91 civic with s300 and cable tranny won't show vss

[doc_763]

91 civic converted to obd1 with hondata S300 v2 and I am still using the cable transmission. I have vss signal wired to b10 on po6 obd1 ecu vss signal input from my original cable input speed cluster. My vehicle speed is showing up on my plx r500 and matching the cluster speed. I have signal at pin b10 on the ecu and it is alternating with speed on cluster increasing and decreasing but it is not showin up on s manager software. Can anyone help me with this issue. I have checked and double checked all settings and parameters in s manager and everything is okay. Can anyone help?
Thanks

If everything else is reading and the software/ECU is not seeing the signal then it sounds like you either have it wired to the wrong input, or the ECU is faulty. This would have nothing to do with the s300 itself.

Is there another input i can use on the ecu for the vehicle speed sensor input rather than b10. I am using obd1 ecu.
Thanks

[Spunkster]

No there is not.

[doc_763]

Is vss a linear input?

[doc_763]

Would the removal of resistor r136-r138-r2-r3 have any effect on the speed?

[Spunkster]

No, those resistors have nothing to do with the VSS.

[doc_763]

Where can I enable or disable vss on s manager software

[Spunkster]

There is no where to do this it is always working.

[doc_763]

Is there any facility for am aftermarket vss or would settings be causing my problem

[Spunkster]

This has nothing to do with settings. As long as an aftermarket VSS sends the same signal as stock then it should work with the ECU unless the ECU itself is damaged or you are inputting it into the wrong input.

[doc_763]

I am inputting it into b10. I will try again tomoro and post my findings. Thanks again.

are you still running the cable VSS cluster? if you are theres a chance a trace on the back of the cluster is burnt out. happened to me so i went with a 99 Si cluster and OBD1 VSS. hope this helps.
