obd1 jdm b18c, my car keeps throwing a knock sensor cel. it isn't predetonating, guessing bad sensor. sensor is $240! i have seen differnt eprom chips that elimate knock sensor. are there any other other options, and are these chips legite?

 

You can get them for $30-$50 on Ebay.Thats your cheapest/best way to cure your issue with out adding other issues.If you want more flexibility in your engine management go directly to the Hondata s100 or s200.Stay away from the "mugen" chips.
