hello people.

well my Ty is getting tuned now. so far i have like 0 knock. but while it shifts or goes into lockup i get MAYOR KR. near 12KR. my knock sensor is relocated to the lower intake next to the thermostat.
my stock sensor that is on the stock location is broken, and i don't have a spare one to see if i get better readings there, altough i doubt it since it's even closer to the tranny.

thanks!

Depends on what it looks like. I'd take a look around for a mount or pipe that clangs into something on the shifts.

Just after the shift is the max load point, where it's more susceptible to knock.

Pull 2 degrees at wherever your pulldown RPM is, and also at the max RPM before the shift. If your KR goes down significantly, you'll know it's something real.

it has like 0 knock at 14psi. shift. =>10KR and than goes back to 0. lockup 4KR than back to 0.
i don't get knock at the first shifts. only 4 and lockup.
i have solid mounts as well.
if i do this in D i have less knock.

well..i hate them as well, but it comes in handy when changing timing and feuling etc.
just wonder how did you get it tuned without a KS?

Spark plugs are the only true way to tell... even more detailed than the knock sensor. Outside of a high-speed cyl pressure sensing outfit, that is.

The real sucky thing about our platform is that plug checks are a royal PITA.

ok dumb question what happens if you unplug the sensor. Will it go into a preset retard mode or just not read any knock. I run a Big Stuff 3 in my TY so i never tried this. I dont use the knock option in the BS3 either. Anybody try this???

on a stock ECM it will. it will pull 8% of timing i think.
