Would someone know what these tables are for?

Interesting ...

Where do you get the info from, I would love to look this up myself so you have less work

shoot me an email. it was from japanese doc which had to translate and work out what was going on. Majority of the info for the RB/VG info came from here

actually the knock tables @ 7FE0 and 79E3 are small 3D tables and as far as I have found out the values have nothing to do with the actual ignition timing or amount of degrees retard.

They seem to be some sort of knocksensor filter/sensitivity values..

the x-axis represents 3 preset TP-values (0, 32 and 64) and y-axis represents 3 preset RPM values 0, 1000 and 3600 RPM

like this:

Hi Eric,

I could not find these tables in the Nistune menu ..
The only thing which comes close to it is this ->
(see attachment)

Is there also a low octane table?


Also there seems to be some 'on the fly' mechanism to retard ignition without using the knock maps.
My ignition and knock-ignition maps are identical, but still the ECU pulls the timing ...

I still hope Matt will find the 'knock register' within the code of the Z32, so we get some knock display in Nistune.

Many thanks ....

I messed up the lookup in that document

Should have been these ones:

HIGH_TIMING_ADVANCE_BETA,&H7E70,16,1,16,1,Beta Timing vs RPM
REG_TIMING_ADVANCE_BETA,&H7E60,16,1,16,1,Beta Knock Timing vs RPM

7E70 0D70 KLLHAD At the time of ratio BETA advanced angle ﾘ ﾐ ｯ ﾀ ｰ 1×16 HNREPM:400rpm Deg ** All 00s

Andrew - Those tables eric mention are here (same description as above jap document)

KNOCK_LIMIT,&H79E3,9,1,9,1,Knock limit (TP 0, 32, 64, RPM 0, 1000, 3600) (High)
KNOCK_LIMIT_SECONDARY,&H7FE0,9,1,9,1,Knock limit (TP 0, 32, 64, RPM 0, 1000, 3600)

These are in the base address file

I just dont have a 3D table class for entries like this coded up so just displaying flat at the moment

Hi!

Yes ... I found it myself in the meantime
Would you change the representation in Nistune to '3D'?

Also looking at Eric's table how would I translate your flat table to 3D?
(Do I follow to the right, or down?)

RPM 0 [1 2 3]
RPM 1000 [4 5 6]
RPM 3600 [7 8 9]

Alright ... the to the right
