S300 V2 closed loop Problems

[Lyle_57IAL]

Hello hondata !

Currently i am using the P28 S300 v2 on my 92 - 95. 2.3.3 Software version. Currently i am using my innovate LC1 wideband o2 Sensor and data logging back into hondata. I really want to be able to use the close loop feature for all my fuel mapping under boost - Keep my fuel mixtures nice and constant / clean etc. Currently Using D14 to Log my widband scaled at aprox 0 - 3.7 volts.

However whenever i enable to close loop the car simply will not start. And if the car is running with open loop enabled - and then i enable closed loop it will stall the engine. I really want to be able to use this feature - could you give me some pointers about where to start?

Thanks !

To get proper wideband reading it's best you use a input other than D14

Also double check your wiring: http://www.hondata.com/help/smanager/ecuconnectors.htm

My Wideband reads & logs perfectly back at the hondata dock. I did not loose any resolution on the sideband input as i only scaled it to 3.7v = aprox 17 AFR

Anyway i don't understand why the open loop feature is behaving this way ?

Try moving it to D10 instead.

No my ecu HATES D10 ELD. won't ever work - just simply wants to turn the car off.

Please any feedback

Don't use D14. Use one of the other wideband inputs on the ECU.

Ok seems to be behaving a little better - I can get the engine to stay running with closed loop however is there anyway to not have closed loop enabled at idle? Massively stuffing around with my mixtures on a hard file to set ( large tb, large cam, big injectors) etc

No there is not.
