KS could be an issue if its on too tight. I would clear the Code 64, re-install the - BATT cable. Then turn ignition ON and rap the block w a hammer. See if you get a code. The Moates daughter board does not bypass the KS circuit on the memcal. It is used to bypass the OEM prom.

I bought one in December for my 1990 to cure a problem, but found out the cause was not the ECM. It is a remanufactured one that I bought off EBay and had it too long while the car was in the shop to return it.

Are you still interested?

How much do you want for it?

lfalzarano · 07-09-2015

I have the receipt in the garage, but I will try to retrieve it and reply tomorrow. The Vette crushed my foot last week trying to push start it, so I am not really mobile enough to make the trip.

I believe I paid between $600 and $800, but will sell it for what I paid for it.

You still interested?

Is there a torque spec for the KS?

A 1990 factory service manual says; "Do not apply thread sealant to the sensor threads. Sensor is coated at factory and additional sealant will affect the sensors ability to detect detonation. Torque to 14 lb. ft.".
