Torque Knock Test
 

I have a Unichip and been running Torque. The other day i found the Knock Detector add-on and tried it out. It almost always said possible knock detected. It's usually -.05 correction out of 15-20 samples(about 10 secs of WOT). Is this normally or should i run a map to reduce the timing? I don't know if the app is reliable or if i shouldn't worry about it.

Thanks,
Joe

I'd like to hear someone with some experience chime in here.

The stock tune is certainly known to be a little knocky, it could be that the sensor is picking up on knock frequently if you're running not-so-great gas.

The Torque App gets that value from the ECU afaik. I don't know much about how reliable the custom PID's are though.

.05 is a wierd knock detection, so i think it is off by two decimal places maybe.

POSTIVE knock correction is good... typically this is called knock learning in our cars and any time you go WOT depending on your tune it should go to 5 if your car is happy.

The other, which is bad is Knock correction CA, if this is incrementing negatively as you go WOT that is bad. A negative 1 here or there isnt bad and is very typical for our cars. If you are increasing to -2 or -3 that is something that should be looked at.

PS how do you add the knock correction pids to Torque?

Go to setting and hit Plugins, then hit Installed plugins, and then hit get more plugins. That brings up the list and you can install whatever from there.

I see the "Knock Detector" plugin although i dont think that is what we really need.

We need a custom pid that monitors the below from the ECU. And preferable something that monitors IAM or DAM

1. Knock Correction Learn Value (°CA)
2. Knock Correction (°CA)

The knock plugin stinks. Has anyone found a PID for this?

@Guff, another one popped up. I request you preform your magic.

If you're only getting 15-20 samples in 10 seconds of logging, your interface is way too slow and you're not logging useful information.

If the stock ECU won't report that from a request over CAN, you won't be able to read it. Tools like RomRaider actually break into the ECU and read memory addresses.

you can get both of those with techstream.
