i have an lc-1 . its awesome. but. i am running the log works program and it is showing 700 threw 800 when my car is off and sensor is on. no idea why . its off the chart.
i hooked it up . but i havent turned the car on yet. i am not taking it out tonight. but i was just making sure the program worked and my serial port to usb adapter cable worked for the program
i have the lc-1 hooked to the addapter and hooked into the usb port. program recognizes it fine as com6.
i am reading the manual for the program. its a bit more confusing then the manual for the lc-1 itself.
so is there a quick fix to this issue of it being really j umpy between 700-800 a/f when car is off and sensor is on?

note: lc-1 is on, car is not running. warm up sequence was finished. sensor is warmed up, left on only long enought to show that i was connected and showing data to computer. sensor turned off after 5 min or less.

note : running windows vista

 

did you calibrate it?

 

the sensor is calibrated yes. but i am not sure if theres a way to calibrate the logworks program. i can re-calibrate it. i am getting no error signals from the lc-1.
when its connected to the computer it slowly blinks in no error code pattern..

i followed all exact instructions when installing the sensor and calibrating it open air.



edit. i recalibrated 3 times till it finaly stayed at 20.8%

not real sure if this is acurate. or if i need to really do it "open air" cuz the car has been off for more then a day. and the ratio is steady at 20.7% 20.8%



problem now is that it wont show the needle..................

 

20 sounds about right after calibration. once the car starts it should read fine. the needle "LED sweep" will work also.

 

11-12 idle with bad tps and advanced by 10 timing.
