Hello,

I hooked my LC-1 to my S300 but my gague reads different from my S300.
So far i hooked a 1 kohm resistor to both black wires at o2 connector, white wire to LC-1 yellow cable, green cable d22 on O2 connector routed to a terminal block, with 4 blocks in which i have grounded, LC-1 white cable to one block, LC-1 blue heater to other block. Gauge grounded on same point but different block.

Brown Analoge 2 output to D10 which has been cut in half

LC-1 red wire to a 12 volt from fused box.

What i have tried. resistors 136 and 138 removed. but readings are way off. example gague reads 13.8 and Smanager reads 9 or something.

I wired the yellow analogue 1 output to D10 but its even worst.

I check voltage between D10 and D22 getting only 1.9 V same D10 and chassis 1.9V

Any idea whats missing or what should i tried next??

Thanks

i have no idea what you got going on there but. the gauge/controller should have a 0-5 volt output. run that wire to the ELD(D10) wire of the S300.

-set the pulldown in closed loop tab to D10.
-disable ELD in the misc tab
-in the list of sensors on the left , double click AF , set it to air fuel ratio rather lambda and also set the MIN box to 11 , and the max box to 18.
-click on OPTIONS , SETTINGS , click on UNITS tab. the bottom one , click air fuel ratio dot rather lambda.

now start the car , let it warm up a little.

check what s300 is reading vs the gauge. if its off which it will be:

go back the the closed loop tab in parameters. under the pulldown where you set it to D10 , enter 1 in voltage offset. see what it does. keep changing the value till you get s300 to read the same as the gauge. like for instance , if your using an AEM UEGO gauge kit , the voltage offset for it is -.45. or at least the last 2 cars ive tuned with it were , lol.

i will try that today and let you know.

Thanks
