12p just works when you plug in the wideband and set the 0 and 5v air fuel ratios I've never had any issues. I just did a cammed 304 in a vr a couple of weeks ago went from 120rwkw to 196rwkw cam springs and tune the airbox was a restriction at that level even with hsv otr. With the lid off the box and no filter it gained 6rwkw haha

If anyone wants a XDF file categorized like the 11P one here it is.
no other changes made other than sorting everything into categories the same as 11p to make it easier to change from one to the other

Knock Count logging and wiring question.

Have a '165 computer running at boosted 4 cyl. Runs well, but I would like to add in knock logging if possible. I have a GM knock sensor and filter setup that was common on the TPI engines. Can I use this as an input for 12P to log knock counts?

Looking for some wiring advice and config changes to add this in.

Mark.

You need the knock filter on the memcal like the aussie ones, and its an audio frequency filter that is build to suit the engine the memcal is for and can not be tuned to a different engine type. I dont think what you have is compatible. If your engine has the same bore as the engine the factory knock board was built for you will get some results, but the factory system was early and doesnt compare to modern systems. Further if you've matched the bore but its a different engine your results will likely be worse than the so-so factory system. I would recommend you dont use it. You can see a pic of the right type of knock board here - its the white board next to the chip. viewtopic.php?t=214&start=120#p81644

I found the factory knock control system very hit and miss like Antus said, it's very early and primitive.

I find most of the time it triggers from gearbox noise and exhaust pulses when you have headers. And the worst part is, most of the time it doesn't even register real knock when I verified with knock headphones on the dyno.

I disable all settings related to knock and just tune in a little safety margin in the spark table with knock headphones.

If you want knock control it may be possible to run a external knock box like the G4 that HP academy showed years ago into one of the inputs and run a flex table to retard the timing but I think it will still be crude compared to modern ECUs

Yes I have used that knock filter on the PROM in the later GM ECMs I used (7730s). The external one is essentially the same, just external. I could match the bore up with a similar one from a V8 application.

I was curious to see if I could log any knocks and see.

If I was to use the PROM piggy back, then I connect knock sensor to ECM Pin? I didn't think the piggy back filter worked with the '165s.
