Hey guys I've got a b18c turbo running a hondata s300 v3 with pwm enabled.
Car has a brand new plx wideband wired into d14 (factory 02 sensor wire). Wideband reads same as ecu, gauge and datalogs, but when we try enable Closed loop the car stalls (lean) and dies immediately.
We checked all the wiring and are completely stumped as to why the car won't run closed loop.
I don't have the factory o2 plugged in, furthermore on a p72 gsr basemap the car was running closed loop (d14) without stalling but as soon as we load our turbo map closed loop doesn't work.
Anyone experienced this? Any ideas on how to get closed loop working?

Re: S300 v3 pwm - unable to run closed loop..engine stalls immediately
You'll have to play around with the "rate of change" table on the closed loop tab. You should switch the wideband input to D10 and cut out R136 and R138 from the ECU, as D14 doesn't have the full 0-5V range needed for the wideband input.
