Monitoring knock


Recommended Posts

How do you TGP guys monitor knock? Can it be done on a per cylinder basis? If the computer retards ignition timing during a run, is there a way to monitor that?

Yes and Yes. A software and hardware interface called Diacom plugs into the diagnostic connector under the dash and you can monitor both those things on a cheap laptop (Diacom only requires a 286 I think).

 

I haven't kept up in the past year or so, so there MIGHT be freeware programs for this. I know some people were selling interface cables awhile back for $20-50 that work with most freeware/shareware programs.
