tells me I should run both sensors, which seems ludicrous. I understand they're being sued by California because their products challenges emission legislation.
This is not practical and I need a way to trick the stock ECU to turn off the check engine light. I just tried a DIY method soldering a 2.2k ohm resistor at the end of the stock O2 sensor connector but it hasn't yielded success yet.
Does anybody know of an eliminator that uses the CRF450L O2 sensor connect pictured here? https://ibb.co/xL063bR
Any help is appreciated. At this point I'm getting a bit desperate and considering just getting a Vortex ECU by Tokyomods. Thank you!
