Knock count firmware

[Matt]

BNR32 doesnt have a patch available (nor does Z32). they seem to do things differently so I've still got to look into those

So how can I check if the Knock detection is working or not??

[bj226]

Dear Matt, any update on the knock control for BNR32 ECU? I'm using it on my BCNR33 but it seems that the knock count based on the signal on stock knock sensors was just not working! I notice that I all along get 0 knock count no matter how I adjust the timimg!

Thanks and Merry X'mas

No update on that one yet. BNR32 and Z32 would be the next ones. I've gone through all the 91 vehicle types supported and added knock map highlighting in the code this side so far

Thanks Matt, looking forward to your update!

Yes, I to am looking forward to an update on the BNR32

Me as well

[Matt]

ok point taken! spent many many hours this week updating the main application software for better internal support of auxillary and misc sensors (including better implementation of knock counting)

[guricha]

any news Matt ????

How cool would it be to have knock detection and/or some counter .. maybe even the check-engine light flashing?
(I think the PowerFC does this?)

In the meantime you can set your knock maps to some very conservative values, this way you'll instantly notice
if the ECU accesses the knock maps (ignition that is)

From what I learned knock detection is somewhat between an art and science .. so we have to cut Matt some slack here

Especially no-one really knows how well the Z32 ECU works with the RB25 sensors ...

Cheers,

Yes, knock detection is certainly proving to be a curly one.

In the meantime yes, I use the same technique - drop all the values in your timing map to a very low value (I use 5 degrees) so that if the ECU jumps to the Knock maps you'll notice it immediately.

I used to use Knock Copy but this only confuses the issue cos you don't know when the ECU is using knock maps...

Any update on finding the knock issue out with the z32 board?

[Torque]

Yeah ... it seems not much going on with regards to knock detection ..

At least it would be nice to have some kind of 'beep' when the ECU switches to knock maps.
(this way you can drive the car and be notified ...)

Matt, if you need help for the Z32, I have the code available to lit up the CEL once it switches over to knock maps.

It's a real simple code change

[Matt]

Hey Eric

That would be great. It would give me a good start on modifying the 63xx series code base for these ECUs. If you could email me any info I will start looking into this in a few weeks. I'm full time on Nistune now so just sorting through my backlog (tax, enquiries etc) and then back to software/firmware fixes

cheers
Matt
